Ayatsuno Yuni (아야츠노 유니, JP: 純角ユニ) is a female Japanese and Korean-speaking VTuber affiliated with StelLive. She debuted in August 2022 as a member of YUME Percent's "YUME B Generation" alongside Airi Kanna, Kogame Hinatsu and Huwari Dojiko, but in December 2022 that agency disbanded, and she ended her activities on her original channel.
In January 2023, she re-debuted into StelLive with a new channel, as part of its Generation 1 "Mystic" unit together with Airi Kanna. She mainly streamed on Twitch until it ended service in South Korea, after which she moved to streaming on the Korean-language platform CHZZK, while uploading videos to her new YouTube channel.

While the other unicorns headed towards extinction, Yuni was left sealed and alone. Time passed, and she woke up on Earth. She later decided to join StelLive to protect herself, and blended into human society. Whether she would succumb to corruption or pass on her purity, was left as her choice to make.
