On April 1, former Dempagumi.inc member Kozue Aikawa announced that she has gotten married.

Alongside her announcement, Aikawa uploaded a new dance cover video on YouTube set to samfree’s "Luka Luka★Night Fever." The video, as well as the photos attached to her marriage announcement post, were filmed at the same wedding venue used in ENGAG.ING’s music video for "Wedding High Five."

Although the announcement was made on April Fools’ Day, Aikawa confirmed the news, stating, "It’s true!! I registered my marriage yesterday!"

Aikawa began her career in 2008 as an "Odotte Mita" (dance cover) video creator, posting dance performances to various songs. In 2018, she joined DearStage Inc. and became a member of the idol groups ENGAG.ING and Dempagumi.inc.
