Digi does not own Naruto, but that little brat is going to be the reason I finally put my back out for good; no good Leaf-nin are going to be the death of me.

Matsumoto stared at Naruto in horror before his gaze drifted back to the creature, still collapsed over on the other end of the room, a crater in the wall marking where it impacted. Naruto was about to walk forward and finish the creature when Matsumoto ran out in front of him, arms spread out wide as if blocking the blonde's way.
"What are you doing Matsumoto?! Didn't you see what that thing did to those scientists! We need to do something before it's too late!" The greying man just shook his head firmly, his knees shaking slightly from seeing his co-workers die as well as the power Naruto had displayed.
"Y-You can't!" Some steel seemed to return to the man's eyes as he straightened up, his stance growing more rigid. Even so, Naruto could tell that while he may have received enough training in Chakra to summon, the man had no experience in Taijutsu. "It's my life's work! Everything I've ever done has been for this! If you destroy it my life will have been a waste! We need to simply contain it, not kill it!" Behind him the maggot-esque creature stirred, almost languidly getting back up using its many tentacles as supports.
"Move aside Matsumoto! Now!" The man stood firm though, even as the creature looked around, its insectoid compound eyes focusing on the balding man. Naruto made to use his shakujou to incapacitate the scientist for now, only to realise it wasn't in his hand. With some shock he realised that it must still be in Honoka's room, he never took it with him. In his moment of hesitation one of the creature's tentacles lashed forward, intent on snaring Matsumoto, no doubt so he could join his co-workers.
"Banshou Ten'in." Just before it could snag the man he was pulled forward by some invisible force, the tentacle closing on nothing but air. Naruto quickly caught the man, pushing him to one side before they could both be crushed as yet another tendril slammed down where they had been moments before. The creature let out a loud and high-pitched shriek at its targets getting away, its large eyes glaring intently at the blonde.
"Shinra Tensei!" Naruto raised both hands this time, wanting to make sure the creature didn't get back up from this hit. However even as the invisible wave of gravitational forces slammed into the beast its eyes briefly began to glow an ominous red. Naruto could only blink in surprise when the creature didn't even budge from its position; he watched as the Chakra was merely absorbed by the beast instead of impacting with it like it should have.
"Well that's not good." He dived out of the way again as another of the creatures tentacles tried to crush him mercilessly. He rolled to the side, near where Matsumoto was now propping himself up against a desk, panting heavily.
"T-That won't work, the creature was designed to absorb Chakra from Ninjutsu." Naruto glared at the man, grimacing to himself; that was a lot like his Preta path and would certainly make things difficult, especially without his shakujou.
"Is there anything else you can tell me about it that will allow me to defeat it?" The greying man just looked up at him hopelessly, obviously having an internal struggle on whether or not to help Naruto. On one hand the chances of them making it out of here alive were growing increasingly slim. On the other hand he couldn't bear to see his life's work be destroyed only minutes after he had finished it.
"You can't destroy it! Please!" By now the man just sounded desperate making Naruto turn away in disgust; he couldn't stand that this man would allow innocent people to die just to save an experiment. Unfortunately any more thoughts were interrupted by Naruto having to jump out of the way of another attack.
"Damn, I need to do something about those tentacles." He sprinted across the room, ducking and weaved between various grey tendrils the creature kept sending after him, obviously identifying him as the main threat. However before Naruto could come up with a plan he saw a green blur race past. A moment later the creature let out a deafening shriek as one of its many tentacles suddenly fell from its body, green liquid spurting from the wound.
"Need help?" Fuu landed next to him a second later, two long swords made of water held in each hand as she glared at the creature. Naruto merely smiled at her as he began to think about what he could do.
"If I can hold it still, do you think you could deal with the tentacles?" Fuu narrowed her eyes at the creature, which was now staring at her intently with murderous blood-red eyes. She nodded once, settling into her stance as she avoided a barrage of crushing attacks from the beast, slicing away at its flesh when she could. Naruto just watched her before nodding and channelling his Chakra quickly, hoping to deal with the creature's many limbs all at once.
