Duke's Quadruplets Are All Overpowered

But what if they find out? What if I was found out that I was someone with the ability to interfere with them, and that I was also an SPY who caused the greatest damage among them? Let’s live in hiding, like a dead mouse. We made a blood oath, so they won’t interfere with my comfortable life. At least until the end of this world.

But after that day, my siblings didn’t let me go.

Gradually regaining the power of their previous lives, they boasted their extraordinaryness and drove me to a situation where it made me rethink of what should I do.
When there was chaos in the family, I realized, the Duchy of Reinberg was not my place. I needed to get out of this world’s most dangerous place right now.

On a cold winter day, I went down to the southern island on the pretext of recuperating from my illness.

Ironically, thanks to the incidental power of ‘Heavenly Sky Eye’, I was also seen as one of the ‘children of the moon’ in the eyes of others. Especially in my father’s eye. With this, it was mistaken as my ‘talent.’ Anyway, I was his precious son, so my request was readily accepted.

However, my father didn’t predict that the child who went down to the southern island because of an illness would imprison himself for four years.

I remain in this island until the age of 14, making up various excuses. However, as soon as I reached the age of 15 to start the full-scale successor education, there were no more excuses.

The more I remembered that day, the stronger my will became.

I looked straight into my father’s eyes and persuaded him again and again.

“Father, please understand the heart of this little one.”

“You have talent.”

“That unknown talent, I will try to bloom it myself on this beautiful island…”

It was then. The Spirit, which had been injected by my father into my body, suddenly heated up, and a rope sprouted from my skin. The rope was around my body in an instant. Damn, was this his intention from the start?

“If you don’t want to go, I will take you by force.”

“But Father!”

“No buts, you are coming with me.”

“The corners of your lips are going up. Don’t try to run away from my hands At least until the coming-of-age ceremony, I will hold you tight and won’t let you go.”

There is no way I can escape from my father’s Spirit by my own strength. I quickly understood the situation.

Okay, let’s wait a few days. Until I seize the opportunity to escape.

***

Duchy of Reinberg, one day after returning to Quilz Castle.

“Young master! The first young master is looking for you!”

“He wouldn’t have find me if you won’t say it!”

“Yes? Are you here?”

“Stupid maid!”

My older brother is looking for me. Not to his room, but to the training ground.

I feel like the empty space between my molars is throbbing.

I got nervous about thinking about what would happen. There are some good points about being ignorant, but there are also many more downsides.

“Then I’ll tell first young master that I couldn’t find you.”

“Wait, Girlie. When brother asked, you will say I went outside .”

“Yes. young master.”

“Haha, girl, you really look like a rabbit.”

“Oh, thank you. Rabbits are cute.”

Rabbits might be smarter.

“Forget it. I will go. Just stay still.”

I will now be facing the guy who defeated knights 4 years ago.

After many years, he might have become more terrifying.

I cleared my mind and got out of bed. I gently pressed both my eyes with my palms in order to relieve eye strain.

In order not to get hurt like last time, I need the power of these eyes. It’s not like I’ve only slept for these past four years. I practiced while looking at the vast sea in ​​the southern island.

If I have this eyes back then, I wouldn’t have an empty space in between my mollars. As long as I have these eyes, I can see all his movements.

There was only one man standing in the wide training ground. Who would see him as a 14-year-old boy? Same age, even twins, but my older brother already looked twice as tall as me. He is becoming a monster.

Having inherited the same blood of the Duke of Reinberg, we are all born with brown eyes and brown hair. Us siblings all certainly looked the same four years ago. But now, it was strange to even call us twins.

Wide shoulders, a thick face line, a face that looks more like a man than a boy. Above else, eyes that resemble the eyes of a lion.

“It’s been a while, Cantavia.”

I walked over to the training ground. After the blood oath, we decided to go back to being brothers and sisters as before. So he called me brother and Cantavia, and I called him brother and Ranista.

“Ranista hyung.”

“Raise your weapon.”

I stopped walking.

“… Why?”

I took a step back

“I will teach you martial arts.”

I should have run away last night.
