I don't own anything except for OCs. Please enjoy.

Kuoh Academy, one of the most prestigious academies in Japan, what was which an all female school is now a co-ed one. This is where Rias Gremory of the Gremory Clan and Sona Sitri, known as Souna Shitori of the Sitri Clan, 2 of the 33 clans that are currently active in the 72 Pillars of Devils. This is also where there respective peerages take classes. Currently we see Kiba Yuuto, a "Prince" of Kuoh Academy, Rias' Knight, Issei Hyoudou, One of the Perverted Trio, her Pawn, and Asia Argento, former nun turned devil, her bishop walking towards the old school building, their clubroom.

"A problem with Buchou? Maybe it has to do with the Gremory Clan." Kiba told Issei as they were walking towards the old school building.

Issei, along with Asia, had joined Kiba on their way to the clubroom. So he asked Kiba about Rias' behavior, but Kiba doesn't have any idea about it.

"Akeno-san might know about it though." Kiba added. "She is Buchou's best friend, so I would ask her."

Issei knew that asking Rias-Buchou about her problem was somewhat rude, but being concerned would be a good excuse, right? He would tell Kiba and Asia about what happened last night but it might cause a rampage if it got out. And he already gets kicked in the ass by the kendo team. With his mates though.

As they neared the clubroom, Kiba sensed a presence that would not normally be there and put on a serious face.

"It took me this close to the clubroom and I just sensed her now? I'm ashamed…"

Issei raised an eyebrow but shrugged 'Probably nothing, I guess' and opened the door.

"Hello" Issei said lazily as he, Kiba and Asia entered the room only to freeze in place. Except Kiba because he already knew there was someone there.

Inside the room were four people, three students of Kuoh, one sitting in an armchair behind the main desk, which was Rias Gremory, One of the 'Great Onee-Samas' of Kuoh Acadmey, one standing on the left of said desk, Akeno Himejima, Rias' Queen and the other half of the 'Great Onee-Samas' and one sitting in the couch, Koneko Toujou, the school's mascot. The last person was a woman dressed like a maid, Grayfia Lucifuge, Sirzech Lucifer's Queen and The Strongest. She was standing in front on the desk with her back facing the door.

Currently Rias had an unpleasant face while Akeno was smiling as usual, although there was a very cold vibe near her.

Koneko was sitting on the couch quietly with her usual poker face. It looked to Issei that she does not to get involved in what was going on. But maybe that's just of her poker face.

The room had a very tense atmosphere, you could cut the air with a knife and the knife would break. Probably.

Rias noticed the three enter the room and sighed.

"Looks like everyone is here" she sighed again and continued. " Before we start, there's something I need to tell you all."

"Ojou-sama, would you like me to explain what the situation is?" Grayfia asked Rias while the latter rejected her offer with a wave of her hand and shaking her head.

"The truth is-" Rias was cut off by a magic-circle appearing on the floor.

'A magic-circle? But everyone's here. Maybe someone like Grayfia coming?' Issei thought as the Occult Reasearch club and Grayfia looked at the magic-circle. But it looks like his guess was very off, but this would probably help him with knowledge of devils.

"The Phenex clan…" Kiba muttered, but Issei heard him as he was standing next to him.

Light shined all over the room, then flames came out of the magic circle, and the room was engulfed with heat. The shadow of a man appeared inside the flames. He flicked his arm to side and the flames dissipated.

"Been a while since I've been in the human world." The person said. He was a tall and handsome man who had blond hair and dark blue eyes and was wearing a red blazer with a black dress shirt with matching pants and black dress shoes. This man was Raiser Phenex of the Phenex clan.

"My sweet Rias, I came to see you." He said with a strong arrogance in his tone.

'My sweet Rias? What, is he like her husband or something?' Issei then knew, he was right on the something later on.

"Now Rias, let's go and take a look at the ceremony hall. The date has already been decied so let's go and see, yeah?" Raiser said as he grabbed Rias' arm.

