Biography

RIME is the third Musical Isotopes singing character, developed from RIM’s voice. Its official description emphasizes a husky timbre. Creators arrange its performances in CeVIO AI rather than having RIM record each user’s composition.

The software launched on October 25, 2022, after original songs had begun appearing that July. Release materials also document joint covers of “Madeki” and “Mahou” with KAFU, placing the character within a multi-author music project before the software went on sale.
