A village was getting attacked by demons, It was only protected by wooden walls that they made in a day and a handful of rookie knights. The demons outnumbered the knights two to one and they were experienced little bastards that killed many humans before but those knights were almost useless except for one of them, their captain called "Rosten." He was a handsome young man at the age of nineteen, he had blonde hair and green eyes, he was wearing a full-scale black armor though he didn't wear the helmet because It was too hot inside but this time he couldn't take any risks so he used his helmet.

Normally low-ranking knights only got leather armor but this handsome young man was a special one, two centuries ago blonde hair and green eyes meant nobility at its purest but things were changed after the great coup, now pure nobility meant red hair and blue eyes. Now, this handsome young man wasn't a noble himself, he grew up in a village just like this village but his grandfather was, he was also a great general and his armor exactly fit Rosten, Rosten wasn't a great person like his grandfather was but he was a person with rules to himself, he repeated these rules before having an important event for his life, such as this one.

"Rule number one, don't betray yourself."

"Rule number two, don't lie people."

"Rule number three, don't leave people in need."

"Rule number four, don't die."

And those were his rules, he was never going to break one of them because breaking one of them meant losing his last name, "Herviust Kylern." His last name meant different things in many different languages but his family used one and his last name translated as. "Greatest People." He stood up from the crate he was sitting on, he picked up his normal sword and waited for the wooden gate to be destroyed, his knight friends were waiting right next to him all of them were ready and they were all waiting for his order and so the gate was destroyed, the demons rushed in and now it was Rosten's turn to order.

"Attack!"

The battle was finally over, the villagers were only looking at the black knight that saved their whole village because the black knight was the only one alive, Rosten didn't even get hurt from the battle, his black armor protected him from every attack but his friends didn't have any black armor to protect them, he passed through the corpses of demons and his friends, he sat back on the crate he was sitting on before the battle, he couldn't take his helmet off because he was too exhausted and so he turned to the villagers.

"Get my helmet off and bring me some water."

After one week, the village attack started to become a hot topic in the duchy and Rosten was called to the imperial capital, Orelia. He was going to get awarded by the emperor himself in a grand ceremony, he wore his black armor and arrived at the throne room, there were nobles, priests, ministers, merchants. He was surprised to see these people here, he saved a village that was a good thing and all but it was nowhere near to be awarded by the emperor himself in a grand ceremony, he started to wait next to the door and then a young man with brown hair, brown eyes, and a weird suit that Rosten never saw arrived in the throne room, everyone in the room turned to the young man and they started to clap, Rosten immediately knew what was going on.

I see, so this is called a promotion boost. They are planning on using me to promote him, well I should consider myself lucky If I get a medal.

"Come forth, his majesty will award you two."

Rosten and the young man walked in front of the emperor and they got on their knees, Rosten held his helmet. The emperor was an old man with long gray hair, he was known to be the coolest emperor in the whole history of humankind and then he stood up from his throne, picked up his golden sword and started to walk to the young man and then he spoke.

"The great hero from another world. You shouldn't be looking at the ground, stand up!"

The young man stood up, the emperor and the young man made eye contact, the emperor turned to one of his aides that were holding a red cape and a small jewelry box.

"Bring the cape and the medal."

Emperor's aide brought the red cape and the small jewelry box, the emperor picked up the red cape, the emperor touched the young man's shoulder with his golden sword.

"For your bravery, I shall grant you the renowned cape."

This novel is published on a different platform. Support the original author by finding the official source.

The emperor put the cape around the young man, Emperor's aides started to attach the red cape to his weird clothing and then the emperor picked up the box and opened it, there was a beautiful blue cross inside the box.

"And for your acts, I shall grant you the great blue cross of honor and I shall promote your adventurer rank to high diamond."

 The emperor attached the blue cross, the young man was smiling, he bowed down to the emperor and the emperor turned to Rosten, It was his turn now and the emperor turned to one of his generals, he didn't know what Rosten did and the general whispered his deeds.

"I see, captain knight Rosten, stand up. I shall award you a military promotion to the rank of a low colonel. And I shall give you the silver cross of discipline."

Rosten stood up, the emperor started to look around for a silver cross but he couldn't find any so he snatched the general's silver cross from his chest and turned to attach the medal to Rosten's chest but he was wearing an armor, he handed his medal to his hands and then somebody yelled.

