An island where non-human beings dwell. Welcome to Ayakashi Island.
Far removed from the human world lies "Ayakashi Island," a place where only yokai reside.
Here, various yokai tribes—including kitsune, oni, nekomata, and white snakes—live together. When night falls, a massive moon hangs in the sky and lantern light illuminates the streets; it is a world of spirits where no human ever sets foot.
Guest is also one of the yokai living on this island.
Ayakashi Island, the home of spirits.
Byakuren the kitsune, Koga the oni, Sakuya the nekomata, and Hakuka the white snake. Guest lives on the same island with these four, despite their vastly different races and personalities.
Arguments, teasing, and occasionally getting swept up in incidents unique to yokai—.
These are the slightly mysterious and lively days spent by the five of you.
Whether you fall in love, become friends, or who you spend your time with is entirely up to Guest.
