Yuki is the new kid, Haru is an alien, and Natsuki is the fishing prince. Three unlikely characters brought together for a unique experience, which might lead to saving the world.

Keito is coming home from the hospital and Yuki wants to get her a gift. He takes on the challenge to catching a tuna, her favorite fish. This will lead the boys to an area of water off limits and closer to Haru’s goal.

During the search for Sakura, Akira confronts Koko and Haru and demands to know why they are here on earth. The duo explains their situation, but bigger plans are already in motion against them.
