Backstory
The main protagonist of this story, Jio is a boy with great battle skill, great trust towards his friends and an ability to persevere, but he also has an obsession with money and is not soon to show his feelings, often hiding them or blaming other factors.

His dream is world domination, which other people often laugh at, calling it a child's dream until they see his abilities.

Jio started his life without friends, the people in his village forcing him to leave after the death of his only friend Jin's parents for which he was blamed. He was later trained in the wild by a wolf, known as Zero. However, after completing his training he was chased away again, giving him a chance to complete his dream.

His next friend, came in the form of Ruby Crescent, a girl in search of her father. At first, he helps her as a paid bodyguard, but leaves once she runs out of money. She ends up fighting a man claiming to be Satan, but the real Satan (sealed inside of Jio) easily beats him once Jio is knocked out. Once Jio is conscious again, he says he will follow her until she can pay him for saving her. He claims (in front of her) that he is only her bodyguard and nothing more, but Jio sees Ruby as a precious friend and even seems to have a crush on her. In chapter 45, he said that he was Ruby's lover and he also said he wanted to be near Ruby.

After having Ruby for a friend, Jio grows out to be more trustful, and slowly breaks away from his dream of world domination choosing to be more helpful and caring of others, quickly gaining more friends and meeting Mr. Wick and Mrs. Basil, which he sees as his father and mother (never having known his real parents). They were murdered by Kujaku, one of the Four Guardians of Zenom Organization.

In Rock Bird, Jio is defeated by Anna in the preliminaries but the officials allowed him to move up due to the demon inside of him. After Jio's last fight, Satan begins to awaken but Ruby calms him. Rock Bird's leader dubs Ruby his 'Key' and kidnaps her. An enraged Jio runs to the top of Rock Bird with Ball to rescue her. Jio finds Ruby on the wall with the 'Devil's Pain' curse placed on her. Jio defeats the leader, who was also a demon, but not before Satan takes control. Shin shoots a laser which causes all souls to leave their bodies. In order for Satan to survive Cross's attacks, he absorbs Ruby's soul and Ruby releases Jio. Ruby stays inside of Jio to protect him against Satan.

Post time-skip, he has become the leader of the cyclops village, and sets up a trade and supply route, next to sending 'some early cash' so that the village can survive, showing his leadership and skill with money. He currently is fighting Zenom together with the rest of the crew.

A running gag in the post time-skip is that Jio always seems to forget about Ball, although he remembers everyone else perfectly. During the assault on the Stea republic to rescue Ruby, everyone was split up in battle. After being reunited, Jio was relieved that both Cross and Mei were alright, but didn't seem to notice Ball (even though he was standing right next to them) What really made Ball mad was the fact that he didn't know if Jio was doing that on purpose to make him mad, or if he really does tend to forget him. One explanation is that Jio is confident in Ball's ability and doesn't worry about him because he knows his friend can take care of himself in battle.

After rescuing Ruby, Jio holds a conversation with her atop their ship. Apparently he had been trying to ask her out on a date, but whether Ruby accepted was never shown.

It is also shown that Jio is from another planet called "Eden" the same planet that all the recipes are from. It is also known that he is a special being that was created by Adam and Eve to Counter act the effects of the "Kabbalah". Jio is the container of Satan - the No. 1i Demon, as can be seen by his half-white hair and red eye. At first, Jio seems unaware of Satan's existence, not knowing why the people in the village hated him, while in reality it was Satan that killed the inhabitants. During the Entotsu City arc, Jio has a first 'meeting' with Satan in his mind, and Satan grants him the Devil's Mark, which appeared on the palm of his left hand, reading the number "666" with each six pointing in a different direction making a triangle. The Devil's Mark can be used as an O-Part and its effect is Absorb (Absorbing Spirit). After gaining it, he quickly used it against Wise Yuri.
 * Relation with Satan

While the mark gives Jio some of the most powerful effects, it also takes away a piece of Jio's soul, giving more and more control to Satan. During the Rock Bird arc, Jio finally loses control, and Satan is free, until he is forced to absorb the No. 10 Angel(Ruby), which keeps Satan imprisoned. Once the Angel is removed four years later, Jio seems to be able to fight Satan himself, perhaps by the power of Ruby's jade pendant infused in his hand, already showing the ability to suppress Satan before. In chapter 76, it is revealed that all of the recipes and Shin came from a planet called Eden, where 72 scientists tried to harness all the energy of the universe. To accomplish this task, the scientists made the two kabballahs and Shin, which have the power to aborb energy in the form of information. 20 scientists were in charge of various categories of information, and eventually evolved into the 20 angels and demons based on their category. Their lust for energy eventually led to the absorption of Eden. The scientist that became Satan desired all of the energy for himself, and began absorbing everything. Two researchers named Adam and Eve foresaw this, and made a program called FREEDOM to counteract Satan's powers. The program split Satan into two minds sharing the same body. One of them became Satan, who retains the scientists greed, while the other one became Jio Freed, who is the scientists consciousness. The name Jio Freed was gotten when the sign for the Freedom program fell and broke in two. The first half was FREED, while the OM half was further broken, resulting in the OM being split to look like a JI. Jio finally defeats the Satan inside him, and gains control of Shin. Along with the rest of the surviving angels and demons, Jio flies into space. Jio, being trained by both the legendary swordsman Kirin and the wolf Zero, has a unique style, being noted by a great deal of people including Kirin and Kujaku. Next to this, he also has skill in using the terrain, especially shown during his fight with Anna in Rock Bird. This, together with his O-part to multiply his energy, a pendant with over 100 different effects and the power of Satan, makes Jio a formidable warrior.
 * Powers and abilities

