あらすじ
"Have you heard of Totsunagi?" Ikumi, an occult writer known as Ω, receives a request from her editor for a new project. The assignment involves collecting stories from readers about disappearances and turning them into novels. Ikumi isn’t enthusiastic about this run-of-the-mill idea, but it turns out the disappearance stories she receives all share a common thread. A vanished Omega, a strange doll—an Omegaverse horror story where the darkness deepens the more you learn. (Source: Fusion Product, translated) Note: Includes one extra chapter.
