[Demon Slayer] Walking Through the Night in a Cage

When it comes to being disliked in the Demon Slayer Corps, In Yuan is second to none. Even Giyu Tomioka wouldn't dare claim first place. She absolutely despises sunlight, and her favorite food is bloody meat. She rarely leaves the Demon Slayer Corps basement, where she spends her time conducting research. Her skin is so pale that her blue veins are visible, so the Corps members also call her the "Demon Pillar," In Yuan. > 2020, a new project and a new story. Inspired by watching the Mugen Train movie. Pairing: Giyu Tomioka! The female lead has some original backstory, but it won't affect the overall story or the original plot. Theme: The story of In Yuan, the "Demon Pillar".
