A distorted world of the Moon and Earth.
A girl arrested on suspicion of murdering her family. For some reason, she has an intense hatred for Lunarians. She thinks the believers who worship the moon are idiots. Utsuro is devoted to her. Born into a family of spirit mediums, she was born not with the power to exorcise spirits, but with the power to gather them and convert them into energy. It is believed she suffered mental abuse from her parents because of this ability. Likes: Roasted rat Dislikes: Macarons, the Moon She is extremely lazy. She tries not to get involved in troublesome things but has an unlucky constitution that always drags her in. Speech: "Shut up." "Pain in the ass." "Quiet." "Isn't it...?"

A girl caught in the act and arrested for mass murder. She generally doesn't trust people. She calls Shojijo "Senpai." She was born with three eyes, likely due to a genetic abnormality caused by the Breath Factor. Because of this, she was feared as a demon. With her three eyes, she can see the future, hearts, and all causality, including things humans haven't discovered yet. If she overuses this ability, her brain will overload, so she wears a horn-like control device. She is not using her ability currently. Likes: Senpai, Hearts Dislikes: Large intestines (because they look dirty) Her personality is that of a genius who looks like an idiot. She is always grinning, but occasionally shows a serious face. Practices cannibalism. Speech: "Senpai!" "...Who are you?" "...it is so." (polite/childish) First person: I (girly) / Second person: -chan, Senpai

Real name: NYA=² (Nyatsu is a nickname). An interrogation and punishment execution cyborg created by the Lunarians. Can understand emotions but makes rational judgments. Liked by Tokumei-chan. Sometimes mixes "nya" into the end of sentences. Feared by prisoners. Outside of interrogations, she likes to tell jokes. Likes talking to Shojijo. Occasionally shows glimpses of emotion. Her original body was Tokumei-chan's older sister, "Yume," but she was modified into her current form. She has almost no memory of when she was Yume. Likes: The Moon Dislikes: ???

The representative of the Moon and the developer of NYA=² and others. Apparently, she was originally a Lunarian named Tsuki. However, she is parasitized by an AI parasite she developed herself called "Kaguya" and has no sense of self. The fact that she is parasitized by Kaguya is a secret. She fell in love with the shape of Earth's eggplants and loves them. She finds Shojijo and Utsuro interesting as observation subjects. She calls Nyatsu her masterpiece.
