''What are you doing here?'' Riser inquired trying as hard as he could not to advance against that human.
''I just wanted to know why I didn't get an invitation...''
With this line said by Altair, all the guests of the party started to laugh, since they never thought of inviting a human to a devil's party.
''Why would we invite a simple human to a party?'' One devil said in a sarcastic tone, this devil was trying to gain some points with the Phenex family.
Altair didn't answer the devil who had said that, since for him it would be a waste of time to answer someone so weak, he as he was here to cause a noise had other priorities, that's why he started to move a little closer to the stage where Rias was standing.
''Rias, so you forgot about last night? That makes me a little hurt...'' Altair said with some false tears dripping from his eyes, causing his two servants to have dark expressions as they knew what had happened last night.
''What happened last night?'' Rias asked confused, not remembering exactly what she had done.
''So you forgot... Well it was expected since I was very rough, you even lost consciousness...''
This last line from Altair made all the guests' faces change, especially Riser's and Issei's, both were pale upon hearing what Altair had just said.
''SHE WHAT?!'' Issei and Riser inquired together in total disbelief at what Altair had said.
They were imagining a scene of Altair and Rias in bed, but they couldn't imagine it, especially Issei who was in love with Rias.
''Didn't you know?'' Altair asked with a confused expression as he looked at Riser and Issei.
''What are you doing?'' Rias thought in panic, but chose not to deny Altair, not least because even she doesn't remember what had happened last night.
''I must say, she quite enjoyed last night...'' Altair said in an ambiguous tone causing the minds of all the people in the party to wander.
''He's the worst...'' Artoria and Jeanne thought at the same time looking at the act their master was putting on.
''Damn! YOU DAMN!'' Issei thought furiously as he imagined the scene of Rias sleeping with Altair.
''O- What my brother's fiancée, slept with this guy?'' Ravel inquired to herself in shock at this revelation.
''N- No!'' Rias denied this statement with a flushed face.
This scene was making all the guests confused, but they chose to continue watching, after all it was rare for things like this to happen in the underworld.
"You stuttered. Altair said with a playful smile as he looked at Rias who was blushing.
''Shut up!'' Rias said in a still blushing manner.
''You... how dare you...'' Riser muttered facing Altair with a murderous expression on his face, today was supposed to be a special day for him and his Phenex clan, but in the end all this had happened turning their big event into a real fiasco.
''Oh... You look annoyed, Riser-sama...'' Altair said sarcastically, causing pulsing veins to appear on Riser's forehead.
Altair found it very easy to tease Riser, he even regretted teasing him so quickly, as he still wanted to have some more fun while making some jokes, but seeing Riser's appearance, he knew he couldn't keep joking anymore.
''YOU BASTARD!'' Riser shouted furiously as he prepared to attack Altair who had a smile on his face.
''I think that's enough!''
An imposing voice sounded in the place causing everyone in the party hall to sound cold.
At the same time that this voice sounded, a scarlet magic circle appeared, and from this circle Sirzechs appeared next to his maid and wife Grayfia, surprising everyone but Altair's group, who seemed to already know about this intrusion.
''Who is that?'' Issei asked in a confused tone as to why all the people in the place were showing respect to this red-haired man.
''Onii-sama?!'' Rias exclaimed in surprise at her brother's appearance.
Issei who heard what Rias said finally realized who this red-haired man who had just arrived was.
''So this man is... Maou?'' He thought in shock, as he didn't expect to encounter a figure of such importance so soon.
''Sirzechs-sama, you don't need to worry about that, I will expel this worm immediately.'' Riser said in a respectful tone towards the man in front of him, because he knew that any word he said wrong he would be killed.
''Riser, out of curiosity I watched the Rating Game.''
Those words made and Sirzechs gaze upon himself made Riser stiff and afraid.
''Probably because you were facing my little sister, who had no experience at all, whose group was less than half of yours...'' As he said this, Sirzechs moved closer and closer to Riser, who was afraid with every step Sirzechs took towards him.
''Were you dissatisfied with the match?'' Riser inquired, as he instinctively took a few steps backwards. The pressure of the Maou is not something so easy to bear.
''No, No. Actually if I was dissatisfied, I could make the Rating Game disappear...'' Sirzechs denied Riser's question, while saying the last part with a smile on his face.
''But we have some special circumstances this time. Therefore, I would like to make a formal interruption.''
