Natsuki sets his heart on creating a tidal power generator that utilizes the ebb and flow of the ocean's tides. He dives back into the ocean to find some materials and salvages some resin from the ruins of Ryuuji's family's factory. As soon as he gets back he gets to work. As they are working, Natsuki and Ryuuji exchange heated opinions over how the generator should be built. Atri intervenes and the two guys become closer friends. Meanwhile, a suspicious-looking character peeks at them from outside of the school....
But if Natsuki's wish will come true...
...لكن إذا كانت أُمنية ناتسكي ستتحقّق
Aber wenn sich dafür
dein Wunsch erfüllt …
Pero si así cumplo tu deseo…
Pero si así cumplo tu deseo…
Mais je suis prête à tout
pour réaliser tes rêves.
Però... se così posso esaudire il tuo desiderio...
Mas, se assim seu desejo
vai se realizar, Natsuki...
Но… если так я исполню вашу мечту, Нацки…
