The Last Angel and the Demigod Emperor

The Last Angel and the Demigod Emperor is a Fanfiction crossover story between the Percy Jackson Series and Highschool DxD, taking place at the beginning of The Son of Neptune. The world of DxD was nothing more than a husk of its former self, with only three survivors of the Trihexa Event, Gabriel, Ddraig, and Albion. Gabriel, through her will power and angel powers, is able to recreate the world with the help of Ddraig and Albion, but it is not the same one that they had lived in. Ddraig and Albion returned to their sacred gear prisons to continue the Dragon Emperor legacy and left Gabriel alone.

Gabriel's world is gone, nothing is left of it. There is no Rias, Michael, or Issei, but there is someone that makes her heart flutter. Could this 'Percy Jackson' bring her out of her despair?

Chapter 1
Percy was getting very tired of the two snake haired women, they would not stay dead. He had crushed them with a police car a day ago, and here they were having cornered him on a hill. So it was death by monster women or by hill and traffic, neither was very good.

He looked around, looking for anything that might help but he saw nothing. He nearly goes over the hillside when the first girl found him, still carrying the food sample tray. He moved away from the edge as he tried to move around her and was blocked by the other.

"Can we just call it a truce, I can't kill you and you can't hurt me." He said, hoping to misguide the two so he could get away.

"No, you have our sister's blood on you and she hasn't reformed yet!" The uglier of the two spat, Percy shook his head in confusion.

"I keep telling you that I don't remember killing her." Percy groaned, how many times had he told them that?

Before the woman could reply, Percy jumped forward and grabbed the food tray. Then put it under his butt, prayed to the god or goddess of stupid ideas and stunts and let rip. The speed set him down the hill and nearly into traffic filled lanes, but he survived and looked behind himself. The two were in the air and yelling bloody murder, so he got up and ran as fast as he could.

Percy then saw two girls ahead, one was old and the other was beautiful. He felt his soul being pulled towards the gorgeous female and he went right up to her and asked "Hey, do you need help?"

She looked started before answering "Yes, why?"

"Well, I have two snake haired girls on my tail at the moment so could I carry you out of danger?"

She nodded and allowed him to pick her up and get her into a piggyback position before taking off again. They never noticed the old woman glare at them and vanish into nothing. Percy was running as fast as he could and saw a gate with two armored figures guarding it. He was upon them in moments.

"Gorgons, run, now!" Was all he got out before he was pushed into a tunnel with one of the people, the other giving cover fire.

"I never got your names." Percy said.

"Hazel" the armored soldier said.

"Gabriel" the girl on his back said.

They exited the tunnel, the other soldier had joined them, there was a huge wall and swiftly moving river. Something about that river was unwelcoming, but hearing the sounds of roaring gorgons sent them into a dead run.

(Don't let the river touch you or you will lose the blessing of the river Styx)

Percy agreed with the voice but the river was getting closer and was too large to jump.

(Imagine a pair of white and blue wings on your back and I will instruct you from there)

Doing as the voice said, Percy felt his back get heavier and heard Gabriel yelp in surprise.

(Now, imagine that you are flying in the air like a dragon and will yourself to do it)

Percy followed the instructions and was flying in the air; he grabbed Hazel and the other person and was over the river in seconds. Gabriel got off him but Percy turned and faced the oncoming Gorgons. Thrusting his hands out, he bent the river to his will on instinct and the river grabbed the snake haired gorgons and tore them into itty bitty pieces. After that was over, Percy went over to Gabriel and helped her up before he noticed the crowd.

He was clearly not in the right time period; the armor resembled ancient Roman legionaries. His mind was telling him that this was the wrong place and he should run, but he wasn't going to leave Gabriel here with them. Percy wasn't in the mood to handle this, so he did something else instead. He turned to Gabriel to speak to her and was met with a hug from the beautiful woman.

When the hug ended, Gabriel smiled at him before a voice caught their attention.

"So, you are the one that I have been hearing about…Son of Neptune."

The speaker was a teen, wearing a royal purple shirt that was covered by armor and had a helmet under one arm. Her jeans had small holes in them but what stood out was the fact that she had two metal dogs on either side. But the metal mutts were shivering in fear, looking from him then to his wings. The other soldiers (or was it kids? They didn't like adults) looked nervous as well and it was at this moment that his wings spoke.

(I fear you may have overdone it with the river, though it may have been better if you had not. But, you have many abilities that may or may not turn these…potential allies against you.)

Percy blinked before glaring at his glowing appendages, not liking what the voice had said. But he didn't get a retort out as the girl from before, the leader of this place as seen by her metals on her chest.

"Hazel, bring them to my office, I want to talk to them before we send them to Octavian." She said before turning on her heel and headed inside.

Hazel looked at Percy and Gabriel before following after the girl, Percy followed her with Gabriel's hand in his own. The group moved quickly; though the voice barked at a ghost kid who called him a "Graecus", threating him to utterly obliterate the kid into nothing if he used that word again. The voice was clearly trying to protect him but it seemed to hurt more than help.

Hazel was talking to Gabriel; all of it was in Latin and was going faster than Percy's brain could translate. When they finally reached the girl's office, why she still hadn't given her name he didn't know, the girl turned to face them.

"My name is Rayna, praetor of the twelve legion" She began before pausing "You have some nerve coming here, after you blew up my original home."

It was the voice that spoke for Percy and it was not happy in anyway.

(YOU ARE SPEAKING TO THE NEW WHITE DRAGON EMPEROR, REYNA AVILA RAMÍREZ-ARELLANO! SPEAK LIKE THAT AGAIN AND I WILL BREAK FREE OF MY PRISON AND SHOW YOU WHY I WAS FEARED WHEN I WAS IN PHYSICAL FORM!)

This made Percy sweat drop, this could not be any good, not good at all.
