Overview
TSUMITOBATSU (罪十罰) is a virtual singer unit under the GIRLS REVOLUTION PROJECT label of KAMITSUBAKI STUDIO, consisting of MIKOTO, YUNAGI, and HINAGESHI.
The unit is known for aggressive dance tunes that carve the brand of sin with voices echoing through the virtual world. The girls exchange secret pacts and doze off in the endless night. Alongside SINSEIKI, TSUMITOBATSU is one of the two core units of the Girls Revolution Project.

Position within the project: together with SINSEIKI, TSUMITOBATSU forms the “heart–sin” two-axis structure of the Girls Revolution Project. Each has a self-contained world-view while intersecting through joint songs such as “Kaihen”, “Gense Kaiki”, “Nibiiro Gentou”, “Shujin Kouro” and “Chromatic” — a systematic experiment by KAMITSUBAKI in running multiple groups in parallel.

TSUMITOBATSU’s first full album Kaihen -Tsumi- was released on 29 October 2025. Its eleven tracks are the culmination of the “sin” side of the world-view.
| # | Track | Production |

Album structure: a mirror to SINSEIKI’s Kaihen -Shin-. The shared title track “Kaihen” closes the “heart” and “sin” themes on their respective discs. TSUMITOBATSU’s production line-up (Hitogoto, Umetora, Shiino Mirin, Hirata Yoshihisa, tokiwa, biz and others) skews decisively toward aggressive rock and heavy electronics.
