Did Yishu Make It Home Today? [Demon Slayer Crossover]

This story has been abandoned. I left it here as a draft to look back on, but I've started a new story with the same title, yay! After taking part in the Holy Grail War, Uchiha Kazuki set off happily for home, bringing the Holy Grail and his Servant, his great-grandfather Senju Tobirama. Then their plane fell out of the sky, landing in a world full of wisteria flowers, where humans and demons were locked in constant battle. Some First Brother: The Transparent World... You're a child of God, too?! Kazuki: Huh? No, this is my Sharingan. Some scummy boss: You have such powerful healing abilities, and you can use your cells to affect other people... Could you be a demon, too?! A demon who can walk in the sunlight?! Kazuki: Huh??? No, this is Wood Release. And so, with help from a brilliant scientist, a Master who was both a child of God and a demon among men entered a fantastical tale set in the Taisho era. Theme: Even in the most desperate circumstances, keep hope in your heart, stand by what is right, and journey toward the light!