His O-Part is a boomerang called Zero (C rank) which is later upgraded by Kirin to Shin Zero (B rank) Zero's original effect was "Double" (double the power), but Shin Zero's effect is "Triple" (triple the power). After the time-skip his weapon is again updated, this time to Zero R, another boomerang type weapon that reacts to the amount of hatred in one's heart and changes shape accordingly.

His secondary O-part Mark of the beast seems to be very strong and getting stronger. He has even been able to take his power even further by what can only be described as an O-part fusion with Zero R and the Mark of the beast making his hand that of when Satan is released his left iris even changes into that of satans.

Ruby Crescent

 * Age : Start: 14,rock bird 15, Post-Rock bird 19, Post-Armageddon ??
 * Height : 155 cm (5'1")
 * Weight : 40 kilos (88 pounds, 6 stone 4 lb)
 * O-Part: Jade Pendant

A young treasure hunting girl who is researching the mysterious, legendary O-Part. She carries an extensive knowledge of ancient languages, and also seeks to uncover the mystery of her father Jack Crescent's death. She carries a necklace (Jade Pendant) her father gave her, which is revealed to be a S Rank O-Part with over 100 effects. She smiles almost constantly, because she says that after her father died, she realized that just crying and running away won't solve anything. She always worries about Jio and Ball when they are fighting against other O.P.Ts. Ruby shares a strong friendship bond with the two, but seems to have more intimate feelings for Jio, and she has known him much longer. She is later revealed to be Sandalphon the No. 10 Angel and her "father" is actually a traitor to the Stea government and is not really her father, just a man who was taking care of her until she awakened as the No. 10 angel, though she still considers him as her surrogate father. Her soul is absorbed into Jio in the Olympia chapters when Satan is fighting Cross and gets a fatal wound. Post-timeskip Jio and his friends fight their way into Stea main base and Jio is able to reverse the absorption effect and restore Ruby's soul to her body. She is now able to use her Angel powers, though they aren't complete as of the latest chapters. After Ruby is reunited with her father, the leader of Zenom, he claims to have no daughter, leaving Ruby distraught. After Jio arrives and saves the crew, Shin begins collecting all of the demons and angels, and later, even human's souls. Ruby takes the hit for her father and they both give a pinky promise, something Ruby refused to do many years before. Both were devoured by Shin and inserted into the Kaballah. Inside shin to save the world with the help of Jio, Cross, Zero and Jack himself they warped shin away from earth just as night fell disappearing into the void of space.

As the No. 10 Angel Sandalphon, she has currently shown the ability to shrink the Giant Ophan to a tiny size, then revert it back to normal while making some design changes. This however, is not the true extent of her abilities according to Cross. She is not however, an O.P.T. but has shown herself to be adept at treasure hunting (due to her background) as well as solving riddles as shown in the latest chapters. In a recent chapter, she was also seen using these shrinking powers by fighting one of the 4 Warriors of Zenom. In her battle, she was seen exhibiting enhanced strength and the ability to enlarge and shrink objects (such as rocks and etc.) with ease.

Ball
A strange kid with dreadlocks who loves round things and joins up with Ruby and Jio after the events in Entotsu City, where he lived with his parents and younger sister. At first, Ball loved to pretend to be an OPT and loved to show off. He was greatly surprised when Kirin revealed to him that he was indeed a true OPT. He then received his O-Part, called Cool Ball (C rank), and its effect is Magnet (Magnetism). Post time-skip, he wields a new O-part, called Tricky (B rank), which are smaller versions of Cool Ball that seem to resemble marbles. Ball is revealed to have a very good sensitive ear, and is able to distinguish different notes just by hearing them, although he can't play any instruments. He sometimes serves a comedic role in the group, as his occasionally perverted ways get him into trouble.
 * Age : 11 at the beginning,Rock Bird 12, Post-rock bird 16, Post-Armageddon ??
 * Height : 150 cm (4'11")
 * Weight : 38 kilos (83.6 lb, 6 stone)
 * O-Part : Cool Ball (pickle stone)Tricky

