Kazuma calls up each of the group the next morning, inviting them to visit the beach with him the following Wednesday. Everyone agrees, and the gang spends a fun and exciting day playing in the sand and in the water. Madoka takes the opportunity to ask Ui about her relationship with Kazuma, relieved to hear that she considers him more of an older brother than a love-interest. Finishing up their stay with a game of suikawari and volleyball, the group head out at sunset. On their walk back home together, Ui curiously asks Ibuki about her and Kazuma.
