Anime Crossover: The Breath of Evil in Demon Slayer

After transmigrating to the Demon Slayer world, Gu Bei finds himself from the start in the pleasure quarter, the liveliest place after dark.

This is territory ruled by Daki, one of the Twelve Kizuki.

Gu Bei originally planned to pay for a good time and leave.

Who knew he'd awaken the Devil Fruit System and master the Breath of Evil?

Eat the Flame-Flame Fruit and master the First Form of the Breath of Evil, Crossfire, and the Second Form, Great Flame Commandment: Flame Emperor.

Eat the Op-Op Fruit and master the Third Form of the Breath of Evil, Slaughterhouse, and the Fourth Form, Gamma Knife.

Eat the Fish-Fish Fruit, Mythical Zoan, Azure Dragon Model, and master the Fifth Form of the Breath of Evil, Recovery, and the Sixth Form, Mist Ascension.

Muzan: I suspect this guy is Yoriichi reincarnated.

Daki: That's too much! He got the services for free!

Nezuko: Lord Gu Bei, thank you for saving me.
