Story Start!

The final servant had been summoned.

It was go time.

"Hahahaha... so long doing nothing... this body is going to get rusty." Shuten laughed as she walked in her true clothes down the dark streets of Fuyuki. They had a destination in mind, a place that they could confirm a servant was at. The fact was that there was currently a Servant at the Fuyuki school, and that was where they were headed towards.

She was excited for bloodshed.

"Strangely... I'm not getting ANY detections of Medusa's Master at the school..." Naruto hummed in thought, annoyed since that meant the only option towards beating the enemy was their servant this time. If they killed Medusa, that would knock the master out of the game. "We can confirm Cu Chulainn, Medusa, and Future Emiya as opponents. Medusa would make a good ally... if we can get her to turn on her master all the better." Naruto stated.

More allies, meant better options for survival.

He wanted to live, and this was for all intents and purposes a death game. He was not going to hesitate to end the lives of his enemies, because almost every person who was still a Master after becoming one, did so by choice. You could easily revoke your rights as a master, so by continuing to participate in the game, you were signalling your willingness to risk your life.

"Medusa... I like that name." Shuten summoned a large sword, a sword that weighed more than her own body did, and had the size to show for it. She wielded the sword with a single hand, and she slashed open the metal bars of the school's front gate. She didn't care about the destruction she caused the school, because she was going to enjoy herself.

Naruto felt a chill.

This was his first time actually entering the school himself, but he could feel a barrier around the school that had yet to be activated. Naruto grabbed Shuten by the shoulder and yanked her back.

"In the legends of Medusa, the Shapeless Isle was surrounded by darkness, dyed in blood, and the sun didn't even shine there... the Temble of Blood. Medusa has claimed this school as her shapeless isle... if we enter the school, we are at a disadvantage." Naruto thanked the internet for that one. The second he realized that Medusa was one of their enemies, he made it a point to look up every single legend and myth surrounding her.

Shuten frowned and stared at the school, before a smile came over her face.

"So... you weren't the only Master doing some work." Shuten stated with a wicked smile. "Your barrier didn't tell you everything then."

"My barrier only lets me see images of potential Masters and Servants... fighting Medusa here would be a bad call." Naruto had wanted to either gain an ally or kill an enemy on the first night of fighting, but he guessed that was not going to happen at the school. He didn't want to fight the enemy on their home turf, where they had the advantage.

Shuten did what she wanted anyway.

She started to walk towards the school, and she looked back at Naruto.

"I'm going to have some fun Sweetie... or should I call you Master?" Shuten asked him sweetly, her words implying something.

You can't stop me without a Command Spell.

She was telling him that this time, she was not going to obey him without the use of a command spell. He grit his teeth for a moment, and her eyes widened when she saw his annoyance, and her sweet grin became sultry.

"Fine... it's a bad idea to enter their turf to fight... but damn it, stopping you right now isn't worth the effort." Naruto stepped forward and walked behind Shuten as she went towards her prey with her eyes gleaming with unrestrained malice.

Shuten would be killing tonight.

"Do not fret my Sweetie... tonight will be a good night." Shuten promised as she licked her lips, before she bit her lower lip and allowed her own blood to drip down her chin. She looked at the gourd that was connected to the handle of her sword, and she sucked the sword back into the gourd without explaining her reasoning to Naruto. The blue gourd had an allure to it, but he knew it was dangerous.

They crossed the front of the school an entered the building.

"Assassin... they are on the second floor." Naruto told her.

She pouted.

"Sweetie... I enjoy hearing you say my name... it pleases my body, my ears, my brain... to hear it." Shuten responded to him calling her by her class with disappointment. She didn't care if the enemy knew her weaknesses, since her weakness was of no concern. Her weakness was poisoned sake and then having her head cut off in her sleep.

That was not a weakness an enemy could easily exploit, and what was more she didn't care if they tried to exploit it either.

Naruto grinned.

"... Okay... Saber..."

Shuten perked up when he called her by a class that she was not, and she grinned with even more amusement at the dark trick he was playing. She started to walk up the steps to the second floor of the school with the malice turned to her gaze. She heard Naruto walking behind her, and she started to walk with much more sway to her steps.

"Sweetie... you should take off your shirt... because I will be bathing us in a delicious shower." Shuten warned him.

He heeded her warning.

He took his shirt off and tossed it to the stairs, leaving him shirtless as he walked.

"You seem sad."

