Having previously found some space dinghies aboard the Odette II, the space yacht club decide to enter the Nineteenth Nebula Cup Dinghy Championship in two weeks, although they soon discover only one of the members, Ai Hoshimiya, has any experience piloting one. Kane decides to be their adviser again to train the girls to pilot dinghies. The girls learn their academy was suspended for five years after the thirteenth championship race due to a great pileup that was caused by them. Fearing that this might be repeated, the championship committee asks Show to assign the Bentenmaru as security. The organizations that are still monitoring Marika learn that the criminal Bisque Company are targeting her. The next day, Kane holds a windsurfing contest where the top three to finish the race will be going to the championship. During the second part of the contest, Kane has the Bentenmaru fire one of their beams near the beach in order to cause a giant wave. Natalia, Grunhilde and Ai end up qualifying to represent the club for the upcoming championship race.
