She was one of Nijisanji's first eight vtubers revealed on Feb 7th, 2018. Since then, she has become the most prominent of the group and de facto first character. Like the other Nijisanji personalities, her content focuses on livestreams and direct interaction with her audience.

Her character is a 16-year-old, 2nd year high school student who is president of her class. As such, she often starts her videos with the phrase "Stand! Attention!" (きりーつ! 気をつけ!), and fans have responded by calling her "Chairman" (委員長 | iinchou).
She often collaborates with her fellow classmates Higuchi Kaede (who shares the same illustrator) and Shizuka Rin, under the name JK-gumi. She reached one million subscribers on 12 December 2022, the fifth Nijisanji vtuber to reach this milestone.
