Rikka

Biography

Rikka first streamed on 20 October 2019. His official self-introduction describes music, guitar-accompanied singing and songwriting as central to his work; the page links Re:Hello world and a 3D anniversary programme. His robot persona is fictional lore, not evidence of autonomous AI performance.

The May 2026 official notice gives 2026-06-09 as the end of his streaming activities, and the consulted profile is marked accordingly. This entry preserves his performance history without presenting him as a currently streaming talent.

This starter dossier checks official profiles, concert credits and an activity notice; the full recording and performance history still needs expansion. Character lore does not establish a performer’s private identity or nationality.