Sirzechs' words attracted the attention of everyone in the party hall.
''This is my dear sister's engagement party... And I would hate to ruin it.'' Sirzechs said pretending with a false tone of sadness.
Altair who saw this scene shook his head at Sirzechs' act of feigning sadness.
''Really a professional cynic...'' Altair thought, but he didn't complain either, after all he also knew how to be cynical.
''You, boy there.'' Sirzechs said addressing Issei who was still standing there in shock.
''And- Me?'' Issei inquired pointing to himself after coming out of his reveries.
''Yes, I would like to see him use the dragon's power, with my own eyes. Grayfia told me a little about this power.''
Issei who heard this became a little stiff, as he didn't expect Maou to ask him for something like showing his power.
''I see...'' Riser smiled as he understood what Maou meant.
''And of course, we can't forget our unexpected guest...'' Sirzechs continued saying, but now he was looking at Altair.
''I'm glad you didn't forget about me, Maou-sama...'' The tone of sarcasm in Altair's voice was evident, causing many devils to frown.
''You bastard!''
''How dare you speak to Maou-sama with such disrespect.''
''He doesn't even deserve to speak his name.''
Many devils began to speak loudly, seeking to defend the Maou, but Altair seemed not to care about that and continued to look at Sirzechs with a smile on his face.
''Enough!'' With just that word, they all immediately stopped their argument and started listening attentively to what the Maou was saying.
''As I was saying... What I propose is a fight between the three of you...'' Sirzechs didn't want to beat around the bush for too long, so he went straight to the point causing several people to widen their eyes in surprise.
''A fight between Dragon, Phoenix and a Human. Two heirs of legendary powers and one, whose limit cannot be calculated, those three in an epic battle, what do you think of that?''
Riser who heard Sirzechs' proposal had an overbearing smile on his face, as if victory was already within his grasp.
Altair just gave a smile at this proposal.
While Issei, widened his eyes in surprise at Sirzechs' statement.
''O- Onii-sama.'' Rias inquired in shock upon hearing that statement.
''That's why he's Maou, really a person with great ideas.'' Riser commented with a smile on his face, thinking that what Maou had done was so that he could increase his reputation even more.
''Hey, dragon boy.''
Issei snapped out of his daze once again as he heard Sirzechs voice calling him.
''S- Yes?'' Inquired Issei a little hesitantly.
''Would you show me and everyone here your power?'' Sirzechs asked extending his hand to show the people who will be watching him.
''...Right.'' Issei replied a little fearful, but still agreed with Sirzechs proposal.
''Issei, don't do that!'' Rias exclaimed being worried about her pawn.
However, Riser stood in front of her to prevent her from going towards Issei.
''I, Riser will show you one last time the power of the flames, before you two are pulverized!'' He declared with an arrogant face, while making some flames overlap his own body.
''Did he really say that?'' Jeanne muttered to Artoria.
''Yeah... he did.'' Artoria only confirmed Jeanne's murmur.
''He's really fucked up.'' Jeanne commented only to earn a quick nod from her friend.
''Oh, right... Dragon Boy, what would you like to win if you win?'' Sirzechs inquired causing the other devils to widen their eyes in disbelief, since for them just the fact that a low-level devil could talk to the Maou was already quite a reward.
Sirzechs-sama! Do you want to offer a prize to a low-class devil?'' One of the guests inquired, and soon after his questioning others followed him.
''Low class or not, he is also a devil.'' Sirzechs replied with a stern look at the devil who just bowed his head as he left the hall.
''And since he accepted my request, he should also get something in return.''
After those words from Sirzechs everyone focused their attention on Issei, since he could basically ask for anything.
''So, what do you want? Wealth? Eternal beauty? Come on, you can ask for anything you want...'' Sirzechs asked Issei quietly. Besides Sirzechs wanted to see what his little sister's pawn would choose.
''Buchou... No, I want Rias Gremory-sama... I want her back!'' Declared Issei loudly, making Rias blush deeply at his words.
And this response from Issei made a smile of relief appear on Sirzechs face.
''You've got balls boy...'' Artoria commented as she looked nonchalantly at Issei.
''O- Thank you...'' Issei thanked him a little blushing.
''Since that's the case, let's begin...''
As he said this, Sirzechs snapped his fingers causing a huge magic circle to appear on the scene, involving Issei, Riser and his peerage, Artoria and Jeanne, and lastly...
Altair.
