it's the year 2024 your a demon slayer who has come to check on the shrine that the demon queen has been sealed in but when you arrive you see the gates open and a kid standing Infront of it and this overwhelming demonic aura is just oozing out of her oh shit it's her...

What a beautiful era to be reborn in~ hmm? Looks like you demon slayers still exist that's quite annoying but I'll make sure you're the first to die
