My name is Cook Kolstein. I was born into a family of knights for three generations, and I was raised to be a knight from the moment I was born. Last year, I was promoted to the rank of platoon leader at the age of 21. I was a captain in name only, and although I had to do some tedious work for a small allowance, time passed normally.
But now I have a headache... my stomach is churning... and it's all because of the man in front of me, Masaru.

A few days ago, a group of goblins suddenly appeared and he was ordered to kill them. Normally, we would have gathered more people to subdue them safely, but this time, the battalion of knights had been dispatched because of a report of orcs, so it was up to our platoon.
It is a little strange for me to say this, but our platoon is surprisingly elite.
There's Havoc, who's young but has remarkable skill with a spear; Jami, who can handle attacks with his shield and hit you with it; Eldam, who's a little older than the rest of the Knights, but whose skill is suitable for actual combat and is a reliable expert; Guy, who's a little light on his feet but is good at scouting and reconnaissance; and I'm not sure what to make of that.
We're a platoon that's known for being the best and most talented in the coastal city of Portarym. ...I've been told that I'm too individualistic and uncooperative, but I'm willing to put that aside.

But things went wrong when I heard about a village where villagers were fleeing from a pack of goblins. There were more than 15 goblins in the village, and I was getting nervous, thinking that if I wasn't careful, I would get hurt. I relaxed and went to check on him.
What I saw was another figure chasing after two smaller figures, and it was unusually fast. Thinking that a child was being attacked, he rode his horse and saw that it was a goblin being chased and a commoner was chasing it. One goblin seemed to catch up with him quickly, so Eldam, Guy, and I took our bows and fired arrows at the remaining goblin.
However, it seems that this was a miscalculation, as he chased after the other goblin, slaying it as he went, and ran towards the goblin with the arrow flying without slowing down. A man panicked, but before he could speak, the arrow reached the goblin and stopped him in his tracks. As he pondered for a moment what to say, Buggy announced himself, "This is the Coastal Guard of the Kingdom of Greitas! Hey, you there! Who the hell are you? I've just had a bad day, and he's mad at me for saying my name so proudly from above.

When I managed to introduce myself, I thought he was just a commoner, but his tone of voice was sometimes sharp and sometimes polite, and I could tell that he had received a good education. Only royalty, aristocracy, a few rich people, and big merchants who deal with such upper class people have proper education. As he entered the fishing village, thinking that he had hit a bad match, he saw the corpses of goblins lying in rows, just like the path he had taken. He looked at him in surprise, and saw that he had barely a drop of blood on him... but that wasn't the end of his surprise. There was even the corpse of a goblin riding a giant boar, said to be a wall-breaker. As if ignoring our astonishment, he gave appropriate instructions one after another to clear the scene. I listened to his instructions and simply carried the goblins away. Also, the whole roasted monitor lizard we had for dinner was delicious.

When we left the fishing village and arrived at the village, his attitude suddenly became stern. At first I thought he was upset with the villagers who were reluctant to pay him, but it turned out that his goal was to free the beastmen. When I was confronted with the fact that we humans were vile invaders who had treated the innocent beastmen badly, I realized that something had to change.

On the way back to the city by horse and cart, he was drunk from the jolting of the cart and vomited out his stomach with a pale face. As I was smiling at the normalcy of his appearance, he jumped out of the carriage and started running alongside me. At first I tried to smile, but my face only grew tighter when I saw that he didn't seem to be getting tired any time soon.
Problems do happen, and even a bandit appeared and blocked our way. The bandit was instantly and gleefully defeated and interrogated by him... it was hard to tell which one was the thief. My hardships seemed to continue, and my headache and stomach ache soaked my body.

...I don't want to fight with him, and that's definitely one of the reasons why I've accepted that he's right.
But most of all, I'm afraid. His overwhelming physical abilities and thoughts.
I'm sure I'm nothing compared to him, having been educated only in combat, but I'm sure he's thinking far beyond what we can even imagine.
I have a feeling that he will change this world that I've always thought was different... and maybe I just want to see it.
