Yumi is a VTuber and VStreamer who streams video games and art on Twitch. Her VODs are also on YouTube. Her first language is English, but she knows some German and Japanese.
Yumi is a manifestation of subconscious thought. She does not exist. You only see her when your subconscious wills it. You need to wake up soon. Your family misses you... Yumi spends her free time roaming your dreams. When this becomes stale, she manifests and plays video games and draws.