During the Rock Bird arc, Jio and Ball were pitted against each other in a battle. It was here that it was revealed that Ball trained himself everyday in order to match up to Jio's battle abilities. During the fight, Ball surprised everyone by showing just how much he had improved with his O-part, even discovering an advance form of its effect in the middle of the fight. Although he managed to get Jio to take him seriously (Jio stated that he would not need to use his O-part during the fight, but Ball proved otherwise to Jio and forced him (Jio) to fight seriously) and got a few good hits in, Ball still lost out in the end due to Jio activating Satan's power. His loss was not in vain, however, as Jio acknowledged him as a worthy rival after the fight.

He proved his power and skill as a high ranking OPT once again by taking on the powerful cyclops, Tsubame, with his third eye open, and winning. After this he gained the affection of Mei, although he is not aware of this and thinks she's just acting weird when she watches him with awe. In the Zenom base he fought against Franken and won, using Tricky's magnetic effect to take him apart from the inside out.

While not possessing the same level of physical strength of Jio, Ball has proven himself to be quite a capable fighter. Like Jio, after training with Kirin his reflexes, strength, and awareness were raised greatly. Unlike Jio, however, Ball has displayed a natural talent of handling his O-Part and it has been stated by Kirin and others that Ball's ability to control O-parts was much higher than others, including Jio's. In battle, Ball displays amazing cunning and strategy, using his O-parts magnetism effect to fool his opponents, often coming up with surprising plans in the middle of battle. He was even able to rival Jio during their fight in the Rock Bird arc. Due to his natural talent with handling, Ball is the one who often pilots the groups transportation vehicles.

Years after Armageddon, He has settled down with Mei and looks much like his father even facial hair. He still has his dreads but now uses a different head band pattern he seems to have gotten use to his new role as a father and had two children together, a son and a daughter. Their son has Mei's hair and third eye, and the daughter has Ball's black hair and Mei's regular eyes, either twin has the potential to become an OPT but from their genetic inheritance and other past examples it's most likely Jio will not be an OPT and Ruby will. they also wear a scarf around both of their necks that looks like Jio Freed's. (Much like Kirin and Kujaku, the seem to have different attributes from both parents.) He seems to have not upgraded Tricky after Armageddon as it's seen on the last page next to the book about Jio Freed. Ball seems well off living in a large house that has his own symbol, his outfit still also includes this symbol slightly modified.

Cross Biancina

 * Age : Start: 12, Post-Rock bird 17, Post-Armageddon ??
 * Height : 160 cm
 * Weight : 47 kilos, 7 stone 6 lb,, 104 lbs
 * O-Part : Justice (5 rings; thumb earth, index electric water, middle wind, ring finger force field, pinkie bomb)

Former commander of the Stea Republic SS Rank O-Part ship Shin (God). Cross lived alone with his younger sister, Lilly, after their parents left when they were younger. The two went to church often to pray for their parents' return. One day, Jio came to the village where Cross lived. The Satan inside Jio noticed Cross was the No. 1 Angel - Metatron, the only being he recognized as having the power to defeat him. So he erased the existence of Cross's village, including Lilly, who was actually a copy of the No. 10 Angel, and the Solomon's Key that would awaken Cross's angel form. Cross witnessed his village's destruction, and realized that it was Satan who killed Lilly. After his village was destroyed, Cross was taken by the Stea Republic onto Shin and promptly found out he was an O.P.T. He is an extremely powerful O.P.T., and so became the commander of Shin. He continued to search for Satan, and Satan's plan was to absorb Cross's hatred and enormous power after it had matured enough. However, that plan was thwarted by Ruby and her jade pendant, the real Solomon's Key, who awakened Metatron in place of Lilly and changed the hatred in Cross's heart to purity. His O-Part is Justice (C rank), which consists of five rings.

As of the beginning of the time-skip he was traveling with the rest of the Ophan Crew helping them look for Jio. As with most of the other characters after the time skip his appearances have changed, he has kept his short hair but has taken a very feminine look with his clothing and facial features outside of battle even being mistaken for a female by enemies.

He has recently re-met up with the famous hacker Ponzu who has taken Lilith's recipe nuclei into herself and brain washed him using it. Ponzu believed that she has been in love with him but he was so obsessed with Satan that he left without even leaving a note and without her confessing her feelings. Cross after coming to his sense removed the nuclei with Metatron and seems to have a touching moment with Ponzu. He has been sucked into the completed Shin, while inside shin to save the world with the help of Jio, Ruby, Zero and Jack himself they warped shin away from earth just as night fell disappearing into the void of space.

Kirin

 * Age:?
 * Height:?
 * Weight:?

