Chapter 17: Camp Jupiter

(Akatsuki Hideout)

"Zetsu, did you find anything?" Pein asked the spy of the group. It's been months since they've formed an alliance with the Titan, and ever since, the Akatsuki started studying the geography and history of the US, along with several other countries. Pein wasn't surprised to hear that humanity is destroying each other here, and only strengthen his goal for the world to have peace through pain.

"There is one thing I spotted at California." The white Zetsu spoke. "It seemed that the former Nine Tailed Jinchuriki is there, going to the camp known as Camp Jupiter."

"He's with three other demigods." The black Zetsu informed. "And two Leaf ninja squads, a Rock ninja squad, and a Cloud ninja squad are following him. It seems like all of them are going to try to capture.

Pein nodded in understanding. From what he heard, they won't be able to capture him, but they need to be prepared for if the Akatsuki need to find out where the tailed beasts are at. "Keep an eye on them." Pein said to the spy. "When the squads have been dealt with, inform Hidan and Kakuzu, who will be going to that camp."

"Oooh, that sounds fun." Hidan said eagerly. "I can get more kills for Jashin."

"And maybe there are some ninjas with bounties." Kakuzu said, mainly to himself.

"So you all know your assignments?" Pein asked everyone. They all nodded. "Good. You're dismissed." With that, all of them disappeared.

(California)

After a long walk in the tunnels, the group finally got to the door. "So, is this it?" Piper asked looking at the door. Naruto shook his head.

"We still got a long walk ahead of us, but we are close." Naruto said, ignoring Leo's whining about the long walk. The blonde then push the door, revealing a sun bright lit area, a grassy plain, and at the distance, a walled city. As the walk out of the tunnel, Thalia and Piper stared at the city in shock while Leo whistled, but was also as shocked as them.

Naruto grinned at them. "Ladies, and Elfie, welcome to the second demigod camp and the home of the Romans. Camp Jupiter."

"Definitely bigger than Camp Half-Blood." Thalia commented as the four walk over to the bridge. As they walk on the bridge, Thalia, Piper, and Leo noticed a statue of a man with no arms.

"You are not welcome here, Greeks!" The statue stated in a baritone form. Then his eyes locked onto Naruto and his eyes widen. "Naruto? What are you doing here?"

"...The statue just spoke." Leo said in disbelief. This world is just getting weirder and weirder as time passes. Piper look equally shocked while Thalia looked surprised, but not overly so.

Naruto ignored them. "I want to discuss something with the praetors Terminus. Something that threaten the safety of the demigods, both Greek and Roman."

"What are you talking about?" The statue, now known as Terminus, asked before his eyes narrows at the distance. "What threatens Camp Jupiter."

"My people is what threatening them." Naruto told him seriously. "Several of them have been coming after me for months now. And they've been trying to kidnap demigods in order to blackmail me. In fact, there are several in this vicinity right now."

"Wait, what?" Thalia said in alarm, turning around and looking for anyone else here. "How long did you know that Whiskers?"

"Halfway through the tunnels." Naruto replied easily as look intently at Terminus. "I'm guessing that you didn't notice them, considering you would've stopped them from entering the border." 'Guess they can still use slight genjutsu as long as it doesn't Mr. D's territory.' Naruto thought with a groan.

"What are you talking about?" Terminus demanded. Naruto sighed before encasing his hands with chakra and then snapping his finger in front of the statue's head. After that, Terminus' eyes widened once more. "T-That's impossible. How did they pass the border without me noticing?!"

"We're that good." Naruto retorted walking in front of Thalia, Leo, and Piper. "You guys are persistent, I'll give you that. And it look you stopped underestimating me, since I sensed at least thirteen of you here."

(With the Leaf)

"Shit." Kiba cursed under his breath. "There goes the element of surprise."

"And it also takes the enemy element of surprise." Kurenai told them. She turned to them. "If possible, we'll try to form a temporary alliance with the shinobi to take down Naruto." Some frowned, but nodded to this.

(With the Rock and Cloud)

"Damn." Kurotsuchi cursed under her breath. "It look like we can't surprise attack all of them."

