Chiyu is in training for an upcoming track and field event. However, she suddenly loses the ability to perform the high jump at her usual standards. Pegitan becomes worried and after consulting his treatment books, comes to the conclusion that Chiyu has a case of the 'Yips'. On the day of the event, Daruizen creates a MegaByogen to disrupt the activities. The Cures fight the MegaByogen and defeat it. The freed Ice spirit gives a new elemental bottle to Chiyu, who also regains her confidence and manages to complete the high jump.