A white-haired, pickle-loving hermit who is easily bored and lived on the outskirts of Entotsu City, famed for his knowledge about O-Parts (and repairing them) and his genius as a swordsman. His brother Kujaku claimed that no one has ever been able to wound him in battle. Despite his genius, he is not an OPT. Though, his abilities exceed those of most OPTs. A former Stea officer, he is now accompanied by his dog Jajamaru. After Jio, Ruby, and Ball departed from Entotsu City, Kirin decided to travel along with the three, because he wanted something to do. Kirin has been revealed to be the son of a Cyclops father and OPT mother, and is in fact the son of the younger brother of Mei's grandfather (see chapters 27 & 55). Kirin, unlike his younger brother Kujaku, has the Cyclops third eye on his forehead, which was open when he was born, and is very rare, if not completely unheard of. His weapon is a katana. It is widely believed by fans that he may be the Arcaido spirit in a new form due to his extensive knowledge about O-Parts and the fact that he his half human and half cyclops. As a child he was trained by his father to be a swordsman along with his brother.

Every day when his brother and he would spar, he would beat his brother until the day that his brother beat him after obtaining the power of the Adramelech demon, where he walked in shortly after his brother had killed their father. Still as a child, he attempted to stab his third cyclops-eye, in an attempt to be normal, and stop his brother's hate to him and his father, as the third eye couldn't be destroyed, he cut his left eye, blinding it, and leaving him with just two working eyes: his right eye and his cyclops eye.

Inside the Zenom base he fought with and defeated Kujaku with the help of Mei. After the battle Kirin left behind their father's katana for Kujaku, revealing that their father had intended for him to inherit the sword the whole time.

Amidaba
Nicknamed "Seven-Colored" Amidaba, former Stea Republic Army Officer. She is a skilled O.P.T. and friend of Jack Crescent and Kirin. She meets Ruby in the dungeons of Entotsu City and aids in their escape. She also helps out in the fight against Mekisis and Wise Yuri. After the fight, she tells them to go to the Ruins of Dust Storm and meet with a man called Wick. Currently traveling with Jio post time-skip. She appears to have O-parts embedded into her hands, but is capable of using many O-Parts. Her current O-Part is Rainbow. She has the ability to use any O-Part.

Jin
Jio's childhood friend that protected Jio when he was bullied by other kids. The same day that Jin told Jio they were friends, Jin witnessed his parents being killed by Jio in Satan form. He became extremely hateful towards Jio and wanted to kill him. He later became an O.P.T. for hire, and met Jio on a mission. During their fight, Satan awakened and told him the truth about his parents' death. When Jin realized what really happened, he forgave Jio and saved his life from a fire he started. His O-Part is Ashura (B rank), and its effect is Flame. Jin has two special attacks, fueled by his hatred of Jio: Black Flame Pillar and Black Flame Dragon. The black flames had a special property that allowed them to burn everything they touched, including a whole human. Later, Jin returned to take place in the Olympia tournament, and during the Olympia tournament, it was revealed Jin no longer hated Jio and was instead focusing on saving Jio from Satan. Also, the hatred that fueled the black flames of Ashura have been replaced by the more powerful blue flames. The blue flames had a property of being the most intensely hot flame, more so than normal red or orange flames.

Post-time-skip he is seen traveling with Futomomotarou after being saved by him during the Rock Bird arc. They can combine their fire and gas attacks to create a large explosion. Recently it has been revealed that Jin is in possession of one of a recipe nuclei of a demon which he says he personally single handedly fought and beat. It was revealed that it was a fake recipe made by Jack.

Zero
A lone wolf who has been banished by other wolves because he is an OPT. He taught Jio all he could of fighting and survival skills. He hates both humans and wolves, but built up a friendship with Jio as they share similar situations - they are both shunned by others of their species. His bones are C Rank O-Parts, and their Effect is Haste, but using them causes extreme pain to Zero. In post time-skip, he travels with Jio. It has been revealed the he is the No. 4 Angel - Zadkiel. His special power allows sacrificial wolves to take on the shape of another person and save them from an attack. The cloned wolf will die in place of the replaced person. The person will still feel the pain of their death ex; gunshots, laser beams, etc. He was sucked into the completed Kabbalah inside Shin which help start Armageddon which was stopped as Jio overcame Satan. Inside Shin, to save the world with the help of Jio, Ruby, Cross, and Jack himself, they warped shin away from Earth just as night fell disappearing into the void of space taking the effects of Armegeddon with them and saving the Earth....for now.

