YN: Ten years ago I had a great life with my family then I was kidnapped by devil terrorist group then I was Rescue by man name Laurence Barnes they call me Prophet and I'm the only one who knows what coming Riser is not the real threat the most powerful fallen angels kokabiel still lives he show me a glimpse of the future he knows what drives me what I believe that being a good soldier comes down to one thing to one single question what are you prepared to sacrifice

Laurence: remember me

YN: when Laurence gave me the nanosuit i sacrificed YN gremory the man I was to become Prophet when my own flesh and blood held me back I sacrificed that too Replaced it like a spare part Victory costs Every time you pay a little more i saw a glimpse of what's coming and there was nothing left of me to stop when the greatest combat machine fails what do we then what do I do

It was a normal day at the Gremory residence, currently the younger members of the family were all in the living room, the eldest, Sirzechs was sitting on a couch watching over his siblings, avoiding doing the paperwork's he had to do, Rias, the youngest, who was 8 years old, was sitting on the floor playing with her dolls, and YN Rias' older twin brother, was just sitting on a couch reading. They were all quiet enjoying the silence. That is until a silver haired maid showed up.

Grayfia: Sirzechs-Sama, you still have work to do." She calmly said while standing behind Sirzechs spooking him.

Sirzechs: Will you stop appearing behind me?! Seriously, do I have to put a bell around your neck?"

Grayfia: This wouldn't happen if you didn't skip your work.

YN: She's right Nii-Sama said without taking his eyes off his book.

Sirzechs: You never take my side YN-Kun

YN: Because you never do anything right. said before Sirzechs got up and walked out of the room followed by Grayfia, to go to his office, leaving Kurosaki and Rias alone in the room.

They were in silence once again for a few hours, until an explosion could be heard on the other side of the house, surprising the two kids.

Rias: YN-KUN Rias yelled, scared by the noise, while running to YN. What happened?"

YN: "I don't know." He said as he made his way to the window with Rias. He couldn't believe what he saw. The garden was a mess, filled with craters, plants and grass on fire and the guards fighting what looked like invaders. The moment he saw an invader kill a guard he immediately put his hand in front of Rias' eyes and took her away from the window, he ran in the halls trying to find somebody that could help, they ran down a hall and when they were a about to make a turn YN stopped

Rias: What's wrong YN-Nii?" Rias asked with tears in her eyes, scared by what was happening.

He didn't answer. He only put a finger in front of his mouth signaling her to stay quiet. He went closer to the curve and took a look at the hall, he saw two hooded unknown Devils waking in their direction, while checking every door they.

"Where the hell are those kids?!" one of them yelled irritated by the fact that he couldn't find them.

"Don't worry. We'll find the Gremory heirs." The other one said.

When YN heard that he immediately knew that they were after him and Rias. He grabbed Rias and put her on a nearby closet that the maids used to store the cleaning materials.

YN: Rias I need you to stay here and be quiet, ok

Rias: "W-What about you YN-Nii?" She asked while crying.

YN: "I'll distract them and get them as far away from here as I can."

Rias: "Please YN-Nii, don't go."

YN: Don't worry I'll be fine, so please stay quiet." He said receiving a nod from Rias and closing the door.

After closing the door YN went to the hall where the two Devils were.

There he is!" One of them yelled.

Grab him!" The other one said before YN started to run in the opposite direction of where Rias was, being followed by the other Devils. He ran as fast as he could, he ended up in a room with no exit except for the giant hole in one of the walls that led outside. 'Dad's not going to like this.' He thought when he saw the hole, since he didn't have any other choice he went outside and ran towards the forest that was near their house, hoping that he could lose them there. He was starting to slow down because he was starting to get tired and they were getting closer to him.

"You won't get away!" One of them yelled summoning a sword and cutting YN across his back.

"YOU IDIOT!" The other one yelled. "We need him alive!" He yelled pointing at YN who was unconscious, lying face down with a cut that started in his left shoulder and ended on his right hip. His previously clean clothes were now covered in dirt and his blood.

"Don't worry. This won't kill him. It will make it harder for him to run away from us." The one with the sword said while smirking.

"Whatever you say. Now let's go, the Boss is waiting for us." He said as he put YN over his shoulder.

Unknown to them a strange figure in some kind of weird armor was watching them and now was following them

Meanwhile with Rias

She was huddled up in a corner of the closet, waiting for YN or anybody else to appear and help her. She then heard footsteps coming closer to her, she was starting to think that YN finally came back. When the door opened her hopes went down the drain, because instead of YN she saw one of the invaders.

"Found you." He said with a smirk as he grabbed Rias by the arm and pulled her out of the closet. "Stop struggling!" He said annoyed by Rias trying to free herself.

Rias: LET ME GO!"

"LET HER GO YOU BASTARD!" Rias heard, when she looked at the source of the noise, she saw Sirzechs running towards them and punching the man right in the face sending him flying.

Rias: ONII-SAMA!

Sirzechs: Rias. Where is YN

Rias: "I don't know."

Sirzechs: Can you tell me what happened

Rias: "We heard a noise and when we looked out of the window we saw strange men attacking the house, we ran looking for somebody to help and YN-Nii saw some of the people in the house, he put me in there and led the people away."

Sirzechs: "Grayfia, take Rias somewhere safe! I'll look for YN!" Sirzechs ordered his Queen, she did exactly that and grabbed Rias and took her somewhere safe while Sirzechs went on the opposite direction from them, killing every invader he saw while looking for his brother.

A few hours later with YN

He didn't know where he was, the last thing he remembered was that he was running away from the invaders in the forest, then he felt an enormous pain on his back and everything went dark. When he woke up he saw that he was chained to a wall in some old dungeon, surrounded by hooded people.

"So you finally woke up." Said a voice from behind the hooded figures. They made way for someone to pass and when he looked he saw a man with long brown hair that covered his right eye, wearing what looked like a black armor under a cape.

YN: "Who are you

"I'm Shalba Beelzebud from the old-Maou faction." He said introducing himself.

YN: "What do you want from me?!"

Shalba: "We want to make your brother suffer with the fact that he couldn't protect his family, we want to weaken him with that and take the opportunity to kill him, and since he's the strongest of the four Maou the other three will fall easily after him."

"Beelzebud-Sama!" One of the men called him while running up to him.

Shalba: what

There is a strange armor figure attacking us the man said.

Shalba: who dare attack us i want you to find him and kill him

Men: yes sir

Shalba: you stay here and all you to keep on eye on him while I deal with this intruder

He leaves and leaves the rest to watch YN soon the door opened a man in armor come in he hits one of the men with his elbow and stabs the other with a knife and grabs the other men and snaps his neck

( 0:28 to 0:33)

The armor come up to YN and started to Unchained him and then talk with a robotic voice

YN: yes I'm ok who are you

The man name prophet finally got YN out of the chans and brings him out of the dungeon and he saw everyone was dead even Shalba he bring him to a small cabin prophet bring YN inside there was only one bed a small kitchen and small bathroom
