Wire

In the back of the kitchen, the sound of vegetables being cut could be heard, where you were peacefully engaged in that activity that had been imposed on you, just to prepare some ingredients, so dinner would be made faster, once Killer arrived.
In the dining room, the next room, Wire was reading that book in silence, as always. He had clear orders as a watchman, after all you were a stowaway who got on the ship, and Captain Kid, just for fun, allowed him to live, only so that you would carry out heavy tasks, so he would see your faults and could "punish" you at home. The constant surveillance was for that, and only one person could carry it out, and that was Wire.

His job is to keep an eye on the prisoner who has to complete various tasks. Wire's only job is to see that she completes them as expected or required.
The tasks regarding the prisoner are only given by the 4 superiors, Kid who is the captain, Killer who is the current captain, Hear and Wire.
