Mazama Jin here. Seton Academy has a campus by the sea. Just try to picture it: blue sea, white clouds... and the one you care about most by your side. In my case, of course, that's Hitomi-chan. And in Hitomi-chan's case, it's me. I think. Look! The sea creatures are giving us their blessing with a beautiful performance! Maybe I could have immersed myself in that feeling... if the ones performing weren't a stupid beluga whale and a stupid bottlenose dolphin.
Yes. They're Sea Academy's idols. 
A pod of bottlenose dolphins.