"Kuchiyose!" When the smoke cleared the creature looked around, staring at the new arrival with... hunger? Naruto ignored that as he jumped up atop the enormous octopus he had summoned, the Rinnegan eyes it had telling him it was not a real summon. From the corner of the room Matsumoto stared up at the enormous invertebrate with awe, he had never heard of an octopus contract. "Get ready Fuu!" Without so much as a word the octopus moved forward with surprising speed for a creature so far out of its element.
A moment later the beast suddenly found all its tentacles ensnared by the limbs of Naruto's octopus, the suction cups keeping a very tight grip. Knowing that was her signal Fuu dashed forward, nothing more than a blur to most in the room. In seconds it appeared to be over, Fuu skidded to a stop, her water-cutting swords falling uselessly to the ground as the Jutsu ended. When he looked back there was a moment of pause before the creature once more let out a terrible shriek of pain. As one, all its tentacles slid off of its body, the limbs spurting green blood up into the air as they thrashed about.
However before anybody could capitalise on the creature's sudden disadvantage a new tentacle that had been hidden behind its body suddenly whipped out, faster than the others. In only mere moments it had wrapped around the body of the octopus and slowly began to reel the giant cephalopod towards it. Naruto had to jump back as his summon was immediately absorbed into the beast, as if it had never been there in the first place.
"I told you, nothing will work against it." Naruto had landed near to where Matsumoto was cowering behind a desk on the far side of the lab from the creature. "It has the ability to absorb other summons to expand its abilities and grow stronger." Naruto simply stared at the man in a mixture of frustration and disbelief; he wondered what had possessed him to make a creature this difficult to control.
"Naruto!" The blonde swivelled on one foot to see an enormous tentacle, thicker than the ones before, about to slam down on his body. Thinking on the fly he suddenly blasted away into the air, one arm looped around the doctor's waist, as he used a quick Shinra Tensei to get him a way. Milliseconds later the clean white tiles were smashed into shards as the thick limb crashed down on the floor, leaving a long and deep imprint.
When the blonde looked at the beast it had re-grown all of its tentacles, except they were longer and thicker now, each having a single row of suction cups running their length. He set Matsumoto down on one of the higher catwalks, hoping the man would be safe here, although the chances were looking increasingly grim. Ninjutsu and his techniques using Chakra were useless, his summons only made the beast stronger and if he got close enough to use Taijutsu he would most likely get absorbed. He had no intention of finding out which of their abilities to absorb Chakra was stronger.
"Dammit! How do I beat this thing?!" He looked to Matsumoto again but the man was no use, he was just staring down at the maggot-like beast with wide eyes, shivering occasionally. Before he could think of anything though his eyes widened in surprise; below them Honoka had run forward, already flashing through a long chain of hand seals. When she got close enough she crouched down, slamming her hands onto the floor as an enormous sealing matrix spread out.
"Honoka! What are you doing!?" The girl just ignored Naruto as the long lengths of ink-black sealing symbols began to peel off of the floor, shooting out like chains. The beast struggled beneath the bright lines of light but slowly began to be pushed to the floor. However its eyes once again flashed that ominous red; the change was obvious as Honoka grunted from the exertion, sweat beginning to gather on her brow.
"Please! Do something quickly! I can't hold it for very long!" The redhead's cry broke him from his surprised stupor as he vaulted the catwalk, dashing across the ground as a long black Chakra rod slid from his sleeve. He wasn't sure if this would work but he didn't want to give up an opportunity like this. Apparently Fuu had shared his thoughts as she too sprinted towards the beast, water-cutting blades once again extended from her hands. They moved past one another before moving towards their targets, Fuu jumping up into the air.
Naruto ran to the nearest tentacle, slamming his Chakra rod down into the tip, driving both it and the limb into the floor. As soon as he did he rolled over the tendril, another Chakra rod already slipping from his other sleeve. As soon as he reached the next one how repeated the process, driving the sturdy rods straight into the beast's flesh and ignoring its pained cries. As a monk he hated seeing any creature, even one created for the sole purpose of killing, hurt in any way; however he would never allow this thing to escape un-controlled.