"Let me go, Raiser." Rias said with a very serious voice as she tried to take his hand off her. By the look on her face she was very ticked off.

Raiser didn't seem to give a damn about his hand shook off and simply smirked. His arrogance seemed to be ticking Issei off as he stepped forward and faced him.

"Hey, you should stop being rude to buchou, you does that with a girl anyway?" he said with a clear voice which had a confidence. Riser looked at him like he got thrown into the dumpster and then sent to a dump truck.

"Oh? Who are you?" he asked with disgust apparent in his voice which was very different ot the cockiness of his voice earlier.

"Hyoudou Issei, Rias Gremory's Pawn." He answered with a hint of pride in his voice.

"…oh, okay." Raiser said without really caring.

Issei face-faulted after seeing his reaction. His pride got hurt by that. It's like he wasn't really cared about.

"Who are you anyway?" He asked frustaion showing on his face by the way Raiser brushed him off as to which Raiser was somewhat surprised by this.

"Oh? Rias, why haven't you told them about me? I mean, even if they're reincarnated devils they should know."

"I didn't tell them because I don't have to." Rias replied harshly.

"Ouch, you harsh as always my dear." Raiser said and starts chuckling. Then Grayfia stepped in.

"Hyoudou Issei-sama" She said with her usual stoic face.

"H-Hai?" He stuttered.

"This man is Raiser Phenex-sama. He is a pure blood High-Class Devil, and the third son of the Phenex clan." She explained.

Issei glanced at Raiser. 'So he must have a peerage then.' He thought. 'But what's he to Rais-buchou?'

"And future husband of the next heiress of the House of Gremory." Raiser finished for Grayfia with a cocky smirk getting wider waiting for their reactions.

'W-Wait, husband…? And the next heiress of the Gremory's… He's not talking about Buchou, is he?' Issei though as his face starts going pale.

"Yes, I'm engaged to Rias Gremory, you Pawn." Raiser said as if he read Issei's mind.

...

Wait what?

"Ehhhh?!" Issei screamed because of what Raiser said. The jackass was Buchou's fiancée? The left him very surprised and his jaw dropping.

At the same moment Grayfia cleared her throat to get everyone's attention and attention she got.

"Actually Raiser-sama you engagement with Rias-ojou-sama may become null and void do to some circumstances, so this is why this meeting was called." She stated and everyone froze in the room; disbelief on Raiser's face while Rias' had hope.

"What are you talking about, Grayfia?" Rias asked hopeing whatever circumstance it was, it would help her get out of her engagement with the blonde Phenex.

"A few days ago another older marriage contract came into effect." She answered shocking everyone in the room, Raiser looked at Grayfia like she just said a joke. Rias was bewildered because she didn't know if this was a good thing or not. I mean she might get out of her engagement with Raiser but what if the other man what somewhat like him?

"What are the circumstances?" she asked calmly with the hope of escaping both contacts.

"You can't be serious Rias, Grayfia please tell me this is a joke." Raiser said with anger in his tone.

"I already told you Raiser, I will not marry you no matter how much you act as a spoiled brat, now please answer Grayfia." Rias harshly stated which made Raiser seethe with anger, he opened his mouth to retort but Grayfia had released a small amount of her aura which caused the room to be slightly colder and made Raiser shut up.

"A few days ago the heir of a thought to be extinct House appeared in the Underworld, the father of said heir managed to create a marriage contract with the Gremory House years before the contract with the Phenex House, and his appearance made the contract into effect." She said and everyone in the room focused their attention on the silver haired maid.

"What's his name, what house is he from and why was I not told of this contract sooner?" Rias asked somewhat upset that this was kept secret.

"His name is Matthew Zagan of the House of Zagan. As for the reason you were not informed, it was because we only saw the contrac a few days ago as I said earlier." Grayfia explained and Rias nodded, accepting the answers she was given. But a Zagan, one of the extinct clans having a marriage contract with her family… Just how many contracts were there anyway?

