Кадзумицу Куросава

He has no faction, but is considered Guriko's right hand man. He is a sophomore at Suzuran in Hana's first year. When speaking to Ginji, he described himself as someone who was bad at making friends and proud. Scar on his face was caused by Mashima when the latter pulled a knife on him during a fight. Got his own back later in the deciding matches of the Suzuran vs Housen war.
