"Damnit! Damnit, the Church brat was killed, and the other one escaped! If the Three Factions aren't all present, killing the Gremory and Sitri brats won't spark a new Great War, it will just spark an Underworld Civil War!"

Kokabiel was pissed off.

He had stolen the Excalibur swords to fuse together purely for the sake of creating a weapon, and drawing the Church to Gremory territory. He had put so much work into his plans, he even stole 3 of the Excalibur Swords for the sake of it. That alone put a massive price on his head since he purposely made it known he did it.

He had no place at the Grigori.

The allies he had brought together, all of them were useless to him if he was going to have both the Church and Grigori after him. The Devils had no stake in this, and since he was a Fallen Angel he was unable to wield a Holy Sword himself. Even if he killed the Gremory girl, without using the Holy sword to do it or having at least some holy sword wounds on her body, he could not pin the blame on the Church for it. He could not make Lucifer or Leviathan enraged and target Heaven and the Fallen Angels.

"Well, this is unfortunate. Another Great War would have been excellent for pushing more Sacred Gears to Longinus Level. It's truly a disappointment, but look on the bright side. We still have... where did they go?" Satanael asked in surprise when he looked in his case for the three Excalibur swords.

They were not there.

Actually, his case holding them was not there anymore.

Kokabiel's head exploded in front of Satanael moments later, as a extremely fast object came flying at him from outside of his sensing range. Only the top of his head exploded, taking out his eyes and everything above that point. The fast object came flying through the side of his head, exploding his eyes from his skull, and then came out of the other side as the top of the head exploded from the force.

...

"Well, this is even more unfortunate, it seems that out movements were not nearly as stealthy as we would have hoped." Satanael smiled to himself as he looked around with his sharp eyes. He could see things easily 4 km away no problem, but whatever had thrown that object had to have either been hiding within close range excellently, or was out of the range of his ability to see or sense.

Satanael knew that if he moved too quickly that he would be the next target for whatever had been thrown. So, instead he raised both of his hands up to show that he wasn't going to try anything.

"My name is Satanael, and I just wish to examine what killed Kokabiel, I am a scientist and have no plans on starting a conflict now that my superior is dead." Satanael made his intentions clear. He voiced them and used his lips to very clearly make each word plain, in case the killer was in either attacking range still, hearing range, or could read his lips at the moment.

He walked over to examine the object that killed Kokabiel.

Satanael raised an eyebrow when he saw a small chunk of cheese laying on the ground, covered in blood and brain matter.

Cheese.

"Chhupri, perhaps one of the hardest cheeses in the world. Harder than a rock, and when thrown with a sling by one with great aim and arm strength, it can pack enough force to shatter even a Fallen Angel's skull." Jack spoke as she made herself known to Satanael. She walked towards the cheese and picked it up, before she shook the brains off of the cheese.

Satanael looked at her, before his eyes widened a bit in recognition.

"Well, imagine my surprise. It's been awhile since I saw your face, England's Jack the Ripper. You might not remember me, but I researched how you were born. To think that tens of thousands of aborted souls could merge to form a living human. You were certainlya fascinating being in your life." Satanael had been curious about Jack when she had been alive, so he had done everything he could to find out her origin. Her abilities as an Assassin were top notch, to the point that anyone who was unfortunately her target was bound for an early grave if they didn't know she was coming.

She was just that good at killing, even if she only killed 5 women while alive originally, her sheer talent for murder was unmatched.

"We don't remember you, we're just here to-" Jack took out a camera and took a picture of Kokabiel's dead body, and took another picture as she held the cheese up in front of the camera with the dead body in frame. She had been ordered to locate the Fallen Angels in the city, so she located them and gave Naruto the information on their location. "-get proof of the kill. Just letting you know, Mommy has no problem with there being a war in the Underworld, a Civil War... but he wants you to leave Heaven out of it. Mommy sent us here, also to deliver a message those that seek conflict without purpose have no place in the world." Jack gave the message given to her to give to the survivor.

"Uzumaki Naruto, your Master, current owner of Azazel's Artificial Sacred Gear turned True Sacred Gear. A pleasure to see it in action for myself, and I see you have already gotten your hands on the Excalibur swords. Recently, as his magical power has grown out of control, he has been getting exponentially stronger. It's as if his magic is preparing his body for something big... even Kushina took over a year to be able to summon more than just Saber at one time." Satanael could sense another source of magic nearby.

Azazel kept a close eye on Naruto's growth, including how as a human, his growth had been stunted by his human body. The boy had a limit on how strong he could grow as a human, because his magic refused to allow him to experience true growth. Once he became a Devil, it had been like all the years of training had magically started to pay off as his true strength began to get revealed.

