<Comment from "Souya Ichika">
"ichica" is a girl born from my singing voice — I'm Souya Ichika.
Just as I have met so many wonderful people and received countless feelings and inspirations through my activities as a VTuber, I hope that she, who has only just been born, will also come into contact with many people's thoughts and emotions, and discover many different worlds along the way.
And I sincerely hope that one of those people will be you.

May ichica's future be filled with countless feelings and lots of beautiful music.
