Isaac Foster Husbando

Zack is the deuteragonist of the game, manga, and anime, Satsuriku no Tenshi. He first appears as an enemy of the B6 floor when meeting Rachel Gardner, and then becomes an ally over the course of the game. He is a serial killer who is currently on the run due to his connections with recent murder cases. Zack is impulsive and prone to violence. He is chaotic, quick to anger, and doesn't hesitate to use foul language in any given situation. When he gets the urge to kill, he becomes giddy and uncontrollably violent. He is barely able to control his murderous impulses. Zack has come into terms with being viewed as a monster due to his appearance and violent tendencies. While he has no problem with murder and destruction, he does see dishonesty as immoral, often declaring how much he hates lies.
