I apologized to the teacher and explained why I couldn't come to school. The teacher welcomed me warmly, introduced me to the class, and then told me that they had already gone through the basics of magic. Today, they were teaching us how to summon a familiar (like an assistant or a secretary). So, she needed to be sure that I knew all the basics. At that moment, I remembered what my father had said: "Don't show your light magic to anyone."
So, I showed them a "small" fire magic spell (a ball of fire appeared in my hand). The teacher liked it and said that I was ready to summon a familiar. She also gave me a paper with the school rules. I looked at it, and the first rule stated that your race and social status don't matter, and everyone is equal. I was happy when I read that and didn't even read the others.
The teacher wrote a spell on the blackboard and handed out papers on which to draw a spell circle.
Teacher - Now imagine what type of familiar you want, read the spell script from the board, and cast your magic into the circle that you have on the tables.
Everyone's paper ripped, and dog-sized monsters appeared.
Teacher - Congratulations, now give them names, and the contract will be complete. They will become your familiars.
Suddenly, she came to me.
Teacher - Something isn't working for you. Put more mana into the paper.
I let in a little more mana, and my paper ripped, but the familiar didn't appear. My body started to glow, and I got a terrible feeling. This glow came out of me and dove into the paper parts. Suddenly, in front of me, the son of the ruler of demons spawned. The ground shook during his appearance, lightning struck everywhere, and everyone panicked. When he finally appeared, we saw that he was wearing large heavy handcuffs, a black suit, and had two horns on top of his head. The teacher was exhausted from fear, but she still managed to say:
Teacher - Runn... he's the prince of demons!
Suddenly, I got an idea. If everyone is so afraid of him, then I will make him my familiar. He will protect me both by force and by name.
Uta - Teacher, how should I sign the contra...
Demon - Contract, you say? (He grew angrier and angrier) Die, unknown creature!
He began to recite a killing spell. At that moment, the teacher used telepathy magic to tell me what I should do to make him my familiar, though it shouldn't have worked. I started reading the spell the teacher had told me and gathered all my mana in my chest. The teacher put an air magic shield on me, and I was ready to approach him.
As soon as I got close to him, he canceled the magic, and his clawed hand pierced my heart. At that moment, as I fell to my knees, I remembered my fiancée from my previous life, and I blacked out before I could cast my spell on him.
I woke up a few hours later. At that moment, I checked my chest, and there was no hole. The school doctor examined me and said that there was nothing wrong with me. At the same time, the teacher and classmates came into the room and told me what happened after he killed me.
"Demon - Did she really want to make a contract so badly that she sacrificed herself for it? I don't understand how you humans can be so stupid, but this girl interests me... Hey, you're her teacher, right? When she wakes up, tell her to perform the summoning ritual again. I want to talk to her.
Teacher - And then he healed your wound and disappeared in black smoke."
As soon as I went outside, I did the summoning ritual again, and everything happened just like before, lightning and all. But this time, he no longer had the intention of killing me, nor was he wearing the handcuffs. He walked up to me and spoke:
Demon - You could have easily blocked that attack as well as my knockout move. I understood this when I touched your heart. You have infinite power, but why... I don't understand, are you stupid?
(The teacher was shocked.)
My answer was - I like you. For a moment, the demon's face turned red, and he asked me in a low voice who I was thinking of at the moment of my death. I told him that it was a secret.
Demon - (Cough) I agree to make a contract with you, but I have one condition, you must fulfill one wish of mine in the future.
I agreed to his condition. At that time, the demon told me to choose a name for him. I didn't think too much about it and said, "Diablo-Dia for short." The contract was completed (the contract breaker dies both physically and spiritually).
Dia - I'm excited about my new name, my lady.
Uta - You don't need to call me that. Let's be friends. (She reached her hand out for a handshake.)
Diablo was embarrassed and lowered his hand. When everything calmed down, the lessons resumed, and the students grew stronger with the help of the teachers.
After 4 years (Meanwhile, Uta has reached her power limit at age 10):
I was a mess. Even when I used a little magic, the results were disastrous. I couldn't control my power anymore, and the teachers noticed this and told me to leave school to protect the other students.
I thought a lot about this, and I even asked Dia for advice. He also advised me to leave school and go to his father, the Demon King. He said that his father could use magic that would increase other people's magic capacity. I liked this idea and decided to try it, and since Dia would be by my side, no one would dare to come near me. Dia told me that he could open a teleportation gate to the demon land at any time, so I warned everyone that I was going to be gone for a long time. My family at home accepted this news easily, though I did not tell them that we were going to the land of demons. Finally, I asked Dia to open the gate, and we crossed into the land of demons.
As soon as we arrived, we found ourselves surrounded by millions of demons. At that moment, the Demon King stepped forward.
Demon King - Is that you?
Diablo - Hey Dad, it's me. Sorry I couldn't contact you for so long.
Demon King - I thought the humans killed you, and I was planning to destroy them with this army.
Diablo - Father, I came to beg you. (He kneeled.) This is my master. (Pointing at Uta.) And I became her familiar.
Demon King - How dare you enslave my son! I will kill y...
Diablo - Father, stop! I'm not a slave. In fact, I submitted to her of my own free will, so relax. She could have killed me at any moment, but instead, she accepted me. She doesn't see me like others do, and she doesn't view me as just a demon.
Demon King - Do you...
Diablo - Yes, Father, and please don't say any more. (He looked embarrassed.)
Demon King - Well, what do you want to ask?
Diablo - She has reached the limits of her power and can use light magic. I brought her to you, hoping you would use your magic to help her exceed her limits.
Demon King - Is that all? (Laughs.) (He addresses the demons:) Disperse! There won't be any more war, we will have a big party this evening.
I looked around in surprise. I had always imagined demons as evil, based on books and people's stories, but they were no less human than us. Until we reached the palace, I saw many beautiful things that I had never seen before. Damn, I thanked my fate that Dia appeared to me back then. The Demon King told me that before the feast, he would increase my maximum power capacity. He led me to a large hall where a large circle was drawn on the floor. He told me to stand in the center of the circle, and the spell began. He recited the spell for five minutes before the circle started to glow and then went out. I felt that something had changed within me.
Demon King - You will feel the deep changes later, after sleeping.
I thanked the king, and he led me to the feast. On the way, he told me that if I reached the power limit again, he wouldn't be able to help, and I would likely kill myself or others.
But I didn't pay much attention to that. I had a great time that night; I only drank the juice, which was very tasty. The next day, everyone had a headache. We said goodbye to the king, Dia opened the portal, and we returned home.
