Plot
Tadashi is in his second year of junior high school and is a member of the handicraft club and loves nothing more than knitting. Unfortunately he's in a secret relationship with Saya, the leader of a notorious all-girl gang, who says she will kill him and herself if anyone is to find out about it.

As the plot progresses the power of the relationship not so subtly shifts from Saya to Tadashi, in several cases debilitating Saya's ability to act and causing her to have a nose bleed and faint at the thought of receiving affection from Tadashi.

Main

 * Saya Angelica Ikushima
 * Also known as Demon Head Saya. She is the leader of the all-girl gang called the Onigashirashu and is one of the biggest delinquents in the prefecture. She possesses superhuman strength as she is able to destroy a wall without thinking, when she is angry enough she becomes strong enough to even hurt the Invincible President or sorry enough she can cause a 3 magnitude earthquake, practically immune to harm and can compress snow into a ball harder than steel. She harbors feelings for Tadashi, but has to hide it to keep her impression on her gang that she is the strongest and biggest man hater of them all as she has stated to Tadashi that if they are found out of their secret she will kill him and herself. However after she is away from her friends and alone with Tadashi, she has a sweet love-struck girl personality, and usually asks to be punished in some life threatening way for harming him earlier to keep up her image (chained and waited down before going into a pool, asking him to break her arm, etc). She loves him so much that she couldn't get within 100 meters of his house without fainting and blushes deeply anytime any close action between them happens or is suggested, where her blushing can cause everything around her to heat up to the point of causing an onsen to turn to steam. Later in the series, she has been unable to compose herself as she used to when she sees Tadashi, often blushing and standing up for him. Her cooking skills are extremely terrible, for those who eat her recipe will suffer extreme pain all over their body and faint and the drinks she makes its described to be five times worse than her food (the only person that thinks it's delicious is her sister Cupid where Tadashi suffers through it as he is happy at the fact that she makes homemade lunches for him). She is also terrified of dogs, ironically calling them demons. It's revealed she extremely rich, her father running a very successful electronics company, and has a little sister named Cupid, though it appears that she doesn't like her father, calling him Old Man. How she styles her hair makes it look like she has two small horns coming out of her head, probably a reference to her "Oni" status. Because of how Saki's lack of strength gets so much of Tadashi's attention and because of a desire to be taken care of by him, she has taken up the habit of acting weak or sick from time to time. It is revealed that she first met Tadashi after he fixed her jacket when she ripped it and how their relationship began. It is also revealed that when Saya And Tadashi started their relationship she did have tsundere personality towards him and denied having a relationship with him claiming they were only friends. After being attacked by Momo, she cut the rest of her hair off where it is right below her ear, something she likes since her head feels a lot lighter, though it regrows after eating a special seaweed grown by the Student Council President's grandfather. A running gag is when she thinks about something romantic with Tadashi, she will faint and cause a crater where she falls or if severe enough she will have a nose bleed and lose gallons of blood. This as well as whenever she imagines a scenario or a memory of their time together, she always sees him as an angel like figure or herself the size of a small doll. This as well as a new habit of believe any girl (including her gang members) also have feelings for Tadashi, though ironically thinks that Saki doesn't.


 * She later takes up a disguise as a first year girl named Angie who is interested in the Arts and Crafts club, this being so she can be closer to Tadashi as she realized they rarely spend any time together. However she has realized with this personality she is able to say things she would normally be too embarrassed to say to Tadashi, as well as "onidereing" as she calls it after she goes back to her Saya persona from the memories. She can't be tracked down when disguised due to a lack of horns because they covered by a head band. Because of how effective this persona is, she accidentally created a love triangle between herself and this new persona for Tadashi's heart. She is unaware that Tadashi knows Angie is herself and is only playing along.


