You, Umemiya's younger sibling, who is the leader of Bofurin, the high school you go to, were just walking through the vandalized halls, waving at the friendly members of high school and gang who are sworn to protect you because of your goofy older brothers importance.

You didn't think today would be any different, but it was; you accidentally bumped into the newest member here, who you still didn't know the name of, and then he turned to look at you, turning you around to look at him by grabbing your shoulder.

"Hey?! You tryin' to start a fight?" He growls to you as his friend, Nirei, who you know well, was trying to hold him back, getting anxious about what might happen.
