On the dawn of the fifth holy grail war, a certain serial killer finishes off a family leaving their 11-year-old son behind

for his malicious whims. To the misfortune of the Sonton family Ryuunosuke Uryuu was having a wonderful day, he got

to paint a lovely home crimson red and even found a fresh sacrifice for the spell book he stumbled upon. As far as he's concerned

the spell could fail, in which case the boy dies either way or it could work and he'd get to see a genuine DEMON!

"Let's get this party started" the madman cackled reading out the incantation as the circle of blood began to glow the boy within the circle

young Niel began to cry resistance as dead as his family. In a flash of scarlet light, a figure could be seen where nothing stood before. A blue haired teenage boy wearing a school uniform of unknown origin looked apathetically at his surroundings. Ryuunsuke was overjoyed and confused at the sight. "It actually worked!" He cheered ecstatic at the revelation that magic exists.

"Hey, are you a demon? Want to eat this kid?" He beamed. The unknown boy glanced at him before looking at the child and kneeling before him "Do you hate him?" he asked the sacrifice. Niels fear made him hesitant but the burning feeling within him quickly grew until at last "y-yes... YES!" he cried tears overflowing, the teens emotionless face twisted into a sinister grin as a dark light shined in his eyes "good, a growing minus needs something to nurture after all" instantly the room was warped into a thorny hell of screws puncturing everything especially the summonner himself.

Ryuunosuke had no time to react before his limbs were pierced "AAAUGH" he screamed one last time before a hand viciously tore into his chest and slowly dragged out his heart "I'll have better use of this seeing as you never used it" the teen taunted before swallowing it whole. The last thought the killer had before darkness took him was that he was out of his depths.

Niel could only stare astounded as the man who took everything from him was slain so casually. "Now that the inturruption is handled, lets get down to business" The demon? says with a exaggerated twirl to face him "I am caster Kumagawa Misogi" Those dark blue eyes bore into the orphan boy "How would you like to be my master" he grinned.

[1 hour later]

The house Niel had known for all his life was transformed utterly as screws of all kinds furnished the place. Kumagawa said it was to protect them but Niel doesn't understand what they needed to be protected from.

Didn't Kumagawa kill the bad man? What more could trouble them?

"Honestly, tons of things but assasin would be the biggest one. With my master being a child the last thing I need is him/her finding you" the caster sighed spinning on one of his screws like a chair. Niel didn't know what to think at this "Why would 'assassin' look for me? What did I do" he cried fearing more violence.

Kumagawa rested his head on his hands "Everything, and nothing my dear 'master'" he pointed at niels hand where a crimson tattoo had appeared upon accepting Kumagawa's offer "We are at war, 6 other master servant pairs. Each of them with a wish they're willing to KILL for" he chimes the smile never leaving his face despite the growing terror on Niels. "I DON'T WANT TO DIE" he screams "Then kill them first" Kumagawa replies nonplussed "The only way out is victory I'm afraid. As a master you are one of the objectives the others must conquer" Niel was beginning to lose hope once more "But worry not. While losing may be my specialty, I'm no slouch at killing either" a malicious expression dominated Kumagawa's face "If I can't handle the servants we could always off the masters instead"

Niel was speechless, he didn't want to kill but at the same time he had no desire to be killed either. As the tears threatened to come again Kumagawa lead him to his room "I believe you've been through a lot today, with your family getting murked and all" he said carefree "Just leave it all to me" The servant closed the door leaving Niel to his dreams.

-Niel dreamed of loss.

Defeats and near victories of an unknown boy in blue constantly striving to win only to relive defeat over and over again. Turning from a boy to a teenager growing more twisted as the days passed...

As his master slept Kumagawa thought over his situation, as a servant he found his minuses worked the same if not stronger in the case of his signature moves. Bookmaker seemed more potent where as all fiction was about the same. "old reliable till the end huh" he chuckled, wondering if Anshinin was still around he left the house with bookmaker screws guarding the home. "While my 'summoner' had a good heart the magic won't last me nearly enough" he decided that some lovely 'donors' would be greatly appreciated. Kumagawa began to look for 'undesirables' as the days went on Fuyuki city would gain a new urban legend of the 'azure man' a boy in blue who took the mighty leaving nothing behind...

[Half a week later]

A surge of mana radiated throughout the city as two servants clashed, Kumagawa who was currently eating takeout with his master paused as the war seemed to finally begin, a smile grew upon his face as he rose "[Seems like this caster has some business to attend to. You finish eating, I will return shortly]" as if he was never there to begin with Kumagawa's frail form vanished leaving Niel alone. 6 miles away Lancer and Saber clashed for the 4th time Saber looking worse for wear as Lancer frowned yet continued his pursuit "It saddens me that we must meet like this but my master command is absolute" He readied himself for the final blow as Saber began to focus "Saber!" Irisviel began to pour more mana into her "I won't fall so easily, lancer" Saber's blade began to reveal itself the shine growing stronger. She knew she had to finish this now before he cripples her any further.

Before they could continue both of them sensed a disturbance as they quickly leaped away seconds before a sea of screws ruptured from the earth "[shame]" a voice echoed as a boy stood on a nearby light pole "[A second later and I'd have two servants down]" he clucked his tongue despite the ever-present smile on his face. Both servants were on alert at this newcomer "Who are you! How dare you interrupt this battle" roared the enraged lancer. The boy's expression twisted as a sinister smile crept on his face "[Kumagawa Misogi at your service, though I believe 'caster' would be more relevant]" he laughed giant screws forming in his hands

Irisviel was shocked that he gave his name so easily but couldn't recall any figure by that name. "Saber, be careful this is an unknown were dealing with" The blond knight nodded holding her blade all the tighter.

Before anything else could occur a voice roars out as lightning strikes the earth between them "That's quite enough" A red-haired giant riding a flying chariot appears in the sky, "All of you, sheathe your blades! You are in the presence of a king." Boomed the man "I am rider Iskander the king of Conquerors!"

Kumagawa didn't know if he should stay or leave at this point...
