Rias who had not felt anything wrong, had a funny expression on her face, since she never knew that Grayfia knew Altair.

''Since when do you two know each other?'' Rias asked curiously. And she wasn't the only one who was curious.

''Me and your brother, we went to his apartment.''

Grayfia said as she sighed, because she saw the reaction everyone had at the moment.

''Kiba...'' Issei nudged Kiba to get the blonde's attention.

''Yes Issei-kun?'' Inquired Kiba, looking curious at his friend.

''Who is this woman and who is buchou's brother?'' Issei asked not hiding his curiosity to know more about Rias, the person he admired the most.

''That woman is the most powerful Queen of the underworld.'' Kiba explained while covered in seriousness as he talked about Grayfia.

''Wow! And who is buchou's brother?'' Issei was now even more curious to know the identity of Rias' brother.

''The Maou!'' Kiba answered bluntly, earning Issei's shocked look.

''IS WHAT?!'' Issei shouted in surprise, drawing the gazes of everyone in the room to him, the same blushed and cowered in his corner.

Even though this side conversation was going on, Rias still continued to question Grayfia.

"What do you mean you went to his apartment? Rias was now indignant as she looked at Grayfia.

''Altair you bastard, welcoming a beauty like that into your home.'' Issei said with a closed fist as anime tears flowed from his eyes.

Everyone except Altair had a black expression upon hearing what Issei had just said.

''Isn't this boy afraid to die?'' Riser thought mentally as he looked with contempt at Issei who was crying in a corner.

Altair just sighed at Issei's speech. To Altair, Issei this pervert was completely predictable.

''Well...'' Grayfia had a drop on her head and coughed a little to regain her composure, as this sentence from Issei made her a little bewildered.

''We went to invite you to become part of our faction.'' She said making everyone look at Altair who was still devouring the candy in a relaxed manner, he even stole the rest of Koneko's candy, not leaving behind even the fish-shaped candy she was eating.

''Why would you personally invite this pig?'' Riser asked in an obvious tone of contempt in his voice.

''Riser-sama, I suggest you don't talk about him like that.'' Grayfia said in a warning tone while looking coldly at Riser.

''Yes.'' He muttered as he agreed.

It was humiliating for Riser to be so obedient, even with his own parents he was not obedient, but here he was obeying a maid.

But in truth, Riser had misinterpreted Grayfia's words, she didn't want him to speak in that tone with Altair, because she was afraid that Altair would kill him. And that would be tragic to say the least.

''But he's not a devil... So he refused?'' Akeno asked confused, because she could sense that Altair was still a human.

''No... I accepted.'' Altair sneered in his mind.

That was as obvious as saying that Jeanne was the best girl.

Wait...

''Artoria is not far behind, in fact she... She's a great girl too...''

''And now? Fuck...''

Altair doesn't know who to choose!

So, Altair started focusing on this 'philosophical' subject, while completely ignoring their conversation.

''Yes, he refused...'' Grayfia replied with a sigh. Even she didn't understand why Altair refused to join them, after all, she herself saw no disadvantage, and only benefits in becoming a devil.

''Altair, why don't you want to be a devil?'' Rias asked confused, as she looked at Altair who seemed to be focused on other things.

For Rias, if his brother went to Altair, then he probably had the opportunity to make a nobility, that is basically a harem. And most men only use the parts on women for that.

However, she waited for a while for Altair's answer, but she tended to be disappointed since no answer came to her question.

After a few seconds, Altair finally woke up from his thoughts, and realized that everyone was looking at him now, and they seemed to be expecting something from him.

''What?'' He asked coldly.

''Altair, did you pay attention to the question I asked you?'' Rias spoke with a pulsing vein in her forehead. She was already getting impatient.

"Huh? No...'' He replied, as he looked away.

With that answer, Rias became even more irritated, she doesn't like being ignored after all.

''He doesn't want to abandon his humanity.''

The one who answered Rias' question, turned out to be Grayfia who couldn't stand this situation anymore either, besides she was afraid that Rias would only make their relationship worse.

''Hmph, pathetic.'' Riser snorted attracting everyone's attention.

''What's so great about being a human?'' He continued saying while keeping a look of contempt on his face.

These words from Riser caused Altair to pay a little more attention to Riser.

''Humans are just trash.'' Riser said with a sneering smile.

Rias and her nobility's eyes widened at this sentence from Riser, after all this was a bit similar to the scene of her talking to Altair for the first time where right after the conversation, she fought Altair and was defeated pathetically.

Grayfia wasn't liking the direction of that conversation either.

''They are frail and weak... Humans only serve to become slaves to us devils...''

Riser continued talking about how fragile and useless humans were, and it seemed that he didn't notice the looks everyone was giving him.

''Slaves... I imagined it would be like this...'' Altair thought vaguely.

