The Demon Slayer Plan Is Underway, and Everyone Survives

Characters may be out of character. ⚠ OOC warning ⚠ No CP in the main story ⚠️ Original plot and characters ⚠️ The main cast of the original work survives.

A Demon Slayer fanfic: a boy transmigrates into Demon Slayer with his unfinished Minecraft save and a System. Surely it can't be good for the System to stay inactive forever! Luckily, he eventually gets his cheat, and even though he's on his own, he can still do his best to change everyone's fate. He'll work hard to make it happen!

A lighthearted, sweet slice-of-life story. The entire original protagonist group survives, and there's no CP in the main story. There may be some Sanemi/Giyu and Doma/Kotoha (following the original storyline), but Sanemi and Giyu's relationship is brotherly. Feel free to read if you like that; if you don't, please take note and avoid it.

If you'd like to see them, I can write short CP stories as extras. The only pairings in the main story are Obanai/Mitsuri and Akaza/Koyuki! Any other pairings will be flagged at the beginning of the chapter, so read with care and avoid anything you don't like. I may write extras such as an alternate-universe story where Inosuke becomes the heir to the Paradise Faith, or one where Tanjiro becomes the Demon King.