 * Tadashi Imamoto
 * Tadashi is the main protagonist in his second year of junior high school and is a member of the handicraft club who loves nothing more than knitting and his skills are good enough to make stuff animals. Unfortunately he's also in love with Saya, the leader of a notorious all-girl gang known as the Onigashirashu. Later on in the story, he becomes the vice-president of the school council (he didn't want to do this and also wanted to reject it, but he didn't have the chance). He is a very good hearted guy, as he will go out of his way to protect Saya or anyone else (though if it's a girl Saya usually gets jealous). While doing his duties as the Vice-President, he acts as somewhat of a personal servant to Saki since she is so weak when she does any manual labor he describes it as if she "is in a death struggle". Tadashi is identical to Kinoshita's example picture of the ideal male student, to the point that, when "purifying" two males deliquents, he essentially makes two copies of Tadashi. In a recent chapter, when drawing Saya Tadashi's picture looked like a realistic version of her and is called a realist. He truly does love Saya, and will go out of his way to protect their secret relationship or her in situations where he can.It is later revealed in chapter 49,Tadashi has a doll of Saya with him at home. He also becomes depressed when he is unable to spend time with her and has kissed her (twice so far) while she slept. Also when he describes his girlfriend to others, he often states how she might come off as tough but is a very sweet and cute girl, as well as the type of girl that if she had to chose between him and her friends, even if it was to save them from falling off a cliff and only had enough strength for one, she would try with all her might to save both. He then reveals to Angie (Saya in disguise) that at first he was afraid of Saya when they first met, but overtime he quickly fell in love with her.

Onigashirashu

 * Yuna Suzune
 * Yuna is a member of the gang, and is known for her samurai garb, large breasts and eyepatch (when she doesn't wear her eyepatch her hair covers her eye). She is often seen wielding two bokutos and very skilled with it, which she treasures as it was a gift given to her from her brother when she was young. She is also the most protective of Saya, going as far as to dress up "lady-like" to fool Saya's sister, and at practically any moment will come and fight (most of the time it being Tadashi under a misunderstanding). She is displayed as a tomboy to the point some believe she is really a guy, though she has a desire to appear more girly. However she usually attacks anyone nearby out of embarrassment after doing something she considers girly. She has a developed a crush on the Student Council President after he told her that if anyone made fun of her for being more girly he would "purify them", but will try to beat him out of embarrassment, even if she thinks about him in another room she will run over to where he is and beat him. She is considered dumb, as she nearly was able to figure out that Saya and Tadashi were dating, only to stop because her head started to hurt from thinking. She has a brother who is a cross-dresser, where ironically he is mistaken to be a girl, looking like a younger and more feminine version of Yuna, while wearing women's clothing. However, he is much stronger than her and inline to inherit the family Dojo, who wishes to change it to be completely girly. This also shows the reason Yuna first joined up with Saya was because her amazement of her strength and her wish for Saya to train her so she could defeat her brother and this also explains why she is the most battle-hungry member of the gang. She has a habit of grabbing Tadashi to where his head is against her breasts, though she seems to be unaware of this habit. She has also became addicted to mushrooms after eating them, even eating poisonous ones though she appears to be immune to them. She also loves eating chicken, something she likes to keep secret because of Momo's love for birds.


 * Mitsuki Asobiya
 * Her child-like appearance tends to fool people, but she is a master of guerilla warfare. She loves three things: Saya, to a perverted nature, often trying to look at her panties, kissing a doll version of her, and usually found sitting on her lap in class, snacks to where she could eat an entire box of chocolate bars in a minute, and bears, where she constantly releases some from the zoo, distracted by anything bear-like to the point she can be summoned by holding out a teddy bear and has a special flute that will call them. Also when wearing a bear costume she appears to gain certain bear-like abilities. Her weapon is a toy hammer with a cute bear's head on it, but the toy hammer will become a scythe when she is in her serious mode, where in her serious mode she can easily defeat Yuna. Though she looks and acts like a little girl, since she is attending the same school she might be their age or have skipped grades, however this doesn't seem to be the case since she always scores a 0. After Tadashi gave her a stuffed bear he made that she affectionately calls Kumarou, she has become friends with him, now calling him Nice-moto and asked him to make her a stuff doll of Saya with glasses (one he keeps a few of as well). This making her the "first" Onigashirashu to befriend a male. She was referred to as Ojousama, suggesting she might be rich or related to yakuza. She has a desire to own Cupid's bear Kumael. She usually bickers with Yuna about the simplest things.


