Daichi Shinagawa was just a Yankee (Japanese term for delinquent) who wanted nothing to do with his high school life. Hana Adachi, the dedicated class representative, however would not allow it and constantly bothers him to be involved in school life. Shinagawa is first confused on why does she keep pestering him until he discovers her secret.
While she may look like a typical class representative stereotype, Adachi is actually not very smart and lacks common sense, and Shinagawa eventually learns that Adachi is a former delinquent. Regretting being a yankee during her middle school years, Adachi decides to change her ways to achieve her dream of becoming the best class representative. She decides to help Shinagawa so he will not continue to make the same mistake that she did. Thus begins the adventures of these two unlikely friends and their classmates.
Mon Shiro High School Student Council
- Daichi Shinagawa (品川 大地 Shinagawa Daichi?)
- The male protagonist of the story and known as "Yankee-kun," Shinagawa is a short-tempered delinquent who does not like to be bothered and has no plans for his high school life until he meets Adachi. At first he is constantly annoyed about her repeated attempts at making him come on a school field trip until he learns about her past and her resolution to become a class representative. He changes drastically throughout the series, from major things such as becoming Co Vice President of his class, to small things such as not smoking and avoiding class in his bathroom stall. He is also an honorable person who will try everything to protect others. His best subject is math.
- He has a love-hate relationship with Hana Adachi, liking her due to her nature to help others no matter what, but becoming annoyed with her due to her idiocy, lack of common sense, and forcing him to help with her bizarre plans and antics. He suspects that she is constantly with him because she likes him, but whenever he asks her about it, she ignores the question or acts ignorant on the subject. In the bonus chapter after 53, It was shown that Shinagawa decided to attend Mon Shiro only after seeing a beautiful girl at his entry exam (confirmed in chapter 61 to be Hana without her glasses and loose hair). Chiba, Izumi, and Akita were also presented. Shinagawa, although he always bicker with Hana, would do anything so that he won't hurt or upset her. Like, not telling her who he likes (which is obviously her, without glasses and with loose hair). At the end he admits he likes Hana Adachi.
- In chapter 150, his past, before he became a delinquent, is revealed. At the time, due to innate talent and his being very hard working, he was one of the top students in Daishi Chugaku (大紫中学), a reputable private school, where his number one rival (in studies) at the time was a girl by the name of Hachioji Shizuku (八王子 雫). Upon realizing that delinquents were interfering with her ability to study, Shinagawa became directly involved to save her, resulting in his expulsion and his eventual lost of interest in studies. This event also marks his becoming a delinquent and when he got his current hairstyle.
- Shinagawa's household background is also revealed to be other than what one expects. His father is a doctor and his mother is a lawyer.
- Hana Adachi (足立 花 Adachi Hana?)
- The female protagonist of the story. Adachi is the class representative, and later, the student council president, who always hangs out with the delinquent Shinagawa. While she may appear to be the dutiful, respectful, and bespectacled class representative, there is more to her then meets the eye. In reality, she is a poor student, not very smart, absent-minded, oblivious and clueless in present situations, lacks common sense, and actually has great eyesight (her glasses do not provide any eye correction). She always forgets things easily like who's she's met before and stuff. Her strength and fighting skills left over from being a former delinquent overshadow these aspects. She lives with her weird grandmother.
- Her past is a mystery, other than that she was fearsome delinquent in middle school. Even the mention of her name was enough to inspire fear in anyone. She is even able to influence a group of Yakuza gangsters to release Shinagawa and Nerima. She enjoys blaming Shinagawa for everything. Later chapters past 100, Hana turns out to have a younger sister,Subaru Mito in their rival Aaosuji Academy who has short hair, no glasses, no mole under her left eye and who is two years younger than Hana. Like Hana, her younger sister also appears to have a thing for Shinagawa, choosing to cut her hair to make herself look different from her older sister. Her brother also ran away from home to be with her like Rinka, but was told by Hana to live with Shinagawa instead. He's a genius who pretends to be a yankee.
- Seiya Chiba (千葉 星矢 Chiba Seiya?)
- A tall, bespectacled, fearsome-looking student with noticeable scar extending across his forehead and left eyebrow. When first introduced, he became a hikikomori a week after he got into trouble with a gang. Adachi and Shinigawa beat the gang (without knowing they themselves were the cause of his self-isolation) which allows him overcome his fears. When they forget about him, he is shattered again. Adachi tries to get him to attend school and take the exams, but he refuses, saying he is afraid of sitting next to Shinagawa. But Shinagawa realizes that Chiba is merely looking for Adachi's attention, and tells him to attend school and take the exams or she will never visit him again. Chiba is very smart and rich, and his mother is young and beautiful. He has a habit of unknowingly glaring at people which often cause a misunderstanding. He is very smart and almost always scores 100 marks for his tests, except for one occasion in chapter 67, where it is shown that he scored 94 marks on a math test, 2 marks lower than Shinagawa.In later latest chapters, it is shown that he has a crush on Makoto which seems obvious to everyone around him, however Makoto doesn't seem to have noticed yet.
- Rinka Himeji (姫路 凜風 Himeji Rinka?)
- Adachi's kohai from middle school who transfers to Adachi's high school in Volume 3, Chapter 23. Known as "The Bloody Pantheress", she was a Yankee and Hana's right hand man back in middle school. She is still very devoted to Adachi, and has been ever since Adachi saved her and they became friends. While Adachi has reformed herself to become a good student, Himeji on the other hand still acts like a delinquent and believes that Chiba and Shinagawa are her subordinates. She has a bad relationship with her family because she is adopted, and when she told them that she wanted to move to Adachi's school, they kicked her out of their home. Adachi took her to live at her house after finding out about it, after Himeji had spent a night sleeping in Shinagawa's bed. In chapter 56 she is shown to have a crush on Shinagawa. Like Hana, she has very strange way of thinking.
- Gaku Izumi (和泉 岳 Izumi Gaku?)
- Student council Vice President along with Shinagawa. The two often fight over being the better Vice President. He is very good at fighting, even being able to block Adachi's kick, but he cannot beat Adachi in a fight. He is also good at studying (his grades are second in the entire grade) and he gets really hyped up over the smallest things. He used to be in a motor cycle gang and still loves to wear his old gang outfit. He is close friends with Kagawa.
