Looking up, Damien saw a dark purple sky with five red moons above it. The ground he stepped on was reddish-black. All around were only black trees without leaves.

But even so, his nose smelled fresh air. Even though his ears always heard the roars of sinister beasts.

"Fifth month. This is really the right time.” Amon said after looking at the moons in the sky.

"Fifth month?"

“Here there is no name January, February, March, and so on. There is the first month, second month, third month, and so on. And also in the first month there is only one moon in the sky, in the second month there are two moons in the sky. Now, since there are five moons in the sky, it is the fifth month.”

“Ohh…” Damien gained his first knowledge of the Underworld. "Wouldn't the sky be very beautiful during the twelfth month?"

"That's right." Amon said that now on his hand there is a black liquid floating.

"What is it, Master?" Damien asked while pointing at the black liquid above Amon's hand.

“This is the blood pool of the five Great Demon Kings,”

“What are the Five Great Demon Kings?”

“There have been 665 Demon Kings that have existed, but only five have the title of Great Demon King. It is because during each period of their reign, the Underworld underwent great changes.”

“Who are the five Great Demon Lords?”

“Dark Soul, War Maiden, Rule Breaker, Machina, And lastly is…” Saan Amon wanted to say the last, he puffed out his chest and tilted his head up, and there was an arrogant smile on his face. “Amon the Peace Lover, this Master of yours.”

[Dark Soul, War Maiden, Rule Breaker, Machina, those names all seem cool and domineering. But… what's with Peace Lover?] Damien thought with a stiff face without a smile. [Isn't that too lame?]

“Do you think this title Master of yours seems lame, Bad Boy?” Amon managed to read Damien's mind by looking at his face.

“N-no… of course not.” Damien said while quickly shaking his head. “May I dare to ridicule the great Master?”

"If you think that I suck then get ready to receive punishment from your master!"

“Y-yes!” Damien answered in the affirmative.

"Alright, now it's time to turn you into a demon with this blood." Amon said before shooting five Great Demon King blood at Damien.

“Ack!!” Damien screamed in pain as the blood clot pierced his chest. “Shiiiiit!!”

It was a sickening pain, as if Damien's heart was being eaten away by thousands of ants. And the pain continues to spread throughout the body.

Damien wanted to stop the pain from spreading, but he couldn't. There he could only roll on the ground to endure the pain he received.

“This change will last for an hour. Because of that, I will go first to hunt animals to eat.” Amon said as he casually left. "See you later."

"Wait Master! Help me!" Unfortunately Damien's screams of pain were not heard, because Amon had disappeared. “FUCK!!”

Damien could only bear the pain alone in the end.

When the blood of the five Great Demon Kings entered his head, that was where the real suffering occurred. Starting from dizziness, headaches, to nausea, he felt. Occasionally he would pass out from the pain, but unfortunately he was also awakened by the pain itself.

Finally after an hour, Amon is back.

Amon's right hand was now gripping the black deer's neck. The deer's eyes are blue, and on its head are three horns like drills lined up vertically.

"Are you done, brat?" Ammon said with a pleased grin on his face.

Damien was now lying limp on the ground. His black eyes were now empty without any light of life, as if he was dead. His skin turned pale white, but looked inhuman. His hair, which used to be pink, was now a dark red.

His body looked exhausted like a starving person. But he did not grow the tail, wings and horns, which are the hallmarks of demons. It's just that his ears are now more pointed.

“Are you a Demon?!” Damien shouted angrily at his Master. "How could I leave your student who is in pain."

"I am indeed a demon." Amon said bluntly in a mocking tone.

“Ahh… yes… you are right.”

“Eat this!” Amon said as he threw the black deer he had brought over.

Damien was in a daze for a moment looking at the deer, before asking. “Eating it raw…?”

"Yes."

“Do all the demons eat food that is not cooked first?”

"Of course not. There are things that can be eaten raw without being cooked, there are also things that need to be cooked.” Amon gave information about demons. "After all, in the human world there are also things like this, for example sushi."

"That's true, but it comes from marine animals, not from land animals."

“Don't be fussy, and hurry up and eat!”

“Okay…” Helplessly, Damien ate the deer.

With a look of absolute disgust, Damien took the first bite of the deer's thigh. Damien had thought that the black deer meat would be very tenacious, but it was surprisingly soft to the bite. When the meat was already in his mouth, Damien wanted to swallow it immediately, but suddenly his tongue felt the delicious taste of the meat.

“W-what is this…?” Damien was confused by the pleasure the thing in his mouth produced. “It's… delicious”

"Didn't I already tell you?" Amon said arrogantly. "But don't eat the innards! Bitter taste."

[The meat is very soft. Although eaten without seasoning, this meat has a sweet and sour taste. Besides that, it doesn't have a rancid smell at all, instead it smells like boiled meat. The best thing is the skin, it's very tasty, and also it doesn't have fur at all.]

Damien continued his meal. What's surprising, Damien finished all the meat of the black deer whose body size was bigger than Damien himself.

“This is delicious” Damien said who had just finished eating. "I want more."

“If you want it again then find it yourself.” Amon said that now in his hands there is a book. "But now there's something more important than that."

"What Master?"

“Searching for the Invisible Venom.” While showing a picture in his book.

It was an image of a reddish-purple lizard with a snake's head, six legs, and a scorpion's tail.

"You mean Invisible?"

“Because this lizard has the ability to camouflage. In addition, this animal is very fast, its speed is around 100 km/h. and also the size is only two normal human fingers.”

[Camouflage, 100km/h speed, plus its small size.] “How can I catch it?!”

Never mind capturing, Damien just couldn't imagine how he would find this creature.

“By the Bloodline Ability of the Dark Soul bloodline, Detect Soul.”
