Since it’s anime theme

Are custom OC allowed?

Yeah ofc

Bet

He can’t have powers or anything, it has to be aligned to the anime’s lore. Your OC has to have passes final selection

Damn nvm then lol

The only way to have powers in that world is to be a demon

Amaya(Slayer AU, her OG is that she's a demon): *draws her sword* What do you want, demon?

Demon: *backs away, it stares up at her with wide terrified eyes* P-please don’t h-hurt me

???: you’ll be an easy demon to defeat

Demon: *looks up at them with wide frightened eyes* A-are y-you going t-to h-hurt m-me?

???: I can make it quick so you won’t feel it

Demon: I d-don’t w-want to d-die

???: *sigh* you have too, if I don’t kill you you will kill and eat innocent humans *draws sword*

Demon: *starts to run*

???: *quickly grabs the demon and throws them to the ground* where do you think your going

Demon: *stares into their eyes* P-please

???: I already told you if I let you live you will kill innocent people

Demon: Got you *??? Finds they can’t move*

???: w-what the hell

Demon: Blood demon art, body control

???: so your just here to trick people into not killing you and then you control there body and kill them

Demon: A mouse who attacks a cat is still a mouse

???: just unfreeze me and fight me

Demon: Why should I fight you? You are already defeated

???: *thinks no no this can’t be it* I- umm

Demon: I can make it quick so you don’t feel it

???: no I won’t expect defeat *starts to try and fight the blood art*

Demon: *makes them sit down*

???: *keeps a firm grip on his sword* LET ME GO

Demon: But then I would die

???: you deserve death your evil

Demon: If we switched places, would you let me go? Of course not

???: if I was a demon I would kill myself

Demon: Sure

???: *tries to swing his sword*

Demon: *makes him hold the sword to his neck*

???: *a single tear leaves his eye and he thinks I’m going to die to my own blade*

Demon: Hm, I’ll make you a deal, I get one of your limbs and then you have to leave me alone

???: NO WAY IM NOT LETTING A DEMON GET AWAY AND KILL INNOCENT PEOPLE

Demon: You will die then

???: your evil you know that YOUR EVIL

Demon: I just want to survive

???: yeah so do I and the only demon that is allowed to love is nezuko

Demon: What?

???: nezuko a demon slayers sister that was turned into a demon but resists the urge to hurt a human

Demon: If I don’t eat anything I’ll get violent

???: resist the urge and fight back *tries to pull the sword away from his neck*

Demon; *pushes it a little closer* I’ve tried that, doesn’t work

???: *tears start to form* please move the katana away from my neck

Demon: If I don’t kill you, you will kill me!

???: your suffering it will be setting you free

Demon: What makes you think I’m suffering

???: I- just let me go

Demon: *pushes the sword closer* Last chance, I’ll take one of your limbs and you leave me alone. Or you die

???: *starts breathing heavy and thinks no no there has to be another way* p-please don’t

Demon: Don’t feel like dying

???: neither do I *pulls sword*

Demon: Huh

???: was I not clear enough a demon slayers sister was turned into a demon but she’s not dangerous to humans so we’re not allowed to hurt her

Demon: Sounds boring

???: so you would rather kill innocent people then help them you are pure evil

Demon: Why should I help people? What have they ever done for me?

???: WHAT HAVE YOU DONE FOR THEM

Demon: Well nothing obviously

???: maybe if you didn’t kill them they would be nicer

Demon: I usually don’t, I offer everyone the same choice. I get one of their limbs and they get to go be free

???: that’s still not fair no ones going to ever trust you

Demon: Because someone would trust a demon -.-

???: most demon slayers trust nezuko and she’s a demon

Demon: I can’t survive otherwise

???: I knew I shouldn’t of ever trusted a demon

Demon: You kill animals all the time for food, how is this different?

???: because we need to kill animals to live and you don’t need to kill humans you only need to kill humans to regenerate

Demon: If I don’t kill humans I get violent

???: which is why you need to die *tries to use many different forms but none of them work*

Demon; Do you know what happens when a species multiplies out of control with no predators stopping then? The species consumes all of its resources and dies out

???: *eyes widen knowing what’s about to happen* but they can control it themselves

Demon: I suppose that would be demon slayers

???: Yeah so prey doesn’t fight back they run

Demon: Demons are necessary for human survival, because you have no other predators

???: yeah then who are your predators
