I do Not Own Either Highschool DxD or The Familiar of Zero.

Chapter 1: A New Magic on Earth

(Saito)

Hello everyone, I'm Hiraga Saito. A year ago I was summoned to a different world full of magic, where I became a familiar to Louise. I've been through a lot since then. The first thing was a fight with a mage, after that I had to fight a giant Golem, then I took on an army of 70,000 on my own, and of course fought a giant Dragon. Well, it was an interesting year. But now I'm back home I can go back to my normal everyday life, except Louise is also here, as my wife. Anyways, right now we're going to school. While I was gone dad got a new job, so now I have to go to a different school. I think it's called Kuoh Academy. Anyways, I'm going to be a third year, because I was able to somehow catch up, and Louise is going to be a first year.

"Hay Saito, why aren't we in the same year."

"Louise doesn't seem to like the idea of us being in different years.

"That's because in this world your 16 and I'm 18. A 16 year old is a first year and an 18 year old is a third year. Anyways, weren't you the one who wanted to go to an Earth High School?"

"Shut Up!"

The next thing I knew, I was kicked between the legs. She's not going to change anytime soon I see.

We were at school now. Louise is in her class and I'm in mine. Right now I'm in the middle of introducing myself to the class.

"Hello, I'm Hiraga Saito. Please take care of me."

The entire class seemed disappointed in the fact that I was a normal looking guy. Well, can't blame them. I looked around the class, and the first thing I noticed was a girl with long crimson hair. She was by far the most beautiful girl I've ever seen, even more beautiful than Tiffa. "Ok Mr. Hiraga, you can sit next by Miss. Himejima." I looked over at this Himejima person was almost as beautiful as the crimson haired person. I took my seat, and for some reason I felt a dangerous glare aimed at me. Must me the guys in the class, looking at me with jealousy. "Hello there, mind if I call you Saito-san?"

"No, I don't mind."

She was talking to me! If Louise saw this, she would kill me.

"Ok then Saito-san, if you need any help then just ask."

She's a nice person. I hope I met more people like her in the future. After that, class started. When class ended I quickly left before the guys attacked me. They don't seem to like the idea that Akeno-san. I ran to outside and heard some noise coming from the side of the building. I took a look and say three guys behind a dojo looking building.

"What're you doing?"

They quickly looked over at me.

"Don't talk so loud!"

"What was that noise?"

"It must be those three ideas again"

"We've be found!"

"Run for it!"

Two of them ran while leaving one of their own and me here.

"I knew it was you, and you brought a friend."

Behind me was a group of scary looking girls. I think they were doing.

I was tired. Me and this other guy ran like crazy from those scary girls. Who did this happen to me?

"Thanks for saving me there. Those bastards, Matsuda and Motohama. Just leavening me there like always. If you weren't there to save me then I would be dead by now. By the way I'm Hyoudou Issei, a second year student."

"Hi, I'm Hiraga Saito. I just transferred here as a third year student."

"Really, so you're my senpai. Well I wish I could stay here, but I got to go."

Issei left with that. Well, I better get going. Just as I was about to leave, I felt a sudden chill go down my spine. I turned around and saw Louise glaring at me. Why does she seem angry?

"Saito, mind explaining why you were being chased by a group of angry girls?"

She seen that! This isn't good!

"Wait! This is a misunderstanding!"

"Shut up! You stupid DOG!"

[Explosion!]

"GAAAAAAAAAHHHHHHHHHHHH!"

It's a good thing school was out.

(Rias)

Hello there, I'm Rias Gremory. Right now I was standing right where I felt a huge amount of magic. Is there a new devil here? Can't be, I haven't heard anything like this, and it didn't feel like Demonic Power. It wasn't like anything an Angel or Fallen Angel would use either. In fact I don't even recognize this kind of magic.

"Was it a human? Don't tell me they managed to create a new type of magic on their own."

If so, then this would be the first time in history since Merlin. I better report this to Oii-san. He'll want to know about this. I left the scene after repairing the damage. I make my way to the old school where my lovely servants were waiting for me.

"Buchou, what kept you?"

The one who asked me this was my Issei, or Ise as I call him. It was thanks to him that I was freed from my engagement. He's the one I fell in love with, but he doesn't seem to know my feelings. Asia also has feelings for him, so I can't leave them alone too much. Anyways, I better get back on track.

