KAMITSUBAKI STUDIO singer Isekai Joucho opened her official fan club, 1209Carat., on September 5, 2026, and is part of the studio's ongoing restructuring into KYOKAI STUDIO and UNKNOWN LAB, which will affect how virtual artists are recruited and produced.
Isekai Joucho, a virtual singer with KAMITSUBAKI STUDIO, opened her official fan club, 1209Carat., on September 5, 2026. The club's name draws on jewel motifs from her early concept material, extending the visual identity she has built since her KAMITSUBAKI debut into a paid membership space. Annual membership costs 10,000 yen, and monthly membership costs 800 yen, with benefits including advance ticket reservations, exclusive videos, galleries, wallpapers, newsletters, and birthday messages. Annual plan members receive a physical membership card and card holder.
The fan club launch coincides with a major restructuring at THINKR, the parent company that runs KAMITSUBAKI STUDIO. On September 5, THINKR announced it spun off KYOKAI STUDIO and UNKNOWN LAB from KAMITSUBAKI STUDIO, joining KAMITSUBAKI STUDIO and ALLT STUDIO. The restructuring directly affects how virtual artists like Isekai Joucho are managed, as the new studios will participate in the upcoming THINKR AUDITION 2026, a joint recruitment drive covering both virtual and real artist tracks. The audition opens October 5, and KAMITSUBAKI STUDIO executive producer PIEDPIPER is among those selecting candidates.
THINKR also launched SINGULAR LIVE on the same day, a live streaming platform built for its affiliated artists. This platform, the first initiative of PROJECT SINGULAR, handles regular live streams and revival screenings of past performances, with a PRIME subscription tier at 880 yen per month or 9,680 yen per year. For Isekai Joucho, this platform offers another channel to reach fans, complementing her new fan club. Her activity sits within a broader push by THINKR to consolidate artist content and monetize fan engagement.
