Naruto: The Outsider's Resolve - Chapter 3.26 (085):

“Every person has an equal amount of 8 skill holder slots. There are normal skills such as 【Physical Strength】 which takes up 1 slot, but there are also rare skills which take up 4 to 5 slots, or even rarer ones which take up all 8 slots.”

Is what old man Hinga taught me at the Orb Mine, where skill orbs are unearthed.

But we “s*aves” could not acquire skills due to Contract Magic, thus s*aves had no future.

On one fateful day.

The noble who owned the mine, that is, our “Master”, came to visit the Orb Mine.

Due to a sudden earthquake, the ceiling collapsed. Rocks fell directly on the noble’s head. And he died.

At that moment, our contract magic disappeared.

The clever s*aves ran straight to the warehouse where the skill orbs were stored.

They absorbed rare skill orbs, and used their newfound abilities and magic to defeat the guards and escaped the mine.

It was a riot.

I was too late to pick up a skill orb.

“–It’s over. I will be forced back into being a s*ave,” I despaired.

But just then, I saw a skill orb that shouldn’t exist.

An orb which used 10 skill holder slots -【All Things In Creation 《World Ruler》】

A non-standard skill orb that would be of no interest to anyone but researchers because no soul in the world could use it.

However, I was able to absorb 【World Ruler】.

Why? That’s because I was a “reincarnated person.”

I had 8 more skill holder slots than an average person, for a total of 16 slots.

The mine is besieged and there is only one exit. A mysterious skill 【World Ruler】 in my hand.

What do I do now?

An 18-year-old poor college student tried to apply for a job as a tutor but his life almost ended as demons' meal. In his last breath, a mysterious woman gave him a strange power. When he opened his eyes he had turned into a demon with a system that would turn him into… A pervert.

Now he must lived with his dual identity as a model student named Ethan and an incubus named Damian.

“Are you my knight?” The silver-haired youth looked at the blonde girl before him and asked, his cheeks flushed red. This was their first encounter when he was only ten years of age.

“Are you my bride?” He held her in his arms, embraced the girl who had accompanied him for ten years straight. He was sixteen years of age.

“Are you my king?” He knelt before the throne, smiling foolishly as he looked at the girl holding the sword victoriously. At this moment, he looked like the boy he was when they first met.

“I’m fine without having eyes for you. The entirety of Camelot is for your taking.” Smiling soft and gently, he gave his eyes to the girl who lost her eyes due to the curse of the red dragon. He doesn’t regret it, he thinks. He was twenty years of age.

“So… Arthur… Artoria Pendragon, are you willing… are you willing to spend the rest of your life with me?” His voice was soft and clear as he reached out to touch her hand.

This was their legend.

“Pretend to be my lover and join the social circle.”

Selena, the top star that had the entire world’s attention, was suddenly warped to Northern Duke’s land during an accident while filming. Kalcion, the Northern Duke that saved her from the infernal beasts, offers Selena a chance to go back home in return for collecting information in various social circles by pretending to be his lover. Selena quickly accepts Kalcion’s offer, but…

“Why in the world can’t you do this!?”
“Don’t you think that the answer to that should be obvious to you, the actress, not to me, the duke?”

There was a critical problem. The Northern Duke’s acting skills are horrible!

“…Let’s change the plan. I’ll seduce you instead.”

And thus the contractual relationship between the two started. Will Kalcion’s acting skill improve first, or will he start to have true feelings for Selena instead?
