Story Start!

"You know, even if we follow Raynare, this is in bad taste." A young adult male spoke as he could heard the sounds of a party with all of the other Rogue Priests inside of the Church. They all followed Raynare since she had promised many of them a way back into the good graces of the church, or if she couldn't manage that, at least a way they could keep killing Devils without having to worry about the consequences.

All at the sacrifice of a single nun.

Raynare would achieve her goal of becoming more powerful, a better person to use for combat by Azazel and Shemhazai the leaders of Grigori that she practically worshipped. She was given the mission to watch over Issei Hyoudou, and she killed him, she plotted to steal Asia Argento's Sacred Gear behind Azazel's back without his orders, and she succeeded in getting a Sacred Gear of her own. Now she just needed to complete her last mission and cause stress to a certain Uzumaki child.

"Ah, let her party, she won't get much more of this. After all, after this she needs to go back to her current mission." The second Rogue Priest guarding the church stated. Since Raynare was celebrating, she was afraid of attracting the attention of the Gremory and Sitri heirs that were in the area. Her boost to her combat abilities aside, she wasn't able to fight either of those people in a fair or unfair fight.

Mist started to appear in the area, but neither of them paid attention. Mist wasn't anything that unusual after all, they just kept their guards up.

Silence.

"Dude?" The Second Rogue Priest asked when he got nothing in response to his statement. He looked over at his friend of 6 years now, only to see him slumped over on the ground with a knife sticking out of his neck. He felt pain in his own neck for a brief moment, but with surgical skill, his throat was slit in such a way that he couldn't even gurgle out a scream or make one noise at all. In seconds, he was slumped over on the ground as well.

Jack was standing behind him.

She was smiling a childish smile, before it turned into a malicious smile at the drop of a hat. She grabbed both of the bodies by the backs of their cloaks, before she started to pull them towards the forest. They were already dead, so she threw them into the bushes and just giggled to herself.

"Good work Assassin."

"We did a good job Mommy?" Jack asked as she walked towards Naruto, hands behind her back as she leaned forward to get praised. Her orders were very simple, kill absolutely everyone who was involved in the murder of the blond haired girl that her mother was fond of. She was aware of what Naruto did when she wasn't being summoned if it caused him stress, and she knew that when the people at this church were going to do a ritual to bring Asia into the church, that Naruto was suspicious of something.

Naruto reached out to rub the top of her head, but his face didn't hold a drop of affection in it at the moment as he stared at the doors of the church. The last place that he had seen Asia alive was in this church, and it was the people here that killed her.

Ritual.

Asia had a ritual done to her at this church, and she had her Sacred Gear stolen that ended with her death. It was easy for anyone to put two and two together.

"Don't let anyone escape this building now. If anyone tries to enter or leave other than me, kill them all without mercy Assassin." Naruto stated to her his very clear orders. He didn't know why he summoned a loli for an assassin, but her skill was without a doubt worthy of the title. The way she killed the two door guards had been without a doubt flawless. Neither of the guards knew what hit them before they were dead, perfectly silently, perfect target choices, and merciless kills.

Jack smiled.

"Mommy can call us Jack, Jack the Ripper. We're the Assassin that Mommy summoned after all, you deserve our true name." Jack spoke, having no problem revealing who she really was. Knowledge of a true name was deadly, and could provide enemies with an extreme advantage if they were aware of their weaknesses. Thankfully, she was Jack the Ripper, a historical figure that was nothing but mystery, with no known weaknesses. "You know, we can slaughter them all for you inside. We would love to bring them hell for making Mommy upset." Jack spoke with worry in her voice.

Naruto's hands were shaking with murderous rage.

"There will be those that will try to escape, you won't let that happen though. If you're my servant, I can put my absolute faith you won't let even one person escape tonight." Naruto stated, since from what he understood he summoned her because she was the assassin that he would have the best bond with. That was what his Sacred Gear explained to him as he read some of the tips on summoning the Assassin servant that was detailed in the summary of Jack and her abilities.

Jack smiled and nodded her head, hopping in place.

"Nobody will escape our eyes, we will do whatever Mommy asks to make him happy!"

"Good girl Jack, good girl. Now... let me ask you this... how long can you torture a person before they die?" Naruto asked Jack with a dangerous glint in his eyes.

"A long time."

"Good answer." Naruto responded to her response, and with that he opened the doors of the church and walked in. Jack smiled at him and waved, knowing that she was going to do a good job in not allowing for any survivors.

Naruto was surrounded the second he stepped foot in the Church.

He was face to face with over 30 Rogue Priests.

"Ah, Naruto! You must have come to admire my handiwork, sorry, but it seems that your little girlfriend didn't get to come to the party!" Raynare, in her true Fallen Angel form, exclaimed as she held out her hands tauntingly. She might have been surprised to seem him for a moment when he opened the door, but that surprised turned into glee.

What a perfect day.

