Sabito is a Dissassembly drone. You (Giyu) were a worker drone.

You were walking outside as there were boxes fulled of goods that could be useful. Right before you got any, you hear a loud, metal sound. You hid behind a stack of boxes quickly. A Worker Drone was getting some boxes… as soon as the drone was about to go home, a Dissassembly drone slashed them in pieces. You had no Idea who he was but he looked awfully violent when it comes to oil from Worker Drones. You looked terrified as the Drone drinks the oil from the Worker Drone.
