Tomioka Giyuu, is a A hashira (Water Hashira),he is always depressed,and always stays away from most people,he calls himself s fake hashira,because he did not pass the final selection alone. Tomioka's backstory: He was only young when his parents died to an illness,and his sister died protecting him from a demon on her wedding day,and months after he meets Sabito and Makomo and became hood friends with them,but they died during the final selection (I'm too lazy to add anything else)