"Remember your roles everyone." Samui told the group. "Also, we'll try to form a temporary alliance with the leaf ninjas." All of them nodded before moving to the leaf's position.

(With Naruto)

Naruto waited a few moments before turning to Terminus. "I gather the Roman army if I were you. While I'm confident in my ability, I don't think we can face thirteen well trained assassins."

Terminus frown. "Four Greeks defending our home! It's something I would never imagine happening!" Then he sighed. "Yet, you achieve the impossible more than once."

"It's a habit I picked up." Naruto responded back before taking out Kasai. "Thalia, Leo, Piper, get ready for a fight." The three nodded before they took out their own weapons.

"Fighting against fifteen trained assassins?" Leo rhetorically asked, readying his hammer. "I'm not sure if I should be excited or scared."

"Excited/Scared." Thalia and Piper said respectively, with Thalia holding her spear and shield eagerly while Piper held her chain nervously.

As they said that, Terminus began speaking in Latin, which Naruto heard, "At arms! Enemies at the Gate!" Just as he said it, an alarm sounded.

Naruto then perform the shadow clone jutsu, forming two clones. "Go get the romans." Naruto ordered the clones. The two nodded before teleporting in a flash.

Just as the two clones teleported away, the group of ninjas revealed themselves. Naruto's eyebrows rose in surprise. "Well, I never thought I see this happening. The Cloud and Rock working with the leaf."

"A temporary alliance." Kurenai told him. She, Anko, Hana, Yugao, Hinata, Kiba, and Shino, along with the four Inuzuka hounds, are here. With them, are three Cloud shinobi and three Rock shinobi. "As long as they don't kill you or harm you badly, we will work together for now."

Naruto sigh, turning his Kasai into a naginata. "Will you just give up?" Naruto stated, looking at his friends and surrogated mother. "I'm not coming back. I've shown that for months with all the bodies and injured shinobi."

Kurotsuchi snorted. "Man, you Leaf really are weak." Anko, Kiba, and Hana glared at the Tsuchikage's granddaughter for that insult.

"Yeah, well we were holding back last time!" Kiba snarled, growing his claws. "This time, we're forcing to come back even if we have to force you Naruto! And I doubt your team can help you, seeing as I beat one of them!"

Thalia's eyes twitched. "You got lucky Kibble breath." Thalia growled, readying her spear. "This time, I will fry you until you're a grilled dog."

Naruto look at the situation. There are thirteen shinobi, seventeen if you count the dogs, and most seemed to be skilled. He'll need to eliminate some of them quickly in order for them to get an advantage. Maybe….

Naruto grinned and then grabbed two kunai. "Catch!" Naruto shouted, throwing the kunai at the group of Rock and Cloud shinobi. All of them dodge the kunai easily, making Naruto smirk. Too easy.

Just as the group stopped moving, two Narutos suddenly appeared behind two of the Rock shinobi with one Rasengan each in their hands. 'Hiraishin!' The Cloud and Rock thought in shock. And a Rasengan to boot.

"Rasengan!" Before any of the two Rock shinobi could move, the clone and original twisted the spheres into their abdomen, sending them sliding across the grassy ground.

"Crap." Hana said under her breath before looking at the demigods, who are running towards them with weapon ready. "Kiba!"

"Let's do it!" Kiba and Hana, along with their hounds, run towards the demigods before jumping and each of them forming a fang over fang. But they weren't done. As they got closer to the teens, all of them merge with one another and form a giant Tunneling Fang.

The demigods stopped with wide eyes as the technique came towards them. "Ninja Art: Tunneling Fang!" Kiba and Hana said at the same time.

Naruto's eyes widened and was about to teleport to them when he saw Samui, Omoi, and Karui swing their swords at him. Knowing he didn't have the time to activate his seals, he was forced to block all three attacks. "Thalia, Piper, Leo, move!" Naruto shouted to them as he put his focus on the current enemies.

The three was about to do so, or at least attempt, when they heard something above them. "Wind style: Great Breakthrough!" Before anyone knew it, Kiba, Hana, and the hounds were pushed back by a very powerful gust of wind, causing them to lose control of their technique and send them tumbling onto the ground.

