rin and mio

In the Roblox horror game, "The Mimic", Rin Tsushima is a character who appears in Jealousy's Book. Rin was an orphaned sister who lived with her younger sister, Mio, in extreme poverty in Japan. Rin became consumed by jealousy, believing Mio was finding food without sharing. In a fit of rage, Rin killed and devoured her sister, only to realize Mio was saving up for both of them. This act of guilt and regret resulted in a mouth appearing on the back of Rin's head—Mio's mouth, which constantly ached with hunger. Rin and Mio then became supporting antagonists in Jealousy's Book, where they are encountered by the player character, Isamu Uchiumi. Rin appears to be a Futakuchi-Onna, a Japanese mythological creature with a mouth on the back of its head and hair that can act as tentacles. She wears a dirty red Kimono with a black Obi belt and a white undershirt. The second mouth on the back of her head is said to be Mio's, constantly hungry and causing Rin pain if not fed. Abilities: Rin's powers include having a large mouth, long tendrils (hair), enhanced speed, teleportation, and voice mimicry (although it's actually Mio mimicking Rin's voice to trick people).