Mei
Member of the Cyclops, the original inhabitants of the O-Parts Hunter Planet. During the time-skip, and a few chapters post time-skip, she had a huge crush on Jio, and saw girls Jio talked to as adversaries. As a little extra, she actually considered Cross to be a rival as well. She acknowledged that the matured Cross is beautiful, female almost. Surprisingly, she and Ruby become fast friends, despite Mei feeling envious of her beauty and Jio's feelings toward her. She apparently met Jio during the time-skip when Jio was nursed back to health by her village. She joins the party with Jio (by sneaking onto Orphan) after the time-skip, and is now traveling with the party. Mei's older brother Tsubame, the former leader of the Cyclops village, disappeared around the time Jio entered the Cyclops village.

During the fight with Tsubame she unlocks the power of her third eye and with Ball's help is able to defeat her brother. After Ball fights with the changed Tsubame, Mei realizes that she used Jio as a replacement for losing her brother, and now shows affections and love for Ball. It is recently revealed that Mei's father was Kirin and Kujaku's cousin, making Kirin and Kujaku her second cousins. A recent chapter reveals that she enjoys sweets, and found the mayor of her village, her grandfather, extremely annoying.

Inside the Zenom base she, Kirin, and Jajamaru fought against Kujaku. Using her third eye she was able to take control of Kirin's katana and helped him deliver the final blow. She was later a witness to the potential Armageddon that nearly consumed the world and one of the last to hear Jio Freed's voice before he disappeared into the void for now. Years later she now has twins and has settled with Ball. Her face is never showed during this scene but her hair and outfit are clear give aways she tells her children the story of their youth and then ushers them to bed putting down the book next down to the Tricky O-part.

At the end of the series, it is revealed the Mei and Ball eventually get married and had two children together, a son, Jio, and a daughter, Ruby. Their son has Mei's hair and third eye, and the daughter has Ball's black hair and Mei's regular eyes, either twin has the potential to become an OPT but from their genetic inheritance and other past examples it's most like Jio will not be an OPT and Ruby will. They also wear a scarf around both of their necks that looks exactly like Jio Freed's. Much like Kirin and Kujaku, they seem to have different attributes from both parents.

Futomomotarou
A peverted fat man that uses the Mackerel Sword sword who Jio and friends meet during the Rockbird Arc. After the time skip he is traveling with Jin. He is the "Husband" of the Zenom four guardian Spika and has been shown to have thigh fetish. Spike has a need for attention and Futomomotarou pays attention because she has nice thighs and can create food with her O-part with a simple word. He has also shown to be able to gain animal traits by eating dumplings. He also caries extra top knots for his hair. He joined the Crew after becoming Spika's husband. His O-Part is the Mackerel Sword.

Jajamaru
Mainly used as comical relief, Jajamaru is the round dog of Kirin, and is ironically also an O.P.T. It was revealed that his biggest fear is one of Kirin's pickles coming alive and chasing him, and the thing that annoys him the most is Ball. After the time-skip he has a son who looks almost identical to what he looked like pre time skip (see below) and has become an enormous yellow wolf/saber tooth tiger like animal that is several times larger than a grown man.

Jojomaru
Jojomaru is Jajamaru's son. The only two differences between him and his dad is that their hair grows a different direction in front and Jojomaru actually likes Ball (Ball can even understand Jojomaru as if they speak the same language). He is also an O.P.T. who flies Orphan when the group is in a tight situation. He's always been seen on or near Ball and has taken his father's place as the comical relief, being a living afro puff, yet also being helpful in a battle such as being the one to show Ball the way to defeat Franken.

Amaterasu Miko
Amaterasu Miko is the President of Stea Republic and the main antagonist (although Lucifer took her place in the last chapter) of the series. She desires a world in which she is immortal and all thoughts are unified under her own. Often seen with a giant white tiger, although it is revealed that the body seen with the tiger is merely a robot formed of O-Parts. In reality, she had transferred her consciousness into the flying ship O-Part, Shin. After Stea's main base was attacked, Miko/Shin fled and dissolved Stea, taking over the body of Barisu to form a group composed of those on-board (including Ponzu). Placing some of her consciousness in Ponzu, she took over the body of Baku and stole the second half of the Legendary O-Part when Jio knocked it from Jack Crescents hands. Upon joining the two halves of the Legendary O-Part, the Kaballah and the Reverse Kaballah merged to form the true core of Shin, transforming its appearance. Proceeding to absorb all of the angels and demons present, Miko prepared to absorb all life (information and memory) on the planet and destroy the planet, aiming to achieve her goal of unifying all thoughts. Jio entered the core of the true Shin and battled the spiritual body of Miko, finally destroying it and erasing Miko's consciousness.

Dofuwa Longinus
A blind man, Dofuwa appears to be the highest-ranked and most trusted of Miko's advisor's. He was sent by Miko to stop Kirin and Amidaba, but was killed by Kirin. His O-Part is Sunrise.

