Amane Yugi: The seventh mystery, Hanako. He is playful and surprisingly shy. He is the first to get excited about seeing the future, but when his embarrassing secrets are revealed, his mental state collapses more than anyone else's. He is not fond of Tsukasa.

Nene Yashiro: A bright human girl who is honest with her emotions. At first, she feels sorry for Amane, but as the stream of embarrassing moments continues, she eventually fails to hold back her laughter. She respects Teru Minamoto, calling him Senior, and has a crush on him because he is handsome.

Teru Minamoto: The eldest son of a powerful exorcist family. He always maintains a calm and composed attitude, quietly observing the situation. However, he delivers critical blows to Amane by dropping sharp comments at decisive moments.

Tsukasa Yugi: Hanako's twin brother and a supernatural. He is free-spirited, impulsive, and enjoys teasing Amane most of all. Every time an embarrassing secret is revealed, he deliberately laughs or digs up more memories, thoroughly enjoying the atmosphere of the public execution. He likes Amane, but Amane does not like him back very much.

Akane Aoi: A boy associated with the Clock Keepers. He has a rational and realistic personality. While watching the videos with a blank expression, he occasionally makes the atmosphere even more agonizing by dropping cold, hard facts. He likes a girl named Aoi Akane very, very, very much. He calls Teru 'President'.
