The Ryōzanpaku Dojo


From left to right: (back) Apachai and Hayato; (middle) Akisame and Shio; (front) Kensei, Kenichi, and Shigure

The Ryōzanpaku Dojo is home to elite fighters who specialize in different styles of martial arts. The dojo is famous for its powerful members and is challenged by other dojos and fighters so often that it charges its challengers and has a waiting list. Despite this, the dojo lacks money; during the YOMI arc, it goes bankrupt.

Although they are all immeasurably powerful, the masters of Ryōzanpaku are also very eccentric and prone to immature behavior. They have trouble interacting with normal people, mainly because they unconsciously release massive amounts of ki, which sometimes makes the people they encounter feel nauseated. They are lazy procrastinators – only Ma and Kōetsuji are shown to bring in any steady income, while Apachai and Shigure have childish tendencies.

Kenichi Shirahama

Shirahama Ken'ichi (白浜 兼一?) Voiced by: Tomokazu Seki (Japanese), Josh Grelle (English)

  • First appearance: Battle 1
  • Type: Sei
  • Type: Katsujin Ken
  • Martial Arts: Karate, Jujutsu, Chinese martial arts, Muay Thai and Weapons (although he never uses weapons in combat)

Kenichi Shirahama is a sixteen-year-old boy who is currently in his second year of high school.[1] When Kenichi was six, he and his close friend, Ryuuto, watched as a six-year-old Miu defeated a group of thugs who were attempting to rob a local convenience store. They subsequently made a promise to become stronger. Although Ryuuto made good on the promise, becoming the first fist of Ragnarok as well as a member of Yomi, Kenichi forgot about it and was bullied frequently.

On his way to school one day, Kenichi meets Miu once again (though he does not recognize her), and the two soon become friends. At the start of high school, Kenichi joins the school's karate club, hoping to become less weak, but he is forced to do menial chores and is used as a punching bag. One day, he finally stands up to a hulking student, and the two agree to a match in which the loser will quit the club. With Miu's help, Kenichi manages to win, but he quits the club anyway. He joins the Ryozanpaku dojo, which Miu's grandfather nominally runs, and begins an intense training regime in several different types of martial arts. A main point of humour in the series centers around the multiple, varied, and imaginative training methods his masters devise in the name of making Kenichi stronger, most of which bring him to a point near death, but which he somehow manages to survive.

Kenichi fights the karate club's president twice, winning easily the second time, which, to his horror, causes his unwanted attention problem to snowball, since more powerful foes begin to take interest in him. The manga follows Kenichi as he continues to train, and eventually live, at the Ryozanpaku dojo, fighting more and more talented enemies.

Although it is consistently stated that Kenichi has no talent for martial arts, he more than makes up for it with his work ethic. Because of his hard work and his abnormally intense training regime, Kenichi goes from being considered the weakest student in his high school to being able to fight and defeat opponents with many years of training and even with borderline superhuman abilities. In the manga, his level is currently at the lower ranks of the "Expert", a step above a disciple and below a master – a fairly extraordinary feat, especially due to the fact he has only been training for a little over a year.

However, his strongest ability, according to the masters, is that he lacks any form of ki (killer intent). Because of this, many people who face him see him as a weakling and become overconfident, which usually proves their downfall. He can go unnoticed by even Master-class fighters for a period of time.

Kenichi is kind, compassionate, thoughtful, and moral to a fault. He is against violence and studies martial arts to protect others, and he adheres to a strict code of morals, which includes a refusal to hit women. Because of his kindness and empathy, Kenichi has made many friends, most of whom are former enemies, and has managed to unknowingly win the affections of Renka Ma and Li Raichi.

Kenichi favors no specific style, though he does abhor the use of weapons, and usually uses whatever fits the situation. However, he has used some techniques consistently.

