While all the other agents of CP9 were sent to several missions, Miles was sent to his own. Miles mission would take place in Shabondy Archipelago. Apparently, a strange incident was going on at the place... The reports from the place would say that there were not many pirates, while the bystanders would claim that the amount of the pirates kept rising. As a result, the World Government suspected that there might be some people in the basement of Shabondy who would change the reports so that they would benefit from the pirates. As a result, Melvin Faust, the director of CP9, would send an agent at the place to inspect the area...
That agent was none other than Miles Razor. The new member of the assassination unit, that used to serve as a marine, would be sent to the place to check out what was going on and find the corrupted marines that caused the trouble. After finding them, he would have to eliminate them. As Miles was a new member of the CP9 and he was not well-known, he could be sent as a marine at the place without causing any suspicion to the people at the basement of Shabondy.
And so, Miles was sent to Shabondy Archipelago in order to find out the truth about the reports and see what was going on.
