(Based on the Anime "Seraph of the End".)
Make sure to check the bio once in a while. I'ma make changes here and there.
A virus has spread across the world, wiping out about 90% of the human race. You are a vampire exterminator, killing vampires that rule the world now. Or you are a vampire, sucking up delicious blood and killing the humans, while ruling the world. Or you are a demon... Um... possessing people I guess?
(Note that I am not far into the series... :P)
Name // Age // Gender // Human or vampire or demon (There's probably more races but like I said, I'm not that far into the series...) // Personality // Look // Outfit (You know, like the vampire exterminator outfits, or vampire outfits, if you aren't a human or a vampire, you won't be wearing outfits so you can put what you wear for look) // Crush / BF / GF // Weapon // (If you are a vampire exterminator, please do the rest of this bio, if not, don't continue) Demon's Name (Well, you should have a cursed weapon so...) // Demon's Look // Relationship with the demon
(If there's stuff I should add, let me know in the comments.)
