She joined DreamS Kenshuusei on August 17, 2013 and graduated on November 20, alongside 5 other Kenshuuseis. She is also the younger sister of HoshiBoshi Pro TθPAZ leader Nagase Ren.



On August 17, she, alongside 7 other girls, were added to the DreamS Kenshuusei program after passing the seventh DreamS Kenshuusei auditions. They made up the 7th Generation DreamS Kenshuusei.

She became a backdancer for the NeXus Summer Concert Tour 2013 ~Hanabi Matsuri~ concert.

On October 20, Icchan announced on YouTube to the Polaris Alpha members and the viewers that there will be a 2nd Generation member added, in order to spice up the group and challenge the 1st Generation members. It was announced that it was 7th Generation DreamS Kenshuusei Nagase Mirei. She will debut in their 1st live at the 2013 Winter ~ DreamS! Fuyu no Soyokaze ~, with their new single "Chiisana Kiseki", which will be released on December 22. Polaris Alpha will officially be the first DreamS group to have generations. All the members were shocked at the sudden news, but exclaimed that they will welcome her with open arms, and were excited to have a new member. Nagase has been dubbed the "Small Miracle" of Polaris Alpha, and the producers of DreamS hope that she will have much to contribute to Polaris Alpha. Her official color was picked on a TV corner of the DreamS anime Butterfly Days by Polaris Alpha themselves.

Nagase, alongside Hirasawa Hikari, Sugisaki Yui, Nakamoto Marina, Fujisaki Tomoyo, and Otokawa Sana, will graduate from DreamS Kenshuusei on November 20, and officially begin activities as a 2nd Generation member of Polaris Alpha on November 27.