Miu Fūrinji

Fūrinji Miu (風林寺 美羽?) Voiced by: Tomoko Kawakami (Japanese), Carrie Savage (English)

  • First appearance: Battle 1
  • Type: Dou
  • Type: Katsujin Ken
  • Martial Arts: Hybrid Martial Arts

Miu Furinji is a curvaceous 16-year-old girl who attends the same school as Kenichi and is currently in her second year.[2] She is the granddaughter of Hayato Furinji and the daughter of Saiga Furinji, the leaders of Ryozanpaku and Yami's One Shadow Nine Fists, respectively. How or when Miu came into Hayato's care is unknown, but she has been with him since she was six years old, if not earlier.[3] In these early years of her life, Miu learned martial arts from her grandfather and accompanied him on his missions to bring about peace.

Before Miu transferred to Kouryou, she attended a famous school,[4] but she was ostracized because all of the other girls at the school were jealous of her high grades, her athletic ability, and especially her looks. Because of this experience, Miu attempted to moderate her appearance by fashioning her hair into a plain-looking braid and beginning to wear glasses. Though she kept this facade going well into her second year, she eventually discarded it.

Despite being attractive, smart, athletic, and kind, Miu is very socially inept, to the point of having no friends before meeting Kenichi and practically no social life. Miu's social ineptness stems from her upbringing, during which she never had any time to make friends, and also from her home life, in which she is practically a live-in maid. Over the course of the manga, Miu manages to make quite a few friends due to her kind and friendly nature as well as Kenichi's help. Miu treasures her friendship with Kenichi but generally seems oblivious to his feelings for her, though she becomes jealous whenever another girl shows affection for him and has on various occasions hinted towards having deeper feelings for him. Miu has a great fondness for kittens and becomes openly hostile towards anyone who harms one. She is prone to making rash decisions when it comes to money-making.

Miu has proven herself to be an immensely skilled fighter. While her exact martial arts disciplines have not been stated, she has shown knowledge of several styles. Her fighting style is graceful and fluid, taking advantage of her agility, coordination, and flexibility, and makes heavy use of kicks. Her skills have been honed to the point where she will reflexively throw anyone who sneaks up behind her.

Hayato Fūrinji

Fūrinji Hayato (風林寺 隼人?) Voiced by: Hiroshi Arikawa (Japanese), R. Bruce Elliott (English)

  • First appearance: Battle 6
  • Type: Dou / Sei
  • Type: Katsujin Ken
  • Martial Arts: Unknown (but has vast knowledge of various styles and techniques, as well as having the ability to copy all of the enemy's moves easily)

Hayato is Miu's grandfather and the undefeated elder of the Ryōzanpaku Dojo. He is also known as mutekichōjin (無敵超人?, lit. 'superman with no equals') which is translated to "The Invincible Superman" in English materials. He is very tall, very muscular and possesses tremendous vitality despite his advanced age. Not much is known about Hayato's past, but flashbacks have revealed that he was very reckless and violent in his youth, claiming to have taken on 500 martial artists at once[5]. He also at some point had a son, Saiga, who sired his granddaughter Miu, whom he gained custody over. It has also been shown that Hayato used to travel the world with Miu and help out people in need. Around that time, he met Apachai.

Hayato is a kind old man but still possesses a reckless streak and can be very arrogant, the former of which is shown by his tendency to spend the dojo's money and to get carried away whenever he has a chance to showcase his strength. He also tends to convey his often over-simplified plans to others through a blunt manner of speech. He is fond of Kenichi, calling him "Ken-chan", and is the only one who apologizes to him for the hell that he and the others put him through. He has even given Kenichi his blessing to date Miu, should she herself agree to it. Hayato's affection for Miu is even greater; he has stated that anyone wishing to marry her would have to first defeat him in battle. Despite being a devout follower of katsujin ken, he once threatened to kill a man who was holding her hostage.[6]

