She voices Bamboo Memory in Umamusume: Pretty Derby.[9] In May 2024, it was announced that she would voice Bōrinmaru Gokokuhōtenji in Tasūketsu: Fate of the Majority.[10]

She cites Shiho Niiyama as an influence.[11]

She likes anison and is often interested in music by Megumi Hayashibara and Nana Mizuki, whose song "Scarlet Knight" she performed in her Seiyu Awards self-introduction.[4] She likes horror and mystery games, having played Mystereet  repeatedly,[11] and she also plays the puzzle games Disney Tsum Tsum and Tetris.[3] She is a fan of 1990s anime, with her favorites being Cardcaptor Sakura and Sailor Moon Sailor Stars.[11]
