UltraLMTM is running Patch 1.1 from November 14 to December 31, 2026, a two-month schedule of programs and collaborations that ends with a Patch 1.2 announcement program on December 30. The brand's first full-group key visual, drawn by Makai no Jumin, shows all 8 CREW members.
UltraLMTM is a VTuber brand run by GANYMEDE Inc. and produced by k4sen, who belongs to the CREATOR division of the esports team ZETA DIVISION. The brand announced six first-generation members on September 28, 2026: Riina Koga Fluorite, Amari Mahiru, Yuime Yuina, Hanasake Sei, Washimi Daisho, and Yayoi Chiu. Their first streams ran over two days at 19:00, three members on October 5 and three on October 6, each on their own YouTube channel, with a program on the UltraLMTM official channel at 20:30 each day featuring the three who had streamed plus k4sen. Profiles, visuals, a trailer, and X accounts for all six launched with the announcement. The brand's stated concept is "Beyond imagination, ideals squared."
By the November 12 announcement program, the roster had grown to 8 CREW members, and the brand's first full-group key visual, drawn by Makai no Jumin, showed all eight. The same program set Patch 1.1 to run from Saturday, November 14 to Thursday, December 31, 2026, as a two-month schedule of programs and external collaborations rather than a single launch stream. The roadmap includes the first episode of official program Ultra Limi Totsu and LMTM The k4sen on December 27, and ends with a Patch 1.2 announcement program on December 30.
Across the three announcements, the operation has moved from naming a six-member first generation to running a numbered patch schedule with a larger roster. The Patch framing, borrowed from online game updates, is how the brand structures its calendar: debut streams in October, then Patch 1.1 through the end of the year, with the next patch announced before the current one closes.
