'I have underestimated the loyalty of one of my demons. I created one who I by accident made as strong and stronger than my first uppermoon. So now you would have two enemies Kagaya, so why don't we join side temporarily to end that being. I promise me and my demons, upper or common ranks will not kill any of your slayers-
The strongest phony demon, Yoriko, was underestimated by the demon king Muzan. Yoriko was unintentionally given too much blood by Muzan, which strengthened him and gave him the power to betray Muzan. Muzan was shocked by this, and not only that, Yoriko left with the power of creating additional demons.
The two demons now terrified the demon slayer Corp. the kings engaged in combat. Due to the fact that Kaito had now formed his own allies. Muzan was left with no alternative but to approach Hashira because neither he nor his uppermoons would be taken seriously by Yoriko's. Whose demon arts of blood were extremely strange and original.
The moment Muzan saw the Hashira of course no one trusted him, yet four people supported the idea. Kagaya, The Master of all demon slayers, Gyomei, the strongest Hashira and demon slayer. Muichiro, The young prodigy, and.... Giyuu, The third strongest Hashira, a feminine looking, cold and mysterious boy. Who incredibly caught Muzan's interest, reminding him of someone, yet he doesn't know who was he being reminded of.
This story has nothing to do with Blue Spider Lily's favorite demon!
The characters are not mine, aside from Yoriko Kaneki and his uppermoons!
