Prologue:

"Onii-sama, don't go!"

"Kunou! Let go!"

"No, I want you to stay!"

"Uh, Yasaka-sama? A little help, please?" I ask the gorgeous blonde-haired bombshell that I had the pleasure of working for. Frankly, I'd work for free if it meant I could work in the same vicinity of this goddess, not that I'd ever say no to some cash.

"Hmm? Kunou, you little baby, come here," Yasaka tells her only daughter. "Leave Rokkun alone." She then starts tugging the little girl, trying to pull her off my leg. Uh, Yasaka-sama, you do realize you, with your unequaled body, are extremely close to a very healthy teenager, right? And frankly, I can see somewhat down your yukata… Thank you very much, Yasaka-sama! You will never know my gratitude!

With a final heave, the little girl is pulled away and scolded by her caring mother. I smile at the two. "Ah, thank you, Yasaka-sama. Once again, you have saved me."

"Nonsense. I just have to apologize for my daughter's behavior." She looks pointedly at the little girl, who is on the verge of tearing up.

"I~ I'm sorry, Onii-sama… I just want Onii-sama to stay near me always."

"Hey, Kunou, don't worry about it. I'll be back every now and then to play." With my comforting smile, the little girl's face brightens up and she hugs me as tightly as possible. I returned the hug, then told her to head back inside, and see her wave goodbye.

"You know, it's not good to go hitting on little girls, even if she is your future bride."

"... Yasaka-sama, pardon my lack of manners, but I am not a lolicon, if that's what you're implying."

The blonde just laughs merrily at my comment. "Oh Rokkun, you crack me up. If only you were a few years older - I wouldn't mind playing with you either," she said with a slight smirk. "Maybe in a few years… but then, I would be competing with my own daughter!"

"Your daughter is seven right now. In a few years, she'll be, what, ten? How will that even be a competition?"

"Now, now, a mother must not steal her daughter's husband. It's an unspoken law."

I frown at the mention of this. "Yasaka-sama, may I ask you why you agreed to this? I mean, there is somewhat of an age difference between Kunou and I… isn't it too early to even consider marriage for your daughter?"

The young woman beside me sighs. "I quite agree, Rokkun. But you have to remember that I was married by fifteen and had Kunou within the year. With so much stress it takes on the body of the nine-tails, the successor has to be decided quick, in a manner of speaking. And we have to prepare quickly, so that all the requirements for the proper mate can be met. After all, quite a few of the best qualified get taken quickly." She then smiled tenderly at me. "We're just lucky the best was available."

"... I fail to see exactly why I am the best, to be perfectly honest. In terms of power, I'm relatively small, being only a six-tail. As for connections, since I stay in the shadows, most are unaware of who I am. For me to become what amounts to a king, based on that, it would be dumb."

"Ah, but please know that the nine-tails does not need a powerful mate," explains the blonde beauty, "but one who can protect her. Kunou will have more than enough power - she might have more potential than I do, and I'm considered the strongest nine-tailed fox in the past two centuries. But there is always the blind spot that might prove our downfall. That's why it's detrimental for the mate to cover it. My husband covers it by using his contacts to have the best of the best protect me. But you, Rokkun, you will be able to do it by yourself."

"... And my father happens to be a famous kitsune that will offer his ninjas to the service of Kyoto whenever is needed. That has nothing to do with this arranged marriage?"

"Like I said, my husband has contacts." She then looks into my eyes, ready to prove her point. "But I would trust no one else to protect my daughter."

I still don't really like it - it's just kind of annoying that my life is being forced on me. But, then again, if Kunou looks even remotely as hot as the miko-clad Queen of Kyoto next to me, then I will be a very lucky man. And since she looked like Yasaka-sama in miniature, it's pretty much assured. I might as well count my blessings now.

"Anyways, about your mission - you understand that one of the cat's has been rogue for a number of years, correct? You are assigned to protect her sister, who happens to be the servant of a devil. Make sure that neither the cat nor her current master harm her - though neither will most likely ever occur."

"Ah yes, the Gremory clan is quite famous for caring for their servants."

"Indeed. Now, the kitten does not know why her sister went rogue. I wish to keep it that way, for now. Seeing as reports suggest the rogue cat has joined a potential threat, it would be unwise to let the girl know of her sister's actions, both past and current.

"Also, it has come to my attention that the Gremory master has quite an unusual liking for Japan. Though I doubt it will ever come to this, if the girl ever has plans to conquer Kyoto, I wish to have her assassinated - knowing your skills, no one would ever know the strike came from us. However, this is a last resort, and there is a very good chance it will never happen."

I give a slight nod. It's a standard reconnaissance mission to determine potential hostiles and take them out, if necessary. In other words, child's play. I've been trained to do this since I was three. And since there's little chance at actually getting my hands dirty, it's almost a paid vacation. Still, having to go back to school to shadow teenagers the entire time will be quite the pain.

"Well, best be on my way. I'll probably miss the opening ceremony if I don't leave soon."

The blonde kitsune smiled. "Be careful, and do well on your grades. From what I hear, there are many beautiful girls at your new school, so enjoy the time there, but not too much - we wouldn't want any unexpected claims to the throne in the future, would we?"

"... Yasaka-sama, what the hell are you talking about?"

"A good looking guy like you should get plenty of girlfriends."

"I know you know it already, but I like older women."

"Like me?" A playful smirk pops up on her beautiful face, and I quickly nod confidently. I firmly believe there is no point in hiding your interests. "Now, now, don't play with the teachers too much. We wouldn't want the Kunou's future husband to become a full-blown womanizer, would we?"

"Yeah, whatever. I'll be back every now and then." And with a small wave of my hand, I disappear. Kuoh Academy. This was going to be quite a painful and boring three years.

Welcome! So, I was reading Highschool DxD, and all of the sudden, it came to me: "What the hell is Japan doing during this?" I mean, seriously, you have three Christian-originated factions all of the sudden descending on some random former all-girls school in the middle of Japan, and the Shinto faction does nothing until Kyoto is attacked? I seriously doubt Japan would be pleased a war was started on their home turf without their consent.

So, insert original character to keep an eye while the world starts descending into chaos. Now, Kurotani Rokudou, affectionately known as Rokkun (Japanese like to shorten names), is not an OP character, though he may seem like it at the beginning. That's strictly because he is experienced, whereas the Occult Research Club and the Kuoh Academy's Student Council have all of a few stray executions on their resumes. Don't worry - the lovable idiot known as Issei will still grow up to be the Greatest Pawn and everyone else will increase to the point where Evil Dragons have to start to worry (whoops, spoiler alert). Rokkun's role is solely from the shadows, and he's more or less support, taking out the minor bad guys that for some odd reason never are mentioned when all the big bads decide to attack a bunch of teenagers.

Rokkun's also somewhat of a pervert - he understands many of his fellow students at Kuoh are knock-outs and likes older women. He just isn't so obvious at it as the Perverted Trio. But unfortunately for Rokkun, high school romance at a school where most of the students are members of the fairer sex will not go as smoothly as he hopes (to be fair, he would rather have none). Yes, he'll have a harem. But it will be a harem he doesn't want.

Anyways, I hope you enjoy. Feel free to comment. I don't even care if you bash the entire thing for no reason other than "it sucks." I'm a big boy and can always ignore those. See ya.