"I am saddened... the moon is hidden tonight... drinking fine sake under the moonlight... with a pinchg of blue eyes reflected in the sake... it saddens me that tonight will not end perfectly... but be sure to watch me." Shuten admitted as she got to the second floor, and looked out a window to see the moon obscured by the clouds. She got to the second floor before him, and when he got to the second floor he looked in the general direction that he could feel the servant in.

There she was.

She walked out of a classroom with a man behind her.

'Her Master... but he has no command spells... but that book he is holding has the same... I see... he isn't her true Master.' Naruto thought as he looked at the high school boy that was following Medusa around.

He was a proxy.

That was why he could not sense him as a Master at the school, and why Medusa seemed to be alone. This boy was Shinji Matou, and he had such little capacity as a magus that he barely even registered to the barrier.

"Ah... seems we aren't the only ones at the school."

"Master... she is a servant." Medusa summoned a weapon in each of her hands, connected to each other by chains. They were large nails in shape, but they would serve as daggers. The fact that Medusa recognized them for a threat right off the bat showed that she was far more intelligent than the boy acting like her master.

Naruto put his hand to his chin.

"Saber-"

"Lets kill each other Medusa." Shuten's calm war cry as she rushed towards Medusa was enough to throw the servant off. Shuten reached out with her claws to rip out Medusa's heart, while Shinji yelped and jumped back and ran away from the fighting. Medusa managed to overcome her shock and block the blow from the smaller woman.

She seemed taken aback by her true name being revealed so casually.

"You might want to use a Command Spell, your Rider is not match for my Saber Shinji." Naruto warned the boy as he walked closer to the battle.

Medusa realized right away.

With their first exchange, she realized she was no match for the servant fighting her. She jumped and placed her feet on the ceiling, before she jumped again and changed her target towards Naruto himself. She knew if she was no match for the servant, then she would have to attack the master instead.

"Sakura is in danger."

Medusa stopped her attack and landed behind Naruto when he whispered those words, while Shuten seemed greatly amused by Naruto's clear bluff. She laughed and looked towards Shinji, who was now wide open. Medusa tried to appear unphased, but Naruto looked back at her, and he reached into his pocket.

A mirror.

"If you activate your eyes, you lose... and thanks for confirming that Sakura is your Master, not Shinji. I thought it was weird that I sensed nothing from him... and I bet Sakura transferred a command spell to him... as that book." Naruto showed Medusa the mirror, and she froze in place as Shuten started to walk towards the defenseless Shinji.

"Rider! What are you doing, kill him already! Come and defend-"

"Your voice is unpleasant to me... do not speak again." Shuten spoke to Shinji with a frown on her face, and her eyes wide. She grabbed Shinji by the mouth and held him off of his feet so that he couldn't run away. He kicked at her and punched at her, but she didn't so much as flinch no matter how much he attacked her.

She grabbed the book he was holding that Naruto mentioned, and she tossed it across the hallway, and it landed in Naruto's hand.

"My Master is Shinji."

"Sakura is not in danger, I planted explosives in the Tohsaka house, not in the Matou house. I just bluffed to see your reaction... I figured if Sakura was your real Master, you wouldn't attack me." Naruto told Medusa as he gripped the book and the mirror.

Medusa was no threat anymore.

With the book, he could order her to kill herself, and take her out of the competition. Shinji was an Master of no skill, and didn't even hide the book he was using to control the servant.

"Saber... you can have fun with Shinji if you want."

"Heh..." Shuten tossed Shinji to the floor, and she started toi flex her fingers.

"Rider!"

"... You are no longer my Master." Medusa confirmed with a frown, as she looked at the man who was holding the book that controlled her. Shinji got up and started to run away, scrambling to his feet and unsteadily running.

He smacked into Shuten as she appeared in front of him.

He turned and ran in the other direction, but Shuten appeared in front of him again, only this time her face was showing glee on it.

"If I'm not a Master, you can't attack me!"

"... I won't kill you yet... but I did promise my Sweetie he would be getting rained on." Shuten pushed Shinji against the window, and cracked the glass with his face. She started to crack her fingers as Shinji began to run away.

She walked after him.

She took a deep chug of her sake, before she wiped her lips. She opened her mouth, and out came a large stream of flames. Shinji screamed in pain as she belched flames over the floor, and his feet and ankles were burned. He collapsed, and Shuten just stepped on his back and pushed him into the floor.

"... Your bones and blood would make a poor sake... they almost aren't even worth collecting." Shuten sighed in disappointment.

Shinji had already been reduced to tears.

