Donuts runs the smartphone rhythm game Blackstar -Theater Starless-, which enters its 7th anniversary event in September 2026, while its idol rhythm game Tokyo 7th Sisters ends service on August 12, 2026, after 12 years, with an offline version in development.
Donuts is running two mobile rhythm games on opposite trajectories. Blackstar -Theater Starless- enters its 7th anniversary with the Inferno event, which runs September 1 to October 1. The event adds GOD and DEVIL cast visuals, two new songs, customizable song parts, a sugoroku map, and voice notes. A daily roulette mini-game hands out up to 70 free pulls per day, and anniversary cast members are obtainable through gacha tickets earned by playing.
The studio's other mobile title is closing out. Tokyo 7th Sisters ends service on August 12, 2026, after roughly 12 years and 6 months. The main story concludes with the Stella MiNE group's arc. An offline version preserving story, music, and cards is in development, and the franchise continues with concerts and merchandise.
