Underworld

When they arrived in the Underworld, he realized that they sent him alone, he knew they would not take him near Gremory territory and he did not ask for help, it was normal that they did not come with him.

So he did not care much and started looking around, he was close to what looked like a forest, with his [Magical perception] he could feel everything around him, so he started walking in the forest, it was common if you wanted to investigate, you would do it away from the others, so he wanted to go to an isolated place.

He had already activated his [Presence] and suppressed his aura, most likely only a few knew that he was here, he just hoped that Lucifer had already spoken to others.

Yukio: (System, is there no way to find them?)

System [Since the spells are sealed, it is impossible to help you]

Yukio: (When can I use the spells?)

System [You have to meet the requirements by default].

Yukio: (I understand ... Is there any ability to improve the search?)

System [Analyzing ....]

He searched all the corners of the forest for a few hours, with the help of [Magical Perception] he could feel even the smallest insects, but he made sure to look for them himself, he did not want to make mistakes anymore. He was a little tired until the system spoke again.

System [Full analysis]

System [No useful skills found]

Yukio: "...."

He was speechless, it spent about four hours analyzing only to find nothing, he felt he had to hit it, but it was impossible, at least he could see in the dark, he did not know if it was because of his strength or because his eyes came from a dragon.

Yukio: "Whatever ... Let's continue ..." While he observed, if he saw any beast or something, he always attacked them, he did not mind fighting because it was something satisfactory, also he got experience and improved his statistics. They increased the more he killed.

--- The Gremorys.

Sirzechs: "What exactly is he looking for on this site?"

Grayfia: "I don't know, he just told me that he wanted to meet someone and didn't give me any more explanations."

Sirzechs: "Looking for someone? Does he know someone from the underworld?" He rubbed his chin as he thought. "Rias, do you know something?"

Rías: "No... I had asked him, but he would only avoid talking about it."

Sirzechs sighed heavily as he watched Yukio from a distance who was killing everything in his path.

Sirzechs: "For now let's see how everything goes..." Everyone nodded and stared at Yukio.

--- Yukio

He had already spent almost a day in this meaningless search, the only good thing was that he could get a lot of battle experience in this site, at this moment he was on a tree eating part of a demon that he had roasted, he actually thought it would be disgusting but it was not.

He had asked the system why and its answer was the same one as he thought.

System: [The user has the genes of a dragon, the human metabolism does not exist in you.]

This made him understand that his body was changing and that the worst thing was, he was feeling very hungry and had to go through many demons, most likely the portion of food at home would not satisfy him anymore.

Yukio: "How would I tell my parents? Puberty? Impossible I am only seven..."

--- The Gremorys

There was a momentary silence until Sirzechs broke it.

Sirzechs: "Is he eating the demons?"

Grayfia: "I think so ... Maybe he's very hungry?" They were both in confusion, they have seen many things, but a person who ate demons was new to both.

Rías: "Is he an idiot? At least he should have brought food ..."

--- Yukio

While he was eating, he wanted to take a bottle of water from his inventory, but then he stopped, he knew they would be watching him, he didn't want to expose that he could make things appear suddenly, so he jumped out of the tree to drink some water from a nearby lake.

He thought about it a bit and decided to bathe, from the moment he arrived here, he walked and fought, he was full of dirt and blood, so he stayed in his underwear and went into the water, relaxed until the system spoke.

System: [The user is one step away from waking up another 1% of his bloodline, it is recommended to be in an isolated place.]

He raised an eyebrow to its comment (Why an isolated place? The previous times it was not like that.)

System: [You will awaken 10% of the blood, your body will change at an abnormal rate and you will be in a weak state for a few hours; you will be notified when the awakening will be after two days].

He relaxed a little knowing that it will be in two days, he still had time to continue searching in the Underworld, he left the lake and dressed up quickly, he needed to accelerate his search, therefore, he jumped over the trees.

--- Two days had passed

Tomorrow would be when his blood will wake up to 10% and he was a little dispirited.

He could not find any trace of nekomatas in his quest, he found many beasts and sometimes villages that he did not even know existed, he wanted to investigate but did not have time.

He was eating parts of demons while thinking about the best way to find the sisters quickly, he really did not remember when Kuroka would kill her teacher, he was probably too early but it was for the best.

Yukio: "Maybe ... I should have asked them for help." He rubbed his forehead wondering what to do when suddenly "Presences? 2,5,7,30 Isn't that a lot?"

He felt many presences when they entered the range of his [Magic Perception]. He could feel twenty-eight Low Rank, while the last two were Medium Rank, he was a little interested ...

He quickly swallowed the food and started running through the trees to see the nearby presences, he wanted to know why there were so many people in a place like this.

--- The Gremorys.

Grayfia: "What's going on?" She could see Sirzechs frown suddenly.

Sirzechs: "I feel the presence of someone I know, but I don't understand why Yukio goes to them."

Rías: "Is it dangerous? Onii-sama."

Sirzechs noticed the concern of his little sister and smiled: "No, I do not think there are any problems, if something happens I will solve it."

Rias felt better when she heard those words and continued to look at Yukio as he was moving away in the distance.

Sirzechs: "Let´s go." So the three went to the presences to see what Yukio would do.

--- Yukio

When he arrived he could see many demons running frantically, he saw a big man who gave the orders, he could feel his mid-rank aura but determined that he was at the intermediate level.

