Mitsuba is a VTuber affiliated with KAMITSUBAKI STUDIO who is currently running a TaPrize online lottery collaboration offering original limited goods through July 13, 2026.
Mitsuba, a VTuber under the KAMITSUBAKI STUDIO label, is the subject of a single dedicated story in the coverage cluster. The most recent report, published June 19, 2026, details a collaboration with the online lottery service TaPrize. From June 19 to July 13, 2026, fans can play for a total of 27 items across six prize categories, including a T-shirt and mini canvases, all exclusive to TaPrize. Each play costs 700 yen, and the lottery has no losing tickets, guaranteeing a prize per attempt.
Beyond this collaboration, Mitsuba does not appear in any of the other six stories in the cluster. Those stories cover other KAMITSUBAKI STUDIO artists and events: a charity stream featuring Rima, Koko, Kakyoin, and Hiyashi; the debut EP and mini-live of the unit Kuusou; a Hong Kong concert by virtual singer Kaf; a streaming release of the KAMITSUBAKI WARS 2026 event; and a live re-staging by Isekai Joucho. None of these stories mention Mitsuba or provide additional context about her activities, career history, or role within the label.
The dossier therefore rests on a single source. It establishes that Mitsuba is active in merchandise and online lottery collaborations, a model that avoids sell-outs by guaranteeing a prize per play. No further information about her streaming schedule, music releases, or live performances is available from the provided coverage.
