With the first wave over, Kizuna—a boy forced by his sisters to play using a girl avatar—returns with his party to their laid-back life and their voyage through the open seas. When a storm seals them in an inescapable map called the Sea of No Return, their boat is drawn toward a massive haunted pirate ship.

While searching the haunted vessel, Kizuna is inadvertently thrown overboard—alone. He’s swallowed up by the cold seawater, and by the time he realizes it, he has drifted ashore on a far-off beach.

Will Kizuna manage to survive without anyone on this deserted island? Or will conflict arise with the mysterious Pekkles that live there?
