Kazuki Mizuhara

Tomu's first ally and close friend who proves invaluable through several schemes. He is the class representative and first met Tomu when he was assigned to conduct Tomu's orientation. He is short, wears glasses and has a haircut which earns him the nickname "mushroom head". Although he has shown disapproval for some of Tomu's tricks and tactics, such as cutting one of his fingers off in order to seal Yuka's "magic", he has remained a steadfast reliable friend to the point that he has directly helped Tomu execute one of his tricks. He admires one of Tomu's trait of courage.
