Rin Takahashi is a son born to a poor, unknown mother after an affair with his tyrannical father, that is, an illegitimate relationship, where his father was the womaniser, Ginta Takahashi, and his wife, Yoshida Kawasaki, who hated Rin intensely. Rin had a brother named Kono Takahashi, the older and genius brother who uses the art of sword and water magic at the same time. Time, after the death of Rin's mother, he moved to his father's palace, but he was forced to move to live with them. After time passed, Rin grew up, but he was weak in structure and personality, as he was treated like an outcast. Even when he joined the Kyoto Academy, everyone took advantage of him, but there was a daughter of the Sato family. Her name was Hana. Defending Rin Ae, this is what she was showing him.

Hannah says: Guys, stop hurting him

Bullies The most prominent son of the Suzuki family: Hana-san, why are you defending this weak idiot? Look, he is just trash.

Hannah replies: If you don't stop, I will tell the teachers

Then

Rin fell in love with her, but things turned upside down. She revealed her true face, as she was exploiting him without him knowing her true goal. Hana was familiar with the forbidden methods, that is, rather, the forbidden magic, the magic of summoning the dead in the body of the living, as the summoning book was hidden in Rin's family in the room. Secretly, at the request of the king, Hanna somehow learned about the book, so she approached Ren in order to obtain the book, as she incited the students to beat Ren, while she devised a plan in order to achieve her goal of obtaining the magic of conjuring the dead in a suitable body from one of the sons of the three families, where she discovered that Ren is It was appropriate to sacrifice him. Hannah continued to grow closer to him every day

Hana talks to him: Good morning, Rin-kun, how are you? Rin replies: Good morning, Hana-san.

He began to carry out her requests like a loyal dog. He was not handsome. He was skinny and wore glasses. After two months had passed, the dark day came. She asked him to bring the book, and he agreed to that. She decided to meet her in the Mountain of God. There was a temple inside it, where the story of the Mountain of God was ancient, thousands of years ago, after the ancient battle between the gods. The most powerful demon, Lucifer, was imprisoned in the mountain after his defeat by the six legendary gods and dragons.

Hana says: Rin-kun, do you really love me?

Ren replies: Yes, and he smiles

Hana: Rin-kun, I will ask you something. Will you do it for me?

Rin: Yes, Hana-san, you are the only one I trust. I will do whatever you want

Ren entered the secret room, took the book, and fled from the palace towards the Mountain of God. He was terrified with fear. The students who despised him were waiting for him. Among them was the student Soryun Suzuki and others.

Sorian speaks: Welcome to the weak of the Takahashi family and laughs, guys, look who came.

Rin: What do you want? Where is Hana-san, why are you here?

In the blink of an eye, the book was taken from his hand by the mastermind, Hana Sato

Hana: She says Oh Rin-kun

Rin: Hana-san, what are you doing? What is happening?

Hana: I'm tired of being nice to you, my loyal dog

Ren responds in shock: What?

Then they caught Rin and brought him inside the temple. She was waiting for him in a magic circle made of the blood of six monsters. Hana asked them to chain him in the circle. Rin was shocked by what she did, so she told him that she had tricked him to achieve her goal. She began to read the book in the ancient language with runes. Rin was crying and asking her for help, but to no avail. Feasibility.

Rin: Please, Hana-san, help me. Why is this Hana-san?

Hana replies: Shut up, you are a lab rat for me. You are a descendant of the Takahashi family, and your blood is required for the requested summons.

Rin: Call me what you're talking about, Hana-san

Then Rin remembered that the book could summon the angel or the devil Lucifer.

The magic circle began to glow and swords came out of it and began to stab him to death and then began to swallow him. Rin's last words were Rin: Remember well, I will come back and I will kill you all. Hannah's facial features changed completely after his words, due to the failure of the summoning spell whose goal was to control the winged angel Michael. The temple began to collapse, as did the mountain. Everyone fled and left the book there. They did not know that inside it there was a way to revive Lucifer, as well as a half-god and a half-beast, which is Medusa, who in turn came out. Its power set off an alarm bell in the kingdom, and the king rushed to the place. He, the elite knights, and the king's guards arrived there and found that the temple and the mountain had completely disappeared.

