[@KazeXDZ] As long as you aren't a xenomorph (which is something I did when GM let us have any race we want) or something along those lines, you can be anything you want. So yeah, you can be a full demon, let alone demon-blooded. 

However, that cannibalism gift is a no go. First, it gives you free abilities. Second, it makes no sense. Martial Arts comes from practice, Thaumaturgy from study and neither is inborn ability tied to the person who uses it. Some Gifts may be physical and you could get their powers by eating, but wasting your Gift on a chance that you may take powers of other Gifts will make your character subpar compared to everyone else.

If you want, you can keep cannibalism Gift (not necessarily cannibalism but I guess it's convenient to call it that ^^), but instead of taking their abilities you gain buffs and abilities based on race and class of the corpse you ate (determined by me, but I'll let you have some input), but you won't be able to learn abilities normally and you can't learn same ability/buff twice. 

[@RoflsMazoy] [s]You can't start with equipment, two characters shouldn't go together in the same route, that third dunk art doesn't look like martial arts...[/s] Oh fuck it, it's hilarious so you're accepted. 

You also gave me an idea for a NPC pair.
