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.

After wondering if there is any way they can support Akira, what will Banri and Chihiro do?!
