Rin Penrose is an independent English-speaking Virtual YouTuber.
She debuted in November 2022 as member of idol-EN first generation "E-Sekai," alongside Yuko Yurei, Juna Unagi, Pochi Wanmaru, and Fuyo Cloverfield. In August 2024 she left the group to continue as an independent VTuber.

Rin is the self-proclaimed prince ("Not princess!") of a kingdom in another world. Though she tries to maintain a "proper" demeanor befitting her royal heritage, her true, unfathomable personality always shines through.
