At the end of the year, Momo and Sai have come to relax at a hot spring inn in Hakone, taking advantage of the short off-season of Idorizing. With Olin joining them, they are thoroughly enjoying the baths and delicious meals! However, in the midst of this, Momo is suddenly nominated as a candidate for the Newcomer Award and must participate in a special match on New Year's Eve. Caught off guard by the sudden match arrangement, Sai becomes overwhelmed with coordination and desk work, leaving Momo to struggle alone with her training methods. Unexpectedly, it is the strongest "Queen" of Idorizing, Matsurizaki Ellie, who reaches out to help her— but is it just her usual whim, or something more?