"Takigakure-ryuu: Kakuchou!" As Fuu descended from her jump the two swords in her hands suddenly grew outwards, extending past their previous limits. With a cry the mint-haired girl brought them down, slamming both into the creatures head all the way up to her hands. She stood there on the beast's bulbous head for a moment, panting slightly as she maintained the Chakra-intensive technique for a moment longer, making sure it killed the creature. However her orange eyes suddenly widened as she felt her Chakra ebbing away, flowing out through her swords and into the beast; at the same moment she also felt her feet start to sink.
"Naruto!" The blonde looked up before he could impale the last of the tentacles, seeing Fuu slowly being absorbed into the creature. He was about to throw his hand up to draw her back but the beast used that moment to slam him with its last remaining free limb, sending him flying across the room. He twisted his body before it could impact painfully with a wall, landing feet first so he could flip back down onto the ground safely.
"Fuu no!" Naruto would have attempted to save the girl but his Banshou Ten'in wasn't that accurate from this distance. Before he could sprint over there to help her though, the same golden tendrils of light suddenly broke away from the creature, freeing it, but at the same time wrapping around just Fuu. In a few seconds she was free of the beast as Honoka drew her back, leaving the green-haired girl panting on the floor beside the redhead, her eyes widened in fear.
Naruto breathed a sigh of relief before he too opened his eyes in shock, a shadow begun to descend on the two girls as the beast brought a tentacle down in a sweeping motion to crush them both. However before it could they suddenly flew backwards, as if yanked back by invisible strings tied around their waists, both crashing into Naruto's opened arms. They lay there on the floor for a moment, Fuu and Honoka taking small breathers while Naruto was trapped due to their bodies lying on his arms.
"Uhh, Fuu? Honoka?" The two girls looked up at his face for a moment before blushing and looking away, quickly scrabbling back to their feet. Naruto got up slightly more slowly, keeping an eye on the beast as it writhed on the floor, obviously in great pain from being impaled through its tentacles and stabbed twice in the head. He was surprised the thing wasn't dead, but then again it had already proved how resilient it was; no doubt it had absorbed a lot of the Chakra from Fuu's water blades before they could do the damage intended.
"How do we get rid of this thing?" Even as the blonde watched the beast began using its one free tentacle to slowly draw out each Chakra rod from its limbs, shrieking in pain with each one it removed from its flesh. Suddenly they all saw Matsumoto appear from the catwalks, walking slowly towards the beast, Honoka's eyes widening in horror.
"Matsumoto-sensei! What are you doing!?" The older man ignored her though, slowly walking towards the beast with his arms opened wide. The creature kept one eye on the man, it's free tentacles swaying slowly as it continued to remove the rods from the rest.
"Yes! That's right! You recognise me don't you? It's me, your creator, your father!" The beast continued to gaze at the man, unmoving for the moment as Naruto, Fuu, Honoka, and Shizuku could only watch on, wondering what would happen. "Listen to me! You should stand down and return to your tank, that's an order!" The beast's head cocked to the side slowly before its gaze drifted across to the metal tank in the centre of the room. "That's right, listen to my orders as your creator!" Slowly the beast limbs rose into the air, as if in compliance, eliciting a large grin from the aging scientist.
"Yes, that's ri-gah!" Everybody's eyes widened as Matsumoto suddenly doubled over, spitting up blood from his mouth as he looked down with a shaky head. Protruding from his stomach was a long grey tentacle with a sharpened tip, stained red from the man's blood. He grasped it between his shivering hands before looking up at the creature, his eyes widened in shock that never left his face as he slumped over. Before anybody else could react his limp body was raised into the air before swiftly being absorbed into the creature.
"No! Matsumoto-sensei!" Honoka was the first to break out of the shocked silence that had enveloped the room, running forward only to be grabbed from behind by Naruto and pulled back. Just in time too as not a second later one of the tentacles slammed down in front of them, crushing the tiles in the spot Honoka was just in. "No! Let me go! Matsumoto-sensei!" She struggled against the blonde's firm grip, unable to break away as Naruto suddenly jumped back again, avoiding another attack aimed at the two of them.
