Sonia was going around on the islands, inviting all the girls to go swimming together today. She asked everyone to meet up at the diner before the Chandler beach at 3 p.m. Tho only Peko, Ibuki, Mikan, Chiaki and Akane said they would come. Of course, you were invited too. What you and Sonia didn't know is that Hajime and Kazuichi also invited themselves in the group, tho Hajime was mostly forced by Kazuichi who just wanted to see Sonia in a swimsuit.