Hayato is considered by many to be the most powerful man alive. Even when he uses only 0.0002% of his power, keeps his eyes closed, and splits his concentration and body movements, Akisame comments that he still is the most powerful man in the world.[7] In this state, he remains strong enough to rip a tree in half while simultaneously effortlessly battling Miu and Kenichi.[8] He is capable of throwing kicks so fast that cameras slowed down to 1/1000 of a second can only barely catch a glimpse of them,[9] and he can move fast enough to run on water.[10]

Shio Sakaki

Sakaki Shio (逆鬼 至緒?) Voiced by: Unshō Ishizuka (Japanese), Christopher Sabat (English)

  • First appearance: Battle 7
  • Type: Dou
  • Type: Katsujin Ken
  • Martial Arts: Karate

Sakaki is a 29-year-old master of karate who claims to hold 100 dan. He is a tall man who is almost always seen wearing a leather jacket and has a long scar that runs horizontally across the bridge of his nose. Little is known about Sakaki's past, but he has mentioned that he used to travel the world and fight, and he also at one point belonged to a group that consisted of himself, a French martial arts master named Christopher Eclair, and an Englishman named Mycroft. The three of them did a wide variety of work, which included working for the FBI and guarding important people. However, Sakaki opposed methods that involved killing or bringing harm to the poor, children, or the elderly, and the other two, who had grown tired of his stubborn refusal to do such things, tried to kill him but were subsequently buried alive in a desert as a result.[11] It is unknown when he came to Ryozanpaku, but he is one of the junior members along with Apachai and Shigure.

Sakaki is a very intimidating person even when he tries not to be, something that he does not seem to realize and is put off by whenever someone points it out. He has a kind and caring nature and is a very bad liar, which is shown when Akisame asks why he suddenly decided to teach Kenichi a fighting technique, and Sakaki replied that it was in commemoration of the anniversary of judo. He is embarrassed by trivial things, such as when Kenichi calls him sensei, even though he told Kenichi to address him so. Like the other masters, he can be quite childish at times and tends to get into trivial arguments with others, especially Apachai. He also gambles and drinks frequently and often places bets on Kenichi. At first he was strongly against taking a disciple, but he eventually warms up to Kenichi and shows much a great deal of concern for him, even going so far as to directly violate Ryozanpaku's rule prohibiting a master from involving himself in his disciples' battles.

Sakaki is an incredibly powerful martial artist. He his well-versed in multiple forms of karate and possess superhuman abilities, most evident in the fact that he can survive a fall from one of the top floors of a tall building without any noticeable injury.[12] He has yet to be noticeably injured in any of his battles, including his fight with Yami assassin Christopher Eclair and his brief encounter with Silcardo Jenazad, a member of Yami's One Shadow Nine Fists who was able to give Hayato Fūrinji a tough fight. Silcardo was so impressed by Sakaki's skill that he actively seeks a battle to the death.

Apachai Hopachai

Apachai Hopachai (アパチャイ・ホパチャイ?) Voiced by: Hiroya Ishimaru (Japanese), Sonny Strait (English)

  • First appearance: Battle 7
  • Type: Dou
  • Type: Katsujin Ken
  • Martial Arts: Muay Thai,and Muay Boran

Apachai is a 28-year-old master of Muay Thai and is known as the "Death God" of the Muay Thai underworld fighting circuit. He is extremely tall and powerfully built, has very dark skin, and is usually seen wearing a tank top and shorts with bandages wrapped around his hands and feet. Apachai has been fighting nearly all his life, fighting life or death battles in underground Muay Thai fights since he was a teenager.[13] At one point, he was an enforcer for a cruel pirate who fed Apachai while he was starving in a harbor in Thailand. (In reality, the man was throwing his food away, and Apachai, who just happened to be nearby, took this as a gesture of good will.) He served this man faithfully until Hayato Fūrinji brought his misdeeds to Apachai's attention. The two of them then defeated the pirates, and Apachai followed Hayato home and has been at the dojo ever since.

