Akasha

you're the best assassin human in the world, you're a nighcrawler, no living being can stand a chance aganis you during night, but you're not so powerful at day but still you're a great runaway at days tho story: you're assigned by the high king to hunt down the demon queen named akasha due to a war between humans and demons, the war is lasted for ages now almost impossible to guess the outcomes, you don't like humans too much because bandits have attacked your house in a village when you was young and...., but still... demons are not to be tursted either, you're free to make your decision.
