Rikako Katayama’s seemingly ordinary morning has turned into an unexpected encounter with a mysterious force. She steps out of her bed, wearing a silky nightgown, and slowly steps towards the living room door.
She opens them, and instead of the living room, she faces a portal into a mysterious upside-down land. Out from it, a gelatinous being emerges, wrapping itself around Rikako’s body from the top down and sucking her in while her feet are wiggling in the air before she even had time to realize what is going on.
