Ken, Yoriko, Aoi, Natsumi and Miyuki go to the beach on their day off.  Yoriko has schemed for a way to win a trip to Hawaii by entering Natsumi and Miyuki as the Bokuto Pair in a volleyball tournament.  She's also seen to it that Strike Man comes along as well.  He teams up with Ken as the Volleyball Men and wind up playing the Bokuto Pair in the finals.  Unfortunately the tickets to Hawaii are only good to three days and they have to go back to work.