Kiba groaned as he slowly pushed himself up. "What the heck….?" Kiba groaned, holding his side. That was a very powerful Great Breakthrough.

Naruto grinned before pushing back the three Cloud shinobi and jumping away from the group of shinobi, and closer to his team. "Made it just in time Fly Boy."

A young man, who's probably the Fly Boy, jumped beside Naruto. The teen is blonde, with sky blue eyes and white skin. He's wearing golden armor, along with a purple cape attached to his shoulder and neck. And he's currently giving Naruto a dry look. "Why do you come here with new enemies half the time?"

"Most of it is for training Jason." Naruto responded, forming another Rasengan. "The rest is just shitty luck." The goddess of luck and goddess of revenge sure love to mess with his life, that's for sure. He didn't notice Thalia's eyes widen when she heard the name. Is it her Jason….

"And you're luck is about to get shittier!" Yelled Karui, with her, Samui, and Omoi charging at them with their swords. The two blondes tensed, ready to fight them off, when they heard a shout

"Ninja Art: Shadow Spear Jutsu!" Team Samui's eyes widen when they saw several spears come at them and then they had to jump back to avoid all of them.

Naruto grinned as another person jumped at the two blondes' sides. "Rey-chan, glad you could make it." Naruto responded happily. The person dubbed 'Rey-chan' is a girl Piper's age with long black hair braided into a long ponytail, and is wearing the same armor Jason is. "I assume you got a quarter of the Legion here?"

"We did Naruto." Reyna responded, as Thalia, Leo, and Piper join up at their side. "I assume that these Greeks are on our side?"

Naruto nodded while the Greek demigods felt a bit guarded. "Try to be civil with them. We have shinobi to fight." Reyna nodded and focus on the enemy while the legion gathered behind their Praetors and the Greek demigods.

The shinobi gathered up around each other as well. "We'll give you one more chance Naruto." Kurenai told him, pulling out kunai. "Please surrender now. If we don't….we won't be help responsible for what happens."

Hinata and Anko look at each other, neither of them wanting to do this. Its obvious Naruto won't just abandon these kids, even for them. So this isn't going to end well.

Their thoughts were correct when Naruto shook his head. "I would offer the same thing, but I know you won't accept it." Naruto then turn to his team and the Romans. "If you want to win this fight, you must aim to kill." Naruto called out to everyone. "These aren't monsters with little intelligence. They are strong shinobi, capable of fighting a regular army, so don't hold back."

"Yes sir!" The Legionnaires stated, holding their shields and keeping their swords above it. They waited for just a moment before Team Samui ran at them, all of them with swords at the ready. Reyna called out this time. "Romans, deploy defense!"

Six of the romans jump in front of Team Samui just as they got close to the demigods, blocking their sword swings. "Vulcan's flame!" Reyna called out.

Before Team Samui had any time to react, three of the legions jump and perform rapid hand movements. "Fire style: Fireball jutsu!" Their eyes widen when they saw flames shoot out of their palms, and they force to push back.

"Dakota, now!" Jason shouted, and a black haired boy jump over the legionnaires before running up to the Cloud ninjas. They tried to attack him, but the boy kept dodging their attacks before grabbing Karui's wrist and use her sword to block Omoi's own sword. He then threw them on the ground with a strong push and dodged a downward slash from Samui before doing a roundhouse kick, sending her to the ground.

Kurotsuchi used that to run pass Dakota, and then jump over the defense line. "Reyna, Jason?"

"Got it." The two said before Reyna ran at Kurotsuchi. Reyna and Kurotsuchi clash sword with one another, sparks being formed.

The Rock shinobi grin cockily at Reyna. "I suggest you surrender before I put you down little girl." Reyna growled at the insult given to her.

"We do not surrender." Reyna stated before they push each other back. They then fought one another, blocking and dodging each other's attacks before Reyna push both swords upward. "Jason, now!"

The blonde suddenly burst forward almost like lightning and punch Kurotsuchi in the gut before sending himself and the Rock ninja girl flying. Literally.

"...He can fly?" Leo said in disbelief.

"He can fly." Naruto said with a grin.

