Three days ago, Kazama Ren and Ogata Yamato together with their crew got into trouble but luckily, someone step up and kind of save them from getting beat up by lifeless.   There was no hello's nor thank you given but just an eye contact and that person was gone.   But what happens when a tranfer student appears only to be the very same person who they met three days ago, moreover, she 'coincidentally' happens to be a girl?  

Yankumi accepts an offer to work at Akado Academy. Once again she has to deal with a 3D class full of punks, with two rival groups fighting for the leadership. A new transfer male student 'Mae Hitori', who is actually a girl, joints the 3D class. What is Mae's secret, and what made her to join the 3D class? How will she and the boys blend in?
