At this moment, Altair, along with Jeanne and Artoria, were in the living room.

After everyone calmed down, Grayfia picked up Rias and teleported out of the room, but what really surprised him was that Sirzechs appeared right away. Seriously, Altair really didn't expect them to have such perfect timing.

Now they are sitting on the sofa, facing each other.

Altair is just waiting for the red-haired man to tell him the reason for his 'visit'.

''What do you want, Sirzechs?'' Inquired Altair to break that silence that was in the room.

"Altair, I would like you to stop my sister's wedding. Sirzechs said going straight to the point, for he knew Altair's personality very well.

''So, they didn't succeed...'' Altair thought not at all surprised, in fact he even expected this result.

''Why?'' Altair inquired.

He was sure that Sirzechs had already made that request to Issei, so what was the point of calling him as well... ''Unless...''

''Her fiancé, Riser Phenex, is a high-level devil, and as if that wasn't enough, he is the heir to the Phenex clan, one of the biggest clans in the underworld.'' Sirzechs said in a tired sigh.

''Go on.'' Altair said with his arms crossed.

''Because of all that power and prestige, he turned out to be the worst kind of scoundrel anyone could know.'' The disgust was noticeable in Sirzechs voice when he talked about Riser.

Altair gave a smile upon hearing those words.

''Interesting... and what do you want me to do?'' Altair asked with an even bigger smile. But who knows if that smile is real?

''Beat Riser and marry my sister, you can surely make her happy...''

Hearing this request from Sirzechs, Altair can't help but raise an eyebrow, he even came to think that Sirzechs was making fun of his face.

''I refuse.'' Obviously Altair denied this request, he didn't even need to think about it.

"B-But why? Sirzechs asked confused by Altair's answer, he knew that anyone who received this proposal would accept it very quickly, but here was Altair refusing it without even thinking about it.

''Nothing against your sister, she is a beautiful girl, however I don't have that kind of feeling for her.'' Altair tried to explain as clearly as possible so that in the future there wouldn't be any kind of misunderstanding.

''I understand...'' Sirzechs murmured in a sad tone.

''But I can still stop her from marrying Riser.''

That sentence from Altair made Sirzechs give a big happy smile, besides he let out a sigh of relief, because he knew that the moment Altair made a move Riser would lose.

''Really?!'' Sirzechs tried to confirm again, for he did not want to see his sister suffer at Riser's hands.

Looking at Sirzechs, Altair let out a small laugh, for even if Sirzechs was the Maou, he still had a good heart.

''Yes, but I have two requests...'' Altair said, causing Sirzechs' attention to focus entirely on him.

''What requests?'' Sirzechs inquired, a little afraid of the requests Altair might make.

''Quickly arrange enrollment for these two girls... And my second request, I want you not to interfere when I steal 'something' from the devils.'' Altair said pointing to the two girls who were in the living room, and when he said the second request he crossed his arms again.

The two girls when they heard Altair's request, their eyes widened.

And Sirzechs was also surprised by the requests, because he remembered that he had promised a while ago that he would enroll the two girls, but due to his intense work he had forgotten this.

''It seems that these two girls are important to him...'' Sirzechs thought with a smile on his face.

But as for Altair's second request, he didn't know what to answer, that's because he didn't know what Altair wanted to steal from the devils, because as far as he knows there is nothing very valuable that a human could be interested in.

''Very well, I will arrange for their enrollment to be done as soon as everything is finished.'' Sirzechs assured as he puffed out his chest.

''As for the second request, I don't know what you can 'steal' from the devils, but I can allow it as long as it doesn't shake the devils' foundations.'' Sirzechs said a little fearfully, but still agreed to the second request, and that just showed how much he appreciated his sister.

''Very well, since I am being paid, I will do an excellent job.'' Altair assured with a muffled laugh at the end.

Sirzechs was thinking about how Altair looked like a mercenary right now, but he didn't care either, as long as his sister could get rid of this marriage it was fine.

''I will leave this paper with my clan's magic circle, just tear it up and you will be teleported to a suitable location.'' As he said this, Sirzechs pulled a paper from his pocket with the symbol of the Gremory clan drawn on it.

''Ok...'' Altair commented keeping the paper in his pocket, he knew he didn't need this item to go to the underworld, but he was still grateful because it could save some mana and also time.

''With that, I'll say goodbye, see you later...'' Sirzechs said goodbye with a smile as his characteristic magic circle surrounded his body.

''See you later.'' Altair said goodbye while waving to the other who just smiled before finally disappearing from the living room.

"So girls... are you ready to ruin an engagement party? Altair inquired with a sarcastic smile on his face as he stood up from the couch.

"Sure, who hasn't ruined an engagement party once in their life? Artoria asked with a sarcasm present in her voice.

''I've never done something like that.'' A confused Jeanne replied. ''Was it normal to destroy marriage? What a strange time.''

