"If I had one more chance... I wouldn't let any of you die."
After the final battle against Muzan, the world is finally free from demons. Giyuu Tomioka lives a peaceful life surrounded by friends...until his 25th birthday.
As he takes his last breath, he says goodbye to the world.
Yet moments later, he wakes up years in the past with memories of a future no one else remembers.
Armed with the knowledge of how everything went wrong, he vows to rewrite fate, save the people he once lost, and search for a way to break the curse of the Demon Slayer Mark.
Will a second chance be enough to save everyone, or will history find another way to repeat itself?
(I apologise for the bad cover, am not really good at arts but still wanted to try lol)