???: "Search the whole forest, do not let them escape! NOW!"

Demons: "HAI !!"

He saw how they were dispersing, he noticed that there were twenty-eight demons here, but they were supposed to be thirty, he felt two more very far away.

Yukio: "Are those two the ones they are looking for?" His curiosity continued to go down, after all, all of them barely had a low rank, even though there were many searching for them, maybe they would be prisoners.

Even so, he ran to the two presences, at least he wanted to know who they were for them to be persecuted.

It took a little time, but finally, he arrived in front of a cave where he felt the two presences, their auras were very weak, he assumed they were injured while fighting.

He moved inside the cave and had [Presence] activated, they would not notice him even if he was in front of them.

When he approached he noticed two figures, they were hugging and had wounds. Throughout their bodies, the vital energy of the two people slowly got lower.

One of them was unconscious, but the other was crying and blood could be seen in all her clothes, he was so petrified that without realizing, his [Presence] had been deactivated, revealing himself to this person.

???: "Leave us! No more!" She implored with tears in her eyes. From that it was understandable that she had barely managed to escape and now that she had too many wounds, it was impossible to do it again when she had to carry an unconscious person in her arms, but no matter how much she implored she received no response from Yukio.

His body felt hot and in his head, came thousands of thoughts when seeing this person in front of him, he could not move his body and he felt as if had been shut off for a few moments when a name came out of his mouth.

Yukio: "Kuroka ..."

--- The Gremory

They were watching what was happening inside the cave with a crystal ball that allowed to see everything, they realized that Yukio was frozen, and they did not understand why, but then they heard that he said a name.

Sirzechs: "The connection between ..." His sentence was not finished when an aura, that stretched from inside the cave was frightening, it was not the mid-rank aura, it was something they did not even know how to describe. The nearby trees swayed as if they were going to break.

Within the aura you could feel the malice, the whole area was under the pressure caused by the dragon aura.

Grayfia: "This feeling ..."

Sirzechs: "It's anger." Simple words, but they described everything that was felt from the aura, they already knew that others would come now and it would very possibly end badly.

--- Yukio

His anger shot up but he quickly repressed it, he had to cure Kuroka or she could die, he got closer and could see that she was in poor condition.

Yukio: "I'm sorry, please take this, it will help you recover", he handed her a healing pill, but Kuroka did not take it, she looked him in the eyes and spoke.

Kuroka: "Who are you? How do you know me? "She had heard him say her name.

He really did not know how to tell her, that's why he had to think up something quickly.

Yukio: "I promised a person that I would protect you, this is not the time to talk, swallow the pill."

Kuroka ignored the pill and asked again "Who did you promise to protect us? Do you think I'm an idiot?"

-Shit, it´s hard to deal with hardheaded women- He sighed and took the pill from her hands and then he put it in her mouth since she was weak, she could not stop him and ended up swallowing it.

Kuroka "* Cough *" She kept coughing "D-damn! What was that pill? "She hugged her sister tightly trying to lean back, but felt something warm on her abdomen and soon her wounds were healing quickly.

Yukio: "See? It's just a pill that serves to heal you, to whom I promised to protect you is not important now, we must leave before they come for you."

Kuroka hesitated a moment but got up while carrying Shirone who was unconscious, she looked at her and then fixed her gaze on him.

Yukio: "I know what you want, but it's better to get away fast, it'll be fine soon." He handed her another pill. "When she wakes up, you'll give her this."

They left the cave, he felt many presences approaching, so he took Shirone in his arms like a princess "We're going that way, I feel a lot of people coming from the front."

Kuroka did not want to let him take Shirone, but it was not the time for a meaningless fight, so she followed him though she kept watching every one of his movements.

---

They ran for a few hours, on the road none of them spoke and soon they arrived near a lake.

He wanted them to enter his dimension, but after thinking a bit, he decided better not to, he did not know how they would react, during the trip Shirone had awakened, but to his surprise, she did not attack him. -That's good.-

He sat near the lake, he felt that the presences were disappearing, but not because they left his range, he knew that something must be happening, when he was immersed in his thoughts, Kuroka came to his side.

Kuroka: "Can we talk?"

Yukio: "What's wrong?" He saw her look, he assumed she would have something to ask.

Kuroka: "Why did you lie that someone asked you to protect us?"

He was not surprised, this girl was very intelligent. Who would even ask to protect them? When her mother died many years ago and her father was demented.

Yukio: "Who said I lied?" He smiled "I promised myself to protect you Kuroka."

Kuroka did not expect him to respond in that way, so she blushed a little, but was still on guard in case he tried to attack her.

Kuroka: "What exactly are you planning?"

Yukio: "Nothing, I just want to protect you. Am I doing something wrong?"

Kuroka frowned but still asked what mattered most to her "How did you know my name?"

He got up to stretch and look her in the eye. "Would you believe me if I told you that I saw you in my dreams?"

He left her alone before she kept asking, he went to a tree where he went to bed. He was tired of running so much, he saw Kuroka looking at him from afar, but closed his eyes ignoring her ...

Kuroka: "Do you think I'm going to believe that lie?" She snorted and approached her sleeping sister, turning to look at Yukio "But if you save us, I would not mind believing in you …"
