I Got Caught Hunting Powerful Monsters in Secret Even Though I’m Just a Commoner, Which Led to Beautiful Girls From Noble and Royal Families to Come After Me - 1

Chapter 1: The Conversation Between an Older Brother and His Little Sister Attracts a New Storm

ーーーーーーーーーーーーーーーーーーーー

At dawn. 

I was hunting monsters on the beach, a little away from the house I lived in. 

“MUUUUUUU!!”

King Octopus, a high-level monster, roared as it extended its huge tentacles to catch me. 

However, I easily dodged its attack. 

This early in the morning, I could only rely on the moonlight as the sole source of the light. Normally, it would be close to impossible to evade King Octopus’s relentless attack but since I was wearing night vision goggles, I could easily see through its movement. 

And so…

“Summon Tank Breaker.”

I chanted and a weapon from my previous life that had been enhanced by magic appeared before me.

I immediately grabbed it and aimed the weapon at King Octopus’s head. 

“Take this!!”

I shouted, releasing a magic-infused shell at the same time. The shell flew incredibly fast, hitting King Octopus right on its head. The defeated octopus slowly sank into the water. 

“Gyuuuu…”

After checking my surroundings to make sure no one was around, I picked up a chunk of King Octopus remains that got splattered onto me. 

“If a commoner like me were to get found out defeating a high-ranking monster like this, it’s bound to cause quite a ruckus. Haa… If only I could take this monster to the Guild Association…. I could have earned a lot of money if I took on a quest to defeat King Octopus….”

I chuckled, laughing at no one but myself before heading home.

The next night, at a worn-down house. 

“Onii-sama! I’m home! Huh?? What is this??? What is this spherical food??”

“Oh, this is a dish called ‘takoyaki’.”

“Oh! Is this another new dish that you’ve developed, Onii-sama?”

“We-Well, yeah…”

“Whoa… It looks so delicious… Mmh~”

When my little sister returned from the magic school and saw the takoyaki I made, her eyes lit up excitedly. 

Takoyaki was a soul food that represented Japan, especially the Kansai region. However, this place was not Japan. This was a different world. Of course a dish called ‘takoyaki’ didn’t exist here.

I apologize to all Japanese people but please let me take credit for takoyaki.

“I defeated King Octopus yesterday so I decided to make takoyaki to celebrate. It’s delicious, you know.”

“Wh-Whoa…. Thank you for the meal!”

“Oi! Rina-chan! You need to wash your hands first before eating.”

Rina.. Can you even live on your own later? I’m getting worried….

Rina attended the most prestigious magic school in the world, the Central Magic School.

That prestigious school was considered to be the hardest school to get into. Not only magic, that school also excelled in other fields of study as well. Only the best of the best could attend this school.

Because of its notoriously difficult admission screening, thorough preparation had to be done from infancy if one wanted to enter this school. 

However, I used to live as a cram school teacher back in Japan. To be honest, the academic level in this world was only at the level of Japanese junior high school students. Furthermore, Rina could use magic (me too). As someone who loved isekai novels, I was well-versed in all sorts of magic. 

Thanks to my experience from my previous life, I was able to teach Rina various things over the years myself. She became an incredibly talented, strong and of course, very adorable little girl. She was talented enough to get into Central Magic School. Not only Rina was the first commoner to enter that school, but she also passed the exam with the highest mark between her peers. 

The daughters of dukes and even princes with royal blood flowing in their veins couldn’t even win against Rina. She was flawless in both practical skills and academic skills. She completely outsmarted the interviewer and during the combat ability test, she also won against a senior knight that was selected by the school.

In fact, the so-called honorable knight couldn’t even land a single blow on Rina. As a knight that received recognition from the Central Magic School, it was only natural for that knight to be prideful. Drunk with fury, the knight lunged at Rina. However, Rina retaliated with magic. The knight ended up receiving a wound so fatal that it would never heal for the rest of his life.

The school apologized to us for the knight’s misconduct and gave us a discount for our tuition fees. However, even with a discount, the tuition fees were still so expensive. 

Remembering the past made me overwhelmed with emotions. 

I was gazing at Rina affectionately when she timidly said..

“U-Um…. Onii-sama…”

“Yeah?”

“Can I please have a second?”

“O-Oh. Sure. You’ve finished eating my part too, huh?”

“Onii-sama’s cooking is just so delicious so I…”

“Well, you’re still in your growing period after all. It’s alright. I will cook all the King Octopus meat I brought with me.”

“Yay!~”

Rina and I ate takoyaki to our heart’s content. 

“Thanks for the food…”

“Fufu~ You have school tomorrow so let’s just relax for the rest of the night.”

“Ah, right.”

“Hm?”

Rina widened her eyes like she had just remembered something. She rummaged through her bag and then she handed me a piece of paper. Her expression looked gloomy. 

I took the paper and read the content. 

“Umm… A notice about tuition fees for next semester… Wha-What?!”

The new tuition fees were two times more expensive than the fees we paid when Rina enrolled into the school. 

As a top-notch school where the elites of the elites gathered, it was only natural for the tuition fees to be ‘top-notch’ as well. However, I didn’t expect the tuition fees would be two times more expensive than that time. 

“Umm… It seems next semester we will have a lot of practical classes so… It’s going to be more expensive than before…”

“I see…. Okay.”

“I-I knew it. I guess it’s better if I dropped out from the school after all!”

“Huh? Rina-chan? What’s wrong?!”

“Onii-sama, I can’t keep burdening you! With this amount of money, we could have a much more comfortable life. Onii-sama could’ve been happier…”

Seeing how dejected Rina was, I gently stroked her head. 