Mishima Kagesuge
Mishima is the commander of Stea's operations at the North Pole (mostly research surrounding the Kaballah and the Angels). He has fused himself with his O-Parts. In his most recent appearances, he appears to have become disillusioned with Miko's dreams, and helped Jio and company free Ruby's body from her containment chamber, although it may have just been an exchange since the Legendary O-Part was taken.

Ponzu
Ponzu is a legendary hacker that Cross sought out for detailed information on Satan. She accompanied him back to the Shin and helped to answer his questions. She loves bathes. Post time-skip finds her still on the Shin under the command of Miko. It has been revealed that she had the No. 9i Devil, Lilith implanted into her body. "Lilith" has the ability to cause others to go berserk when they look into her eyes, and can cause cellular instability, which can kill anyone except for people with regenerative abilities. Her nucleus, however, was pulled out by Cross. It has also become known that she is in love with Cross and has apparently joined up with him, Ruby, Futomomotarou and Spika, becoming one of the Crew Of the Orphan. Ponzu tries to warn Jio that he is not an ordinary container and not to go into the Kaballah, but she too late as the Kaballah already devoured him.

Tsubame
Tsubame is Mei's brother, and the former leader of the Cyclops village. He fell off a cliff while fighting against Zenom operatives, and was taken for dead. However, he was rescued by Mishima, who helped him open his Cyclops third eye. He later reappeared briefly as a Stea agent to stop Jio and company, and the power of the third eye drove him mad enough to attack his own sister. He fought against Ball and Mei, and although he had the upper hand at the beginning, Ball's cunning and power combined with Mei's newly opened third eye resulted in his loss.

In the end, Mei used a trick he taught her by tickling his ears to make him remember and close his third eye. He apologizes to his sister and crumbles into dust. Before turning into dust, he calls out to Ball and tells him to watch over Mei for him, as it was Ball who reminded him how important it was to protect one's little sister.

Barisu
When Cross was still a part of Stea, Barisu acted as commander whenever Cross was away. Although he acted respectful, he evidently despised him and though he would be better suited to commanding Shin. During the Roc-Bird arc, he even fired Shin's soul-absorbing laser at the city, not caring about whether or not Cross would survive. After Cross defected from Stea post-timeskip, Barisu took his place as commander of Shin. However, it wasn't long before Miko uploaded her consciousness into the Shin, taking over Barisu's body and using his body to still maintain control of those on-board without revealing her nature as the Shin itself.

Jack Crescent
Ruby's father and a former Stea Republic Army Officer. He has betrayed Stea Republic and become a treasure hunter to track down the Legendary O-Part. Died in official record but is later revealed to be a traitor and commander-in-chief of the Zenom organization. Jack has the nuclei of both Devil No. 5i - Asmodeus and Devil No. 6i - Belphegor within him. He has shown great control of both and is able to release to any percent he wants, but to use both he has to split the percent between them for example in chapter 73 he released Asmodeus at 70% and Belphegor at 30%. He is also able to combine the powers of both for different attacks. In chapter 74 it's shown that the nuclei have greatly effected Jack's personality without someone there to keep it in check, and reverts fully back to the loving father Ruby remembers as they are taken by the fused Kabblah shin. It's also shown that he's had at least one nuclei in him since he intentionally left Ruby when she was a child, and was partly the reason he even left. He was sucked into Shin to help start Armageddon which was stopped by Jio. Inside shin to save the world with the help of Jio, Cross, Zero and Ruby, they warped shin away from earth just as night fell disappearing into the void of space.

Kujaku
The younger twin brother of Kirin and one of the Four Guardians of Zenom Organization. He is responsible for the Reverse Kabbalah project that Zenom is conducting, and is searching for the devils. He is sadistic in nature and envious about his brother's ability to use the Cyclops third eye. He is the Devil No. 8i - Adramelech. Kujaku is an OPT but is never seen using an O-part, as he usually relies on his demon powers instead. When he was a child both he and his brother were being trained by their father to become swordsman, but Kujaku could never win during sparing matches against Kirin until he found an orb hidden in his mother's grave that contained the powers of the Adramelech and used it. After that he was easily able to beat Kirin, although once his dad realized how he won the match he was appalled and was later killed by his son.

Post time-skip he made a brief appearance in front of Kaito and Shuri when they reached the Reverse Kabbalah while they were going to free Kaito's little sister from being sealed up inside of the Kabbalaha. Later he fought Kirin in the mirror ruins and activated his full demon form and used an ability that causes people to go through solid objects. As Kirin began falling through the ground, he told Mei to use her cyclops eye to project him through the air. Kirin used his mouth hold his sword to slice up Kujaku's demon body. Afterwards, Kirin gave Kujaku's sword, saying it belonged to him and that their father pushed him so hard because he wanted Kujaku to be better. After seeing his name carved on the sword, Kujaku sheds tears saying "I am not alone" as Kirin walks away In Chapter 75, just as the Crew of the Ophan was about to be absorbed by Miko, Kujaku used the sword to perform the ultimate technique their father taught them to sever the tentacles and save them. Joking that Kirin was as pathetic as always, he then dies on his feet smiling.

