Amigo Pirates

The Amigo Pirates are a group of pirates that serve under Shiki. They ride in a submarine and the majority of them dress up as mariachis. They are lead by Largo and his vice-captain Colt. Their group is welcomed to become Shiki's 51st pirate division, but are given a condition first, which is to kidnap Boss, a giant beetle who was apparently stolen from Shiki, and is now living in Little East Blue.
