Nine

Nine is a young man with short, spiky blond hair and a scarred face. He wears a disheveled uniform of the Academy and wields a long spear.

He is impulsive and straightforward, viewing the world in black and white and only feels satisfied when things aren't complicated. Although he has a foul mouth, isn't exactly wise and is considered stupid by fellow classmate Queen, his courage boosts Class Zero's morale on the battlefield.
