Summary
Despite his intimidating, delinquent appearance, Katai is actually a nervous and awkward individual who often stumbles over his words. His primary goal is to overcome his social ineptitude and make friends. Tadano quickly sees through his false tough exterior and becomes one of Katai’s closest friends. Once a lanky boy, Katai’s physique has transformed through exercise into something sturdy and delinquent-like. He regards Komi as his "master" and believes she is constantly encouraging him to improve his friendship with Tadano.