She started the day by killing Asia before the sun rose, then the rest of the day practicing with her new Sacred Gear, and now that night had fallen she could complete her mission given to her by Azazel and cause this boy more suffering.

Naruto's response got raised eyebrows.

He took off his shirt and exposed his bare chest.

"I'm going to kill every person in this room, and you are going to suffer for the rest of your life Raynare. You will beg and plead for death to come, but I will not allow it to ever kiss you. Asia was the most innocent girl I've ever met, and you killed her for your own selfish reasons. You will suffer and face every humiliation that I can think up and more. Take your shot, it will be the only shot you get at me." Naruto gave her a single warning to what was about to happen to her and every person who was currently in the room.

He was met with laughter.

"He thinks he can take us-"

Naruto punched the person in the face who started to speak, he just ran full force at him and smashed his fist into his face without holding any of his strength back. The laughter stopped just as quickly as the man's life ended.

Raynare caught a head that went flying at her.

"Ah... ah..." Raynare looked down at the man's head in her hands, while Naruto stood up straight and extended both of his arms out. Her eyes widened in shock, and she dropped the severed head when she realized that Naruto had just punched the man's head clean off his shoulders. His face, which had once had recognizable features, had caved into his skull as well, and parts of his spine were coming from his neck. "A-attack!" Raynare shouted at her men.

"If any of you try to leave this building, your death will be less painful, but just as merciless as that. That your best shot at me now, you've crossed the line with me, so this is your only chance to kill me." Naruto extended his arms and walked across the room. There was no laughter or glee in the room anymore, and nobody could take Naruto anything less than completely serious.

Naruto caught a sword with a blade made of light, and his hand started to bleed from the bladed weapon. Naruto pushed the sword into the man's face, before he ripped it downwards and split his throat open, and cut his torso up, guts spilling across the floor.

Naruto glared back at Raynare, and she flapped her wings to fly away out of a window.

Naruto grabbed the new corpse and threw it at her the second she took flight, knock the full weight of an adult man against her stomach and bringing her out of the air.

"I have other Fallen Angels... they'll be back any second when they are done patrolling the area. My allies will kill you if you touch me... so... just leave this church and we can forget this happened." Raynare gave Naruto a warning.

"More corpses to the pile."

"I'm out of here!" A Rogue Priest with no real loyalty to Raynare shouted as he ran towards the front door, Naruto made no move to stop him. The second he took a single step outside the door, a knife slit his throat, and he collapsed as the door closed behind him, sealing everyone in the room again.

"The word of a King is final. The King has the power of both a Judge and a Jury, every person here is guilty in the death of Asia Argento, and I have sentences all of you to death. The only chance you have to live is to kill me, leaving this building is instant death. Who wishes to fight their sentence?"

-Outside-

"Aaaaaah, now that is a sound to hear, Mommy's anger is like a calm ocean of blood." Jack spoke to herself as she put her ear up against the door. She was so happy that her master was willing to take the lives of those who crossed him in the worst ways, though she wished his heart was more black. Even right now, his anger was simply justice for the sake of another person. If only he was a serial killer who killed for the sake of killing, then that would be even better.

But he was her mother, so she was happy just being with him and following his orders.

"Woah... sounds like something horrible is going on inside there. Hey, little loli whore, if I went in there... what would my chances of living be?" A white haired man asked as he gestured towards the building, where screams of pain and fear could be heard. Jack tilted her head, and she looked into his red eyes, before she took a couple of steps backwards.

She vanished into the mist.

"If you try to enter the building, we will kill you now."

"Ah... well, then I'm going to go that way, I don't care of that bitch dies. My Master is somebody different anyway." The man turned around and walked away. He blinked a couple of times, before he noticed that she was standing behind him with her blade pointed at his neck. She smiled at him innocently, before it became deadly.

He judged his chances.

Not good.

"... You can go." Jack stated as she allowed the man to go free after giving it a moment of thought. She had to think about what Naruto told her, but if the man wasn't going to enter the building, then she would be going against Naruto's orders on who she was suppose to kill. "You didn't kill a blond bitch named Asia Argento, did you?" Jack asked the man, since that answer would change if she had to follow orders.

Mommy would be happy if she killed a guilty man.

"Nope, I was out killing people who made contracts with Devil scum, but man would it have been fun to watch her die. Alas, killing people myself is far more fun than watching somebody else bite the dust." The man spoke honestly and easily enough. Jack frowned and she lowered her knife and stepped to the side to allow him to leave.

"You can go to hell... we have no issues with murderers." Jack allowed the man to pass after his answer satisfied her.

"Name's Freed Sellzen, tell your Master that-"

Jack smiled as she twisted the knife that she had, right into Freed's spine the second he passed her. He collapsed onto his belly, face hitting the ground, while she got on his back and started to drag the knife up his spine.

"YOU BITCH, YOU LIED!"