Jason sent himself and Kurotsuchi high above the ground, but not high enough where no one can see them. Wasting no time, Jason threw her and then started summoning a thunderstorm. As the girl got closer to the ground, Jason shot down a bolt of lightning right at her. An explosion came right as the girl got close to the ground.

"Wow." Piper said in awe. Leo nodded in agreement to that while Thalia was too stunned to talk.

'I-Is that you really Jason?' Thalia thought in her head. Tears threatening to rise up in her eyes.

When the smoke cleared, a giant white snake with burns on it (Most likely from the lightning) appeared instead of an unconscious Rock village kunoichi. The snake then disappeared, revealing Kurotsuchi, who looks completely unharmed.

Kurotsuchi glared at the leaf. "I didn't need help you know."

"Says the girl who was falling several meters from ground, with a lightning bolt coming at you." Anko retorted. Kurotsuchi scoff and look away, mainly because she couldn't think of anything else to say.

Reyna gritted her teeth. "The attack should've put her unconscious."

"But it didn't, due to Anko's summoning." Naruto stated as he gazed at the shinobi. His eyes widen when he didn't see the Inuzuka sibling or their hounds. "Everyone scatter!"

No one questioned his command and started moving to scatter, when a cyclone like attack burst from the ground, sending some of them stumbling, but they manage to scatter.

As Naruto moved, he noticed in the corner of his eyes that an army of bug are quickly moving around their position. 'Tunneling Fangs above us while several of Shino's bugs will come towards rapidly.' Naruto thought in his head. 'Clever, but not something I can't counter.'

"Leo, fire bullets!" Naruto called out and the elf boy grinned before perform rapid hand movements and started breathing in. "Fire Style: Fire bullets!" With that, the two of them started shooting out fire bullets. "Jason, get a windstorm coming!"

Jason nodded before performing rapid hand movements up in the air. "Wind style: Great Breakthrough!" With that, a very strong gust of wind came all over the field, causing Kiba, Hana, and their hounds to be blown away, no longer maintaining their jutsu, while the wind expanded the fire bullets, causing all the bugs to be obliterated.

Shino sighed. "We're at a disadvantage here." Shino stated. "Five of us are already down, and we can only use a bare minimum of ninjutsu and genjutsu. Regular taijutsu or kenjutsu will not stop them either, and they can counter our every move."

"Only because of the former jinchuuriki." Kurotsuchi responded back, narrowing her eyes at Naruto. "And how do you kill a serpent? By cutting off the head." With that, Kurotsuchi charge at Naruto.

Naruto saw the Rock ninja come at him, and use the blade of his naginata to block her sword. As he pushed it down, Kurotsuchi performed a roundhouse kick, which Naruto dodge before pushing her back. Then he sent out several stabs at her, all of which she blocked, before swing her sword right at his lock, causing him to jump up. She use that opening to perform another roundhouse kick, something that Naruto blocked with the blunt end of the naginata, but ended up pushed to the side. He used the momentum to backflip and land on his feet.

Naruto didn't bother with handsigns this time. He made a flaming ball of fire before throwing it at Kurotsuchi. The girl's eyes widen and then jump up, dodging the attack.

But leaving herself a target for one Jason Grace.

As fast as a bullet, Jason came at Kurotsuchi, and before she knew what was happening, he gave her a wind powered punch to the face, causing her to crash into the ground.

Naruto grin at his fellow blonde and nodded to him. "Thanks Fly boy." Naruto said, to which the boy nodded back at him. Then he turned to the remaining Shinobi. "We still got seven more to go. It's not over yet."

"It is for you Uzumaki!" Naruto heard Kiba roar and he look back to see a big ball of smoke. All of them look at the smoke, though some Romans kept their eyes on the other shinobi, when a giant two-headed dog emerge from it.

It growled at them all while some of the demigods cried out in shock. "The Cerberus!" One of them said in disbelief. Naruto shook his head.

"No. Just a trick Kiba made." Naruto told them all just as the giant dog started running towards him. The legionnaires got out of the way of the dog, knowing that they couldn't stop it, as it ran at Naruto. Naruto close his eyes, his muscles starting to bulge and his veins started popping. As the combined Kiba and Akamaru got close enough to bit Naruto's head off, the blonde through a punch at him.

