Biography

Tohoku Kiritan’s NEUTRINO singing voice is based on the Tohoku Kiritan singing-research database and publicly credits Himika Akaneya. Its official description associates a strong, cute tone with pop and idol songs, illustrating a path from research recordings to a creator-facing singing tool.

AHS released the CeVIO AI singing edition on February 12, 2021, placing the character in another editing and synthesis system. Availability on several platforms does not make their versions or launch dates interchangeable; this account separates the documented product milestones.