''Riser! How can you say that?! Rias asked in surprise at the blond's audacity to say things like that in front of a human. In his head Rias thought about how idiotic Riser was for not being able to read the situation, after all a person who could talk quietly with Grayfia would definitely not be an ordinary person.

But before Riser could answer Rias' question, he felt a sword go through his stomach. And the next thing he knew he was already spitting blood.

''ONII-SAMA!'' Ravel shouted in shock.

''RISER-SAMA!'' Riser's servants also shouted in shock.

Moments later, the sword that was stuck in Riser's stomach disappeared, causing him to fall to his knees because of the enormous pain he was feeling at the moment.

''I'm not regenerating... Is that a holy sword?'' Riser thought in panic as he saw that his wound was not regenerating, in addition he began to feel a huge burning sensation causing him to panic even more.

This just showed how weak Riser's mental state was, he could not think clearly after suffering an adversity, and now he had to suffer the consequences of his actions.

Altair just stood by and watched as Riser's servants tried in vain to stop his bleeding. Until Ravel recovered from the shock and went to his brother giving him a Tear of the Phoenix.

Ravel was crying with concern as he saw how Riser was writhing and screaming in pain at the same time after recovering from his injury.

''So...'' Altair lightly tapped his palm drawing everyone's attention.

''What was it like to be between life and death?''

Altair asked this question with a sneering smile, to him it was funny that someone who claimed to be immortal was panicking a few seconds ago over his possible death.

''DEAD!'' Ravel shouted in hatred as he cast a fire magic towards Altair. This magic that Ravel cast would not explode when it hit Altair, but would instead slowly burn him to death. And she was even happier when she realized that Altair did not intend to dodge her attack.

Altair seeing this attack coming his way just sighed. ''They don't learn.'' He thought.

Full Counter...'' He muttered, and with a wave of his hand, made the attack come back towards Ravel. Only this time the attack was twice as big and more powerful.

Ravel's eyes widened when she saw that her attack was coming back at her, plus her attack now seemed much stronger than when she had launched it to attack Altair.

She also realized that she would not be able to deflect or defend herself from this attack, all she could do was watch as she would be hit and probably seriously injured.

Quickly the attack hit Ravel, and all she could do was scream as she struggled to extinguish the flames that burned her skin.

Luckily her suffering did not last long, for Grayfia, with a wave of her hand, froze the flames, thus preventing further damage to the poor girl.

Ravel's body had what were considered second-degree burns, but soon these burns began to fade due to the enormous regeneration rate she had.

''Whoever plays with fire can get burned...'' Altair thought about how cringe-worthy it would be if he said something like that right now.

''Are you okay?'' Grayfia asked, rousing Altair from his thoughts, so that he looked at Ravel who was on the ground.

''Y- Yes.'' Ravel mumbled, still in some pain throughout her body.

Even if she was no longer injured, this freezing Grayfia did not remove the 'phantom pains' she was feeling.

Grayfia nodded as she realized that Ravel was no longer life-threatening, and soon after that, she turned her attention back to Altair who sat back down while watching the people in the room.

''Altair, stop it, they've already learned their lesson.'' Grayfia said with a stern look on her face. She had noticed Altair's sudden mana increase, which meant that he could attack again.

''Yes... Yes...'' Altair waved his hand in agreement, not caring much for Grayfia's words. He then stood up from the couch he was sitting on, causing the guard of all the people in the room to rise against him.

This time everyone was prepared for any attack he saw from Altair.

Looking at the fearful looks the people in the room were giving him, Altair had a smile on his face.

''Relax, I'm leaving, you don't need to be scared.'' He said with a smile on his face. It was great fun for him to tease these people.

''Well, I'll be going now, I have things to do, and the sweets were great Neko-chan.'' Altair said while smiling openly at Koneko who was a little stiff upon hearing his words, but she nodded for fear that it would irritate Altair.

For Koneko it was nice to find someone with the same tastes as her, and even though she wouldn't admit it, she liked the nickname he gave her.

''Kai Kai.'' Having said that, Altair just instantly vanished from that place, leaving everyone perplexed.

''What was that?'' Akeno asked in surprise, because she couldn't feel Altair's presence around anymore. She was shocked that he didn't even use a magic circle to leave.

''I don't know, I've never heard of this kind of magic.'' Rias spoke in astonishment.

Altair kept surprising them.

This boy...'' Grayfia thought seriously. She would have to report this to her husband as soon as she returned home.

Grayfia knew that magics like the one he had just used were something extremely rare, and even though she didn't know what the maximum capacity of this magic Altair had used to get out of here was, she could tell by the ripples he had left here that it was a high level magic something rarely seen.

''I just hope the relationship between him and the devils hasn't reached a level of hatred...'' Grayfia thought as she looked coldly at Riser who was standing next to his servants.

She knew that many devils despised humans, but she also knew there were humans who could easily sweep away a huge amount of devils, she even remembered fighting some extremely powerful humans in the past.