Azazel never shared any secrets of the Uzumaki with other Fallen Angels willingly.

"Yes, that is our Mommy... and yes, Mommy's magic has grown a lot. We and Mommy's other children (Read: Servants) have been trying to suck as much magic out of him as we can. Sadly, Mommy loves the witch woman, and his love for her has caused his magic to grow faster than we can suck it from him. Oh, we forgot... you have 5 minutes to leave Kuoh before Mommy takes another shot." Jack stated as she showed 3 fingers on her hand to Satanael.

He raised an eyebrow.

"... You're holding 3 fingers."

"The countdown started the second we showed up." Jack stated, since it didn't matter if she delivered the message or not, the countdown had already started. She had been visible for 2 minutes now, which gave Satanael only 3 minutes to escape the city before he suffered from a cheese death as well.

Jack gave Satanael a thumbs up.

"It will take me about 1 minute and 20 seconds to escape the city, I have time. Both of your eyes were green, but now one of your eyes is blue... I see, so your Master is using you to take aim." Satanael stated when he saw Naruto's eye color replacing Jack's left eye.

-With Naruto-

"Show up in my country without my permission, try to start a war here will you." Naruto stated with his left eye green. He was using his connection to Jack to switch their eyes magically. He was using her left eye in his body, and his eye in her body. Using the split view, he was able to far more accurate pinpoint the exact spot to aim.

Naruto loaded another chunk of cheese into his sling and started to spin it over his head. The second the countdown was done, he was going to unleash his cheese and kill the second Fallen Angel. Once he murdered Xenovia, and Rias brought her back, he summoned Jack to search the city for the Fallen Angels. He gave her an "about" location of where he sensed the Excalibur swords, and sent her out to find them.

He did it.

He murdered the legendary Kokabiel, with a piece of cheese to the head using a sling to throw it.

"Jack, look with my eye slowly to the left. My aim will be off if our eyes don't line up." Naruto stated to her. He needed to examine the area with more detail, now that the enemy was on guard for another cheese throw.

Naruto was super happy he actually killed a Fallen Angel with cheese.

Was it a fight?

Nope, what Naruto had done was assassinate a man using cheese. Naruto didn't much care for the fact of killing a person without giving them the chance to fight back, but he wasn't strong enough to kill Kokabiel while also protecting the city. The only method he could use to kill Kokabiel would be to use Excalibur, and he was NOT able to use the sword inside of the city without causing massive destruction and loss of life.

Satanael looked Jack up and down.

-With Jack-

Satanael looked Jack up and down.

"Truly, your beauty as a killer is only amplified by the fact that you are now part of a Sacred Gear. Small, unassuming, but surprisingly fast and strong. Still, you're not quite yet at the Level fo Longinus. Well, as a message to your Master, that 4 of your Mother's Servants still exist on this world. Her Sealed Caster, her Lost Rider, her Banished Berserker, and her Stubborn Lancer are all still alive." Satanael gave a warning and a surprise to Naruto. Either Naruto would read his lips, or Jack would give out the message.

...

"Impossible, Servants vanish when the Master dies... we depend on them for a supply of energy." Jack stated clearly.

"Merlin was sealed away, and his body is being fueled by the Uzumaki vault. Kushina saved up a year's worth of her magic, and transfered it all to Astolfo so he could go on an adventure... he still has several months of magic remaining. Kushina refused to allow Lancelot to kill Saber, so she forcefully attached his magic to the Earth with the command to never appear in front of her again... and that Lancer is fueling herself with power she steals from humans. Once your exploits reach the ears of Lancer, Rider, and Berserker they might come for you. A fair warning." Satanael stated as he bowed to Naruto (using Jack as proxy), before he revealed his wings and started to fly away.

-With Naruto-

'... Mom's servants, some of them are still around. Lancer refused to tell me who my Father was... but one of them will have the answer.' Naruto thought to himself as he stood up straight, and allowed the Fallen Angel to escape. "Jack, bring the corpse back, there might be a use for it." Naruto stated his order.

He had a lot of thinking to do.

Also, he wanted to show off the corpse to the others.

He murdered Kokabiel with CHEESE!

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

Kind of like with Canon Naruto, everything Naruto's parents leave behind from him ends up causing him more and more trouble.

Merlin
Lancelot (Berserker)
Astolfo (Rider)
Elizabeth Bathory (Lancer)

Kushina unknowingly let behind 4 of the most troublesome servants for Naruto to have to deal with.