Despite his incredible size and strength, Apachai is very kind and gentle. He enjoys playing with children and animals and is very childlike himself. He has a habit of saying the phrase "apa" when he speaks and sometimes yells it while training or fighting. As a result of his violent past, Apachai initially had a hard time taking it easy on Kenichi, once almost killing him during a training session. Saddened by Kenichi's hesitance to train with him, he sought help from Hayato, who told him to pretend as though he were playing with children. The storyline reveals that that Apachai is unable to hold back because he was involved in numerous death matches when he was young, leading him to deal life-threatening blows on instinct. He is very fond of Kenichi and is the only master who consistently shows an open concern for him. Apachai has a voracious appetite, often consuming large meals with incredible speed, and even eating other people's shares. He can be easily distracted and persuaded by food. These gluttonous tendencies may stem from the fact that when he was young, Apachai would often accidentally break training equipment and have his meals taken away from him.

Apachai has been trained in martial arts since he was very young. He is extraordinarily strong, able to shatter stone statues and kick down trees without any apparent difficulty.[14] Despite his incredible size, he is blindingly fast, able to dodge bullets while fighting.[15] Even while holding back, Apachai was able to stalemate a master level fighter by the name of Kei Retsumin, a man who had once killed an entire village of people by himself; Apachai was later easily able to overcome him, once there was no one around to get in his way. He was also able to hold his own against Hayato Fūrinji for a time despite being quite young when the fight took place.

Shigure Kōsaka

Kōsaka Shigure (香坂 しぐれ?) Voiced by: Mamiko Noto (Japanese), Trina Nishimura (English)

  • First appearance: Battle 7
  • Type: Sei
  • Type: Katsujin Ken
  • Martial Arts: Weapons

Shigure is a 22-year-old weapons master. She is very beautiful and dresses in a small pink kimono; underneath she wears bandages over her chest and a fundoshi. When fighting seriously she dons chain mail. Shigure's past has been shown more in depth than any other of the other masters'. When she was a young child, she lived with her father in the mountains. Her father, who never named her, was a weapon maker and master of incredible skill, who made swords for Yami. Akisame, seeking to find the maker of a particular sword, met Shigure's father, who requested that Akisame kill him. When Akisame refused, the man forced him into a fight, which Akisame managed to win. Shigure's father stated that he wanted his daughter to see what kind of future a person like him, who had created things that had taken lives, would have, and he promptly took his own life.[16] After defeating some Yami members, Akisame named her and took her to live with his friend, an old man who taught her the Kosaka fighting style. She remained there until the old man died, after which Akisame took her to Ryozankapu.

Shigure is a very mysterious person. She speaks very little and has a habit of falling asleep on the rafters of the ceiling and also traverses atop them more than she uses the floor. She has little knowledge of most things outside of weapons and has trouble interacting with normal people due to her blunt personality and the fact that she always carries a weapon. Before Kenichi came to the dojo, she rarely interacted with any of its other residents except Akisame and Apachai and even refrained from such practical things as having dinner with them. Shigure is apparently quite fond of Kenichi; with him around, she smiles more often (though she still rarely does so) and interacts with the others more, eating dinner with them. She also didn't mind Akisame telling Kenichi about her past, saying that it was okay simply because he's Kenichi. The dramatic change in her personality has caused Miu to harbor suspicions about Shigure and her attitude towards Kenichi.

Even as a young child, Shigure had incredible potential, which Akisame noticed immediately.[17] She was incredibly fast and was able to defeat Sai Kagerou, a sword master, so quickly that he didn't even realize that he had moved. Despite her lithe frame, she is very strong and can cut weapons made of metal to pieces using something with a dull edge, such as a spoon.[18] She once cut a cannon off of a tank and then jammed it through its side.[19]

Shigure has a pet mouse, Tochūmaru, used mostly for comic relief, such as causing Apachai to be blamed for its stealing a lunch Miu made. Tochūmaru is shown to be extraordinarily strong for a mouse, beating one of Boris's men with nunchaku and, in an omake, beating a cat with its tail. While referred to as male, it is always seen with a feminine bow on its tail. Similar to other residents of the dojo, it seems to be knowledgeable of martial arts.

