Fate/Zero:HOPE

Not What Was Expected

The summoning was a success.

That much was readily apparent when the light died down and there was the red-garbed Heroic Spirit, already kneeling in subservience. In the darkness of the cavern below the Matou residence, the red of the Servant was the only colour that was not somehow stained by the filth of worms and human remains.

In his perfect madness, Berserker stirred to consciousness as the shock of being summoned faded.

"Hmm? What a curious spirit you have summoned, Kariya."

The dark sanctuary that had sustained the ancient patriarch of the Makiri, now the Matou, family was filled with an unearthly roar of pure fury. In blur of motion the man with the silver hair and the re clothes sprang from his kneeling position into the air just as a pair of swords appeared in his hands. The seemingly frail old man barely managed to throw himself to the side in time to avoid being sliced in two by the enraged Heroic Spirit.

"Deactivate his Madness Enhancement, Kariya!" The withered creature commanded harshly.

For a moment the sickly man didn't react: he had held out some weak hope that perhaps his Servant might just do the world a favour and butcher Zouken like the monster he was. But then he felt the worms inside him writhe, filling his being with crawling agony as the disgusting things beneath his skin shifted.

"Kariya!" The vampire of the Matou manor insisted, forcing his descnedant to obey.

"Stop!" The man said through a gasp of pain. "I am the Master of Berserker: let the veil of madness be lifted!"

-KILLKILL I have to kill this monster!-

Berserker did not cease his furious assault in spite of the fact that his madness had been lifted: in fact, it seemed that doing so had only brought an even greater focus to the spirit. More swords of all size and shape faded into existence, summoned by the will and magic of the entity that had been summoned from across the twisted paths of time, and shot toward the cowering old man. It was only a series of quick blocks and deflections with his gnarled and hastily reinforced cane that he was able to save himself from the deadly hail of blades.

Kariya felt the worm's writhing increase as Zouken's worry grew, threatening to devouring him from the inside out unless something was done. And if he died here and now before winning the Grail War, then Sakura would find herself back in that dark pit, suffering in horrible silence as the worms crawled and burrowed and violated...

"I command you to obey me!" Kariya desperately invoked, using one of his three Commands mere minutes after having acquired his Servant. "Cease your attack!"

The effect it had on his Servant was instantaneous, causing him to freeze for a moment just as the magic took hold of him.

-This is wrong! I have to kill him! I can save Sakura! I can-

Whatever it was that Berserker had been about to think was cut off as Kariya's Command Spell forced him to obey in spite of how much he wanted to destroy the abomination in front of him. So much pain and suffering could be avoided if only... but he had to obey. There was no other option for now. For now, he would just have to bide his time and wait for an opportunity.

"Very good, Kariya-chan." The whithered creature called Zouken praised, mocking him at the same time with the insultingly familiar suffix. "It looks you might make a decent Master after all. Be sure to keep the madness out of him when I'm around, or you might be leaving this war sooner than you'd like."

The pale, sickly man made no response to the jibe. Instead, he called out to his Servant.

"Berserker, come here."

The red warrior tensed for only a second before obeying. In doing so the many swords that had been spawned by his magic vanished with a high-pitched hum as the od that powered them vanished. Berserker stood beside his Master, and waited obediantly for an order.

"What are you going to do now, Kariya-chan?" Zouken Matou asked, sounding only minutely interested in hearing an answer.

Kariya regarded the elder for a moment with the single eye that remained to him, trying not to let his intense hatred and disgust for him to show. After a year in the pits under his 'tender' ministrations, it was a lot harder than it seemed.

"We'll leave for now, and make plans of attack against the enemies we know of." He eventually answered.

"Oh? So eager to leave are you? And I thought you might be getting used to this place." The old remnant taunted, chuckling quietly to himself.

Again, Kariya ignored the jibe. Reacting to it would case the creature that called itself Matou Zouken to agitate the worms in Kariya's body, which would only deteriorate his health. And he would need every ounce of strength for this war if he was going to save Sakura.

He turned to leave instead, followed closely by the red Servant. Up the narrow staircase, through the hidden passages and catacombs beneath the manor and out the door into the night they went, neither one stopping for a second when little Matou Shinji gaped at them as they passed by. Neither did they speak a word to one another the way out: there seemed to be an unspoken agreement that all conversation would have to take place away from the Matou residence.

But soon enough they did leave that place, and Kariya found himself asking the question that had been gnawing at him ever since he had looked upon Berserker and realized that he had no idea who he had summoned, nor why he would want to kill Zouken even after the madness of his Class had been removed. An ancient hero of the Church, maybe? Or a renowned vampire hunter of some kind? There was just no knowing.

So instead of pondering the question further, he simply asked it.

"Who were you?"

Berserker smiled at that, laughing quietly to himself as if there was something funny about the question.

"You wouldn't know me." He answered wryly. "But you can call me Shirou."
