At this moment Sirzechs was sitting in his office chair in the underworld. His face did not look pleasant at the moment, especially when he remembered what had just happened.

When he went to the human world to visit Altair, he ended up leaving a small magic circle in his house, and this magic circle worked exactly like a bug.

But even he didn't think it would be discovered so easily, and the most shocking thing was that Altair seems to have known about this bug from the beginning.

Sirzechs was a bit disbelieving that Altair had managed to detect his bug, but after thinking for a while he thought it was natural, especially when he remembered the two girls who were always by Altair's side.

''Those two girls, if what he said is true...''

Sirzechs remembered something Altair had said to the girls while explaining to them about this world.

Altair had said that they did not belong to this world, and Sirzechs was shocked by this information, because he knew that there were some people behind the scenes who were madly searching for this other world, even the goal of many of these people was to discover this new world and invade it.

Sirzechs knows that if information like this leaked into the supernatural world, then no one could protect Altair. But Sirzechs has no intention of leaking this into the supernatural world, because he knows that the ones who would suffer the most in this would be the devils.

''Besides... That information about Sacred Gear being able to evolve into Longinus, even I didn't know that, and I doubt Azazel does either...''

In this topic about Sacred Gear, Sirzechs had little or almost no knowledge, and for that reason he was even more shocked, as it was not normal for a human to know so much about it, and another question had been thrown into his mind. How did a human have all this knowledge?

In addition Altair said something that was considered a state secret, the death of the Biblical God. This was information that would not be revealed naturally to people, as the shock could shake an entire faction.

''He participated in the war?!''

Even Sirzechs couldn't believe what he had just said, after all, if a human appeared in the holy war, he would probably be detected easily by any faction, besides the time would not allow this human to live for long.

While thinking about these matters, the red-haired man did not notice his wife approaching his back.

''Sirzechs-sama.'' Grayfia called out to her husband to try to rouse him from his thoughts. And seeing that he had stopped thinking to start facing her, she sighed in relief.

''Thank you for that...'' Sirzechs said with a smile.

''Since you arrived you've been very thoughtful.''

Grayfia commented as she saw the state Sirzechs was in, and she didn't think that was strange, especially when she remembered everything that had happened in that human's house. First he had two bodyguards that had almost the same power as Sirzechs, and that was something impressive, since you have to know that Sirzechs is a power in this world and not many people are able to defeat him.

Moreover, that human possesses a really scary Sacred Gear for devils, after all controlling Sacred Weapons was really something that devils should pay attention to, to avoid suffering losses.

''This kid... he's more dangerous than we imagined.'' Sirzechs said in a serious manner, causing Grayfia to widen her eyes at her husband's speech, it was very rare for her husband to be serious like that.

''We need to be careful with him.'' Sirzechs then sighed for the last time, as he began to prepare the paperwork for the two girls as Altair had asked him to do.

Sirzechs planned to finish this paperwork as soon as possible to show goodwill with the human, and also so that he could better concentrate on the devils business.

...

...

Artoria at this moment was leaving Altair's room. She had come here while following Jeanne to try to calm the poor girl down, but this turned out to be an extremely difficult task, but even though it was difficult, she still managed.

She sighed as she wiped the sweat dripping from her forehead. Looking back, she caught sight of Jeanne lying on the bed, and the sight was a bit strange, as Jeanne was panting a bit, and on top of that, she was naked.

Artoria had used a perfect way to calm someone down.

Putting these thoughts aside, Artoria began to walk towards the kitchen, for a day had passed since she had gone to calm Jeanne down. And right now she was very hungry.

As she reached the kitchen, she noticed that there was a note on the table, and like a curious girl, she picked it up and began to read.

'I'm sorry for not letting you know I was leaving, but I can't be late for school. I may be strong, however, I am a student, and as such, I cannot be absent. And that's it, I'll be there in a few hours, so you can have all the fun you want.

'There's plenty of food in the fridge, signed, Your Master.'

Reading the note, Artoria got a drop on her head.

Her master had a fine reason for leaving them alone. But who was she to judge her master's decisions? So she decided to just focus on the food that was in the fridge, and when she saw how much there was a big smile appeared on her face.

''Master is really thoughtful.'' But Artoria soon after closed the refrigerator, because she still hadn't finished Jeanne's treatment, so jumping for joy while singing a melody, she went back to Altair's room where Jeanne was lying down.

And a short time later, groaning sounds could be heard throughout the house.

A good treat and breakfast indeed.

...

...

It was half-time at the Kuoh school and at one place, or more precisely on the terrace of the school, a person was lying under the terrace floor enjoying the breeze from the wind.

That person was precisely Altair.

He was at this moment remembering something that had happened.

[Quest Alert!]

[Make an alliance with Sirzechs]

- Rewards: 1,500 points, random Sacred Gear.

For Altair this was the type of Quest, that he would complete even if he hadn't shown up, and it's not as you might be thinking, he didn't intend to become a devil or something like that, but rather that he wouldn't want to go to war with the devils, especially when he only had 3 people on his side while the devils had millions?

Another reason, was that after seeing the status of the Maou and his wife, he knew that he couldn't defeat him and would have to rely on his servants to fight, and this was not something he would like to see, since he would become dead weight in the battle and probably be taken hostage, and with that his servants would have to surrender.

He had made all these kinds of considerations before making a decision to make an alliance with Sirzechs.

His God's Eye played a very important role in that encounter.