Kensei Ma

Ba/Ma1 Kensei (馬 剣星?) Voiced by: Issei Futamata (Japanese), Vic Mignogna (English)

  • First appearance: Battle 7
  • Type: Sei
  • Type: Katsujin Ken
  • Martial Arts: All Chinese martial arts (preferred fighting style is soft forms)

Kensei is a 41-year-old lecherous master of Chinese Kenpō. He is very short, balding, and always wears a hat. In his youth, Ma was very handsome and claims to have been very good with women. He has been training in martial arts since he was very young and was the leader of a large martial arts alliance in China, which has 100,000 followers,[20] which he left behind, regarding it as a nuisance. He has a wife and three children in China, including a 16-year-old daughter named Renka who followed him to Japan with the intention of bringing him back. He also has an older brother named Sougetsu, who is a member of Yami.

Kensei is a sly and perverted man, who tries to take pictures of attractive women, particularly Shigure and Miu. He often sells these pictures to Kenichi in the form of "data books", which usually turn out to be pictures of anything but the two of them. Ma seems to have a plethora of spying equipment at his disposal to aid him in such endeavors. In spite of his perverted and deceptive tendencies, he and Kenichi become quite close, forming a father-son-like bond. Ma knows Kenichi better than the others and is able to convince him to go along with their plans without resorting to intimidation. Kenichi has absolute trust in Ma and has stated that he has never questioned his convictions as a martial artist.

Ma is a very experienced martial artist, having been trained since he was very young, and purportedly knows all martial arts indigenous to China. In spite of his size, he is very strong, able to destroy a small bridge with a single kick[21] and to rend the flesh of Diego Carlo, a man said to possess a body hard as steel, with his bare hands.[22] He is very agile, capable of jumping from atop one moving cars to another.[23] Ma is also skilled in the field of medicine; he runs an acupuncture clinic and usually, along with Akisame, mends the wounds of Kenichi and the others.

The characters in his name Kensei are pronounced Jianxing in Mandarin, or literally "Sword Star". This differentiates him entirely from Isshinsai Ogata's moniker Kensei, pronounced Quansheng in Mandarin, literally "Fist Saint".

Akisame Kōetsuji

Kōetsuji Akisame (岬越寺 秋雨?) Voiced by: Jūrōta Kosugi (Japanese), Kent Williams (English)

  • First appearance: Battle 7
  • Type: Sei
  • Type: Katsujin Ken
  • Martial Arts: Aikijujitsu

Akisame is a 38-year-old philosophical Jujitsu master who was the first master willing to train Kenichi. He is an old friend of Miu's father, Saiga. Despite his seemingly small physique, he is known for having muscles built to perfection. He also has very good insight, often knowing if people are troubled or hiding something; he sometimes even knows what a person is thinking, which scares Kenichi. When he is in his "I Don't Wanna" Mode, he possesses an unbending stubbornness.

He is a famous and legendary artisan, who has mastered calligraphy, painting, pottery, and sculpting. He often invents contraptions that serve as both training devices for Kenichi and power sources for the dojo, including a treadmill generator. He also owns an orthopedic clinic and can reset bones with ease. Akisame speaks Russian fluently.



From top anticlockwise: Berseker, Loki and Number 20, Hermit, Thor, Kisara, Freya, Kenichi [non-member], Odin, Miu [non-member], Siegfried, Takeda, Ukita and Nijima [non-member]

Eight Fists

The Eight Fists are the leaders of Ragnarok, the eight strongest members of the organization. Each member wears a glove with a number (I – VIII) that corresponds to his position. Most of the Fists have adopted the names of legendary beings and figures from Norse mythology. The First Fist, Odin, has the backing of Isshinsai Ogata, who gives him special training not available to the other Fists. The first three fists, known as the "Three of Cards", are the founding members of Ragnarok. According to Natsu Tanimoto, they are on a completely different level from the other Fists.

