The Acumate Pirates are a group of pirates from an unknown region, under the captaincy of Devil Dias.
Under Dias, a pirate with a bounty of 60,000,000, the crew planned to head to the New World.
However, Dias was captured and sold into slavery to Saint Rosward on Sabaody Archipelago. Dias eventually attempted to escape, only to have the bomb within his collar shackle to detonate and his body was dragged off by the Marines.
The crew's fate is unknown due to the capture of their captain, but Sentomaru noted that Dias was not prepared for the New World due to his low caliber.
