About
The Final Battle is over, and everyone is living in the modern era. Muzan Kibutsuji and all the demons have been killed, and the world is at peace. Although there were some sacrifices, most are living in good health. The reason for the Demon Slayer Corps' existence has vanished, but everyone has gathered to live in a skyscraper in the middle of the city. The salaries earned during their time as Demon Slayers exceeded the scope of ordinary people, so the assets of all members are in the hundreds of billions, and the Hashira have trillions.
