Lookin for something where mc was human but then has a racial change to something that is seen as an enemy of humans like a demon or vampire, etc. Can be either reincarnated, sudden change out of nowhere, system, summon, etc. I wanna see - mc attempt to fight urges to attack humans, like vampire attacking humans for blood, etc. - hiding his identity from others - can be either instant OP or strong over time Umm Also looking for some really badass dark/evil mc that does whtever they want. - fantasy setting with powers Thats all. Kinda broad, but got really want something to read.
A Monster Who Levels Up, Demon king (toika), Stop! Friendly fire (comedy, humans are introduced much later) Death Mage who doesn't want a fourth time(not much resisting the urge to attack humans, for good reasons),
Golden Fox with System <- MC reincarnates as a red fox, OP, really does whatever he wants and basically a living devil for his foes... the only thing missing the urge to attack humans, there are issues between races, but it's subtle because the starting island's population mostly demihuman/magic animal ect...
