Rias was surprised to see someone crash the party, it might've been the part she found the most enjoyable until she saw the face under the helmet.
"Alex?" Suddenly he disappeared, reappearing right next to her. A second later there was a concussion of notice and wind, as Raiser who was right next to her got blown away. Alex took her into his armor cladded arms, and said loud enough for everyone present to hear,
"I told you I'm not a hero, I'm a fucking dragon." He then pressed his mouth against hers. Unlike the kiss Raiser forced onto her that nearly made her sick, she melted into Alex's embrace. Everyone was in shock of the situation, until Raiser reappeared.
"Hey! Whose woman do you think you're kissing? It was already generous of me not to initially kill you, but apparently you want to die." At his words dozens of the Pheonix household guards appeared and surrounded Alex, he couldn't help but notice that there weren't any Gremory house guards though. Alex wrapped one arm around Rias, and flapped his dragon wings to crash through the roof, going outside. The guards followed them, and soon they were surrounded in the air.
"Kill them!" At his words the surrounding Devils created their magic circles, and a barrage of attacks flew towards them on all sides. Alex wrapped the two of them in his dragon wings, and with the enhanced defense balance breaker granted, endured them all. Seeing they were still alive, Raiser came forward once again.
"Do you even realize what it is you're doing? Rias needs to be with a devil, for the future of the devil races and houses. It was even her own family that allowed the marriage in the first place!"
"Shut up." Alex said with deadly calmness. Raiser looked as if he had been slapped, but apparently Alex wasn't done.
"You think I'll acknowledge the opinions of those that treat their family as nothing more than a breeding stock to be sold? " every member of the Gremory household felt as if their faces were slapped as well. Sirzechs as well looked as if he was being forced to swallow something bitter. He had wanted to help his cute little sister, but even his position isn't all powerful. He had actually started to admire this young man who bravely did what he couldn't. Alex actually knew all of this and didn't blame Sirzechs, but he currently had a part to play.
"Even if it's not me, it has to be someone within the devil race, the Gremory family can't continue as half-breeds due to your own selfishness." Alex then smiled, if the problem was that he wasn't a devil, then it meant that he just had to reveal one of his cards. His dragon wings swiftly disappeared, only to be replaced by a pair of Devils wings much to the surprise of everyone present. Magic circles appeared over the entire area that they were fighting in, and suddenly with the exception of Alex, Rias, and Raiser, all the others fell to the ground.
"So the problem is that I'm not a devil, huh?" Alex said with a smile as Raiser became considerably paler. Rias looked at Alex with more confusion with each passing moment from within his arms.
"From one Devil to another, I Alex, challenge you Raiser Pheonix to a battle to the death!" Before Raiser could reply, Grayfia flew up and said,
"Though Maou Sirzechs Lucifer will allow a duel for the hand of his little sister, he does not want any unnecessary taking of lives." Alex only sneered at her words, and pulled up part of Rias's dress, revealing a cut along her ankle.
"Raiser Pheonix personally ordered an attack on the heiress of the Gremory family, Rias Gremory. His exact words were to kill her, and her blood was spilt as a result. The only remaining child to inherit the Gremory household, or the third son of the Pheonix family, who is more important?" Grayfia paled at the realization, and the other Devils immediate started swaying their opinion against Raiser, due to the fact that Alex's words were true, they all heard Raiser give the order to kill the two of them.
Grayfia had an angry expression on her face for a brief moment, before returning to her impartial face. She looked to Sirzechs, who nodded his head in approval. Raiser on the other hand realized that the situation was quickly going against him due to his own carelessness. Rias was released from Alex's arms, and he quickly moved to position across from Raiser.
"I guess you'll have to learn the hard way, the Pheonix are the kings of fire! These flames of ours are hot enough to burn the scales of a dragon. Experience them personally!" Raiser summoned his wings of flame, and a large scale fire attack rushed towards Alex, engulfing him in the process. Raiser started laughing as if he won, until he noticed his flames doing something unexpected.
"Is that all the self proclaimed "kings of fire" have?" Alex asked calmly from the middle of the fire storm. The flames Raiser used to attack him then started moving a in a weird way, as they began to take a form, and eventually became a serpent of fire flying in the sky. Before Raiser could react, the serpent shot forward, and wrapped around him.
Even though he was the supposed "king of fire" he was unable to escape the fire serpent. As it held him there, Alex's armor started to shout,
[BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST BOOST TRANSFER!]
He shot forward and was right in front of Raiser, and opened his mouth. What came out weren't the flames of a dragon, or Pheonix, but the flames of a God of dragons. Raisers screams of death weren't even heard over the roar that lit up the night sky, and raised the surrounding areas temperature by several degrees. By the time the flames died down, there wasn't even ash left as the third son of the Pheonix family died.
"ALEX!" Rias shot forward and reentered Alex's arms as the duel ended, even though it was only a moment after it started. She kissed him once again, and he said,
"I have something better in mind than kissing." And without even paying attention to the others watching them, Alex picked her up in a princess carry, and flew away with her.
