Battle with the Upper Ranks: Tanjiro and the Hashira engage in life-or-death battles with the Upper Rank demons, fighting to the end despite the pain of losing comrades. Final Showdown with Muzan: After a battle that lasts all night, the Demon Slayers succeed in dragging Muzan into the sunlight and defeating him. Tanjiro's Demonization: Muzan's blood and will are passed to Tanjiro, turning him into a demon, but he returns to human form with the help of his friends. Disbandment of the Demon Slayer Corps: With Muzan gone, the era of demons ends, and the surviving members welcome a life of peace. Final Farewell: The deaths of the sacrificed comrades cannot be undone, but their will and bonds remain in the hearts of those who survived. After Reincarnation Demons are completely gone, and they live in the modern era. Ordinarily. Only Sanemi, Obanai, and Giyu have become younger, while the others have aged by one year, with a few exceptions. Therefore, except for Sanemi, Obanai, and Giyu, everyone is tall. It is evident that only these three are short. Giyu, Sanemi, and Obanai's age before reincarnation: 21 years old. Age after reincarnation: 12 years old. These three were originally older than Mitsuri, Genya, and Tanjiro.
