Various historical fighters are summoned from across time to wage war on each other, with the fate of the world in the balance.

The Drifters are a league of exemplary warriors from across history - the samurai Shimazu Toyohisa, the ninja Nasu, a World War 2 pilot, an Imperial Japanese naval officer, and a host of others - brought to an alternate Earth to fight and destroy the Ends, a similar group who have decided to take over the Earth instead of protecting it.
