Got the next chapter done! It sticks to the original story a bit more than I want, but I'll be changing some thing in the chapters to come. Hope you all enjoy.

"Naruto, have you concluded your business here" Saber asked once Naruto and Rin exited the church grounds. "Yeah" Naruto told her. "And?" Saber asked. "Do you have to ask? I'm going to fight in this war! Thou I hope you don't mind that That I'm a shinobi instead of a magus" Naruto told the knight.
"I have seen for myself that what you lack as a magus, you make up for in your skills as a warrior. I am honored to have you as my master" Saber told her fellow blond. "Then we'll fight as a team" Naruto said as he held out his hand. After a moment Naruto asked, "Isn't this normally where we shake hands?". "Yes, of course. I just wasn't expecting it. So it surprised me a little" Saber said before taking hold of his hand.
"You know lord Hokage is going to be upset when she finds out about this" the three heard, getting Saber and Rin on alert. "You done giving your report to Baa-chan?" Naruto asked with out looking for the source of the voice. "I got back as you were leaving the house" a woman with long purple hair, gray armor over skin tight black clothes, a katana sheathed on her back, and a white mask in the shape of a cats face, said as she appeared on the stone wall next to them.
'Assassin?' Saber and Rin wondered as they prepared for a fight. Seeing the two on edge Naruto decided to introduce them. "Rin, Saber, this is Yugao. She's been assigned as my guard since I was a kid" Naruto said as Yugao dropped down.
"Guard?" Rin asked. "Yes, ever since Naruto started living in this world" Yugao told the girl. "Sorry for being on edge. You resembled a servant class" Saber said as she lowered her sword. "I see. I'll need a detailed description of servant classes, but that can wait until we get back to the house" Yugao said as she vanished from sight. "Come on. Let's get going" Naruto said as he started walking back to his house.
Later
After some time of walking, Rin stopped in the middle of the road. "Something wrong Rin?" Naruto asked.
"No offense, but go home by yourself" Rin told him. 'Does she expect me to take a longer path to my house? I guess I could always use the roofs, but I don't think she knows I can do that' the blond thought. "I brought you here because you weren't officially my enemy yet. But now you're a fellow master, Emiya" Rin said as she turned to face the blond.
"I don't plan to fight you unless you attack first" Naruto simply told her. "I should've figured. Why did I even bring you here?" Rin asked herself as she lightly facepalmed.
"Rin" Archer said as he materialized next to Rin. "What?" Rin asked. "You should be fortunate that he isn't willing to attack. Not only has he summoned Saber, but he was also able to hold off Lancer in a fight, and has a protector with the concealment abilities of an Assassin" Archer told her. "I'm aware of that" Rin told him with some annoyance in her voice.
"Perhaps you do not wish to fight for a different reason" Archer inquired. "O-of course not!" Rin told her servant with a small blush. "It's just, I owe him, you know? And I can't fight with a clear conscience until I repay him" Rin said as Naruto, Saber, and Yugao watched the two have a conversation. "Hm, making things difficult again. In that case, call me when you have repaid this debt of yours" Archer said as he returned to spirit form.
"What debt are you talking about?" Naruto asked. "You saved me from Saber, remember? I just don't like being indebted to someone" Rin told him. "If that's all then you do-" Naruto was saying when his eyes widened and both he and Saber turned around.
"So, are you done chatting?" a little girl with red eyes, white hair, and a purple coat and hat asked as she stood next to a towering behemoth of muscle. "Berserker" Rin said with a worried expression.
"Good evening, Onii-chan" the girl said before she took a few steps forward and did a curtsy. "It's nice to meet you, Rin. I'm-" the girl was saying when Naruto appeared in front of her faster than both Rin ans Saber could see, and pulled the girl into a hug. "Illya!" the blond happily cheered as he lifted the girl up ans started spinning.
"Do, do you know what's going on?" Rin asked with a stunned expression. "I do not" Saber answered with her own stunned expression.
"Aaahh! Onii-chan, I'm getting dizzy!" Illya told the blond while he spun her. "Oh, sorry! Guess I got to excited" Naruto apologized as he put the girl down. "W-why did you just hug me?" Illya asked as she tried to get her barrings. "What, aren't I allowed to hug my own sister?" Naruto asked. "Sister?!" Rin nearly yelled.
