Reborn: I'm A Dragon Girl With An OP System

Since I knew everyone wanted to see what I was about to do, I made sure everyone stood back while I covered them in a five layered barrier just in case. I walked to the far side of the boss room to get as far away as possible before taking a deep breath and opening my skill menu.

[Summon Demon(LVL 1)]

“Hmm? So it’s not maxed out?” I pondered for a moment and looked at the upgrade requirements. “Ten points per…. Currently, I have 135 Skill Points…. I wonder if the level of the summon relates to how strong the demon is?”

If I were to think of it like this. If I were to summon a demon now, it would probably be some kind of small imp with a frail body. But if I were to max it out, would I be able to handle what came? This was a bit of a problem. I did not wish to end up summoning something I could not handle. But…. “Appraisal….”  I decided to try to use appraisal on the skill to see if it would give me more information.

[Summon Demon: Skill Level 1]

[When summoning a demon, one must have the proper supply of mana available. While mana is important, the level of a demon summoned will be locked based on skill level.]

[Skill Level 1: demon level 1-10]_.

[Skill Level 2: demon level 10-30]

[Skill Level 3: demon level 30-70]

[Skill Level 4: demon level 70-120]

[Skill Level 5: demon level 120-250]

[Skill Level 6: demon level 250-470]

[Skill Level 7: demon level 470-780]

[Skill Level 8: demon level 780-1500]

[Skill Level 9: demon level 1500-6000]

[Skill Level 10: demon level 6000-???????]

My eyes almost popped out of my head. What the hell are the levels!? Level 10 even had a bunch of question marks! I knew for sure it would be bad to summon such a demon. So I decided to only up my skill to level  5. It was basically the same level range as me. At least, I hope….

Taking a deep breath, I stood with my hand stretched out and said: “Summon Demon!” A large purple magic circle formed in front of me. Small bands of light rose up off of it. I stood there and waited for the demon to appear. And waited…. And waited….

[Mana Disturbance Detected…]

[Skill Summon Demon: Forcefully upgraded to Level 10]

ɴ[0)ᴠᴇʟ [Restriction countermeasures implemented….]

[Skill: Summon Demon, forcefully changed to Skill: Enslave Demon.]

[No matter the level of demon to appear, it will now be enslaved by host….]

The purple magic circle that was now summoning a demon beyond anything I could ever imagine suddenly began to pulsate, and long purple chains shot forward as a cloud of black smoke formed in the center of the magic circle. “Haha! I am finally fre…. Wait! What the hell is this!? Get off me!? Damnit!”

A voice came from within the black smoke. It slowly began to dissipate before finally revealing a young man that looked around twenty years of age. He had short black hair cut neatly, wearing a black suit. He had two horns growing out of the top of his head and a long thin black pointy tail coming out of his backside. A set of the black bat like wings sprouted from his back.

But the look on his face said one thing. And that was that he was not a happy demon. He turned his red eyes towards me with a sullen face before slowly bowing his head towards me. “Master….”

“Umm…” I scratched my head. “I have to ask, but did you try to force your way through the summoning?”

The demon in front of me’s body stiffened as he nodded his head. “I felt a source of mana that was irresistible and followed it…. But now…. I did not really think Master would be so strong.”

“I see… Then can I at least know your name? Mine is Faith Cyrilia.” I asked as I introduced myself.

“I am Diablo. One of the seven kings of hell, The First King of Hell.” Diablo replied as he bowed. “It is an honor to serve such a powerful master….”

“Ummm…” I bit my lip. He would figure it out sooner rather than later, but I figure it would be best to just lay it out there. “I am not as strong as you.”

“What?  Nonsense!? How else would you…. No, you are right but…. This is impossible!” Diablo’s eyes went wide with shock as he looked at me. He walked out of the magic circle and began looking me over while holding his chin. “You… I see…. I see… Hahahahah! How lucky can I be! While it is strange that you were able to enslave me, I do find you quite interesting. Not a single drip of mana that I am consuming seems to affect you at all. Hahahaha! I have found a very interesting Master! I have decided!”

I watched as Diablo suddenly knelt down on one knee before me with one hand on the ground and the other on his chest as he bowed to me. “I, Diablo, one of the Seven Kings of Hell from this day forth, will bind myself to Master, Faith Cyrilia and will listen to her orders unconditionally.”

As soon as Diablo finished saying these words, a large magic circle spread out under the both of us.

[Servant System Now Unlocked]

[Diablo has become your loyal servant.]

I stared at the message in front of me. With a blank expression, I mean, come on! Why is everything being forced!? I sighed as I looked up at Diablo. “Why are you doing this?”

“Why? Because to us demons, mana is our food and source of power. You have an unlimited supply. While weak, you are worth following in order to grow stronger. Do not worry. With the master servant contract, I can not disobey your words or risk being erased from existence, and I do not wish for that to happen. The enslavement you put upon me before still allowed me to go against some of your commands but now…. Now I am one hundred percent under your command.”
