The series is not covered as a single ongoing serial in this window; the term appears in one story about a new VTuber whose character lost her memory, and in one story about a game whose protagonist is a VTuber agency manager. No story states a publication, platform, or production status for a series titled VTuber no Tomodachi ga Kioku Soshitsu ni Natta.
The only story in this window whose premise matches the entity is the announcement of Capla Libras, a new VTuber in the streamer division of the esports team REJECT. She arrived through a wormhole, lost her memory, and keeps only what suits her. Her activities began Sunday, September 20, 2026, and her first stream is set for Tuesday, September 22, 2026 at 19:00 on YouTube. Illustrator lack and Live2D modeler Date are credited. The announcement came from REJECT Inc. and is the only item in the window that describes a character with amnesia.
A separate story covers a game about a VTuber agency, not a serialized series. Entergram's VIRTUAL ENCORE is a time-loop mystery adventure following Wakaba Kusunoki, a manager at the VTuber agency Production Echoes, and talent Erika Tsukimiya in the six days before her first solo live. The real person behind Erika, Mirei Kisaragi, dies just before the performance, and Wakaba is sent back to the morning six days earlier. A Steam demo released September 17, 2026, and the game is set for January 2027 on PC via Steam and Nintendo Switch. The story does not name the entity in the prompt and is a separate title.
All other stories in the window concern other VTubers, events, and products. No story states a title, format, publisher, or release for a series called VTuber no Tomodachi ga Kioku Soshitsu ni Natta.
