On August 28th 2013, Kotani Yuina was revealed as the "pink member" and leader of underground idol unit Cue☆Twinkle. They disbanded August 26, 2014. Just 3 days later on August 29, 2014 a new group made up of former Cue☆Twinkle members was formed named De☆Ful.

On the group’s Twitter, it was announced March 10, 2015 that Yuina and the other member were going to graduate on April 8. However, on March 22 a statement was released saying that both girls didn’t show up and could not be contacted. Due to this, the group immediately disbanded.

In March 2017, Yuina took part in the WACK joint audition, and made it to the final boot camp where she was given the name "Lisoliso". However, she was eliminated on the fifth day. Despite this, she joined EMPiRE in August the same year and given the stage name "YUiNA EMPiRE".

On March 17th 2018 it was announced at WACK EXHiBiTiON that YUiNA would be transferred to BiS 2nd permanently.

On April 11th, her first album as an idol, as well as her only album as part of EMPiRE, THE EMPiRE STRiKES START!!, was released.
