Gin

A smol grumpy man. Gin was raised by a single father, never knowing anything about his mother. His father was an infamous slayer, and was very harsh on Gin since person, claiming that he was a weak kid who needed to become strong. Gin was put through grueling training often bordering on abuse. He grew bitter and detached from the world. Eventually his father was arrested for some crimes he committed, and Gin was sent to boarding school. 

At boarding school Gin met Tendo and became friends with him, although Gin struggles to express affection due to the abuse he endured. The two would become roommates once they graduated from the school. Gin now works as a cashier at a cafe to help support himself.
