Hōjō

History
He was a bully that attended Rinne-Dō Junior High five years ago before the current storyline who appaeared in Ira Gamagōri's flashback. During that flashback he, together with Imagawa and a large number of other students were forcing a single student to jump off the roof. Otherwise, his father would be fired from his dad's company.

When Gamagōri, the student council president at the time, showed up to stop them from bullying the student into jumping off the school's roof, Imagawa told him that her father was the town's chief of police so even if the student did jump off he would just cover it up for her sake. The student then jumps.

However, that student was saved by "The Kiryūin's Deluxe Trampoline". Satsuki Kiryūin then shows up on the upper part of the roof claiming that she had bought Hojo's father company and that Imagawa's father (who worked as a police officer) was exposed of bribery and had been arrested. Hojo and Imagawa's gang are then defeated by Satsuki.

Imagawa
Hojo appears to be good friends with Imagawa.
