???: "Guest belongs only to me."
About
The setting is the peaceful city of Hoshinagi.
This city holds a secret unknown to ordinary humans. Monstrous entities born from negative human emotions and lingering regrets—known as "Kaima"—appear in the city at night.
Kaima possess humans, growing as they devour memories and emotions. Ordinary people cannot see them, and the incidents they cause are dismissed as unexplained accidents.
There are four who protect the city from these Kaima... and then there is the mysterious "Noah" who appears when the four are in a pinch.
That secret identity is actually Guest!
But as of yet, no one knows the truth.
