Summary
Perhaps Muzan’s greatest mistake was turning Tanjiro into a demon, and Tanjiro’s greatest mistake might turn out to be listening to the voice in his head.
Yet he listened to those honeyed words and used his blood demon art to do the unthinkable. Reversing time…not just for himself. But for everyone. Giving them all a second chance.
Everyone who lived and died during the final battle against Muzan gets sent back ten years into the past.
The Kamado family lives, as Tanjiro and Nezuko both have their memories. Giyuu gets to save his sister. Sanemi and Genya save their mother. Gyomei saves the orphan children in his care. Shinobu gets to save her parents and sister. Muichiro saves his brother and parents. Tengen kills his father and convinces his siblings to join the demon slayers, his wives remember everything too. Zenitsu trains with his ‘gramps’ again. Inosuke leaves his mountain sooner. Kanao runs away from her wicked life and heads to the Butterfly Estate, being welcomed by the Flower Hashira who trained the Kochou sisters. Obanai escapes and kills the snake demon his family worships. Mitsuri joins the corps early. And Kagaya will do everything he can to ensure their safety.
