[@VitaVitaAR] I'm still not completely sure what I want the backstory of my character to look like but something among the lines of the child of a Red Demons member and maybe a researcher. As such, she has been expected to participate in the war since childhood and has prepared to do so. Even though she has never encountered a vampire herself, her environment groomed her to adopt extreme views and an intense dislike for vampires.

Let me know if that's doable :) 

For the weapons, if it's like in Owari no Seraph, can they have certain supernatural-ish abilities like summoning some demon to attack?
