She reveals that she killed her twin in a game of who-is-fake, showing a capacity for dark acts alongside loyalty and fear. Her presence anchors the trio’s longing for escape and meaning.

A patient haunted by past abuse who hallucinates his molested teacher. He forms a bond with Coco and Satoru and participates in their dangerous explorations beyond the asylum walls. His trauma fuels impulsive choices, including painful memories that surface under stress. He shares the fear, tenderness, and protective instincts that drive the group’s risky pursuit of the end-times spectacle.

Friend of Tsumuji who joins the wall-climbing adventure and the trio’s search for meaning beyond the fence. He reacts with fear and curiosity as they encounter dangerous discoveries, like the severed hand, while trying to navigate a world that feels both close and unknowable. His presence adds a hopeful but cautious counterbalance to the group’s reckless bravado.

A distant paternal figure implied by the parents who drop Coco off at the asylum, establishing a fractured family background that shadows her sense of belonging and authority. His absence frames Coco’s dependence on her own strength and on the company of peers within the asylum. He is part of the backstory rather than an active presence in the events.

A priest who emerges from the church to debate God with Coco and Tsumuji, offering a Bible and an invitation to read. His dialogue probes belief, doubt, and the appeal of apocalypse as a fate-choosing moment. He embodies a source of guidance that is at once comforting and enigmatic for the youths.
