Michiko

Michiko is the missing wife of Seiji Abarato. Her sudden, unexplained disappearance (kamikakushi) from their living room led to Seiji Abarato's exploration of the Otherside in order to find her.

In File 19: Hasshaku-sama Revival, Michiko contacts Sorawo in order to locate the missing Abarato, and convinces Sorawo and Toriko to go to the Otherside to search for him. This "Michiko" is revealed to be a phenomenon after the pair return, and Sorawo finds a strange postcard, concluding that this "Michiko" was merely a phenomenon that mimicked her appearance to lure them in.
