Biography

No.7’s NEUTRINO singing library uses the Kotori Koiwai singing-research database and publicly credits Koiwai as its voice performer. The character site separately lists VOICEVOX speech and research datasets, with illustration by 猫屋敷ぷしお. One character links singing, speech and research uses without establishing an autonomous AI persona.

Singing data, speech data and software editions are distinct resources. The first public appearance and a representative song chronology remain unverified. The CV is an official production credit, not a private-identity inference.
