Kaiya was lost in the darkness of Yokai Realm. She met the Trio: Kenka the Samurai-Ghost, Warai the Hyottoko and Hakai the Namahage.
They asked her to stay and wait for her brother, in the meantime, she could be their ally. Kaiya then befriended with the Trio and all of the queer Yokai there.
They seemed to be good guys, Kaiya thought.
