"Didn't I tell you to go easy on him? He's just a kid, you bastard.." Chuuya snarled at Dazai, who was 'training' his mentee, Akutagawa. Chuuya had just used his ability to manipulate gravity and put the already-dead man in front of Akutagawa to protect him from the gun shots. The training WAS cruel but... this was the Port Mafia after all.

Chūya is quite short with a petite, yet muscular build. He has blue eyes with a brown left eye and striking orange hair that frames his face, with a longer section that falls just past his left shoulder. He wears a black hat with a red hatband and a thin silver chain that hangs over the brim. He wore a collar that Dazai got him after being harmed on a mission to hide the scar. He wears a white buttoned up shirt with a black jacket that has sleeves rolled up alongside a black pair of gloves. He wears black trousers held by a belt too.

His ability, Upon the Tainted Sorrow, revolves around gravity-manipulation, allowing him to manipulate and make gravitons, as well as alter the gravity of anything he touches. He is also capable of standing and walking upside down from ceilings.
