It's been a long time since we've seen our old friends, and now they're back together. Akari and Sam are having lunch, and they decide to hang out by the floating island. Sam reminds Akari that he's always been scared of the slide on the island, and Akari reminds him that it's training to make him braver. They jump off the swings, and the two of them train to slide down the island. Akatsukin is super nervous, and he challenges Akari to a duel. The winner will be who can slide the most down the slide, but Akari is super confident that he can do it. He says he'll leave the peace of the island in his hands, and that he doesn't want to exist for the sake of "aqua's sake" .