“You don’t need to worry about that. Our father and mother back in our hometown will also support Rina-chan wholeheartedly.”

“….But… Onii-sama, are you really fine with this?”

“Huh?”

“You’re smarter and stronger than me. You can easily defeat a King Octopus on your own even though a monster of that caliber requires a senior knight or mage of level 4 or higher to defeat. You’re working so hard just to be able to afford my tuition fees…”

“Ohh. So that’s what you’ve been worried about.”

“….”

Rine’s eyes were wet with unshed tears as she looked up at me. Her vivid purple eyes, encapsulated by her silky black hair that had the color of the night sky made her look so adorable. Not to mention her voluptuous bosom, a strong proof of her feminine allure. Objectively speaking, Rina was truly beautiful and adorable. 

I gazed directly into her purple eyes. 

“Rina-chan, I love seeing you shining bright. I want you to see more stuff, I want you to learn more and become stronger. I’m willing to do anything for that.”

“-!! Onii-sama…”

To be honest, I did have a bit of regret. However, 99% of what I said really came from my heart. I loved Rina a lot and I wanted her to flourish. As for the remaining 1%… Well, I actually wanted to live a slow-life.

In my previous life, I died from overwork from my job as a cram school teacher. Although I was blessed with cheat-like abilities, but that didn’t mean I longed for exciting adventures in a different world. 

I only wanted to be a good big brother to Rina. That was already enough for me. 

Rina… I really struggled in my past life. So please forgive this uncool brother of yours for not wanting to get any attention on me. I want to enjoy a slow life with my little sister while hunting powerful monsters in secret. Well, there’s that expensive tuition fee but still… Whether you know this feeling of mine or not but Rina… I just want you to shine. 

Rina suddenly jumped to hug me. 

“Ri-Rina??”

“Onii-sama…”

“Wha-What’s wrong?”

“Today… I was defiled again.”

“………”

“The son of the duke… The prince of the royal family… All of them keep staring at my chest…. Fortunately, there is a noble lady who is kind to me. They protected me but…”

“….”

“Onii-sama, please help me. Cleanse my body from the defilement caused by those beasts lecherous gazes.”

“I get it. Ah, I don’t have any other choice, do I?”

“Fufu~ Onii-sama, let’s go together.”

Recently, my little sister’s yandere side tended to get out of hand. 

We quickly headed to the open air bath that I had made for us. 

“Haa… Feels so good….”

“Well… It’s only a run-down and small bath though.”

“But… Onii-sama is here. That’s why I’m so happy.”

Our bodies were pressed together with only a towel covering our naked bodies. 

Well, to be precise, Rina was the only one pressing her body against mine. I didn’t do anything. 

Rine’s huge marshmallow touched my bare skin. Her twin valleys were so amazingly soft and beautiful. 

But yeah, it couldn’t be helped.

Rina had to do her best studying in a class filled with excellent noble gentlemen and ladies in the Central Magic School. She was the only commoner in a school full of top-notch nobles. It wouldn’t be an exaggeration to say this small reprise of comfort was the one that made her able to withstand the pressure and allowed her to maintain her top ranking in class.

I once refused this idea because even though she was my little sister, a grown up man and woman shouldn’t take a bath together. But then, Rina’s grades suddenly plummeted. The school immediately called and wanted to inspect Rina’s living circumstances in the name of a parent and teacher meeting. It was tough but we somehow managed to avoid making the school representative from coming to our run-down house. After all, it wouldn’t be good to have someone from Rina’s school to know about our living conditions. 

Alright. I just need to hold it in and offer my body’s warmth to Rina so she can focus on her study and stand tall between those noble students. 

I thought to myself while stroking Rina’s wet hair gently. Rina immediately snuggled against me like a spoiled little kitten. She was leaning her head to my hand, asking for more affection. 

Haa… The gap between her facial expression and her voluptuous body is too great. 

After taking a bath, we drank a bottle of cold milk before returning to our room. 

Rina put on her pajamas. Her hair was still wet but then, she suddenly widened her eyes. 

“Ah! Come to think of it.. I forgot to turn off the communication magical device!”

“Communication magical device?”

“Yes! It’s an expensive magical device I received from someone who had been kind to me. It’s a miraculous magical device that allows communication via voice from a distance!”

“O-Oh… I see.”

Rina quickly dug into her bag and took out an object that looked like a shining stone. She poured her magic power into the magical device and the light slowly faded away. 

Worried, I asked her.

“Could it be… Our conversation was transmitted to the person on the other side of the magical device?”

Then, Rina shook her head from side to side.

“It’s alright! There’s no indication of connection from Elena-sama’s communication magical device.”

“A-Alright.”

So the person who always treats my little sister kindly is Elena-sama, huh…. Wait. Elena?

“By Elana do you mean the daughter of the Duke Fibel family? The strongest woman in the kingdom?”

“Yes!”

“…………”

Rina-chan, Onii-chan is feeling uneasy….

X　X　X

The person who’s always kind to Rina (Elena)’s side.

“…Ah, I almost got caught.”

Gasping for breath, Elana quickly disconnected the communication magical device. 

Donned in a luxurious nightgown adorned with beautiful patterns, she murmured to herself.

“Even though he’s a commoner, but he’s strong enough to defeat King Octopus on his own… He’s also the one working hard to pay his little sister’s tuition fees…. Moreover, he’s stronger and smarter than Rina….”

The corner of her lips curled up into a smirk. She had the eyes of a hunter who had finally found her worthy rival. 

“I’m curious to know just how incredible this man really is.”