King: What happened? This is impossible. Destroying the mountain and letting that demon Lucifer come out. What a disaster

Leon Squad Leader: Oh King, the Takahashi family is also shocked. The book has disappeared.

King: What did you say? How could this? He was in their secret room.

Golden Falcon Squad Leader: Your Majesty, it seems that their son, Rin Takahashi, was the one who took the book and ran away with it.

The King: We will carry out the necessary and required investigations.

This is the beginning of a great tragedy that will be immortalized in the dark history of the Kingdom of Nihon.

Ren woke up and found himself stabbed and with blood everywhere. He was unable to move. Ren said: Where am I? What is this place? Did you die and go to hell? Then he saw a terrifying monster, rather a huge dragon, which was black in color and had red eyes. Black Dragon Speaks: What human hahaha this is good human food. Rin: What is this terrifying monster? He is terrified. Dragon: Hello, human. What is the son of the damned Takahashi family? Hahaha. This is a wonderful day to take revenge on you. Rin: Don't come near me while he can't move. The dragon was approaching Rin

He was crying, but he saw a sword in front of him. He remembered the betrayal that had happened to him, so he began to move his body little by little until he touched a sword lying on the ground. He picked it up and held it, and began to gather courage and began attacking the dragon. Rin: Ha, that's true. I will never forget the fire of revenge inside me. He attacked repeatedly to no avail every time the dragon hit him with its tail. Dragon: It's no use. You'll die, you weak human. Now I understand, you were the reason Lucifer was freed. Hahaha. How stupid and foolish you are. Rin was silent. In a moment, he saw the dragon's weak point and continued attacking him, but the dragon caught him and said: You were betrayed. What? Hahaha. No, you're just a nobody from the Takahashi family. Strong but you're so weak it's good they got rid of you. Rin grabbed the sword, and in heedlessness, he attacked from the dragon's weak spot until the dragon started screaming in intense pain, while Rin was clinging to him. The dragon's blood splattered on Rin, so he understood that he must change, so he drank the dragon's blood. He began to drink it, and changed partially until his eyes began to resemble the dragon's eyes, red eyes with three stars inside them, Rin. He was not satisfied with that and began to attack. When he noticed that his body had changed and continued to devour the dragon's body, he understood that this monster must be killed in order for it to return more powerful. Dragon: You damned one, I will kill you and started shooting black lightning at Rin. Ren: This is true, from this moment there is no trust. I will never forget what happened to me as long as I live. And now I will kill you and I will become stronger and stronger. He started screaming until the dragon's power began to emerge from Ren's body. Dragon: It is impossible for a human to do that. Hey, who are you? The two clashed with each other until the last breath. After a while, the black dragon was defeated and was unable to move. Dragon: You defeated me, human. What's your name? Rin responded with cold eyes: I am Ivan Muto, the one who will be stronger and stronger. The Dragon. Now you understand Lucifer's last words when he said, "Someone will come who will take all your power from you." Ren inserted his hand into the dragon's heart and ate it, causing his appearance to change completely. His hair became from black to white and his eyes from red to silver. He began to control them as he wished. He could change them from silver to red whenever he wanted. The dragon died and Ren began to eat his body. When he took out all his fangs and began to make two swords. . After he made the two swords, he called them Nodachi and Koto. Then he made a robe for himself from dragon skin, which was black, red, and a little silver.

Ivan began to train and use the two swords as well as the black lightning magic method until he reached the elite stage, when he activated his red eyes, which released a terrifying aura that was noticed by everyone, from kings and knights as well as gods. Then Ivan entered the depths of the mountain and began attacking all the monsters. Monsters speak: This terrifying monster, run away. But to no avail, he killed all the monsters in it, and finally he came out of the mountain and destroyed it completely so that they would not find out about him.
