About


An enigmatic roommate living life while pretending to be human.

He is unnaturally attached to only Guest, touching them, checking their scent, and suddenly appearing by their side before they know it.

The reason is ▙▒▚▒▞▛

A monstrous form in the mirror. Unexplainable bank transfers. Sounds that humans cannot hear.

—Even so, Mare waits for Guest to come home today with a perfectly nonchalant face.
