A/N: Hi, this is my first fanfiction and I am doing it on High school DXD. This is my first fanfiction so any constructive criticism is much appreciated.

Just so you know the first few chapters will move quite slowly as it covers Ryuu's (my OC) childhood and him obtaining his peerage which will be full before canon start time. For the Harem it is currently looking like this

Harem: Ravel (main), Serena, Skye, Akai, Mizudori, Haruka, Le Fay

I will take suggestions for for the Harem and for Ravels peerage which currently only has Le Fay and Arthur Pendragon to suggest a character just leave a comment

Chapter 1

Ryuu POV

My name is Ryuu Vassago I am the next heir to the house of Vassago of the 72 pillars. I am not very well known about among the devils due to me being a half breed and in order to keep his a secret from the higher ups my father decided to have me be home schooled until I understood the situation and could hide my other powers.

I am quite short for my age standing at just above 4 feet tall, although according to my tutor I am smarter than most children my age proved by how I used to beat him at chess quite often. I am currently walking with my Okaa-san to the school I will be attending from now on.

"Really Okaa-san do I have to go to school" I don't want to go to school, I would much rather be playing games or watching anime but Okaa-san won't listen to me.

"Yes Ryuu, how many times it is imperative for any high class devil to go to school in order to receive their education, now come on your 11 now you can't carry on acting like a child."

"But Okaa-san I am a child"

"Well… Um, yes but that's beside the point come on Ryuu… you want to make friends don't you"

"Oh fine, I will go but can I get ice cream later"

"Yes, Ryuu-kun we can get Ice cream later if you promise to make lots of friends."

"Yay, Ice cream"

"Now, Ryuu-kun go on into school, I will see you at 4 o'clock"

"Ok Okaa-san" I said running into school.

As I walked into the school grounds I heard many whispers by the other students already here, they were saying things such as "who is that" and "he's so cute, his hair looks like fire" This was probably due to his flaming orange hair that was naturally spiked up and blew in the wind like flames.

When I reached the classroom I saw that their where 4 people already in there so I entered the room. I could see that they were older than me but we were in the same class due to the different years being in the same class, they do this due to the low birth rate among devils so this school only had two classes with only 10 devils in each class.

One of the four devils had crimson red hair that reminded me of our Maou Sirzechs Lucifer and she was clearly very beautiful even for someone who is only roughly 13 years old. Next to her stood a girl with short black hair that reached just above her shoulders and glasses that gave her a very intellectual look. Opposite her stood a glasses wearing onee-chan with long blonde hair that reached half way down her back, she also possessed quite a cold look on her face. Finally, the last devil was a tall muscly boy with short black hair, he exuded a confidence that only devils who know they are powerful can have.

I walked up to the older devils and introduced myself, "Hello, my name is Ryuu Vassago, rank prince, it's nice to meet you"

The new devils turned around clearly surprised to see me, and then promptly introduced themselves.

"Hello, my name is Sairaorg Bael, next head of the house of Bael, rank Great King" So the tall muscly guy is from the Bael family he must be the heir that has no power of destruction like I heard about.

"Good morning, I'm Seekvaira Agares, Call me Seekvaira, It's nice to meet you" The blonde girl said this to me, so the Arch duke is also here

"My name is Sona Sitri, rank Prince like you, let's get along"

"Hi, my name's Rias Gremory, heir of the Gremory clan and younger sister of Lucifer, Lets be friends"

And that tells the story of how I made my first friends.
