United Butterfly! Rei Ryugazaki, Nagisa Hazuki, and Gou Matsuoka create a recruitment video for the swimming team for the upcoming school year. While filming, Gou finds an old recruitment manual left from the previous members of the club with the strategy "PKH Higashi" which they believe to be resourceful for the video. They investigate to find out that it was the nickname for "Perfect Killer muscle, Handsome Azuma" a member of the swim team who had attracted many female members onto the team with his appearance. Though disappointed, the event inspires Rei to complete the video. Asahi Shiina makes a cameo in this segment during their investigation.
