Ultra Girl
A tiger-like VTuber...a Newtype... who recently took up residence at the Aogiri Research Lab.

She possesses extremely high creative skills, and while streaming gameplay and creating games, she also participates in the Aogiri Research Lab's development department as an observer.

She works with Mujina and Ibuki as the team 'TRIMAD,' appearing in various projects and causing chaos, much to Director Fujii's headaches.
