[Demon Slayer] When I Became Makomo

Fu Yu transmigrates again.

This time, she transmigrates into the world of Demon Slayer. But she knows nothing about the plot and has only watched the first episode of the anime, while the little-girl System that brought her here is trembling in fear...

Fu Yu, however, says there's no need to panic. She's a divine sovereign from the highest realm of the gods. This is only a tiny world of anime, and she's already been through so many little worlds...

And so she sets out on the path of killing demons.

When she sees all kinds of bizarre-looking demons, Fu Yu covers her eyes and says, "Nope, too ugly!" She complains about how hideous they are while chopping off their heads.

Demon: Is being ugly my fault?

Until she meets Muzan. Fu Yu looks him up and down, then covers her nose. "You're not too bad to look at, but you stink!"

Muzan: ...I want to kill someone.

Fu Yu: Then you should go to hell first.

In short: This is the story of someone who is already ridiculously overpowered, but has to reluctantly rein in her brilliance. She grumbles about how ugly the demons are as she kills them, and saves the world along the way.

P.S. The heroine transmigrates into Makomo, two years older than Sabito and Giyu. Several characters will have unrequited feelings for her, and she's a bit of a sucker for good looks.

Theme: The world may be cruel, but always keep hope in your heart.
