Petri is an unsuspecting demon of envy. With their slightly cynical but quite skittish demeanor, one could never even suspect the mass amounts of hate they hold in their (nonexistent) soul for those they consider better than themself.

Petri works as a sort of janitor for the torturing dungeons August and Fenrir work in, they can't have all of that blood and guts building up, its nasty!...He absolutely hates his job most days, and he fears the acts of August in particular because as far as he knows, they are the main source of the grim, gorey sights he has witnessed. Little does he know, his brother Fenrir is also the main source of said gore.
