It was this branch which is responsible for the region of Conomi Islands which is where Cocoyasi Village belongs. It was also the one responsible for turning a blind eye on the activities of the Arlong Pirates and their tyrannical reign on Cocoyasi.
They were also tipped off by Arlong and invaded Nami's and Nojiko's home and confiscated all 93,000,000, that Nami had gathered to buy her village's freedom. Their commander is later beaten up by Nami for it. Humiliated and injured, Nezumi furiously retreated to this base to report Monkey D. Luffy as a pirate to the Marine Headquarters.