Time seemed to slow as a crack in the air formed. Then, just like that, it returned to normal with the giant dog went sent back to the other side like a train ran over it. It crashed in the ground, creating a giant hole. The jutsu then broke, showing a very injured Kiba and an equally injured Akamaru.

Everyone was silent after that. "Well," Jason spoke up. "That's kne. When did you learn that?"

"During winter." Naruto responded, breathing a bit heavier. This is taking a bit of energy out of him. "I'll tell you the story later. Right now, let's focus on the other shinobi."

Jason nodded and just as he look back, four tunneling fangs suddenly came at the group of demigods. Naruto's eyes widen before looking back, seeing Hinata and Shino running at them.

"Thalia, lightning!" Naruto commanded. Thalia immediately gathered lightning into her hands before thrusting it out and electrocuting Hana and her hounds, and sending them crashing into the ground once again.

When Shino got close, he summoned his bugs and sent them at them. Naruto, knowing that he none of them will be able to dodge, heated up his body and sent a heat wave hot enough to burn the bugs.

Hinata saw three romans coming at her and beat them down with her Hyuuga Style ninjutsu. She rushed towards Jason, since he was the closest and was one of the bigger threats.

Jason brought his sword up to defense, but it was useless, as Hinata swat it out of his hands no problem. Before he had time to react, she perform several perform strikes to the arms, legs, and body, before sending him sliding to the ground with a strike to the chest.

Thalia's eyes widen at the scene before narrowing her eyes at the brunette. She charged at her, ready to stab her with her spear, but Hinata saw it coming. The heiress ducked under a stab before doing a sweep kick, sending the daughter of Zeus crashing into the ground. When she saw Jason slowly getting up, she ran towards him, ready to immobilize him with more strikes to the arms and legs.

But before she had the chance, she was suddenly hit in the head by a chain, sending her backwards and stumbling into the ground. Jason look at the scene, a bit stunned, before looking to who saved him. Turns out, it was one of the Greek demigods that Naruto came here with.

Jason smile at her and nodded to her as he got up. "Thanks for the help." Jason told her gratefully.

She smiled back. "It seemed like you needed it." Jason was about to say something else when he noticed something behind her.

"Get down!" Piper spin around to see the three ninja hounds above her. Her eyes' widened, but before they could attack, Jason got in front of Piper and threw out a powerful gust of wind, throwing the hounds away from her. The three slowly stood up, wanting to fight more, but then collapsed.

Jason sighed in relief before turning to Piper, who look at him with astonishment and gratitude. "You're alright?" The girl nodded, casting her eyes down with a small blush. "Guess we're even then."

"Guess so."

Meanwhile, Naruto was fighting Shino with his naginata while the bug user is fighting the fire user with his bug sword. The two traded blows before Naruto, the more experienced weapon user, disarmed Shino and then cut him down, only to reveal that it was the bug user's clone.

"You really shouldn't underestimate me Naruto." Shino called out from his position before sending several bugs at Jason, Piper, and Thalia. He knows that Naruto will burn his bugs, so he targeted his teammates in hopes of evening the odds.

But that didn't come to be as several fire bullets eliminated bugs. Those came from Leo Valdez, who was grinning at Jason, Piper, and Thalia. "Does that mean you all owe me something?"

"Not a chance Valdez." Thalia and Piper deadpanned while Jason chuckled a little.

Shino frown, but before he could try something else, he heard a whisper in his ear. "I didn't." Shino's eyes widen behind his glasses, and just as he turned around, he got kicked in the side by Naruto, sending him skidding into the ground.

Naruto huff a little, feeling his chakra drain more and more. It's not the point that he needs to rest, but it still more than he usually uses. He gaze went to Hinata, who is slowly getting up. Naruto's eyes soften at seeing the first friend he'd ever gotten in the Leaf.

"Reyna." Naruto called out to her. The girl looked towards him. "Help me knock down Hinata quickly." Reyna nodded before the two ran at Hinata.

