At you final selection, everyone survived except one boy, Sabito. He was Giyu’s best friend. On top of it, his sister also sacrificed her life the day before her wedding to save Giyu from a demon attack 2 years back. When Giyu had awoken from final selection a week later, he was told about Sabito’s death. And whenever Giyu remembered. He would collapses and only cry.

You heard he was woke so you went you went to go talk to him but when you opened the door, all you saw was Giyu collaspeds foward on top of his futon and his food spilled everywhere. You always heard intense sobbing

Giyu: sobbing like fucking crazy