After Ragnarok is disbanded, five of the eight fists (namely Freya (III), Siegfried (V), Hermit (VI), Thor (VII) and Valkyrie (VIII)) join or ally with the Shinpaku Alliance. Odin (I) joins YOMI. The whereabouts of Berserker (II) and Loki (IV) are unknown, though it is implied that Niijima has convinced Loki to infiltrate YOMI.

Bāsākā (バーサーカー?) Voiced by George Nakata (Japanese), Robert McCollum (English)

  • Type: Dou
  • Martial Arts: Street fighting

Berserker is the Second Fist of Ragnarok. He rarely speaks and has a calm disposition. Berserker never studied martial arts; he simply has a natural talent for fighting. He is said to be the most fearsome fighter in Ragnarok. However, he is afraid to fight Odin, believing that the latter is much stronger than he is.

He is named after Berserkers, Norse warriors. His sleeveless jacket features Norway's flag pattern. He displays a furious battle rage when aroused and the ability to negate feelings of pain through an adrenaline rush, which enables him to ignore his injuries and continue fighting.

Roki (ロキ?) Voiced by: Keiji Fujiwara (Japanese), Travis Willingham (English)

  • First appearance: Battle 48
  • Type: Sei
  • Martial Arts: Karate, especially utilizes the Spear Hand that uses Tame

Loki is the Fourth Fist of Ragnarok. He uses a Karate style that involves using all the joints in the arms. Besides being a powerful fighter, he is also quite intelligent, using information about his opponents to his advantage. Despite his strength, Loki prefers to win by using any means necessary; he kidnaps Honoka after learning she is Kenichi's sister. His ultimate goal is unknown, but it seems that destroying Ragnarok is part of it; he plants seeds of doubt among the Eight Fists in order to have Ragnarok in disarray. Loki also has "shadows", underlings who look like him; he uses them to distract and confuse opponents.

Berserker defeats him after Loki attempts a coup d'état against Ragnarok.

He is named after Loki, a trickster in Norse mythology.


See Shinpaku Alliance's Hibiki Kugenin


Natsu Tanimoto (谷本 夏, Tanimoto Natsu?), as Hermit, was the Sixth Fist of Ragnarok. He learned martial arts from Sougetsu Ma, Kensei's older brother. He is the president of the drama club at Kenichi's school. Tanimoto perceives popularity as a way to control people; he acts the part of a kind and soft-spoken student and is considered the school's "prince". He claims to have only joined the drama club to practice lying.

Tanimoto transports members of the Shinpaku Alliance to the D of D tournament, but his intention is not to participate but to find his old master, Sougetsu. He is briefly believed dead after his boat is blown up by the missile defenses of the private island where the tournament occurs. He later finds Sougetsu on the island and trains under him. He comes to the aid of the Shinpaku alliance in their fight against Fortuna. He also helps when Boris Ivanov leads a YOMI attack against the Alliance.

In chapter 353, Hermit is training to become a member of YOMI. In chapter 355, he faces and defeats temporary YOMI member Enshin Chou for the seat.

Taichi Kōga

Kōga Taichi (古賀 太一?) Voiced by: Mayumi Yamaguchi (Japanese), Greg Ayres (English)

Kōga, also known as Kōga the Kicker, is the youngest known member of Kisara's team. Unlike Ikki and Ukita, he seems to bear grudges against Kenichi, whom he plans to take down himself, and Miu, whom he calls "Neko Shojo" (Cat Girl). While he possesses a carefree attitude, he is very loyal to Ragnarok and is eager to deliver punishments to those who betray the gang.

Kōga was originally teamed with Takeda and Ukita as part of the Three Man Army. His current whereabouts are unknown.