[Name: Grayfia Lucifuge]

[Lineage: Super Devil]

[Title: Silver Queen]

[Level: 140]

[HP: 50000/50000]

[MP: 800000/800000]

[STR: 600]

[VIT: 500]

[INT: 800]

[DEX: 400]

[LUK: 100]

Grayfia was indeed powerful, and those were just her basic statuses. But what shocked Altair the most were Sirzechs' statuses.

[Name: Sirzechs Lucifer]

[Lineage: Ultimate Devil]

[Title: The Crimson Maou]

[Level: 150]

[HP: 100000/100000]

[MP: 900000/900000]

[STR: 800]

[VIT: 1000]

[INT: 500]

[DEX: 900]

[LUK: 100]

Altair realized that Sirzechs' MP was something out of the ordinary, even he thought Sirzechs could easily spam magic abilities without any problems.

''Damn, if I had a MP like his, I would probably kill my enemies just by spamming fireballs.'' Altair said with a smile on his face, as he imagined the scene of him spamming fireballs an extremely basic magic.

Altair was wondering how Sirzechs could control that huge amount of MP, he with much less than that already had a huge job, so he could hardly imagine if he too had that amount like Sirzechs.

Moreover Sirzechs' level was the highest he had seen since he arrived in this world. But Altair had learned a very important lesson, he should not rely only on these basic statuses.

Especially when these statuses do not show the skills of the target being analyzed.

Altair was sure that Sirzechs status would be at least 3 times higher than what his eyes were showing, and that was completely frightening to imagine.

''I still have a long way to go...''

Altair put his thoughts aside, and decided to check a few things with his system.

''System, show me my skills.'' Altair mentally asked.

[Yes]

[Skills]

- Gate of Babylon lv. 01

- Player Body LV. Max

- Player's Mind lv. Max

- Eye of God LV. Max

- Sensor LV. 07

- Killer Intent lv. 01

- Mana Control lv. 10

- Hwechook lv. 01

- Full Counter lv. 01

- Kai Kai lv. 01

- Gluttony lv. Max

''It seems that since Gluttony cannot be leveled, the skill is treated as max level.'' Altair analyzed this skill, and didn't think that would be bad.

Altair also remembered something, his Hwechook skill. In his fight against Rias, he ended up getting carried away, and misused this skill.

The Hwechook technique, is a kick that gains strength through rapid rotation at a central point. It is a staple of Renewed Taekwondo, as it is used in many variations compared to its ITF Taekwondo counterpart, which focuses on the Flamingo position.

Hwechook hits the opponent like the Roundhouse Kick.

In short, only one kick and not three at once.

That would only be in his 3rd stance.

Hwechook's 3rd Stance is essentially the Hwechook, performed three times in a row.

With this you can already imagine the rebound.

It starts from the left or right, followed immediately in the opposite direction and then from behind. If the victim cringes and tries to run back, the damage increases.

It targets the opponent's brain with the first and second kick, and finishes the opponent with the third. So the rebound from using the third stance was huge for him. He felt his body almost collapse.

If it wasn't for the Player Body.

He must find a way to improve this skill, and fast. And there was only one way now.

''System, where can I find skills related to learning martial arts?'' Altair asked mentally.

[Just ask me, and I will promptly search for you host]

''In this case, look for Renewed Taekwondo.'' Altair asked with a huge smile on his face.

[Yes]

[Looking for...]

[Skill found]

[UR Taekwondo RE skill manual]

- Value: 3,000 points

[Do you wish to purchase this skill?]

[Yes] [No]

Seeing the price of the skill, Altair felt a pain in his heart to spend almost all of his points, because he currently has 3,200 points and by buying this skill he would only have 200 points left that were basically useless.

But he knew that this skill was definitely worth it.

So, even with a pain in his heart, he confirmed the purchase of this skill. And in a few moments the skill ended up in his inventory, but Altair didn't remove it from his inventory immediately, first he used the Sensor to its fullest to see if he was being watched, and upon realizing that he wasn't, he finally removed the skill from his inventory.

[Does the host wish to learn this skill?]

[Yes] [No]

Without wasting much time, Altair mentally pressed 'Yes, and after that the manual, as well as all the others, shattered and then entered his body.

[Congratulations host, you have gained a new skill]

- Renewed Taekwondo(The God of High School): is a type of martial art developed in modern South Korea in The God of High School. It is used by Jin Mo-Ri and Jin Tae-Jin in the series. It is emphasized on strong, linear kicks like its base ITF Taekwondo(North Korean military Taekwondo). Since it is a fighting mode focused on killing, it does not fall under the Taekwondo rules of using only kicks, but also punches and any other means of attack, thus possessing a multitude of strikes.

Seeing the explanation of the skill, Altair's eyes lit up, and if it wasn't for the Player Mind, he probably would have gone around screaming with joy.

Altair is a big fan, or at least was in his life passes of this Manhwa, as he found the fighting insane.

After taking a few breaths to calm down, a notification appeared in front of him.

[As the host acquired Renewed Taekwondo, the Hwechook skill was removed and turned into XP to raise the level of Renewed Taekwondo]

''Huh?'' Altair thought he had heard something wrong.

His skill had just been removed, but he couldn't think for long, because another notification had arrived.

[The Renewed Taekwondo Skill went up from level 01 to level 15]

Altair's eyes widened at this notification, but before he could say anything, his head began to hurt due to the enormous amount of information that was entering his mind.
