Hoshimachi Suisei's 2026 is split between her own label and the hololive machine. She announced Studio STELLAR, her personal agency, on March 22 during an acoustic stream marking her 8th anniversary and birthday. The agency handles her solo music production, streaming, merchandise, and fan club work with COVER Corporation and NERD Inc., and she stays a hololive production talent for group and collaborative work. The same announcement carried a 2026 arena tour, "Once upon a Stellar," across Yokohama, Kobe, Nagoya, and Fukuoka.
Midnight Grand Orchestra, her unit with TAKU INOUE, restarted after roughly two and a half years. The first EP, Travelogue I, was announced on May 28 for an August 19 release, then arrived digitally only: the limited CD bundled with soundtrack music for an original anime project was canceled after production problems at an external company. The February 2027 concert Project: Allegro remains on the schedule.
August brought "GUM & DROP," her first release under the new system, written with Sabrina Claudio and Paris Alexa and co-composed by Mikhail Beltran and Xansei. She also confirmed a December 20 joint live with tuki. at K-Arena Yokohama and two WONDERLIVET 2026 appearances in South Korea, solo on November 20 and with Midnight Grand Orchestra on November 21.
Merchandise and crossovers fill out the rest. PalVerse Hololive vol.2 lists her among five talents, and Bandai Spirits opened reservations for a Sazabi figure in her colors. She appeared in hololive Dreams' miComet event, in a Steins;Gate escape game stream, and with Hatsune Miku at a Lotte-sponsored Chiba Lotte Marines game.
