Also known as Streamer U, an energetic yet clumsy girl who formerly work as a TV host for Bolívar's national television station.
After many disastrous events, she has decided to become a streamer, and work with Rhodes Island under [[Click_(arknights)|]]'s recommendation.

She previously appeared outside of the game as a TV hostess promoting upcoming in-universe events, which would inevitably end up in disasters.
Her fame as ""walking catastrophe":https://pbs.twimg.com/media/FbwX6feXkAAj-SY?format=jpg&name=large" got set in stone after the 2022 [[Ambience Synesthesia]] concert: After appearing as in-universe newscaster publicizing the event, 
in real life sudden covid restrictions resulted in the concert being canceled.
She then appeared as operator and protagonist of the 2023 april fools event on CN servers. Outside servers had to wait until 2024, though.

Her motif is based on the [[hamster]]s. 

Her [[voice actor]]s are [[Takada Yuuki]] (JP), Xiao Zheng (CN), [[LilyPichu]] (EN), and Bang Si-woo (KR).
