-Tyranny-
Dropped in the Demon Slayer verse, our protagonist, Zelda, finds herself stranded in an unfamiliar world. With a famous, overpowered sword and an even more overpowered body. Zelda is basically Link, but female and she has the same name as the princess of Hyrule. She does have a secret, she is originally from Earth. She knows about the Demon Slayer verse but she hasn't watched much of it. She is however a big fan of The Legend of Zelda.
The moment she is dropped in the verse, she is given two roulette wheels, one gives her a weapon to use. Through this she gets the Master Sword. Another gives her a passive ability, the Triforce. Through the Triforce, Zelda gains overwhelming physical capabilities, limitless courage, meaning Zelda is never afraid, and the ability use 'divine' energy. This divine energy completely destroys demons on a cellular level.
