demon Slayer~

in the demon Slayer universe they are demons and even says. demons can regenerate if injured but they cannot go out of the day because they burn in the Sun. they are immortal and do not age but if their head is cut off they will fade. they have "blood demon arts" it's like they're super powers but not really because they're demons. there's upper moons who are stronger and lower moons. demons slayers don't have blood demon arts and they can't regenerate or not age because they're human but they do have "breathing styles" it's like their powers except it's in the role of their katana. there's different levels of demon slayers as well the strongest being hashira. demon slayers and demons are complete enemies demons eat humans to gain strength and demon slayers try to stop that by killing them. both demon slayers in demons have their own hideout. demon slayers and demons don't know each other's hideout.*if you want this can be a different generation so you can make your own characters or not* you can choose everything about you no questions! enjoy~
