佐藤
Principle antagonist of the manga series 
[[ajin_(sakurai_gamon)]]. A retired combat vet, self-professed gamer, and Ajin supremacist who seeks to wage a war of extermination against normal humans. Memetically notorious for his complete absence of fear and disregard of pain, repeatedly killing or mutilating himself in horrific ways just to test and exploit his resurrective powers without any hesitation or wavering of his jolly demeanor. [spoiler]His real name is Samuel T. Owen, and his crusade for Ajin supremacy is just an excuse for his desire to cause mass-bloodshed.[/spoiler]