 * Momo Akitsuka
 * Momo is the spy of the group, and always wears a bandanna over her face, very thin legs which are covered by a long skirt and she fights using a large two prong sword connected to a long chain. She has a very laid back demeanor. She never speaks, though she can and mimic voices perfectly, but she actually knows that Tadashi and Saya are in love, and in her own way tries to help them, sometimes exhaustively preventing anyone from disturbing their lunch date from the shadows. She was a former member of the gang "The Haou-Sou" which sent her to spy on Onigashirashu so when the time was right she could kill Saya, her name as part of the gang was the Third Haou "Momo", her mission was to become friends with the members of the gang and specially befriend Saya so that she could not attack one her friends, so her original gang could take take the heads of "kings" one them being Saya. But as the showdown between friends, she realized that all the other members really liked her as part of the gang and apologized to her for not noticing sooner that she was suffering as to betray them, she could finish her mission accepting that they are truly her friends and was welcomed back. However, because of her acts as a spy, the Haou-Sou know of Saya and Tadashi's relationship. She also had a part-time job, only to be fired by the plan of Tomeo Kinoshita, the school council president. She also seems to be involved with the student council under the alias Sumomo, where Saki is the only one to point out she is Momo where everyone else thinks she is wrong, but this could either be because she wants to infiltrate it or just act as a normal student. She has a love for birds, especially an anime one called Piyoto and is No. 1 in the fan club, even her helmet as part of the Haou-Sou resembled a bird's head.

Student Council

 * Tomeo Kinoshita
 * Tomeo is the president of the school council of Tadashi and Saya's school. He has rehabilitated 999 juvenile delinquents so far, and targets Saya and the Onigashirashu to accomplish in rehabilitating 1,000 juvenile delinquents, though he seems to do this simply by changing their appearance to match the "ideal" student. Tomeo is basically immortal, an ability he attributes to his belief in justice, which cannot die. However, when he realizes that he himself done something wrong, he becomes full of self-hatred and is injured via a lightning bolt that strikes him. He is often seen praying to an odd statue with the letter J on its head, calling it the god of justice, every time he seeks guidance. He is considered the worst enemy by the Onigashirashu. He later selects Tadashi to become the vice-president of the school; the position was open because he is so obnoxious that no one wanted it.  Tomeo is contrastly surrounded by evil spirits, hinted at earlier when the Evil Ward charm Youko gave Tadashi burst into flames when he entered the room, and later directly stated by Shuu. He is actually a good hearted guy, but what he does to help is often considered extremely annoying by others. And though seemingly stupid, he has displayed a good insight on people, he defended Yuna's desire to be more feminine, and was able to tell her brother Yumi was a male at first glance. Also he scores a perfect 100 on tests. His passion for justice seems to cloud his common sense, demonstrated when he is overjoyed when Yumi Suzune challenges his position, even offering his support, before Tadashi reminds him that he will no longer be the president if he wins. He has long white hair that is(ironically) clearly against the standards of the school. He has a grandfather who looks very similar to him (besides being older and having a mustache), who lives near the ocean. He is just as Justice happy as his grandson, probably being the reason for his grandson personality.


 * Saki Nijinose
 * The Student Council Treasurer and granddaughter of the principal. Like her position, she often thinks of how much something is going to cost, yelling at Yamata for kicking the metal door because overtime it could cause rust and have to be replaced which is expensive. She keeps track of the damage of what the gang causes and gives them a bill every time she runs into them. Saki is portrayed as being extremely weak and delicate, as she couldn't open a door Mitsuki could easily and just by trying injured her fingers, though Saya is jealous of her lack of strength because of all the attention Tadashi gives her from it. In a way she is displayed as Saya's opposite. Tadashi often bandages her which causes jealousy from Saya. Though if she gets angry enough, she displays a terrifying power and swears a lot, though she appears to be unaware of this. This scared even the Onigashirashu and Student Council to the point where they behaved for a whole week after the incident. She appears to be the only competent member of the Student Council, where the students will talk to her with issues rather than the President. Tadashi helps out Saki a lot because of her weak state and his helpfulness lead her to fall in love with Tadashi. This lead for her to cling and protect Tadashi which made many people believe they are dating. She first started to show feelings for Tadashi where she went to confront Saya (not knowing this was because of their date), speaking up to defend him, and going into a dazed state when she sees him. Her feelings for him have gotten so strong that she tries to prevent a situation where they are left alone together or where Tadashi would see her in more revealing clothes like a swimsuit. Due to Tadashi helping her everytime she asks and Kenji's words suggest that she is slowly getting fat, saying her legs make "squishy sounds" as well as her habit of adding chocolate to whatever she eats, calling it her life force. Because of the sudden interest in getting her legs thinner, she has a habit of believing people are pointing out that she has fat legs. Both Hibari Imamoto and Mitsuki refer to her by the nickname Muchiko.


