She voices Yogawa Sekai in KAMITSUBAKI CITY UNDER CONSTRUCTION, served as game master in its TRPG project, and hosts a program on FM Yokohama. With Haruka Sarubi she has run the radio program "Kamitsubaki Hosobu" since May 2021.

Musical style

Her voice is praised as clear and clean, with a powerful, slightly low register and a sweet, girlish freshness that carries both youth and maturity. She cites Hikaru Utada as an influence, often listens to Fujii Kaze, and grew up hearing BoA. She loves game music, especially Yoko Shimomura, and was influenced by Kingdom Hearts. Her visuals are fantasy-like and European, and her costume design shifted from a black-and-white dark tone with Nemophila I in 2022.