Shuten was greatly disappointed by this, and she looked at Naruto as he kept his gaze on Medusa. Medusa was unable to attack, but she no longer had the motivation to protect Shinji either. In the end, Shuten felt like she was bullying ain insect, since nobody was going to defend him.

"Aren't worth it..."

"My Sweetie's blood was as delicious as any sake... it was warm, and it so full of life... when I drank it, I felt like it would burn my throat." Shuten wiped the blood off of Shinji's face, and she ran it along her tongue.

She paused.

"Saber?"

"Not as bad as I thought... your blood is wicked, and vile... but as low of a quality as it is, it is not as low quality as I thought." Shuten corrected herself as she took her claws and started to drag them down the base os his spine. She lowered herself so that she was sitting on his back, and she used her claws to rip and tear into his spine and ribs.

Medusa was passive.

Shuten got up when Shinji's back was torn to shreds, and she grabbed him by his burnt ankle and started to swing his body around. She slammed it into the floor to wake him back up, because he had passed out. His blood went flying everywhere as she swung him, before she tossed him towards Naruto, with the boy landed on the ground next to him.

"Medusa... here is my deal for you." Naruto stated as he held the book out to her.

She walked forward.

Screams.

"A deal?"

"I swear that I will not harm Sakura at all, even if you don't accept my deal... do you want to hear out my deal now?" Naruto told her.

She nodded.

"Sweetie... watch me."

"In a minute." Naruto didn't care to watch Shuten torturing a boy for her amusement at the moment. He was trying to ignore the screams in favor of making a deal. It didn't help that blood was spraying against his body at the moment thanks to Shuten keeping her promise. "It is a simple deal... become my ally for the time being. I promise that when you and Saber are the last servants remaining, I will not attack Sakura... I will try to kill you instead." Naruto promised a horrible deal.

Medusa's frown deepened.

"Even if I don't accept this deal, you said you won't attack her."

"Because if you don't accept this deal, then I will use this book to make you kill yourself. This book is a command spell. You accept the deal, and Sakura stays safe... you reject the deal, and Sakura stays safe... because she will no longer be a Master." Naruto stated why it was a deal, and why he had no plans to hurt Sakura at all. With Shinji's single command spell in his hands, he had all of the power to just force Medusa to kill herself.

Naruto noticed something.

His magical energy was being drained by the book and transferred towards Medusa, and he looked down at it with a raised eyebrow. The amount of magical energy was barely anything at all compared to what he had, but he could sense Medusa's strength increasing. It was his magical energy while he had the book that was supplying her with the ability to manifest.

Medusa noticed him pause.

"I see... if I destroy this book, Sakura will get her command spells back... okay then... Medusa! My Command Spell, you can not attack me!" Naruto didn't wait for her before he used a command spell from the book. He looked at saw the book had not vanished. "Medusa, by order of a Command Spell, do not attack me!" Naruto ordered a second time, and the book glowed.

He strengthed the first command.

Naruto tossed Medusa the book, with 2 Commands Spells enforcing each other, she no longer had the ability to attack him in any way. With her unable to attack him, he would give her the book.

She gave it back to him.

"... I accept your deal."

Naruto destroyed the book.

"There... you are Sakura's servant again... and she still has a remaining command spell. You don't have to go back to her if you don't want to involve her, but now you will be getting supplied energy from..." Naruto turned around and paused when he saw the floor next to him. "... where is Shinji?" Naruto asked Shuten.

She smiled.

Her face was covered in blood, and she was chewing on a bone, sucking the marrow out of it. The screaming had stopped awhile ago.

"His screaming really wet my appetite."

Medusa escaped out the window, taking her spirit form and vanishing.

"Are you sure it is okay to let her go?" Shuten questioned him.

He just nodded.

"Medusa actually cares about her Master. She would die for her Master... she didn't deserve to die as the servant of a fake Master. We will kill her when the time comes... but until then, she is an ally." Naruto wanted an ally for potentially powerful servants, and Medusa was that ally he could use. In the end, she was still a future enemy, but with the power of 2 command spells having been used by the book, she could no longer pose a threat to him.

"I notice you didn't tell her not to attack me."

"Because... I bet you want to fight her, and kill her yourself. You wouldn't be happy killing her if she couldn't attack you." Naruto could tell that Shuten was smiling at his statement.

He was right.

She would have been very disappointed if he took away her fun, and killing Medusa would be very fun for her in the future.

"Sweetie, you do so ever gently spoil me... but you are very soft hearted."

He could have taken away her free will and done so many things to Medusa, but the only thing he did was make sure she could not attack him. In the end, she could see herself enjoying herself with this man as her master.
