She was a student before joining BiS, but she struggled to talk to any of her classmates, even though she wanted to. She was always very shy.

She spoke about her first live performance with BiS in her initial interview. She barely managed to sing at all, she cried throughout and could barely speak. She says it’s so embarrassing to watch again.

While in BiS, however, her confidence and talkativeness and improved drastically, to the point that she is barely recognisable to how she used to be at the time of her debut.

After joining BiS, she did a mini gravure photo shoot of her wearing her swimming costume from the BiS reformation audition and sat in a bath of ice. Article is here.

She wanted to be an idol after speaking to an idol otaku friend who said she should become one. At first she thought about starting a part time job as a local underground idol, but it took her a long time to debut as there was lots of behind the scenes work to be done. During this time, as she had nothing to do, she mainly stayed at home.

In the first BiS LEAGUE election, July 31, 2018, she came in 6th place, keeping her in BiS2nd. She earned 5,786 votes total.

Previously a founding member of the Nagoya based idol group Attain Music, under the name Utatano Soyuru From March 13, 2016 to August 11, 2016. She also uploaded dance covers on streaming site niconico.

She joined BiS September 3, 2016 through the BiS reformation audition. Her parents let her go to the audition, despite thinking that she wouldn’t make it.

She is also a member of the WACK collaboration group HOLY SHiTS.