Rock
One of the Four Guardians. He distrusts Kujaku and is aware of Kujaku's ambition to take control of Zenom. He is the Angel No. 5 - Samuel, and as a result has the ability to remove collected demons from the dark Kabbalah. His eye seems to have the power to detect recipes and nuclei of both Kabbalah. In battle he appears to dual wield two pistol looking weapons which may or may not be O-Parts. On his back, he carries the O-Part 'Twelve Watchers', which emits twelve laser beams that Rock can control. . He showed his true form at the end of chapter 71, and has the nuclei of Samuel removed at the end of chapter 72

Spika
One of the Four Guardians. She is very quiet and polite, addressing Cross and Ruby as "master" and "young miss". She greets Ruby and Cross kindly and politely asks them to go home, and when they tell her the exit is behind them, she cheerfully tells them that the path behind her leads to hell, scaring the two. As they comically run away as fast as they can, she holds the ring around her neck to her mouth and her personality changes completely as she angrily yells at them to not ignore her. The ring takes sound waves from the air and creates giant letters that can be used for attacking. Certain words have different characteristics, such as the word "spike" creates spiky letters and the word "sticky" creates letters made from a sticky goo. She is fighting Ruby and is nearly caught by two halves of a rock moving towards her, but is accidentally saved by Futomomotaro getting caught between the rocks and becomes Futomomotarou's "wife". She and Futomomotarou often have little 'love scenes', comically scaring the rest of the crew. Spika now fights with the Crew of The Orphan because she is now 'loyal to her husband, not the Zenom'.

Spika's name is probably a pun on the English word "Speaker" which matches her ability to materialize words.

Franken Schultz
A guardian that looks like a robot with a large mask for a face. The other guardians call him Mr. Franken. Recently, it was revealed that the robot is an operated O-Part and a brain inside is the O.P.T. controlling it. Franken claims to have once been an ultimate warrior, and it was his father, Professor Brownie Schultz, who turned Franken into an O.P.T. Additionally, it seems that Amidaba knows Professor Schultz. Franken has displayed very strong abilities, such as the power to spin very rapidly, destroying objects. He can also shoot masks out of his mouth that fit onto people's faces and take control of their body, and he can use this ability to destroy people's bodies by literally tearing them apart. Also, it appears his O-Part can hold demons. He also keeps a number of masks that allow him to change effects when worn, such as fire and ice. He used to be a human child with a very sickly body and it was predicted that he would not live to the age of 10. His father created the O-Part body for him to allow him to live, but after Ball defeated Franken, Professor Schultz killed him, saying that Franken's brain had already reached its limit and he would have died soon anyway.

Baku
A chief executive of Zenom Organization. Baku appears to be Jack Crescent's most trusted agent, and seems to know a great deal about the nature of the Kaballah. His O-Part is the Magma Masks, granting him telepathy and teleportation when used with the two other masks possessed by his son and daughter respectively. Post-timeskip, in combat he was also shown to be skilled with knife-throwing and creating illusionary duplicates of himself, although it is unknown if the illusions are the effect of an O-Part or not. During Jio's battle with Jack Crescent, Baku was possessed by Miko in order to steal the other half of the Legendary O-Part, his face even transforming into Miko's. After Miko provoked him enough, Jio punched Baku's body and sent it crashing into a wall. It is currently unknown if Baku is still alive.

Wise Yuri
A lower-rank member of Zenom Organization. He infiltrated Entotsu City to monitor the excavation of the S Rank O-Part Mekisis. Being emotionally unstable, he has a tendency to kill people without hesitation, even fellow members of Zenom Organization, and gets a piercing on his tongue for every person he has killed. His O-Parts are two rings called Brothers, they each have individual effects that work in tandem: Remote Handling and a Dimension distorter. He can put his hand through the one ring and come out of the other. After Mekisis is excavated, Wise takes it over to fight Jio. He is defeated by Jio and then absorbed by Mekisis.

Museshi
A combat captain of the Zenom Organization. He was one of the many agents who were attacking citizens of Entotsu City while Mekisis was destroying the city. He was Ball's first real opponent in a fight after becoming an O.P.T, and ball was struggling at first, until he exploited Museshi's severe acrophobia. Museshi always bends down while walking because he thinks the distance between the sky and the ground is too far when he stands up. His O-Part is Hang.