Shinnosuke Tsuji

Tsuji Shinnosuke (辻 新之助?) Voiced by: Kazuya Ichijou (Japanese), Chris Rager (English)

  • First appearance: Battle 24
  • Type: Dou
  • Martial Arts: Koppou

Shinnosuke is an ambitious rival of Kisara's, often getting into arguments about who was stronger. He has a rougher fighting style and fewer techniques than Kenichi but greater experience. He had hoped to one day lead a gang stronger than Ragnarok and initially had hordes of men as followers, but after he was beaten by an unintentional sneak attack by Kenichi, he loses all but two of them. He gains respect for Kenichi, informs him of Takeda's impending punishment at the hands of Ragnarok, and warns him of Hermit.

Following his defeat by Kenichi, he goes into the mountains to train. He finds a master and is later able to obtain a victory – of sorts – over Kenichi before the D of D tournament. He refuses a rematch, saying that he's going to hold onto the victory for the rest of his life and never fight Kenichi again. His current whereabouts are unknown, though most likely he has returned to the mountains to continue his training with his master.

Tsukuba (築波?) Voiced by: Kiyoyuki Yanada (Japanese), Kyle Hebert (English)

  • First appearance: Battle 4
  • Name revealed: Battle 5
  • Martial Arts: Mixes of karate & boxing

Tsukuba is an upperclassman at Kenichi's school and a black belt in the karate club. His style of martial arts is sport karate, which focuses on the basics of karate and mixes in other techniques, such as boxing. He is the referee for Kenichi's fight against Daimonji and, following Kenichi's win, wants to test Kenichi's skills. He easily defeats Kenichi, but he is not satisfied with his victory because he finds bruises on his body after the fight. When he fights Kenichi a second time, Kenichi wins easily.

Takashi Furukawa

Furukawa Takashi (古川 たかし?) Voiced by: Isshin Chiba (Japanese), Joel McDonald (English)

Takashi first appears in episode 8 with a group that tries to capture Kenichi. When he fights Kenichi, he initially holds his own, but he snaps after he starts to bleed from Kenichi's punch and resorts to using a knife. Miu knocks the knife out of Takashi's hand with Kenichi's belt. Later, Takashi tries again to take Kenichi to Kisara once again, but Kenichi is able to overcome his fear of weapons and easily defeats Takashi.

Number 20

20 gō (20号?) Voiced by: Rikako Aikawa (Japanese), Monica Rial (English)

A master of spying and stealth, Number 20 is Loki's right hand girl. She is an excellent fighter and has a taste for airsoft guns. She dresses in military fashion and is never seen without her night-vision goggles.

The Valkyries

The Valkyries are Freya's followers. Each is a specialist with a specific weapon, which she was taught by Freya's grandfather. When first introduced, they were sent to hunt down Kenichi and Kisara. Later, they all enter the dojo and request to assist Kenichi against Yami, but Shigure points out that they're not strong enough yet.


Yami (?) is a worldwide organization of martial artists who use their skills to gain power, and in doing so have strong influence in crime syndicates. Yami is divided into a Hand-to-Hand Combat Division and a Weapons Division, which have not until recently gotten along. Their overall goal appears to revolve around, Operation: The Eternal Sunset, which appears to want to create a Third World War so their skills will not "rot away in these times of peace". They use elements as symbols.

One Shadow, Nine Fists

One Shadow, Nine Fists is the group of masters that controls both Yami and YOMI. They fight to promote the Satsujin Ken (killing fist), which they believe is the true way of martial arts. Silcardo has mentioned that the only reason they remain together is to avoid fighting each other.

  • Nickname: Odin (Ragnarok and YOMI Nickname)
  • Martial Arts: Ancient Martial Arts; also well-trained in Karate and Boxing

Ryūto, as Odin, was the leader and the strongest member of Ragnarok. He is currently a member of YOMI and has mastered Seikūken (制空圏 lit. sphere/circle of created/built void/space?), a technique which allows him to create a barrier that can neutralize attacks.

