Question about an idea

before i even begin with my idea, i want to ask if i can even do it
i intendt to be a sort of warrior called Shadow Hunter , a sort of vampire hunter , under the service of an emperor in another world
if you allow me to work my idea i assure i will not go killing vampires or the sort, and i will keep to the canon, minus some modifications on my part
thats about it, if you allow me to play lke this i can go on detail about the character background, but i can assure i will follw your rules to the letter

pm Hayley williams she is sort of our boss until the owner comes back she is sort of second owner xD ask her she will tell what to do.
