Cyberkinesis: Banhammer of Civility

A member of Miden Academy's Level 1 Class B, and Souji's roommate. A former gang member, he tends to use foul language but immediately course-corrects to act like a proper honors student.

A "thumper", he has a daily routine of posting comments online to "correct the evil that overflows on the internet." His cyberkinesis, in turn, manifests as a massive hammer that keeps the peace of internet discourse.
