The Sacred Gear of Victory

Prologue: ? : "I am..."

- - - ? - - -

[I am invincible!]

"This dream again..." I grumbled and sighed with some frustration. For some reason I can never seem to remember having this dream when I'm awake.

[The strongest amongst the strong!]

It was always the same dream. A voice that echoed in the darkness. I was almost sure that it was male. And yet I could never seem to simply bring myself to call it "he".

[The one who possess victory in all its forms!]

It would sometimes tell me stories. Sometimes it just bragged about its achievements.

[The one feared by the evil, the tyrants and the sinful.]

At some point, I've memorized most of what it would say... so I had tried conversing with it, but it never said anything back and just kept saying it's old lines time after time. Perhaps I can only hear it, and it doesn't know that I can hear it.

[The servant of the immortal sun.]

Was he ignoring me? Or am I the only one that could hear? It seems to be introducing itself to me.

[The untouchable, the powerful, the graceful, the unyielding, the destroyer, the liege, the swift, the undefeatable, the righteous, the slayer!]

But every time that it seems like it is about to tell me its name...

[I am...]

I always wake up.

Author's Notes: First things first: No, I have not dropped Pet na Campione-sama. I do apologize for not releasing anything. (I feel especially bad, since I actually told someone that I might update before September ended... and it's already October. Sigh...)

Anyway... like most of my filler prologues, it is incredibly short. I've already written the next chapter, but I'd like to read what people think so far. So please review.

This crossover story was inspired from my search for characters and myths to use for my main fic "Pet na Campione-sama!" and my desire to see more creative crossover stories. I had felt that crossover-fan-writers are limiting themselves by forcing to two worlds to meet, and so I wanted to write an example of a crossover that takes elements from one series and blend it into the other's world. I had originally intended this as a one-shot, but I've instead decided to write it as a longer story with several chapters. This was because originally I intended to write this in the 3rd person, but I thought that writing in that style would make it harder to return to the style I use for "Pet na Campione-sama!", so I decided on a multi-chapter story so that I can use the style I've become more accustomed to.

This is a Godou x Rias + Harem, and while I do hate the fact that I'm crossing over my favorite character and (might be) outing someone else's in the process- my creative juices told me to do it- so I apologize to Issei's fans. Although, I do have a challenge!...

Challenge!: I would like to read a story where in Issei is added to Sona Sitri's Peerage instead of Rias'. This was a thought I had after reading High School DxD volume 14 Life 4 (I won't give spoilers for either my idea or what happened in that volume, but you can pm me about it if you're thinking about using some of my idea. Or if you're really curious).
