Author's Note: hello all you readers out there. It is I, Shadowrallen. Damn, it's been too long since I've posted a fanfic on this site, but better late than never. As for some of my other stories, I'll get around to them eventually, but right now, welcome to my newest work, Fate/ Blue Blaze. This crossover will be set in the Unlimited Blade Works route, but that's enough from me, LET'S GET THE WHEEL OF FATE TURNING! P.S. "The boundary" is the Blazblue Universe, and the "Nasuverse" is the Fate/ Stay Night universe. Also, Yuyoko Kokonoe is basically the nasuverse counterpart to Professor Kokonoe.

"thoughts or telepathy"

'past words'

"speaking"

"Takamagahara speaking"

-Rebel 0: Prologue-

+Location: The Void+

A dark humanoid figure sat in an ebony chair, with three shadows cast behind him. Around him, white, empty nothingness stretched onward to infinity.

"Now, the Holy Grail War has been changed." The shadowy being known as Takamagahara, intoned. "The Boundary and The Nasuverse have intersected, and a Continuum Shift has been triggered. There shall be 14 servants, seven from this world, and seven from The Boundary. I wish to see just how great a change this causes. This shall be a most interesting world to observe."The shadowy figure sat back, and began to witness the countless possibilities.

+Location: Fuyuki University Dorm+

The room was sparsely decorated, and what little furnishings it did have were dull and unassuming. Renya Ochiai, a young man with silver eyes, shoulder-length black hair, a white shirt, and khaki pants looked at the strange purple emblem that had appeared on the back of his hand.

"Hmmm… So Takamagahara has intervened? Well, this should be fun…" He said, "I doubt many other people know what Takamagahara even is, let alone what it is capable of. But still, I'd best get my servant summoned as fast as possible…"

+Location: A small apartment+

Reika Ikagi, a 22-year-old woman with black hair and blood-red eyes chuckled as she examined the spiderlike crest that had burned itself into her palm.

"So, you've chosen me to fight in this war, eh Takamagahara? Well then, I won't let you down. I WILL win the Holy Grail and make my wish reality!"

+Location: unknown+

Yuyoko Kokonoe examined her hand. The grimalkin's pointed cat ears and forked tail twitched nervously. "I don't want to do this, but I guess I don't have much of a choice in the matter. Damn it all. Why the hell do I have to participate in some stupid war?" The girl stood up and went to gather her materials for a summoning, adjusting her glasses and grabbing a fresh lollipop as she left the room.

+Location: Fuyuki City residential area+

Sora Kohaku, an orange-haired college student clad in a blacks shirt, red hoodie, and gray pants, stalked down the hall and into his room. "Why?" he wondered as he flopped down on his bed, "Why is this happening now of all times? Just what is Takamagahara after?" He smashed his fist into the mattress, displaying the blue crest on his forearm.

+Location: A small shrine+

The purple-haired girl in priestess robes smiled evilly. "My ideal world is now within my grasp…" she whispered. "A world of Death…"

-End of Rebel 0-

Author's note: Sooooo… How'd you like it? I know it's formulaic, but I had to introduce some of the main OC's somehow. There are several divergences from both the Blazblue and Fate universes, done solely for narrative purpose or simply convenience. I hope to upload chapter 1 very soon. PLEASE STAY WITH ME! I would really appreciate it. Next chapter will be better and longer, I swear. Please read and review.