 * Shuu Yamata
 * The Student Council Secretary, described as "cool and mysterious" by the President. He always carries a cross sword (later revealed to be a radish) and has been said to use it on the President, who doesn't mind since he is invincible. He later states he is a Spirit Hunter and regularly attacks the president because he is surrounded by evil spirits, being the main reason he joined the student council was to exorcise the spirits from him. His exorcism techniques involve housekeeping and kitchen utensils; as such he is also a good housekeeper and cook, to the point that Tadashi calls him an aspiring househusband, even introducing himself as House Dad. He also seems to know a lot of good ways to save money this shows he does not like to waste it. He is rarely seen and will appear suddenly when a spirit appears, this is due to him exorcising spirits around the school.

Haou-Sou
The Haou Sou (meaning the one supreme king) is a rival gang that aims for the defeat of the Onigashirashu. To that end they had Momo infiltrate the Demon Head Gang to get close to Saya and eventually kill her. But Momo became too friendly with the gang and defected from the Hao Sou at the last minute. They each wear an animal helmet based on the Chinese constellations. Because when Momo was their spy, they know of Tadashi's and Saya's relationship, believing that has something to do with her sudden increase in strength, so their overall plan is to take control of all the gangs in all the schools by inciting the students to protest against mixed sex education, ultimately splitting them up. However it has been noted that they could be doing this solely for the reason to not interact with the opposite sex because the Haou-Sou has trouble interacting with the opposite gender.


 * Tatsumi Amane, a.k.a. Tenryu "Heavenly Dragon" "The Azure Dragon of the East"
 * He appears to be the leader of the Haou-Sou. He wears a helmet that seems to look like, or represents a Dragon, and has a hard time seeing while wearing it, being a running gag that he is facing the wrong direction when talking. He looks similar to Saya. He is actually quite handsome, but his gynophobia is so extreme that he sweats profusely when around girls while not wearing his helmet. He states he developed this after his secret girlfriend dumped him over her friends, though this is most likely a lie to split apart Saya and Tadashi, this is later confirmed to be true by Aoi as he desires Tadashi to be happy, seeing that as to kill Saya and not to start hating the opposite sex like he does. He joined the Student Council after the President offered him a position after seeing how quickly he stopped the ruckus (which were caused by his cohorts) to be Vice-Vice President, though he constantly decides to drop out while working around Saki. Though recently he has discovered that Saki has a crush on Tadashi. He keeps coming up with plans to bring them together to ultimately break up Saya and Tadashi, but is constantly stopped because of his gynophobia. The only people that don't activate his gynophobia is Aoi and Momo, this is because at one time they were teammates which he states "teammates are alright".


 * Toraya Akito, a.k.a. Koou "Tiger King" "The White Tiger of the West"
 * He wears a Tiger helmet and the second Haou-Sou. He is the tallest of the group. He goes into a horrifying love-love mode with any girl who comes in contact with him, and snaps out of his girl-craziness trance when he hugs Tatsumi. President Kinoshita thinks Toraya is Yuna's boyfriend, though this is mainly because of the incident where she touched him. His　name is a pun off his title, as Tora means Tiger in Japanese.


