Satoi's presence was discovered; this would make it significantly harder to get out unnoticed. Satoi watched the proceedings unfold. He didn't approve of the old man's methods of discipline but he wasn't in a position to object at the moment. Instead, his brain surmised that the farmer had some sort of martial arts training, judging from his physique and the way he carried himself. Regardless of what particular discipline the farmer practiced, it would make things more difficult to take him down. However, that only applied if Satoi fought him in direct combat.

As the boy left the barn, Satoi rifled through his pockets. He moved as little as he could to prevent any creaks that could give away his position. He slowly drew out his water skin, carefully extending his arm outwards towards in the direction opposite to where the large farmer now faced, apparently searching the barn for the intruder that prepared to strike him down.

Satoi dropped the water skin, letting It land on the hay with a soft thud. The farmer snapped around to look at the source of the disturbance and Satoi got ready. As the large man bent down to investigate, Satoi silently dropped from the rafters. The farmer turned at the creaking in the rafters, but by then it was too late. 

Satoi's fist lashed out, connecting cleanly with the old man's head, knocking him to the floor. Satoi landed gracefully onto the floor before rushing forward, grabbing the large man in a choke hold, covering the old man's mouth. He was strong, the farmer, but not as strong as Satoi. His struggles ceased after a time and Satoi released the body, letting him slump to the ground. Light footsteps coming from outside alerted Satoi that the boy was coming back in so he sidestepped to a shadowy patch by the barn, trusting his dark uniform to conceal his form. The boy entered and gasped in alarm at the man's prone form, rushing forward to investigate. But as he passed by Satoi's hiding spot, Satoi delivered a single chop to the boy's neck, slamming him into the floor. 

Satoi flipped the boy over and checked his pulse. It was somewhat faint and a little slow, but still evident. Satoi breathed a sigh of relief and retrieved his water skin, brushing the hay off of it. The large man was the same. Satoi liked to think that he was a professional, he didn't like taking needless lives. But despite his training, Satoi was perhaps not as hard headed as he should be for a ninja.

As Satoi opened the door to leave the barn, he turned back and looked at the boy. He was thin and had looked rather tired, and the big man's treatment of the boy didn't exactly display a healthy relationship. Satoi rummaged in his bag once again and took out a piece of dried meat, walking over and hiding it under the boy's clothes. An token of apology was in order, he reasoned. A good ninja leaves others completely unaware that he was ever there. A ninja normally takes responsibility for their own mistakes but the boy had already suffered due to Satoi's incompetence and he wanted to make up for it a little bit.

As Satoi exited the barn, he briefly wondered if he should've waited for them to stop looking for him. But he dismissed the thought quickly and went on his way. He had somewhere to be, after all, and good ninjas stuck to their schedules.
