Summer vacation has started and the fishing lessons have been going well. Yuki has decided it is time to get his own fishing pole, but what he wants and what he can afford are vastly different. A question to Ayumi lands Haru, Yuki, and Natsuki jobs on a fishing boat.

Haru is scared; Akira is trying to convince Natsuki about what is happening, and Yuki and on his way back to Enoshima. But when JFX takes over a military commander, the worst case scenario comes true.

Duck has lost its fleet, and their last resort is a missile bombardment. Yuki and his friends have to convince them not to while at the same time fish for their lives.

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