SHINNNNNNNNNE...
I teleported to an unfamiliar place with the magic-circle Grayfia-san gave me. I thought that I couldn't transport because I lack in demonic-power, however it seems like it worked, possibly because this magic-circle may be special.
I look around the place I appeared in. It's a very spacious corridor. On the wall there are rows of candles that is lined up till the end of the building.
Oh, there is also a huge portrait of a man with crimson hair on the wall. Is it Buchou's relative?
Oh, I don't have the time to be wasting here. I walk towards the direction where I can hear noises.
Then there is a gigantic door that is opened. There are huge engravings on the door. ...Is it a model of some kind of mystical beast? Well, that isn't important right now.
When I looked inside from the door, there are lots of Devils who are dressed up and are having a good time. These kinds of things are similar to the high society parties of humans. Well, I had never been in one though. Somehow, I imagined it to be like this.
I look at the Devils slowly to try and find familiar faces.
However, it certainly is a spacious hall. Isn't it bigger than the school field? The ceiling is really high up. The enormously gigantic chandelier is also amazing. So this is the hall people from Buchou's household organised. Oh my, rich people sure are amazing. I want to get my peerage quickly and become someone important.
When I was thinking something like that, a crimson colour appears to my eye.
A woman who has her crimson hair tied up—. She is wearing a red dress. I knew it with a single glance. Of course. That's because, she is the person I admire——.
"Buchooooooooou!!"
By the time I realise it, I had called out to Buchou so loud that it echoes throughout the hall. It gathers the attention of the Devils around me, and Buchou also looks towards my way.
That moment, I didn't miss the glimpse of Buchou who opens her eyes wide and shed a single drop of tear.
I also realise that she moves her lips saying "Ise".
The bastard Raiser, who is next to Buchou, also notices me. That jerk is trying to show off by wearing a fancy tuxedo! I then declare it after taking a big breath.
"To all the High-class Devils here! And Buchou's brother, Maou-sama! My name is Hyoudou Issei from Kuou Academy! I have arrived to take back Buchou, Rias Gremory-sama!"
The hall becomes even noisier.
Without any care about them, I walk towards Buchou and Raiser.
"Hey, you! Do you know where this——"
A person who seems to be a guard comes to stop me. However, there are those who comes in to stop the guards as well.
"Ise-kun! Leave this to us!"
It's Kiba. It's Kiba who is wearing a white tuxedo.
"...You are late."
A small build girl who is wearing a dress comes in to stop the guards as well.
"Ara ara, so you finally showed up."
Akeno-san who is wearing an expensive looking kimono is also present. All of them are stopping those who are trying to get in my way.
"Thank you."
I thanked them quietly and went towards Raiser confidently. When I faced him upfront, I say it straight at him.
"Buchou—Rias Gremory-sama's virginity belongs to me!!"
"...!!"
Raiser makes a face that you can't explain with words.
"What's the meaning of this, Raiser?"
"Hey, Lady Rias. What's the meaning of this?"
Relatives and authorised people are making unsettled faces and they are panicking. So the Devils, just like humans, gets confused when they face unexpected things huh.
"It's an event that I organised."
That moment, a man with crimson-hair who was sitting at the far back walks towards us. It's the person who was drawn in the portrait at the corridor. He seems to resemble Buchou...
"Oni-sama."
Buchou called this man that. Wait, Oni-samaaaaaaaa!?
T-Then this person is... M,M,M,M,Maou Sirzechs Lucifer-sama!?
"I wanted to see the power of the Dragon, so I asked Grayfia."
"S-Sirzechs-sama!? You can't do something irresponsible like this!"
I don't know who's relative he is, but a middle-aged man is panicking.
"It should be fine. The [Rating Game] from last time was very entertaining. But it was a bit disadvantage for my little sister who had no game experience to face off against Raiser-kun who is a prodigy from the House of Phoenix."
"...So Sirzechs-sama, you are saying that the last game wasn't fair?"
"No, no, not at all. If a Maou such as myself says such thing, then I would be making the old nobles look bad. The connection between the High-class Devils is important after all."
Maou-sama says it with a smile. From the way he spoke, is he aiding Buchou?
"Then, Sirzechs. What do you want to do about it?"
A middle-aged man with crimson hair asks Maou-sama. Crimson hair...is it Buchou's father!?
"Father. I want to make my cute little sister's engagement party into a flashy one. Dragon versus Phoenix. Don't you think it's the ultimate event? To stir up the party by having a battle between legendary creatures. There aren't any entertainment which can surpass this."
Everyone in the hall becomes silent with Maou-sama's words. Sirzechs-sama then looks at me.
"Dragon user-kun. You have our permission. Raiser, can you show your power once more right in front of Rias and I?"
Hearing Maou-sama's wish, Raiser makes a fearless smile.
"Very well. There is no way I can decline if Sirzechs-sama asks me. This Raiser will show his last performance before getting married!"
...Looks like he is eager to do this. With this, the stage for the battle between us is set.
Only thing left is for me to win! I'm raising my spirit, and Maou-sama asks me.
"Dragon user-kun, what prize do you want when you win the match?"
"Sirzechs-sama!?"
"What are you saying!?"
The relatives starts criticising at Sirzechs-sama's offer. However—.
"He's a Devil, so we need to give him something fitting for it since we are asking him to do something for us. Now then. I can give you anything. A peerage? Or the most beautiful woman?"
Maou-sama asks me while ignoring the voices of others around him.
—!
That is the best offer I can ask for. My dream lies in there. A peerage. And the most beautiful woman. With one word I can have either of it. However, I have already decided on what I will wish for.
"I ask you to give me Rias Gremory-sama back."
Maou-sama makes a very happy face when I answer him without any pause.
"Very well. If you win, you may take Rias with you."
With this conversation, it's decided that the battle between Raiser and I will commence in this hall.
"Thank you very much."
I bow my head to Maou-sama who went back to the end of the hall.