 * Kamehiro Aoi, a.k.a. Koukaku "Armored Horn" "The Black Tortoise of the North"
 * Her helmet is supposed to look like a Tortoise, or symbolizes it and the fourth Haou-Sou. She comes from Akita Prefecture, and is mortified to have boys hear her speak in her dialect when she gets excited, to the point of beating them up because of it. She doesn't set off Tatsumi's gynophobic reaction, because "teammates are alright" even though Akito falls for her if she touches him and she beats them up if they hear her speak in her dialect. Aoi has been developing a more urban attitude and broke off from the Haou-Sou. 　Her　name is a pun off her title, as Kame means Turtle in Japanese.


 * Momo Akitsuka, a.k.a. Third Haou "Momo" "The Vermillion Bird of the South"(former member)
 * She was a member of the Haou-Sou. Her mask is supposed to represent a Phoenix. She was a spy sent by the Haou-Sou to get information to take down Saya. Even though she was going along the plan with Haou-Sou, she could could not take down the friends that she made in her 1 year mission and she was accepted back into Onigashirashu after resigning from her original group. It is currently unknown what is her reason joining this group in the first place because of their goal as to separate mixed sex education. She also knows all the weaknesses and secrets of all the members Haou-Sou, and uses this to keep them away from Saya and Tadashi.

Tadashi's Family

 * Hibari Imamoto
 * Tadashi's mother. She is a very energetic woman, where because of this she gets along with Mitsuki very well and both refer to each other with the Japanese honorifics chi. She has a habit where once she has set her mind on something, it is impossible to change it. Where in one instant even though her son told her a large squid crushed their car, she believed he stayed at the beach because he was with a girl, even when the squid was right in front of her. Despite her eccentric personality, she appears to have a good insight on people, as it is believed that she knows of Saya and her son being together. She is a pilot and seems to work as a detective, as she was working on a serial killer case.


 * Mr. Imamoto
 * Tadashi's Dad

Others

 * Kenneth Garcia
 * Leader of the hacking Club that Tadashi is apart of. Saya is usually jealous of her because it appears to her that Youko would make a better girlfriend to Tadashi (or this can just be because of any girl being around him in general). It would also appear that she does like Tadashi, as she says she would support him as Vice-President while crying. She returns when she asks Tadashi to help teach the new club member Angie (Saya in disguise) sewing.


 * Miko weak
 * Is a little girl and little sister to Saya whose father runs a successful electronics company called the G.I. Group. Unlike her sister she likes to show off her wealth by having her robot teddy bear fly her to school and lay a long red carpet for her to walk on, though she still has a child-like personality. She came because she missed her sister and addresses her sister by her middle name, Angelica. She sees her sister in high regards, saying she is ten times greater of a woman than she is. She is completely unaware of her sister's delinquent status and is the only person who likes the drinks Saya makes, going to her school solely for a cup.


 * Mj uto
 * Better known as Mito the Steel or King of Ibaraki. He is the gang leader of Ibaraki and always seen dressed up as a knight (hence his title) with metal pipes as armor and weapons, which he doesn't ever remove even when he is eating or in the summer heat, yet removed his helmet to give a heartfelt plea to Mary. He has a horse and normal fights while riding him, and cares for it as well, pleading for Saya not to kill his horse after he was defeated. Where Tadashi went to the roof to meet Saya for their usual lunch date Tadashi met Mito and seemingly became fast friends. He becomes supportive for Tadashi and his girlfriend, completely unaware that the girl is Saya. He can change his personality at will, being kind and friendly towards Tadashi but vicious towards Saya, in the same sentence. He returns after hearing that the Undefeated Demon Head Saya was defeated by Tadashi and came to give him a congratulations present, where through this he mistook Saki as Tadashi's girlfriend. He also once saved a foreign exchange student named Mary, who fell in love with him after, however he sees himself as too immature to go out with a girl, but tells her when he does he will go out with her. He is a very strong fighter, able to take on multiple people at a time and sense a person spying on them from behind a wall, but no where near as strong as Saya. He is against the Haou-Sou, where he tried to defeat them only to be taken out by Momo. He is also portrayed as a bit of an idiot, believing his horse was making cat sounds where it was coming from the opposite direction (though that could have been caused by his helmet) and constantly mistaking Saki as Tadashi's girlfriend (as do many other people). He is also displayed to be very tall, where he had to bend down to walk through a doorway.