"Relax, there's a first time for everything. Altair said giving her a smile and she just nodded, still not really understanding what they were going to do.

"Anyway, why should we ruin Maou's sister's engagement party? Jeanne asked wanting to get that doubt out of her head.

''No... the right question would be... why on earth would Maou himself come here and ask you to ruin his own sister's engagement party? Did anyone see any sense in that?'' Artoria asked.

''If the reason is the brother-in-law, then this guy must really be a parasite...

''Well, he doesn't like his brother-in-law so it makes perfect sense to want to ruin his own sister's engagement.'' Altair replied shrugging at the end.

''That makes a little sense.'' Jeanne commented with a sarcastic tone.

Altair continued talking a little with the girls, until he realized that it was almost time to act, so he decided to go to his room and change clothes, after all this was a 'noble' engagement so he would have to be well dressed.

As he was walking up the stairs, he also warned the two girls to change, as he felt that their clothes were not so suitable for an event of this level.

''Master, how do you intend to make this Riser accept your challenge? After all, he could simply refuse...'' Artoria inquired.

This actually made Altair think for a while, but in the end he just shook his head, and without him noticing an evil smile formed on his face. He had already formed a plan that would have Riser dancing on the palms of his hand.

The two girls who saw their master's smile, had a smile too, for they know that their master would probably be up to something, very, very funny.

''Anyway, I'm going to the room to change, since unlike you, I don't know how to use magic to make clothes...'' Altair said as he went back up the stairs to change his clothes.

The girls just laughed at Altair's comment, since the magic they use really is convenient.

...

...

As Altair was removing the clothes from his body, he ended up thinking whether or not he should make some more preparations. He feels that it will be more fun if he is even more prepared.

He also thought that a new skill to go with his Sacred Gear might go very well in this situation. He even already knew of a skill that would match it perfectly.

And that skill would not seem so predictable to his opponents.

''System, I want you to look for some weapon handling related skill.'' Altair asked mentally as he put on a pair of social pants that would match perfectly with the suit he intended to wear.

[Yes...]

[Skill found!]

*Skill Manual

- Name: Weapon Proficiency

- Rarity: UR

- Price: 4.500 points

[Do you wish to purchase this skill?]

[Yes] [No]

Altair didn't think much about it, and clicked 'Yes'. Something was telling him that this skill would be very useful to him, despite its expensive value...

[The item was moved to his inventory]

After putting on his wine-colored suit, he decided to pick up his skill manual that was now in his inventory, and just like the other times an option appeared.

[Does the host wish to learn this skill?]

[Yes] [No]

Clicking "Yes", it didn't take long for the characteristic window explaining the details of his new skill to appear.

Altair began to read the description of his new skill while looking in the mirror from time to time, just to check if his appearance was at a good level.

[Weapon Proficiency: The user only needs to pick up one weapon before becoming proficient in it instantly. The first time they pick up a sword, they can fight with masters, the first time they use a bow, they can even hit a bull in the eye. Even alien, magical or other weapons they shouldn't understand, the knowledge comes naturally to them]

''A great skill, plus it will go perfectly with my Gate Of Babylon...''

These thoughts ran through his head as he finished fixing his suit, finally he put a high standard watch on his right hand, just to enhance his look.

''Hm... I still feel like there's something missing...'' Altair muttered as he looked in the mirror.

''That's it!'' As he said this, he ran his hand through his red hair, leaving it in a style where it lay more to the right side of his face.

And he had to admit, it was amazing how much more mature his appearance became with just this gesture.

I never thought that one day I would imitate Clark Kent...''

Looking satisfied with his looks, Altair started walking towards the living room, as he didn't want to keep his beautiful servants waiting for so long.

''You took your time...'' Jeanne complained as she glanced at her master's look, and she nodded positively in her head as she saw that her master looked even more handsome.

Jeanne had also changed clothes, and she was now wearing her ornate black armor, with a few chains attached around the pieces that made it up. Her long, black dress lay beneath the armor. Also, on her face was a special helmet that only went around the top of her head.

Artoria on the other hand, who was standing in a corner of the room, was wearing her gothic dress with white details, but this time she was not wearing her armor over the dress.

"Sorry... I was just thinking about some things, and making some preparations for what is going to happen in a little while..." Altair said with a dull smile, as he approached the girls.

Altair was happy today, since he could his servants while also being able to sketch a chicken, he was even thinking if he would fry this chicken when the time came.

''Well, once we are all ready, then let's get going...''

With that sentence, Altair took out the paper he had received from Sirzechs as he activated it so that he could teleport to the underworld, and he had to admit, he was a bit excited, since it would be the first time he would set foot in that place.

''I just hope you can amuse me a little...'' Altair muttered mentally, as he entered the magic circle with his two servants.
