UniteUp!: -Uni:Birth-

Fuga asks to change the motif for the Release Battle and for some reason, he's also avoiding Daiki and Eishiro.

The sMiLea Production idols are suddenly sent to an overnight training camp by Lin and Maoto. Although they're enjoying their stay by having snowball fights and doing other activities, PROTOSTAR began feeling overwhelmed by the responsibility and pressure of leading the joint live performance. When Daiki sees the three members of PROTOSTAR lack the confidence to direct the senior groups, LEGIT and JAXX/JAXX, he begins venting about his frustrations.

PROTOSTAR, LEGIT, and JAXX/JAXX form a deeper bond with the overnight training camp. As they work on improving for the joint performance, Akira strangely shows up late to practice. Banri and Chihiro are worried about Akira, who isn't acting like himself. They head to Kikunoyu Hot Springs to talk to him when they realize Akira's mother isn't there. After wondering if there is any way they can support Akira, what will Banri and Chihiro do?!

With the help of all the idols at sMiLea Production, Akira is able to perform at the joint concert.