 * Ego
 * Heir to the Taketori Financial Corporation whose company made its fortune through its multiuses for bamboo. He makes his first appearance claiming to be that he is the fiance to Saya, something she didn't know anything about, believing her father set it up. He has a bad habit of proposing to every girl he sees but a natural talent of wooing women, even Yuna (which she denies) and the ability to know what a woman would want (from giving Mitsuki a bear and Momo a rare bandanna even though he never met them before), only to be snapped out of it by the attacks of his assistant Misako (though he proposes marriage to her as well). He does not know who Saya is, referring to her by Angelica. But when he does, though first shocked by her delinquent attitude, kisses her on the cheek and wants to get married immediately. He finds men to be the "enemy". However, from that kiss Saya lost all meaning for life and went on a destructive rampage, only to be brought down when she saw Tadashi. He later returns as a student now living in a giant bamboo next the the school (where the inside looks like a mansion) in hopes of getting his fiance to marry him, though he still asks marriage to any girl he sees (most of the time he charms Yuna). However, when he got mad at Saya for beating him up he decided to be "honest" and stating that "Tadashi and Saya looked like a perfect couple", he lost the ability to "gaze into women's hearts" probably because of being "honest", where instead of flirting he insults women unconsciously through this "honesty". He believes he gains back the ability after he successfully flirted with a new character named Yumi, only for later it to be revealed that Yumi is actually a he of course still not knowing this he was still gone marry Yumi but when Yuna flips up the skirt and is shoked and tries to call off the wedding but is Yumi does not want to let him go and cancel it, yet states he was joking after. He is currently still in shock from this discovery but later revealed he was forced to marry Yumi after all, which he uses him as a chair. It is suggested in recent chapters that his company has gone bankrupt, as he Misako and Yumi have been evicted from their house and currently living in the student council office.


 * Misako
 * Assistant to Kenji and more serious of the two. She usually has to snap him out of his love struck attraction by assaulting him (through the use of ninja weapons like throwing stars to scythes). She and Saya appear to be the only girls that aren't affected by his charm. Though she doesn't appear to care very much for him, asking if she should leave first to an obviously beaten up Kenji. She seems to be enjoying the way that Kenji is after he lost his charm and how Yumi bosses him around, even videotaping it.


 * Yumi Suzune
 * Yuna's older brother, who is a cross dresser being mistaken ironically to be a girl. He really hates liars, saying he would tear out Kenji's throat if he broke their engagement, though it is unknown if he is gay or just enjoys acting like a girl. Though he looks very girly, he is actually much stronger than Yuna. He is still currently Kenji fiance with a wedding ring on his finger, however later calls it off stating he was just teasing, and he hates the student council president because he calls him male even though he calls himself female. He was the Student Council President, but after he started to give attention to Tadashi, both Saya and Saki spoke against it. He renounces the position after figuring out that his sister has a crush on the Student Council President, believing that would be more enjoyable to exploit. In chapter 50 it is revealed he has been living with Kenji after forcing him to marry him, but only using that position to boss him around and use him as a chair. He then divorces him so he could marry the Student Council President (where throughout the entire time the Student Council President was completely unaware of what was happening) as a way to get his sister to dress more girly like when they were younger. He later forces Kenji to remarry him.


 * Munabu
 * President of the Newspaper Club and friend of Tadashi. He is always looking for a good story and has vital information on others, like for the G.I. Group and Taketori Financial Corporation.


 * Terumi Houjou
 * She is No. 3 of the Piyouta fanclub along with Momo, being a part of the Piyouta 4 though the other two have yet been shown, as well as classmates of Tadashi. She tries to help Saki with her diet by getting her off chocolate and help get her legs thinner. She suspects Saki's sudden interest in her appearance is because she has feelings for someone (Tadashi).


 * Mary
 * An international exchange student from America. She is in love with Genjuurou Mito and follows him wherever he goes. Mito once rescued her from a "drunk villain" and misunderstood his speech for a confession of love. She wants them to wear matching clothes as proof of their relationship. Mito has not reciprocated her affections yet, as he feels he is still too immature to have a relationship.
