Mito Tsukino is a NIJISANJI-affiliated VTuber who is set to voice Hecate in the anime film The Ribbon Hero, premiering on Netflix on August 8. She is also part of the six-liver Cherry Cherish merchandise lineup, which launched at the Nijisanji Official Store on July 9.
Mito Tsukino appears in two recent Yomimono stories, both from 2026. The first, from July 8, places her in the Cherry Cherish merchandise line, a coordinated goods release themed around cherries. The lineup includes six NIJISANJI livers, with Tsukino among them. The goods, ranging from 350 yen cards to 3,500 yen plushies, went on sale at the Nijisanji Official Store starting July 9. The second story, from August 4, announces her casting in The Ribbon Hero, an anime film based on Osamu Tezuka's Princess Knight manga. She voices Hecate, one of five new cast members revealed in the final trailer.
The two stories establish Tsukino as an active NIJISANJI talent with a merchandise presence and a voice acting role. The film marks her first role in a feature-length anime, a detail stated in the trailer announcement. Her casting is part of a broader trend in the film, which also features two other NIJISANJI VTubers in their first feature-length anime roles. The film premieres on Netflix on August 8, and the trailer previews the English dub.
Together, the stories show Tsukino's current standing as a NIJISANJI liver involved in both merchandise and animation. The merchandise launch and the film casting are separate events, but both reflect her ongoing participation in NIJISANJI activities. The film's premiere date is the most recent concrete fact available.
