VTuber Mike Neko said on a livestream on November 4 that a person she had reported to prosecutors has been arrested on suspicion of defaming her and of obstruction of business by fraudulent means — interfering with another party's work through deception. She said a detective called her that day to confirm the arrest.
The suspect, who went by the name Tahagami Nagi, was arrested on suspicion of defamation and obstruction of business by fraudulent means, she said. Mike Neko said she had asked a lawyer to handle the matter and had filed criminal complaints several times since May 2025.

She thanked police officials in the stream. She did not explain details of the investigation, saying they could affect later procedures.
Years of posts, AI images and pressure on bookings
Tahagami Nagi is said to have run accounts mainly on X and to have repeatedly spread false information and slanted posts about several VTubers and related groups under multiple names. The campaign against Mike Neko was especially persistent, she said.
According to her own stream, she was targeted for a long period with AI-generated images meant to demean her, including ones depicting her kneeling, and with false claims spread to provoke pile-ons. She said the abuse, which she dates to 2022, left her mentally cornered, and that disclosure requests and criminal complaints have cost her more than 800,000 yen.
She also described behind-the-scenes interference: efforts to obstruct her music work, including a debut with Pony Canyon, and pressure on events not to book her. Besides Tahagami Nagi, she said she has filed criminal complaints against more than 10 people.
Mike Neko said she will keep taking whatever steps are needed. "I keep fighting without giving up not only for my own sake, but because I absolutely do not want to waste the feelings of everyone who has believed in me and kept supporting me," she said.
She is an independent VTuber — a virtual YouTuber, a performer who appears through an animated avatar — with more than 540,000 followers on X and about 1.01 million YouTube subscribers. She has also published a novel and posts fan art.