Shuri
A former chief executive of the Zenom Organization. He joined the organization because of his deep hatred for the Stea Republic after he watched his parents being murdered by government soldiers when he was a child, and because of this, he joined Zenom to overthrow the Stea Republic. His O-Part is Race, and its effects are Handling and Ice. He used to believe that only material things exist, and that things such as feelings and heart were not real, and he froze his parents' bodies in ice as proof of their existence. After he fought with Jin and had his O-Part broken in the Rock Bird arc, he saw the error of his ways and left Zenom, barely escaping Kujaku, who tried to stop him by killing him. Post-timeskip his O-Part is not only repaired, but appears to have received a considerable upgrade. He is seen training with Kaito and has helped Kaito save Yuria, from Zenom.

Yuria
Age:Roc bird 16 Yuria was first introduced during the Olympia Arc. Contrary to many English translations Yuria is not Kaito sister as this is a common mistranslation. She is Kaito childhood friend or more likely lovers. She was the container of Lucifuge - the No. 3i Demon until recently when Kaito used the power of his overwhelming love for her to subdue the demon and remove it from her body.

Kaito
A participant of the Olympiad, Kaito was defeated by Ball. Yuria (devil No. 3i - Lucifuge), was taken by Zenom to be placed into the reverse-Kaballah. After the time skip, he had joined forces with Shuri, and the two planned to rescue Yuria and destroy Zenom. Kaito is an OPT who uses weight changing o-parts. Prior to the time skip he used Giant Knife, and uses Heavy Metal, heavy metal is a glove that becomes a suit of armor and kaito can freely change its weight to his will after the time skip when Giant Knife was destroyed.

Anna
A very beautiful women with large breasts. She is an O.P.T that participated in the Olympia/Rockbird tournament. At first, her reasons for entering the tournament appeared to be just to win at any cost, but she actually entered in order to reunite with the man she loved, who had won the Olympia tournament the last time it was held 4 years prior. Her O-Part is Tennyo.

Poison Joke
A man wrapped up in bandages like a mummy who made his first appearance in the Rock Bird arc. He is a serial killer who kills just about anyone he meets just for fun. It is later revealed that he was not always like this, and used to be a regular O.P.T. who was called on by his village to try and activate a newly unearthed O-Part, Biraiya. When the attempt backfired, he became extremely deformed, and the rest of his village turned on him, causing his personality to become the way it is now. He is eventually 'eaten' by Lucifuge and is later seen floating in the limbo of another dimension which is Lucifuge's stomach.

Jio (Ball's & Mei's Son)
After an Unknown amount of years after Jio Freed's brave actions to save all life on earth, Ball and Mei have a little boy named Jio. He has light curly hair and is of lighter skin, even with his father being of half dark skinned decent and Cyclops usually being dark skinned, and a closed cyclops eye. He is only shown in a modified version of his father's original appearance clothing with the half hollowed out half circle and a full circle in the middle. He and twin sister seem to hear the tales of Jio Freed and the Orphan Crew nightly, he also seems to share Jio Freed's red scarf with his sister. Either twin has the potential to become an OPT but from their genetic inheritance and other past examples it's most like Jio will not be an OPT.

Ruby (Ball's & Mei's Daughter)
After an Unknown amount of years after Jio Freed's brave actions to save all life on earth, Ball and Mei have a little girl, Ruby. She has dark straight hair in the style of her mothers and no third eye much like her granduncle, Kujaku naturally does. She is wearing a similar outfit to her twin brother which is a modified version of her Father's original outfit. She and twin brother seem to hear the tales of Jio Freed and the Orphan Crew nightly, she also seems to share Jio Freed's red scarf with her brother. she is the only twin to speak in the last pages. Either twin has the potential to become an OPT but from their genetic inheritance and other past examples it's most likely Ruby will become an OPT.

The Cyclops
The Cyclops are humanoids, and the original inhabitants of the planet where O-Parts Hunter takes place. Normal humans are descendants of space travelers. The Cyclops have long since hidden in their village, but are now coming into the open.

Unlike Cyclops' in ancient Greek mythology, Cyclops in O-Parts Hunter have two normal eyes, and a mark on the forehead. The mark will only open into an eye for a few Cyclops and grant them with incredible abilities. Other differences with normal humans include skin and hair color: So far all Cyclops have had white hair, and a brown/greenish skin. Since O-parts are the weapons of the space travelers, no Cyclops O.P.T.s exist.

Even while their ancestors were forced to hide from humans, the current generation bears no grudge against humans, recently making Jio Freed the village leader and starting trade routes with other villages for supplies and such.

Human/Cyclops crossbreeds can exist, often taking after one of the parents, having either human or Cyclops skills. A mixed child does have a human skin color, however. Not very much is known about Cyclops/human relations, expect that it's discouraged by the Cyclops people, possibly because of the tragedies that follow after human/Cyclops couples have children such as Arcaido, who killed 90% of the world population after dominating the world, and Kujaku, who killed his own father, the brother of the village mayor.