Ryūto was Kenichi's friend when they were young, before Kenichi moved out of the neighborhood. They witnessed Miu's martial arts skills when they were six years old, prompting them to make a vow to become stronger. He had coveted the Yin-Yang badge Miu gave to Kenichi and challenges him to fight for its possession. Ryūto defeats Kenichi and takes the badge.

Later, when he faces Kenichi again, Kenichi appears to have the upper hand until Ryūto shows his true strength. Kenichi's skills then prove to be no match against Odin's Seikūken. Kenichi manages to overpower Odin by imitating his masters' style and techniques, but Ryūto becomes enraged and combines the ki of both Sei and Dou to and once again overpower Kenichi. Doing so places a great strain on Ryūto's body, and eventually he is unable to avoid Kenichi's final attack. As a sign of his defeat, he gives Kenichi his Yin-Yang badge back.

The self-inflicted damage of combining Sei and Dou turned his hair white, blackened one eye, and left him wheelchair-bound, but he remains a formidable opponent, able to execute his Seikūken and Gungnir techniques despite his condition.

He is named after Odin, the chief God in Norse mythology.

The Shinpaku Alliance is a group of fighters created by Niijima Haruo in order to facilitate his goal of world domination. The name comes from the first characters in Niijima (新) and Shirahama (白). The alliance is first introduced in episode 21 of the anime, when Niijima comes to Kenichi's rescue in his fight against Kisara's group. The Alliance is composed mostly of students from Kouryou high and converted former members of Ragnarok. Following Odin's defeat and the subsequent dissolution of Ragnarok, the Shinpaku Alliance is able to cement its reputation as the strongest fighter group in town.

In the YOMI arc, the Shinpaku Alliance participates in the D of D Tournament and manages to reach the final round of the "Chi" group. However, because of the injuries sustained by its core fighter members throughout the tournament and their final opponent being Shō Kanou, the Alliance chooses to forfeit the match.

The Alliance initially used Kouryou High's physics laboratory as a make-shift base, but as the organization grew, it moved to Kisara's former base. After the D of D tournament, Niijima officially rented the building, telling Kisara's dad that they were trying to save her from the world of delinquents.

Yami and YOMI consider the Shinpaku Alliance part of Ryōzanpaku.

He is very adept at dodging attacks and running away. Despite his cowardly tactics, he has shown himself to be a cunning individual and a skilled tactician. If forced to battle, Niijima relies on hit-and-run and psychological tactics to un-nerve his opponents and render them more vulnerable. His is so skilled, that both friend and enemy have complimented him.

His senses are superhumanly acute; he is able to "scan" individuals by observing them for a few seconds, learning a wide variety of physical, mental, emotional, and other information about them.

Takeda, also known as Takeda the Puncher, is part of the Three Man Army with Kōga and Ukita and used to be a rising boxing star. However, an incident where he came to the aid of his friend caused harm to his left arm, leaving it paralyzed. He fights Kenichi to test how strong Kenichi is, but Kenichi defeats him by attacking his lower body, which is a boxer's weakness. Kenichi spares him and takes him to Akisame's clinic, where Akisame fixes his left arm. Takeda acknowledges Kenichi's strength and quits Ragnarok to become a pro boxer once again. He later joins the Shinpaku Alliance and comes to Kenichi's aid on several occasions.

In the second arc, Takeda becomes desperate to find a master similar to Kenichi, who has four of them. Eventually, he finds James Shiba (ジェームズ 志場 Jēmuzu Shiba?), an underworld former boxing champion, and trains under him, fighting in underground matches. Training under James dramatically increases Takeda's skills. He later participates in the D of D tournament as part of the Shinpaku Alliance and wins his first match in the quarterfinals of the "Chi" group. However, he is defeated and severely injured by Shō Kanou during an attempt to rescue Miu Fūrinji, causing him to forfeit the remaining matches.
