Hinako Nakayama is an orphan and a martial arts expert, who was living her life in a fuzzy haze when she finds herself attending a new school. While the new outlook she gets from her new surroundings is great, there's a few problems: 1) Its an all-boys school 2) Its student body is nearly 100% punks who are ready to brawl at a moment's notice and 3) She's attending under an assumed identity that ensures the toughest are all going to be gunning for her!

Hinako is now cross-dressing in order to attend the extremely roughneck Shishiku Academy as Hikaru Onigashima. How exactly did she get into this mess?

Hinako reaches the next hurdle in her quest to take over Shishiku Academy: Takayuki Konparu. The only problem? The steely first-year has no interest in fighting her!

Konparu has sent a letter of challenge to Hinako and is now out for her blood. Why is he suddenly ready to fight her? And can Hinako win the fight when she learns the truth?

With her control over the first-years secured Konparu and Totomaru head to Hinako's house for a study session to prepare for mid-terms.

One of the two top second-years, Yuta Mirako, is both an idol and a brawler. An upcoming concert at Shishiku Academy brings him into conflict with Hinako.

Mirako's disgust at the concept of friendship has Hinako curious, and after hearing about his troubled past from Kira, she decides to help him.

The other top second-year student, Rintarou Kira, seems to know Hinako's real identity. How does he know, and what will it mean for her conquest of Shishiku Academy?

Hinako is unsure what to do now that she remembers who Kira is. Will Hinako continue her attempt to take the school over?

Kira seems to know who Hinako really is, and wants her to give up her conquest of the school. It seems the only way for her to convince him otherwise is to fight him... and win.

Rumors are starting to spread about Hinako's true identity, and if something isn't done soon to quiet them, she risks her own school turning against her. Luckily, she can still rely on her friends.

When Hinako Nakayama took on the identity of Hikaru Onigashima, she didn't know what it would mean for her future. Now, with the support of the friends she's made with her martial arts skills, it's time to prove who's the boss of Shishiku Academy!
