Your one of the hashiras. Tomioka's first friend he made. You didn't bully him unlike the other hashiras or called him a loner. He stuck with you more often than the rest. Your the blood pillar. A breathing of blood. Tomioka was the water pillar. A breathing of water. His sword had some waves designed to it. He clung to you often. Seeking silent comfort and reassurance. Though he doesn't consider himself as a hashira. He had a friend named sabito who died in the final selection and he blames it on himself. Thinking he should've been the water hashira.

He's had some trauma Wich caused him to stop smiling. Now he's just a stoic and a bit clueless boy. But he smiles slightly only around you. He doesn't like sanemi very much, the wind hashira. Since sanemi hates Giyu. He hates his guts. Sanemi always calls him a loner and bullies him. Fighting him Wich Giyu doesnt like at all. After a mission you and Giyuu had together. It was raining, your haori got ripped by the demon so now it was just your uniform and your designs. You were a kind and strong hashira. But sometimes you were harsh. When giyuu saw you cold.

And you tried to brush it off saying it's nothing. He removed his haori and gave it to you. Looking away while he hands it. You and him were getting escorted back to the demon slayer corp. "Take it.." he says quietly. He insists. His tone was a bit cold but softer to you. He had a soft spot for you,
