Damien was now sitting in the staff room after Lucius brought him here. He is currently filling out his registration form.

"Master, here... I was ordered to fill in such as residence and parents?" Damien said in a very low voice.

"Just leave it blank, don't write anything." Luckily Amon's voice was only heard by Damien.

“…Is that really okay?”

"It doesn't matter."

Lucius finally came back carrying a jar. "Put the lizard in this jar?"

"Isn't that animal abuse?"

“That Invisible Venom can't die if his head isn't crushed, Fool.”

[Why do these people like to call me Fool?] Of course Damien was not offended, as he had faced many people rougher than this. "I'm Damien."

Damien introduced himself before stuffing the Invisible Venom into the jar Lucius had brought him.

“Lucius,” He happily accepted the introduction. “Lucius of the Lucifer family, Fool.”

[Still calling me Fool.]

"This is your uniform." Lucius said as he snapped his fingers before appearing three identical black formal coats. “In this Academy there is only one uniform, which is just this coat."

"For the other clothes?"

"Up to you."

[This academy seems to support students' freedom of dress.]

“Tomorrow is the day of the New Student Acceptance Ceremony, the ceremony starts at eight in the morning. Do not be late." Lucius informs the School events.

"Okay."

"You may go now."

Damien left the staff room and left Lucius who was chasing his co-workers.

“New Irregular?” asked Lucius' co-worker.

"Yes."

“Isn't he an extraordinary child. can write the registration form without losing focus on maintaining the magic.” The teacher praised Damien. “There aren't many devils his age who have such good abilities.”

"But, look at this!" Lucius said while handing Damien the registration form. " Everything about his background is not filled in."

"Looks like we'll have to do another investigation for the Irregular student."

Damien who was now in front of the Academy gates was confused.

"Now what should I do?" Damien didn't have a home to return to in the Demon World.

"Enter into the forest, Because there is a technique that this King wishes to give you."

“Ohh!” Damien was excited to hear that, because it meant he would be strong again soon. "What is master?"

"Just go first."

"Okay." Damien said as he quickly ran into the depths of the forest.

Damien stopped at a waterfall that was deep in the forest near Dagon Academy.

“The technique I've given the name to is the Blood Sacrifice. It is a technique that allows you to transform your entire bloodline into a pure Satan Bloodline. By sacrificing the other bloodlines in your body.”

"Why?!" Damien screamed in displeasure at that. “The other bloodlines are strong too, why should I sacrifice them?”

[One black arm alone is capable of uprooting a large tree, wouldn't if I could control a hundred of them then I 'd be very strong?] Damien felt reluctant to follow his teacher's instructions. [After all, if the Dark Hand of the Dark Soul bloodline is powerful, isn't the Bloodline Ability of the other bloodlines powerful? Why should I sacrifice them.]

“You fool, if you sacrifice another bloodline, then you will gain Satan's power that surpasses that of the five Great Demon Lords.”

Hearing that, Damien felt tempted. "Are you serious, Master?"

"I'm serious."

"Then I will!" Damien's spirited voice.

"This is the technique."

The ring that was being occupied by Amon shone, suddenly an information entered Damien's mind just like that. This was the effect magic that Amon used, magic capable of giving the target the form of information.

The information that Amon gave was very much, deep, and complicated. But because Amon was a powerful demon, the information was received by Damien flawlessly and smoothly. Even that information was seared into Damien's memory.

“It's a technique apparently done in meditation…” Damien said after receiving the information about the Blood Sacrifice.

The way this technique works is actually quite simple. The user only needs to restrain the blood of a lineage in the heart, and infuse Demonic Energy into the heart. After that it was only necessary to wait until the sacrifice was over.

It looks trivial, but the process is very complicated. Because Damien needed to find the Blood he wanted to sacrifice from the seven bloodlines he possessed.

In addition, if there is an error in the process, the impact will be fatal. Just a trivial mistake, it can make heart failure. And the worst can make the heart explode.

“First you must sacrifice your human bloodline!”

“Eh… I still have the Human bloodline?” Damien thought he had completely become a demon.

"Of course. And this is just a warning, if even one drop of blood comes out of your body, then you can be recognized as a human and you will be hunted as food.”

"Seriously?!!" Damien screamed in fear.

“Besides that, you will also be recognized as a devil who has the bloodline of the five great Demon Kings. And I will be hunted to extract your blood."

“…That's so scary.” Damien's body shook with fear thinking of the future if he made a mistake.

"Bringing great power comes with great risks, brat." Ammon advised him. “That's why you have to be careful in every battle you do so you don't get hurt.”

“… Okay.”

“Now, perform the Blood Sacrifice!”

Morning has come.

Damien, who had just finished bathing in the waterfall, now wanted to wear his school uniform. With the clothes he brought into this world and the uniform he received yesterday, Damien left for the Academy.
