Years, later, Luffy sets off in search of the "One Piece," said to be the greatest treasure in the world...

Nami's sick! Now the Merry Go is without her navigator! Luffy and crew have but one choice--find land and hopefully a doctor.

With Nami's life on the line, Luffy sets out through the snow-laden fields to find this doctor, witch or not!
