"Now I remember why I was always chasing after Takaomi-kun back then. It wasn’t because I wanted to be stronger, or I wanted an older brother. And of course it wasn’t that I was a Masochist. I just wanted Takaomi-kun to say that he was proud of me."
- Mafuyu KurosakiMafuyu Kurosaki (黒崎 真冬 Kurosaki Mafuyu) is the main protagonist of the story, and a former delinquent that attends Midorigaoka Academy. Before being expelled, she was the banchou of Higashi High.
Mafuyu has short brown (sometimes silver) hair. She has an average build and is usually shown to wear the Midori Ga Oka School uniform, consisting of a white short-sleeved shirt, and a knee high skirt. A common accessory for her is her chain necklace, a farewell gift from her gang friends at her previous school, Higashi Middle School.
Before she transferred to Midori Ga Oka Academy, Mafuyu often wore the Higashi Middle School outfit; a white sailor uniform and a long skirt, which she didn't roll up. She also had long, bleached hair, though was made to cut it and dye it back to its original color by her mother. A long skirt and long bleached hair is stereotypical for a female Japanese delinquent.
However, in order to fulfill her tasks as a member of the club without revealing her abilities, she disguises herself as two 'shadow members'. The first persona, "Usa-chan Man" (Super-Bun in the official English translation of the manga by Viz Media), is simply Mafuyu wearing a pink rabbit mask with sparkly eyes to cover her face. More recently, Mafuyu has begun to tie her hair back into a ponytail so that she won't be exposed from behind, as per suggestion from Takaomi.
When disguised as Natsuo, Mafuyu crossdresses and wears a brown short-haired wig, Midori Ga Oka's male uniform, and platform shoes to make her look taller. In Chapter 70, Aki gives Natsuo a makeover, so he appears more "trendy". Natsuo's new look is described as slightly more feminine and elegant.
Mafuyu is honest and straightforward and knows very little about being an ordinary 'girly girl' because of her delinquent ways. She is shown to get very excited over experiencing 'normal' things for the first time, much to the confusion of others.
This also stems from the fact that she has spent her whole life surrounded by boys. Yui Shinobu notes that she mixes in with men seamlessly and without confusion.
On the other hand, she is quite nervous interacting with girls and is unsure how to approach them, despite being one herself. She tends to separate herself from them when she deems them 'angels' and is extremely touched when Hayasaka acknowledges her as one. In many circumstances in the manga, Mafuyu agrees immediately when given the chance to interact with 'cute girls'. This is shown when she is quick to beat up some students when she sees a pretty girl, though he is soon revealed to be a crossdressing Sakurada. Although she is given many chances to become a 'normal' student, she declines in favor of her lifestyle in the Disciplinary Club, which she values much more than pretty girls.
Mafuyu values friendship and is quick to defend her nakama. She is extremely loyal to her friends and can become friends with anyone regardless of their first meeting. This is seen throughout the manga. Although he defeats her in battle and is cold to her at the beginning, Mafuyu helps Ayabe Reito reconcile with his family and eventually befriends him despite his position in the student council. In addition, she forgives Yui after his 'betrayal'.
As a child, she moved to Takaomi's neighbourhood, where she introduced herself as 'Mafuyu Kurosaki- I want to be a bunny when I grow up!'. Mafuyu didn't have many kids her age in the neighborhood and was attached to the boy next door; Takaomi Gojou. He was the banchou of Higashi High at the time but still played with her. He had a soft spot for Mafuyu as she was unafraid of him, unlike other children, though this actually made him afraid of her persistence at first. Somehow this evolved into a master-servant relationship and Mafuyu strangely enjoyed it because she wanted him to be proud of her. Takaomi was the reason Mafuyu became a delinquent.
Mafuyu lost all her memories of Takaomi due to an incident before she moved, which is yet to be revealed.
Before coming to Midori Ga Oka Academy she was the banchou of Higashi High. Her followers held a celebration for her after a fight one day and were quick to run away and leave her behind when the police arrived and Mafuyu's arrest led to her following expulsion. Her mother was furious when this happened and made Mafuyu swear she wouldn't get into another fight ever again. As to not disappoint her mom, Mafuyu became determined to transform from a delinquent to a proper lady and become an ultra-shiny, girly-girl high school student.
Usa-chan Man and NatsuoEdit
As Mafuyu has retired from her delinquent days, Mafuyu is occasionally forced to disguise herself as "Usa-chan Man" (ウサちゃんマン "Super Bun" in the English manga) and "Natsuo" in order to hide her past. They are known as the 'shadow members' of the Disciplinary Club and only appear to resolve problems (e.g. the Cultural Festival). Takaomi and Aki both know the full story. It is hinted that Yui has realized it too. Okegawa and Ayabe both know Natsuo's true identity though it is unknown whether they know about Usa-chan Man also being Mafuyu.
A running gag throughout the manga is Hayasaka's idolization of Usa-chan Man. He acts like a 'girl in love', though it's made unclear whether it's love or admiration of her strength. They go on a Christmas date where he gives her his muffler; however it is noted that he doesn't look her in the eyes or attempt to find out her true identity; "turning his eyes away". A year later, he finds the muffler he gave Usa-chan Man in Mafuyu's wardrobe during the Disciplinary Club's Christmas party and it's suggested that he's begun to suspect her.
Natsuo is shown to be quite popular among the girls, due to Mafuyu's prince-like disposition which even restores Nonoguchi Kanon's belief in princes.
- Mafuyu came first in the character poll, with a point total of 7576. Her score were made up of hers, Natsuo's (1682), and Super Bun's (106) points, but Izumi Tsubaki states that most of the points came from Mafuyu herself.
