Nijisanji VTubers Step Into Voice Acting for Tezuka's 'Ribbon Hero'
Nijisanji VTubers debut as voice actors in Netflix's 'The Ribbon Hero' anime film.
Three Nijisanji VTubers are making their voice acting debut in THE RIBBON HERO, an anime film arriving exclusively on Netflix on August 8. Tsukino Mito, Runrun, and Debidebi Debiru join a cast that includes established voice actor Yoshimasa Hosoya and Yusuke Tezuka for the project.
The film adapts Osamu Tezuka's classic manga Princess Knight, following Princess Sapphire as she battles Nergal after losing her homeland. It's a significant moment for the three VTubers—crossing from streaming performance into theatrical voice work represents a tangible step into traditional anime production, even if the release is digital-first.
Tezuka's Princess Knight remains one of manga's foundational works, and a Netflix-exclusive adaptation signals the platform's continued investment in anime tied to legacy properties. Whether this debut leads to further voice acting roles for the Nijisanji talent remains to be seen, but the placement alone—alongside established names like Hosoya—suggests the studio took the casting seriously.