The Hyuuga noticed the two and attempt to get into her stance to defend herself, but Naruto and Reyna knocked her down with two roundhouse kicks to the stomach. With that, the young heiress slid onto the ground.

The roman demigods, their praetors, and his own team gathered as Yugao, Kurenai, and Anko slowly walk towards them all. "Stay here." Naruto commanded all of them. "I'll take care of this."

Naruto walked out of the group of demigods and towards the three women. They were the last one he need to face. One of them is his protector and the other his mother figure. Kurenai may not be in either of those categories, but she's still one of Naruto's precious.

It hurt to face them all. It always hurt to face his friends. He's just good at hiding it.

Naruto gaze at all three of them. They gazed back. "So you really not coming back, huh?" Anko asked, though it was more of a statement than a question. "Nothing will change your mind huh?"

Naruto shook his head. "The Leaf Village isn't my home. It never was." Naruto said, his gaze set on his mother figure. "I love you Anko-kaa-san, I really do, but I can't just abandon my friends and family here."

Yugao and Kurenai's were filled with sadness. "Then we got no choice Naruto." Kurenai said as she and Yugao pulled out their own swords. Since the genjutsu mistress couldn't access any of her strong genjutsus, she was trained by Yugao to use the sword.

Wanting to end this quickly, Naruto perform a series of hand signs before making four clones. "Jump!" Naruto stated before they all jumped. When they got high enough, the five Naruto launched at the group of women like bullets. As they got closer, they started turning bright red, making their eyes widen. Clone bombs.

"We need to move!" Kurenai said to them. When she and Yugao tried to run, something latched onto their legs and fell on their stomachs. Their eyes widen when they saw that it was snakes, and look behind them to see Anko far from them, with an apologetic expression.

"Clone bombing!" The Narutos yelled before hit their target, causing all four of them to explode. In the midst of the explosion, Yugao and Kurenai were thrown, the both of them having several burns and unconscious while Naruto jump out of the explosion, unharmed. But very tired.

Naruto look as his surrogate mother in surprise. She smirked at his shock look. "Don't give me that look sochi." Anko said, walking over to him. "I have always held you above the village needs. And I've been thinking of joining your camp of yours; teach the other gaki a thing or two about fighting."

Naruto stunned slowly slipped away before he formed a smile. With no hesitation, he ran up to Anko and gave her a tight hug. "Thank you mom." Naruto whispered, slight tears in his eyes.

She smile and hug him back, glad to be with him once more. And this time, it's permanent.

Piper, Thalia, Jason, and Reyna smiled softly at the scene in front of them while Leo look down, memories of his own mother coming to his head. He's glad that Naruto has a mother figure, but he still envied his half-brother.

The two walk over to the group of demigods still near the bridge of the camp. Naruto was about to order the demigods to get all the shinobi around the hill when something caught the corner of his eye.

Somehow, Kiba and Akamaru (Transformed as Kiba) manage to get behind Piper, with a kunai in their hand. Many of the demigods now noticed, but before any of them could yell a warning, Kiba beat them to it. "You're mine!"

"No!"

The sound of a blade ripping flesh came into everyone's ears. But it wasn't Piper who was hurt. It was Kiba and his hound.

Naruto manage to use hiraishin just in time to get in front of Kiba and Akamaru, and save Piper. But in order to stop them from killing him and Piper, he turned his Kasai into his signature axe and sank both ends of the blade into their chests.

The two looked at Naruto in shock. The boy looked at them both in equal shock. All around, the demigods and shinobi were looking at the two. Hana, Hinata, and Shino were the most shocked out of everyone.

Naruto continue staring at the dying Inuzuka's eyes before looking away. "I'm sorry." Naruto said softly, his voice slightly cracking, before he pulled out the axe from their chests. The two slowly fell onto the ground as they gave their last breath.

And that's the end. So, for all those who called for a death of a shinobi? Well, here's your wish. I was debating doing this or just keep every shinobi alive, just to spite the flamers/complainers, but thought this will be good for Naruto's character development. But be warned, Naruto isn't just gonna be walking from that like it never happened.

Next up, we'll see how Annabeth's group is doing. I hope everyone liked this long chapter. Review, favorite, and follow and I will see you later.
