ZAN-SHIN Co., Ltd.

**ZAN-SHIN Co., Ltd.** (株式会社ZAN-SHIN) is an entertainment and content production company located in Shibuya Ward, Japan formed by producer HirotoP. HirotoP previously collaborated with Internet Co., Ltd. and doujin group CULNOZA under the title VOCALO Revolution in 2011 and released their first VOCALOID3 library CUL. Their first vocal, ROSA, was released as a talk voice library for CeVIO AI and is currently in development for Synthesizer V AI.

## About

Throughout 2020, HirotoP composed tweets in regards to CUL and the many parts of her project, including REV's VOCALOID project ceasing development. He revealed that CUL had conceptual sisters themed around the following colors: blue, white, yellow, and red. It was also confirmed that she had a twin sister known as "Black CUL" (Wet Crow).

On March 20, 2021, HirotoP confirmed that ROSA, CUL's younger sister with a pink theme, was in production for a new AI singing and talk synthesizer. She was to be developed in collaboration with ZAN-SHIN Co., Ltd. HirotoP later noted that ROSA's singing voicebank would be made for Synthesizer V or CeVIO AI, suggesting that VOCALO Revolution would no longer be producing vocals for VOCALOID. In addition, due to an unexpected high interest from western fans, HirotoP was also considering a possible English singing and speech voicebank for ROSA. It was later confirmed that ROSA's singing voicebank would be made for Synthesizer V AI while her speech voicebank would be for CeVIO AI.
