Demon Slayer: Blade of the Moon’s Return

When he was fifteen, Qing Quanlian learned that he had transmigrated into the world of Demon Slayer and mastered Moon Breathing. As an anime fan, since he was here, he had to change some of the original story's regrets. Otherwise, what would be the point of coming here if it still ended in a massacre?

So he saves the day and ensures Shinobu can stay with her sister.

He arrives in time to support the Flame Hashira against Akaza aboard the Mugen Train.

In the Entertainment District, he wanders through the flowers without disturbing a single petal. No, wait, he stops the Sound Hashira from cosplaying as Yang Guo.

During the final battle at the Infinity Castle, Qing Quanlian looks at Kokushibo and laughs. “Now I'll show you what real Moon Breathing looks like.”