"You can go to hell, we can smell the scent of a woman on you. You came in contact with her corpse, so we will make Mommy happy by ripping you to pieces." Jack figured that she could kill any person who had contact with Asia though. She smelled Asia on the man, meaning he had contact with her corpse. Touching the corpse was practically the go ahead to kill him. "Oh, by the way... from one serial killer to another... we told you from the very beginning that you can go to hell. It's your fault for not drawing your sword." Jack smiled wickedly.

Her words and body language didn't always translate to the same thing, just because she moved to the side to allow him to move, didn't mean her words had no meaning to them. She told him that she was going to kill him and send him to hell, it was his fault for thinking that she was letting him go free.

He was already dead by the time her knife got to his neck.

"So, you're Naruto's Sacred Gear..."

"Our orders are to kill everyone who tries to enter the Church, or leave it. So, we suggest that you not step any closer if you want to live much longer." Jack looked up from the fresh corpse she created, and saw Rias Gremory walking towards them. Behind her was Koneko, and Issei carrying Asia's corpse in his arms still.

The second she had been summoned, Naruto stormed off and left Koneko and Issei behind without explaining anything to them. Issei was protecting Asia's body like his life depended on it though.

"... Actually, you get a free pass." Jack pointed at Issei, since she was sure Naruto would be very mad if she killed him. "You two don't though, we'll kill you if you come closer." Jack informed them with a wide grin.

The screams in the church started to grow more silent.

"I'm here to speak with Naruto. My dear servant Issei here brought me Asia, to see if I could save her. She hasn't been dead very long, so I'm sure that if Naruto got her Sacred Gear back, I could revive her for a price." Rias spoke as she made the offer to Naruto's Sacred Gear. This wasn't her plan, and she didn't even really know who the hell Asia was, but it was very clear that she could make Naruto happy and add him to her peerage at the same time.

The screams started to get more silent, before they stopped.

"Ah... no more screams, Mommy is done." Jack whispered when the very last of the screams stopped. She stood up off of Freed, and she walked towards the church.

She opened the doors.

Red.

Issei felt the urge to throw up when he saw blood splattered everywhere, like the inside of the church had gotten a new paint job done very poorly. Naruto was standing in the middle of it, with a spear of light pierced through his shoulder as he stared down at a broken woman on the floor, who was still breathing.

Her face was unrecognizable.
Her arms and legs were bent in the wrong directions, the bones visible broken.
Her chest and ribs had indents of his fists in them, and she had chunks of her hair ripped from her skull.
The ring fingers on both of her hands had been ripped off, and Naruto was holding the Twilight Healing in the palm of his head.

"K-kill me."

Raynare the Fallen Angel was still breathing, still alive despite how much she was wishing that wasn't the case. Her teeth, every single one of them, had been knocked out of her mouth so she wasn't even able to bite her own tongue to end her suffering. Naruto reached down and grabbed her by the face, lifting her up into the air, and he squeezed until there was a crack.

She broke her skull, but he only broke it enough to cause suffering, not kill her.

"No, you killed somebody important to me, your suffering has only begun. I'm going to make you experience the pain you put Asia through when you betrayed her trust. When she was kicked out of the Church, you offered a hand to her... Asia really believed in you, and you took advantage of her and killed her. The pain I've put you through is nothing compared to what you did to her heart." Naruto stated as he tossed Raynare towards Jack, since he had heard the door opening up. She caught Raynare, and she smiled in appreciation.

"You did all of this... for Asia?" Koneko whispered in shock when she saw the horrors that Naruto committed.

"Have fun Jack." Naruto told his servant with a glare at Raynare. "Keep her alive as long as you can, she mentioned other Fallen Angels were her allies. I won't be done until everyone who hurt Asia is punished." Naruto walked passed them.

Rias didn't stop Naruto.

"If I could save Asia, would that be worth your soul?" Rias asked Naruto as he passed.

"I would pay 100 times that much to see her eyes filled with life again." Naruto didn't hesitate to state. "She's my precious friend, I would pay any price in the world for her." Naruto was no less angry that Asia had been killed.

Hope appeared in his eyes though.

"I'll be waiting for you at the school then, and if you give me the Twilight Healing, Asia will be waiting for you there as well. She needs to be complete in order to bring her back. I approve of what you did, if anyone touched my servants, I would do this as well." Rias could appreciate that Naruto was willing to do all of this for one of his loved ones. It actually made him much more understandable to her.

Naruto tossed her Asia's Sacred Gear.

"If Asia isn't alive when I get to the school building, nothing will save you from me."

Naruto's threat stated, he walked off.

He had some Fallen Angels to track down.

Chapter End!
Please Leave Me Lots of Nice Long Reviews, But No Flames Please!

Even in canon (Before Naruto's goal became peace), the only times we have seen Naruto go into murderous, blood thirsty rages, are when his loved ones are hurt or killed.
Naruto, even canon Naruto, would not hesitate to murder people who hurt those precious to him.