"You might have noticed, but a huge amount of magic was relesed here at school. I was checking out what it was. It appears to be some new type of magic. I can't let this go unchecked. I'll stay here and write up a report for my brother while the rest of you go and try to find the caster. I believe the person to be human."

(Issei)

Hello there, Issei here. Under the order of Buchou, we, the Occult Research Club, were looking for this mage. According to Buchou, it was a powerful magic that had the same destructive force as her Power of Destruction. That's kind of scary, and the caster is human. I didn't think humans could use that kind of magic. With me is Kiba and Asia. Koneko and Akeno are searching the southern end of town, while we searched the northern end of town. Asia had her familiar, the Sprite Dragon Rassei. Because he's a Dragon he has a stronger sense of magic then we do. Akeno's the one who searching for the magic in her group. Anyways, we were following Rassei. He seemed to pick up something. As we walked I saw someone walking on the other side of the street.

"Damn the Louise. She just doesn't seem to hold back when she's mad."

Isn't that Saito-senpai, what's he doing here? And isn't that a sword on his back? What's going on here?

"Um, Rassei seems to be pointing towards that guy over there."

What, Saito-senpai? He doesn't look like that wizard type, but since Rassei's the one we have to depend on, might as well go and check it out, besides I want to know why he had that sword. We walked towards Saito-senpai.

"Hay, Saito-senpai!"

Looks like I caught him by surprise.

"Oh, it you, um…Issei right."

He had a hard time remembering my name. Well, I can't really blame him for that. Just as I was about to ask him a question, when he looked behind me.

"Um, is that a tiny blue Dragon?"

Crap! Rassei's still out! What're we going to…wait a minute. He doesn't seem all that surprised.

"Um, senpai, aren't you surprised about seeing Dragon."

"Yes, I didn't think anything supernatural existed in this world, but it does. I'm guessing you're not what you seem either. Damn, if it wasn't for all the things I seen back in Halkeginia I would be surprised beyond belief. Wait, Louise came here thinking she could see a world without magic. If she finds out about this then I'll be a dead man!"

Whoever this Louise is she must be incredibly scary. But what's this Halkeginia that he's talking about.

"This at least proves that he might be the one we're looking for."

"Looking for? What're you talking about?"

Senpai seems not to know what we're doing here. Well, I think we should talk about this with Buchou.

"Saito-senpai, will you come with us. We'll explain everything to you later."

"So you're wondering about that magic earlier today at school? That was Louise getting anger. Every time she gets mad at me she either kicks me in the one place a guy should never get hit, whips me, or casts the [Explosion] spell on me."

We brought Saito-senpai back here to the club room. It seems that this Louise is the scariest person her alive. We told him about the magic in this world. In exchange he told us about that strange magic. It's a powerful magic from a different world he refers to as Halkeginia, which is just a continent, but that's the only part he knows. Anyways, this magic, I think he called it Void magic, is the strongest magic from Halkeginia that only four people can wield. According to him, right now there are only two, and this Louise is one of them. Void magic huh. Something tells me that I don't ever want to make this Louise angry at me.

"So than, it's a magic form a different world. Tell me, if you're from this world, then what's your relationship with this Louise?"

"She summonsed me as her familiar."

"…"

"…"

Did he just say familiar? A human can become a familiar?

"In Halkeginia the familiar you get is based on the element you use. For example, a Wind magic user can summon a Griffin, a Water magic user can summon a frog, a Fire magic user can summon a Fire Salamander, and an Earth magic user can summon a Mole. It just so happens that Void magic users summon Humans."

So that's it. It makes sense I guess. Buchou also seemed to understand what happened. This Louise must have gotten mad at Saito-senpai and used her [Explosion] spell on him. After Buchou was satisfied we told him about us. He was a little surprised to hear that we were Devils, but quickly accepted it. After we were finished I took Saito-senpai and walked him to the door. Just wait tell Akeno-san learns about this. Just as we were leaving, I heard someone shout.

"Saito! You said there wasn't any magic in this world! And you told them about Void!"

"What, Louise! I can explain!"

I look in the direction of the voice, which apparently belonged to Louise. The first thing I noticed was Akeno-san and Koneko-chan. Standing near them was a short girl. She had long pink-blonde hair. Her breasts were small, but I couldn't help but think that she was a very beautiful girl.

"No excuses, you stupid dog!"

Saito-senpai started to runaway.

[Explosion!]

"GAAAAAAAAAHHHHHHHHHHHH!"