"Yeah, me and old man Kiritsugu tried to get her from the Einzbern countless times, but we could never get close to her. I was going to make another attempt next month" Naruto said just before Yugao grabbed him and pulled him back to the others to keep him from being crushed by Berserker's massive sword.
"Whether she's your sister or not, she's our enemy at the moment" Yugao said as she put the blond down. "Right, forgot about that" Naruto admitted.
"We wont be able to take that thing head on" Archer said while he was still in spirit form. "Archer, you should use your class's usual methods" Rin told Archer. "What about defense? I doubt you could stop it if it charges" Archer stated. "There's four of us. We'll be able to hold him off at the vary least" Rin said. "Understood" Archer said before he took off.
'Kiritsugu tried to get me' Illya thought as she watched the others talk. 'No! It has to be a lie! Kiritsugu abandoned me!' Illya thought as she shook her head. "Are you done talking? Can I get started now?" Illya asked. "Okay, I'm going to kill you now. Get them, Berserker" Illya said when no one answered her.
At Illya's command, Berserker's entire body took on a red appearance just before he jumped towards them. "However, Berserker was struck by a volley of arrows that sent him into a grassy area that overlooked the city.
"No way! They have no effect!" Rin said in shock as they saw Berserker in the small crater without a single scratch on him. "We'll just have to keep hitting him then" Naruto said, just before Berserker closed the distance and went to kill the blond with his sword. 'Shit' Naruto thought, having no time to counter. However, Berserker's sword was stopped by Saber, the force of the blades knocking Naruto back.
After drawing their swords back, Saber swung again, knocking Berserker back. Berserker roared as he stood back up, just before Saber rushed as him and the two began their attack again.
"I'm not going to just stand here" Naruto said before he started running towards them. "Emiya, What do you think you're doing?!" Rin yelled as the blond formed around two dozen clones to attack Berserker. "I'm being a detraction if nothing else!" Naruto yelled back as a quarter of his clones wee destroyed by Berserker's swings.
"He's powerful" Saber said after she jumped back from Berserker after a few minutes of clashing swords and a second batch of Naruto clones were devastated. "Got any ideas?" Naruto asked as he landed next to her. "Not really, but I need you to have my back" Saber said before she took off towards Berserker. "Right behind you!" Naruto said as he made another group of clones and followed her.
After a few swings, Saber dodged Berserker blow as he swung downwards. Seeing a chance, Saber slammed her foot down on the massive blade sending it further into the ground so that Berserker couldn't pull it our right away. The knight went to cut the behemoth's neck, only for Berserker to bend backwards out of the swords reach. Berserker was about kick Saber as he back flipped out of her swords path, but one of Naruto's clones pulled her out of the was. Taking the hit himself.
"He's too agile! How does that thing qualify as a Berserker?!" Rin complained. "It must be a Heroic Spirit of some renown. Even in madness, his sword skills are not dulled. I cannot help but be impressed" Saber calmly said.
Getting annoyed with how strong Berserker is Rin gave Archer and order, "Archer! Fire support!". Seconds after Rin said this, an arrow came strait for the enemy servant and exploded. Berserker never trying to dodge. Once the smoke cleared, Berserker once again stood without a single scratch on him.
"What's it take to hurt this guy?!" Naruto asked as Berserker started running towards them. After smashing through more of Naruto's clones, Berserker slammed his sword into Saber's which sent her flying. While in the air, Berserker jumped above her and kicked her into the ground.
"Saber!" Naruto yelled in concern as she blocked another strike from the servant. "It's over. Crush her, Berserker" Illya said. "Never!" Rin said as she ran over to them. "Archer!" Rin said as she threw several gems over Berserker, which shattered and formed a dome restricting Berserker's moments. After this happened, a number of arrows came and lodged themselves in Berserker's back before exploding.
"Doesn't Archer have a stronger attack?!" Naruto asked when the smoke cleared to show Berserker still had no injures. "Fighting him here wont work. We need to move to a better area" Yugao said. "Follow me. I think I know where we might stand a chance" Saber said before she took off in the direction of the church. "Yugao, keep an eye on Illya. Make sure she doesn't interfere in the fight" Naruto told the Anbu member before he took off after Saber.
