The Acumate Pirates are a group of pirates from an unknown region, under the captaincy of Devil Dias.
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.
