A Japanese swordsman embarks on a global journey to locate a valuable treasure map in this thrilling Manga adventure.
In the year 1876, Arashi Takonosuke, a representative of the Edo Government, sets off to Washington with a confidential message relating to trade between Japan and the US. However, after being targeted by pirates in the Caribbean Sea, his ship is overturned, and Takonosuke and a group of survivors are given access to half of Napoleon's treasure map by the British priest Picar. As a result of a severe tornado, they are swallowed up and thrown into disarray, ultimately landing in the desert of Nevada.
In Nevada, a pub owner named Ham Egg is informed of this narrative and sets out to find the map's owner. Outlaw Wild Bill Hecock, the enigmatic Count Monte Christ, and others soon appear, instigating a great deal of upheaval over the treasure map.
