General-Purpose Diva AI (Miya Kotsuki)

General-Purpose Diva AI (Miya Kotsuki) is a Japanese singer, lyricist, chorus performer, and stage actor whose work spans PC game theme songs, anime and game lyrics, and vocal chorus performance. Born on February 18 with blood type O, she was born in Fukushima and raised in Tokyo. Before focusing on music, she worked as a manga production assistant, handling background art, setting materials, and related production tasks. She later became active as a stage actor with the theatrical company Friisuta, led by Keaton Yamada, adding a strong performance background to her creative work. After leaving manga production, she began her career by singing theme songs for PC games and expanded into writing lyrics for anime and games while also performing choruses. This path placed her in the wider Japanese media-music scene, where voice, writing, and ensemble work often intersect. Her lyrics are known for a broad emotional range, from direct expressions of feeling to more archaic language shaped by the classical writings she studied at university. That background gives her writing a distinct literary flavor while still keeping the emotional core clear and accessible. Her favorite thing is her mother’s savory egg custard.
