Ep. 15: Tsugumi and Hajime visit an island where Mina Minato lives under the control of her paranoid aunt Fujie.

15

Tsugumi experiences a vision of a girl on an island, prompting her and Hajime to travel there. They meet Mina Minato, who resides with her domineering and paranoid aunt, Fujie. Fujie restricts Mina from leaving their small island, a behavior stemming from a broken psyche caused by a past traumatic event. Mina’s boyfriend, Yuji, was previously attacked by Fujie when he attempted to escape to the mainland. Upon discovering that Fujie murdered her mother to prevent her departure, and realizing she is in imminent danger of being killed next, Mina acts in self-defense to send her aunt to Hell.
