Tatsu
CharacterDuring the Amusement Park Arc, a grey-haired killer named Tatsu turns up as a lesser villain. Working for Dondenkai, he fights with icy detachment, leaning on toxins and thrown blades; by blanking his mind he can even glide past Shin's clairvoyant senses undetected.
Appearance
Lean and tall, this young assassin sports spiky grey hair alongside ring-shaped earrings in black. Pale pupils light his sunken, dark eyes, and navy arrow marks angle downward just below them, which the manga renders as shadowy eyebags. His outfit is a dark purple polo with matching pants and black footwear. A line of stitches loops his neck before trailing down his chest.
Personality
Indifference defines him. He rambles on about appeal and shrugs off almost everything, never treating even a deadly brawl as anything serious. That composure stayed rock-steady when Shin tried to end his life aboard a roller coaster.

Abilities
His full arsenal stays unknown, yet a clear gift for poisons stands out: one nameless substance he used both wounded Shin and blinded him briefly. He can also evade Shin's clairvoyance by clearing his mind of any intent to kill, or any thought at all, drifting past unnoticed. Hurled knives are his signature tool, and he shoots pistols capably too.
