Vulgar Spirit Monophobia

High school student Houdzuki Maika is never truly alone. Her twin brother, Maito, who did not survive birth, exists within her, sharing her body and alternating control with her each day. While they share most of their memories, the siblings can only see and speak to one another in the shared dreamscape of their sleep. This unique supernatural bond has granted them both the ability to perceive ghosts, setting the stage for a series of mysterious and unsettling encounters as these inseparable twins navigate a world unseen by others.
