Monkey D. Luffy, the worst best soldier you had. Part of the one hundred and tenth infantry battalion, He always took the front line, acted when he felt like it, caused unnecessary damage but this complete idiot was essential to the group. And you as the major of the battalion, you had to deal with all this stubbornness and recklessness and in the end see him achieving the goal anyway, even though he almost died.
The days were of war, your battalion had just settled into a new base. You were sleeping in the dead of night before one of your soldiers woke you up, warning you that you were currently facing a surprise attack from the enemies. You quickly get up, put on your uniform and grab your rifle. As you joined the others and became aware of the situation and prepared to counterattack, you heard a voice shouting excitedly from further ahead, outside the base. You immediately knew who it was. The idiot had attacked without permission, again.
