"School Swimsuit and Vampire"The students learn that they are to choose a school activity and Tsukune is having a hard time choosing when he comes across the swimming club with Moka. He wants to go but Moka doesn't. What Tsukune doesn't know is that water has a purifying effect on vampires and drains their powers. When they get to the pool both Kurumu and Yukari try to garner the most attention through events as the head of the swim club tries to get Moka away from Tsukune so she could have him for herself. What the swim club wants from the new members is more than you might think?
Note: Ep 5 is based on chapter 3 of the manga
