The Black Moon Pirates were just offshore of an island called Sabaku, a desert island home to Marine Base 13. Knowing the risk, they set for port to pick up supplies. Hiding the ship by some rocks, some of the crew, including the Captain comes ashore and head towards the town there. Several others arrive to the island as well or were already there that are and may be a part of the Black Moon Pirates.
Meanwhile, with the Marines, Captain Barabara Brito visited the local Inn, bearing news of a pirate ship coming to port, aware it was belonging to the Black Moon Pirates, where their Captain, Roald D. Emrik and parts of his crew had bounties on their heads, Emrik's being 28 mil Beri. Within the inn, she finds Commander Caim, who was on a day off enjoying himself. Lieutenant Reimu Kairo isalso seen to be in the Inn, doing her own business as a Doctor. After they converse, Brito leaves the inn in search of her squad and finds the drunken rabble harassing a fishwoman, Lorelei, someone not local to the island either. Angered by their conduct and threats to kill Lorelei, Brito lashes out at the marine responsible by cutting her sword across his chest, which ensues a scene. By that point, Commander Caim and Lieutenant Kairo had been alerted within the Inn and exit to bear witness Brito's assault.
Unhappy about this, Caim intervenes to prevent further harm and gets between Brito and the marine that was struck. This is where he proclaims to have her under arrest for assaulting a fellow marine with possible fatal intent. Coming quietly, Brito agrees and they are all escorted back to Base 13, several people witnessing the event, including plenty of the Black Moons and others.
With a time lapse here and there, Rear Admiral Dalton Margaret orders Brito to be executed by dawn, instead of having just a few weeks incarceration. the Black Moons debate now a plan to possibly free this now captive Marine Captain and find themselves with plenty of volunteers among the crowds, who most had a respect for Captain Brito, for she was few who they didn't fear like most Marines would instill just by being mentioned.