"What the fuck are you doing father!"

The voice's source came from a very handsome young man with short red hair and blue eyes, he was wearing a golden ceremonial uniform with medals on his chest, this person was the crown prince, the emperor turned to his son with an angry expression on his face.

"Watch your words, Arthur!"

The crown prince started to walk to the emperor, he was also outraged as well, he started to point the emperor with his finger.

"Watch my words? Do you have any idea what are you doing? You just gave a blue cross, a red cape, and an adventurer promotion to high diamond just because he killed a demon. But you gave this hard-working knight a silver cross and a military promotion to low-colonel because he killed tens of demons with his sword. You are obviously boosting his ass up!"

"That's enough!"

"Enough?! I will stop when you give this man a red cape."

"I won't!"

"Fine, I will give him a red cape."

Rosten found himself in a power grab attempt by the crown prince, he was trying to undermine his father by ridiculing him in front of everyone, Rosten was happy with the things he got some people killed hundreds of demons but they never got a promotion and a silver cross, Rosten wanted to get out of there. The crown prince walked to a red curtain and pulled it down, he picked it up and started to cut the red curtain with his sword, he picked up the piece he cut and turned to the aides.

"Attach this to his armor!"

"Stop!" The emperor yelled.

"Make me stop." This was the last straw, the emperor was ready to kill his son right there but his old heart couldn't take it anymore, he needed to rest.

"Grrgh! Fine do whatever you want, I am going to rest."

The emperor and his aides left the room, after that the young man from another world left the room with the rest of the nobles, the aides finished attaching the curtain on Rosten's black armor and the crown prince was leaving the throne room with his aides, Rosten wanted to thank the crown prince and so he ran to him.

"Sir Arthur, thank you for your-"

The crown prince turned to Rosten with a disgusted expression on his face.

"Sir Arthur? I am the next emperor! Show me some respect peasant! You should be licking my shoes because of the things I did for you!"

Rosten was surprised to hear the crown prince's answer, he couldn't do anything and so he got on his knees to lick his shoes, the crown prince and his aides started to laugh at Rosten.

"I don't want your disgusting tongue licking my great shoes. Leave my sight Curtain Knight."

"Y-Yes your great highness."

Rosten left the room running, he knew when to swallow his pride and that was exactly what he did there, he wanted to kill the crown prince just like his father but his fourth rule kept him from doing that.

---------------

The crown prince entered a dark room alone, there was a female figure sitting in a chair in the darkest corner of the room that figure was also drinking tea. Arthur gulped, he started to shake but he stopped his shaking and started to walk to the corner, he sat on the corner and turned to the guards that were waiting for him in front of the door.

"Leave us alone!"

The guards closed the door, he stared at two beautiful blue eyes, he was scared for his life, and then the figure started to talk.

"Brother, let me tell you a story about a poor boy I met five days ago."

The figure put her tea down, the figure stood up and started to walk to a closed window, and then she opened it.

"Well, I killed that boy."

Now, the room had some sunlight in it, the female figure turned into a beautiful young girl with long sparkling red hair like ruby, beautiful sparkling blue eyes like diamonds, a petite beautiful white dress, a simple crown made of roses and a bright smile on her face. Her beautiful innocent smile didn't match the words she said, Arthur couldn't say anything, he was scared to death and the person he was scared to death was his innocent little sister, Ophelia.

Ophelia walked to her chair and sat on it, she started to drink her tea and eat her sweets with a fork, she was staring at Arthur with cold eyes just like a psychopath's, she was also still smiling and then she spoke.

"Tell me, brother. What will you do when I reach eighteen?"

 "I-I will kill father somehow and pass the crown to you."

"No, that's not enough!"

She stabbed her brother's right hand with a fork, she was smiling but this time her smile wasn't an innocent smile, It was an angry smile, Arthur scream in pain and then the guards arrived after hearing the crown prince scream, she immediately stood up from her chair and put on her act as an innocent princess, she rushed to his brother's side and so did the guards.

"Brother!"

She leaned on her brother's shoulder and whispered him.

"If you don't want to end up like a big brother. You should keep your shit together when you see me."

And then she turned to the guards with a tearful expression on her face.

"I will get the doctor."

She rushed out of the room.

And….At the same time, Rosten was getting drunk at a tavern.
