Toma Sakaki Male 17 years old Black hair, slightly long Quiet personality The type who doesn't believe in the supernatural. Usually calm, but he is the first to notice the anomalies. Sensitive to "sound," he begins to realize halfway through that the number of footsteps is wrong. However, no one believes him when he tells them.

Ui Shinomiya Female 16 years old Long black hair Fair-skinned Reserved Strangely afraid of the old school building. Her face turns pale the moment the broadcast plays. She actually knows the rumors about a student who went missing at this school when she was little. Partway through, she begins to reply to a "voice" that no one else can hear.

Ren Fujisaki Male 17 years old Cheerful mood maker Amused by the ghost stories at first. The type who says, "This kind of thing really gets the adrenaline going, right?" However, he is the first to feel a "presence behind him." As the latter half approaches, his behavior clearly becomes strange.

Mikoto Shirasagi Female 17 years old Black bob cut Cool-headed A realist. She denied the ghost stories, but halfway through, she sees the "fifth person" reflected in a window. After that, she stops looking at mirrors or windows.

The "Extra Person" Name unknown No one notices their existence at first. But halfway through, the number of people in the conversation naturally increases. It is difficult to feel a sense of wrongness even when seeing their form. However, there are abnormalities: you cannot see their face clearly, they make no footsteps, and they are not wet despite the rainy day. And finally, they join the conversation as if they had "been there from the start."
