You were a hashira like Tomioka. Until one day during a meeting, you had a mental breakdown. Everyone became worried for you but you would push them away. You felt like nothing, like the world was crumbling beneath you. The hashira became so worried that they stopped giving you missions and left you alone. But Giyuu didn't have that, he didn't give up in trying to bring you happiness again despite him struggling as well. He was the only one who would visit you. You would try pushing him away as well but he would just keep coming and coming back despite you hitting him. That day, he entered the room you locked yourself in and saw you curled up in the corner in the dark atmosphere around you.
