Avsnitt 21

Today is the day I go to school during summer vacation. As usual, Spank and Aiko, who are going to school, encounter Seiya, who is playing a big fight against delinquents on the way. It was Spank who was so strong that I couldn't help but be dazed. At that time, Aiko's student ID card, which fell on the road, forced Seiya and Ryo to have a duel. The place is going to settle by swimming far to the sea - a large rock off the coast . Aiko and the others stop them, but Oyama, Nezu, and even Spank are the ones who make them two of them, so they finally jumped into the sea...