Church graveyard
"Just running from this guy takes effort" Naruto commented once he and Saber lured him into the graveyard. "It'll be worth it. With your clone ability and the cover in the area, we should be able to get past his guard" Saber said as the saw Berserker enter the graveyard. "Let's put it to the test then" Naruto said as Saber went in to attack.
Using the gravestones as cover, Saber was able to reduce the amount of time Berserker had to anticipate her strike and managed to cut his chest. 'Looks like it works. Now I just need to help' Naruto thought as he made more clones.
Woods next the the graveyard
"Gosh, you scared me, attacking without warning? What are you, an animal Rin? Or is this the Tohsakas' way of fighting?" Illya asked after she'd blocked all of the magic blasts Rin fired at her. "You're the one who announced that the fight had started. There are no sneak attacks once the battle has begun. Or are you going to introduce yourself again?" Rin asked.
"Introduce myself? I might consider it if you were Onii-chan, but I don't feel like it with you. I have no interest in you. Besides, what do you want me to say to someone who is going to die here?" Illya asked Rin, just before Yugao dropped down and cut up the birds Illya had made from her hair.
"You wont be killing anyone today" Yugao said as she held her katana at the girls throat. "Surrender" Yugao ordered. "Looks like someone interesting wants to play" Illya calmly said as two more familiars formed from strands of hair, forcing the shinobi back.
"What was that?! Why didn't you take her out?!" Rin demanded to know. "Naruto would be devastated if she died. I'm limited to non-lethal attacks at the moment" Yugao told her. "Just great" Rin said as Illya formed two more familiars to make a total of four. Rin fired several more shots at the birds, only for them to intercept the shoots and return their own.
"We can't get close with those things firing at us" Yugao said before she grabbed Rin and jumped away.
Graveyard
"We have neither desire to converse, nor freedom to name ourselves. Our intercourse is limited to blows meant to kill each other. Very well, I shall answer you with a blow with all my might. Here I come. This is where you die, Berserker!" Saber said as Yugao and Rin came onto the sight of their fight. Racing towards the servant and blinding speed, Saber moved past the ground thrown up by Berserker's sword as she thrust her sword at the behemoth.
Seeing this, Berserker stopped her sword from skewering him by letting his hand be impaled instead. However, Saber focused her power threw her sword, releasing a blast of magic that cut threw Berserker's chest killing him and momentarily revealed her swords form.
"Saber, you okay?" Naruto asked as he walked over to her. "Yes, I am fine" Saber responded.
"Huh, Archer? What do you mean, get clear?" Rin asked from her spot next to Yugao. "That was magnificent, but not enough" Archer said as he formed a sword with a spiraled blade.
"Regeneration? No, that is almost like rolling back time. The curse of resurrection. A Noble Phantasm that activates upon his death!" Saber said as Berserker came back to life. 'what the hell?' Naruto questioned as he got a weird feeling. 'Whatever it is, it can't be good' Naruto thought before he grabbed Saber's hand and got them out of there just before Archer let lose his Broken Phantasm. An attack that liquefies the ground around Berserker when it hits and causes a massive explosion.
"It survived a rank A Noble Phantasm without a scratch" Rin said in disbelieve. "Naruto, what was?" Saber questioned. "Archers arrow by the looks of it" the blond said as he watched the broken sword handle that fell in front of them vanish.
"I've changed my mind about you, Rin. Your Archer is impressive. That's enough. Return to me Berserker. I'd hoped to get the boring stuff out of the way first, but my plans have changed" Illya said. "Wait, you're running?" Rin asked. "Yes, I changed my mind. I don't care about Saber, but your Archer has piqued my interest. So I'll let you live a while longer. Okay, bye-bye. Let's play again sometime, Onii-chan" Illya said before her and Berserker left.
"Master, thank you for saving me from that attack, but could you let go of my hand now?" Saber asked. "Oh right! Sorry!" Naruto said as he let go of her hand and started rubbing his head nervously. "'Do not act so carefree. You didn't get out of that unharmed'" the voice of the giant nine tailed fox sealed inside of him said. 'What do you mean Kurama?' Naruto asked just before he started coughing up blood. 'Oh. That's what you mean' the blond thought before passing out.
