Genki Rockets
After graduating high school, Yasuda decided to pursue a full-time music career in spite of advice given to her to attend university instead. In 2013, Yasuda changed agencies and debuted as a solo singer under Sony Records with her Japanese name, Rei Yasuda, debuting with "Best of My Love", which served as the ending theme to "Space Battleship Yamato 2199". Unlike Genki Rockets, the song's music video was shot on location instead of a green screen. In its music video, the UFO came to the world where the civilization hasn't been developed, which Yasuda found that that contrast is interesting. Kenji Tamai, who Yasuda worked with in Genki Rockets, helped produce and prepare for her solo debut after her high school graduation. In addition to singing, Yasuda also continued modeling, starting the fashion blog "Nylonista" for Nylon Japan and performing for Nylon's special stage in Girls Award 2013 Autumn/Winter. In April 2014, she started shoe blog for ABC-Mart, accompanied with the release of her single "Passcode 4854." She participated in Escada fashion event in April 2014 and Tokyo Girls Collection festival once a year from 2013 to 2016, with the 2013 Autumn/Winter being her first live performance. She was featured in Sendai Collection 2014 and her song "Inside Out" became the brand's promotional single for the brand's event in August 2014.
