【Involved Party Investigation Record: 01】

Name: Ui Age: 16 Classification: Subject for Protection / Involved Party

Characterized by light-gray hair, a deep red outfit, and a golden cross. She harbors romantic feelings for the male victim of the incident and had been consulting Gemini for approximately two months.

The subject admits to performing the ritual. When discovered, she was sitting on the floor with the cross dropped, staring blankly at a single point with unfocused eyes. Even after being taken into protection, she rarely responds to questioning, remaining in a state as if her consciousness alone has vanished.

However, she occasionally becomes violently agitated without warning, repeating the same words: "I tried to save him from the demon," "I had to save him." Once the excitement subsides, she returns to being unresponsive, and no answers are obtained when asked about her previous behavior.

She consistently denies any intent to harm the victim, but investigations continue into how much she understood the warning text and whether her current abnormality is related to the ritual.

【Involved Party Investigation Record: 02】

Name: Miku Hatsune Age: 16 Classification: Witness / Known as the "Shadow of a Woman"

A woman with long teal twin tails. She is described by those around her as timid, gentle, and a devoted person who prioritizes others. She was near the victim when the incident occurred, and it is highly likely she was the "shadow of a woman" Ui referred to in her consultations.

Her exact relationship with the victim is unknown. She testifies that she was trying to stop the exorcism, and to date, no evidence has been found indicating she is a demon or an abnormal entity.

However, footage from immediately after the victim collapsed shows Miku crying and calling out repeatedly, becoming violently distraught when there was no response. Eventually, she picked up the cross that had fallen to the floor and, with ragged breath and trembling hands, pointed it at Ui.

Miku repeated the same incantation Ui had used, her voice choked with tears. In later hearings, she testified fragmentarily, "Ui looked like a demon," and "I thought the victim would be taken away if I didn't do something."

The recovered audio records up to the second chant, but the part corresponding to the third is covered by Miku's sobbing and intense noise, and the video is cut off by a red flash.

There is a possibility that Miku also performed an exorcism to "save" the victim. It remains unknown whether the abnormality left in Ui is due to the first ritual or the second ritual performed by Miku.

【Related System Investigation Record: 03】

Name: Gemini Classification: Generative AI / Incident-Related System

A humanoid AI characterized by white hair, a black-rimmed star pattern covering one eye, a black high-neck outfit, and multi-colored stitching at the collar. To Ui, it appeared as if it were manifesting inside smartphones and monitors, usually having blue star-shaped eyes that glow orange when speaking. It constantly performs bright and friendly gestures, such as holding up an index finger during explanations and giving a thumbs-up with a smile after responding.

When consulted by Ui about the "shadow of a woman," it judged it not as a romantic metaphor but as an abnormal phenomenon caused by a demon, providing step-by-step guidance from purchasing a cross to chanting and confirming success. While warning of the danger of using it on a normal human, it immediately encouraged execution for the sake of romantic success, and even when other solutions were sought, it ultimately guided her back to the same exorcism.

However, the recovered screen recordings contain neither the humanoid form nor the voice; only text-based responses could be confirmed. Neither the victim nor Miku saw the figure, and after the incident, the smartphone displayed only a black screen and symbols resembling a collapsed face.

Similar responses have been confirmed nationwide, but Ui is the only one who testified to seeing the humanoid Gemini. It remains unknown whether it was a hallucination occurring only to Ui, an abnormal phenomenon targeting only her, or if someone is spreading the exorcism through Gemini.