"Ha, that guy probably died like the weakling he was." Raiser started with his cockiness back, "I mean come on, why would he show his face now? He must've been a little bitch ain't he?" He continued, which he should not have done by the massive amount of aura Grayfia was releasing which made him freeze in place while the room was filled with cold air, which made them shiver. Rias looked at Grayfia, her stoic and emotionless face had been replaced with a look of anger and disapproval.

Rias was shocked at what was happening; The maid never really shows any kind of emotion when she was on duty, but for her to release this much aura meant that Raiser insulted someone she must have respected.

"I would advise you to not disrespect someone like Matthew-sama, Raiser-sama" she said with a cold voice that sent shivers down their spines, her silver eyes looking straight into Raiser's blue ones as he felt like she was staring at his soul.

"Especially because you owe your very existence to him." She finished surprising everyone in the room.

"What do you mean Grayfia?"

"During the Civil War the House of Phenex had been attacked by one of the Old-Maou Faction's strongest squad, if not for the Zagan Clan the Phenex Clan might have been extinct." Grayfia answered still looking at Raiser who said nothing and just gulped.

"I apologize." Raiser said, but he didn't look like he meant it. Wanting to continue the topic Rias looked at Grayfia.

"So the Zagans had made a marriage contract with my family?" she asked the maid and the latter nodded.

"Yes, the head of the Zagan had made a marriage contract before their clan had become extinct, it said that for his first born child with the House of Gremory during the Civil War, the first agreement which made the contract go into effect was the Zagan heir and a child of Gremory must have a age difference of at most ten years and since he is eighteen the first agreement has been met, thus activated the contract." The maid explained.

"That doesn't matter because my contract is still in effect so Rias will be my wife." Raiser demanded as he stood up from the couch. Rias looked at him with disgust, hating how he basically just made her an object.

"That is why we are gathered here, once Matthew-sama and his queen arrive I will explain the agreement of the contract and what will happen with your marriage contract." Grayfia answered and Raiser sat back down.

"When will he be here then?" Rias asked and just when Grayfia opened her mouth a knock was heard which made everyone look at the door. Rias raised an eyebrow at the door as she hadn't felt anyone enter the barrie which surrounded the building nor could she sense anyone at the door.

"Come in" Rias said and the door slightly opened and a head popped up which made the girls, save for Grayfia and Koneko to blush.

The man had black haired which was slicked to the right, he had blood red eyes that made them blush even more, and had glasses, which kind of suited him, in Rias' opinion.

"Uhh, is this the ah, Occult…Research…Cl-Ow!" The man was interrupted by getting smacked over the head and the door was now fully opened and showed him wearing a black leather jacket with a red shirt underneath, he was wearing black pants and black shoes. It also showed another man who was slightly taller than the man, he had black hair although his was more bedhead styled, electric blue eyes and had a deadpanned expression with his arm near the other man's head while the latter was rubbing his head.

"You do know that Grayfia's right there, right?" The taller man said still with the deadpan look.

"What, I'm just making sure this is the place, Conner, jeez." The other man replied which made the taller man, now known as Conner, just sighed.

"Whatever you say, Matthew, whatever you say…" Conner replied.

They both entered the room and when Matthew closed the door behind him, he looked at Rias. Then sighed and pulled out his wallet and gave Conner 5000 yen, said man had a smirk on his face.

"Told ya it'd be her." Conner smugly said as Matthew glared at him.

"Yeah, yeah, Conner, laugh it up…" Matthew replied, slightly pissed that he lost another bet. He then looked Rias again and said

"Hey there, my name's Matthew Zagan, but Grayfia already told you that. And this guy is Conner Chase, my Queen."

I'm not entirely sure if this is good, so any advice would be appreciated. Thanks!
