COVER Corp. revealed plans for significant roster changes at Holostars, its male VTuber agency, with six streamers set to end their activities over the coming weeks. Hanasaki Miyabi, Kishido Temma, Rikka, Arurandeisu, Minase Rio, and Kageyama Shien will host their final streams on staggered dates, starting with Miyabi and Temma on June 8, followed by Rikka on June 9, Arurandeisu on June 10, Rio on June 25, and Shien on July 10.

The announcement comes as Holostars continues adjusting its operational structure following an April reorganization statement. Despite their departures from the main Holostars brand, Rikka and Kageyama Shien will maintain a presence within the COVER Corp. ecosystem by continuing as part of PolaPoriPosuPo, the agency's band project.

Twelve other Holostars members will continue streaming under the brand, including Kanade Isuru, Astel Leda, Yukoku Roberu, Aragami Oga, Yatogami Fuma, and Utsugi Uyu, ensuring the agency maintains active roster representation.

These departures mark another chapter in the ongoing evolution of Holostars since its 2019 launch. The agency has experienced personnel shifts before, but the scale and timing of this announcement suggest COVER Corp. is making deliberate decisions about the brand's direction and resource allocation. The staggered departure dates allow each streamer to host individual farewell streams rather than simultaneous closures.

For long-time Holostars viewers, the news signals the end of an era for several popular personalities while maintaining continuity through those continuing with the agency or transitioning to related projects like PolaPoriPosuPo. The band project's retention of Rikka and Shien suggests those streamers will remain active within COVER Corp., just in different capacities.
