OTAGROUP's recent activity spans a collaborator drive for Meta Grandma's channel, a rookie-event win by Avivi VTuber Yaya, and a new single from Hitone Iri. The studio operates a label, OTAGROUP Music, and works with the Avivi partner agency.
OTAGROUP's three most recent stories are spread across its label, its partner agency roster, and its own talent. The most recent is the Rookie Top Challenge win by Yaya, a VTuber affiliated with the Avivi partner agency. The event ran from August 1 to August 7, 2026, and Yaya took first place. Avivi is a partner agency of Avvy, the avatar creation and streaming app operated by AnotherBall.
The story immediately before that is a Web3-adjacent (Web2) project: OTAGROUP opened applications for the Meta Grandma Silver Shield Project, a collaborator drive aimed at bringing the YouTube channel of late-stage elderly VTuber Meta Grandma to 100,000 subscribers. The channel has roughly 80,000 subscribers. The project notes the timing could work as a Respect for the Aged Day plan. Hiroko, the 84-year-old original member from Mihara City, debuted in December 2022.
Earlier, OTAGROUP Music released the original song Aromatic Arcana by OTAGROUP talent Hitone Iri on June 24, 2026. The track was composed and co-written by Koji Matsuzaka, who praised Iri's vocal range. Iri described the release as a major step toward her dream.
