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.

The legendary lure has been found, but will Yuki have enough time and strength to cast it before DUCK launches the missiles.
