Shiroi (白井) or Shiroi Koyuki is a member of the 3rd Generation along with Foxtella and Rika . Currently in two of the project's major groups, Minna Musu 。and Rain=Bow . Her image color 'Royal Blue.'

She is known for being the most quiet in the group but when her confidence kicks in she's hyper. She's also known for her in-depth knowledge of the Sonic The Hedgehog series & Korean singer BoA Kwon.

Vocally, she's also known for having a clear voice.



In 2007, she started doing covers of Utada Hikaru songs on YouTube after becoming a fan of Kingdom Hearts.  By 2008, after discovering more Japanese singers she started covering songs on YouTube again, as well as performing onstage with a performance group known as UCAN Productions, which I'd been a member of for a while at that point.

2008 was the year I became an idol fan. The first idol song she ever heard was Yuke Yuke Monkey Dance by Berryz Koubou :) She continued to sing alone until 2013 which is when I started to participate in annual and one time singing projects.


She entered Danshi Joshi Project with the other Third Generation members and was in three groups, Minna Musu。 and Rain=Bow
