Cutlass

Tsubasa and Tokimaru are brothers, though not related by blood. Tsubasa lost his mother at sea and recently begins to see strange visions. One day, he and Tokimaru are dragged into another world, where they are given a chance to find and rescue Tsubasa's mother.

In this foreign place, they meet a mysterious pirate named Shroud, who owns a great ship, and a strange man called Leda. Both men join the boys on their journey, which is full of different adventures. As they travel, Tokimaru starts to suspect there is more to Tsubasa's background than he knows.