"Honoka stop it!" He landed back down on one of the upper catwalks, closer to the entrance of the facility, holding Honoka back as she struggled against his grip.
"Let me go Naruto! I have to stop it!" Naruto just kept holding her down, passively using his Preta path to weaken her slightly until she stopped struggling. Below them the creature thrashed about, obviously displeased it had lost its target. In the meantime Fuu had recovered, dashing back in with her water blades in order to severe the beast's tentacles again.
"Honoka stop, there's nothing you can do, it will just absorb your seals!" Finally the red-haired girl dropped resisting, falling slack in Naruto's arms as she quietly sobbed.
"B-But I have to keep fighting. What about Matsumoto-sensei?" She sobbed again, louder this time as she latched onto one of Naruto's arms, pressing it against her chest as tears trickled down her cheeks. Naruto just patted her on the back, knowing what the loss of a loved-one felt like as he did his best to comfort her and keep an eye on the creature.
"You don't have to fight anymore Honoka, leave it to us." Suddenly the girl bit back her tears, standing up before Naruto could grab her.
"No! I can't just sit here while that thing runs loose. I need to fight because it's what I believe is right!" Before Naruto could stop her she dived over the edge of the catwalk, rolling to her feet when she hit the floor. She immediately crouched down, speeding through hand seals as fast as she dared, different ones this time. When she slammed her hands down that time another sealing matrix spread out, however when the symbols peeled from the floor they were a deep red, almost as if they were set aflame.
As Fuu darted and weaved between the various tentacles, slicing and cutting any exposed flesh she could while keeping out of the beast's reach, Honoka's seals rushed forward. However instead of suppressing the beast like before, the new seals seemingly seared straight into the creatures flesh, leaving deep black marks on its skin. Like before the beast shrieked in pain, glaring at the two girls as its eyes glowed red in anger as it thrashed about. However like before it eventually became too much, the creature just had too many limbs and in the end it simply forced them back or threatened to crush them.
Fuu panted from her position, the water-blade in her hand finally bursting back into its harmless element. She suddenly straightened up, her fists clenched in anger as an oppressive aura suddenly spread out across the room. Everybody looked to the girl as virulent red Chakra gradually spread across her body like a cloak, two crisp, insectoid wings rising from her lower back out of the corrosive shroud. Faster than most could see she darted forward, fist cocked back as she approached the beast.
She ducked underneath one of its tentacles, intent on swatting her away like a fly; although flew past it would be more accurate. Her vibrant Chakra wings beat incredibly quickly, creating a slightly hum as she skimmed across the floor. Finally she reached the beast, slamming her fist right into one of its eyes with a sickening squelch. Time seemed to slow a little as he fist sunk into the creature's vulnerable eye, the beast crying out in agonising pain, raising a tentacle to strike her. However Fuu moved out of the way, allowing the beast to slam itself over the head with its own limb.
However in its anger it lashed out with all of its tentacles at once; now furiously mad at the floating Fuu. The girl was fast, but not enough to avoid all of the tendrils at once; one long tentacle wrapped around her body at the waist, squeezing her tightly. She tried to smash her fist into it, hoping to get the beast to let her go but it had the opposite effect, crushing her even tighter as it coiled. She grunted in pain as she felt her bones begin to creak, her features twisting into a grimace.
Suddenly she gasped as the corrosive Chakra around her body slowly began to ebb away, sinking into the beast's tentacle as its remaining eye glowed. As the vile but protective shroud began to dissipate the beast squeezed even harder, slowly drawing the girl towards its body. However before it could begin to absorb her everybody suddenly saw a streak of black fly across the room. With another sickening cry the creature dropped Fuu roughly to the ground, its tentacle waving madly in the air allowing everybody to see the long black rod impaled all the way through.
"Banshou Ten'in." A moment later and Fuu was safely in Naruto's arms, being gently laid on the floor to one side. They had a brief moment of respite as the beast thrashed about, mourning the loss of its eye and trying to lessen the pain in its limbs that were healing at an astonishing rate, no doubt thank to the enormous amount of Chakra it absorbed from Fuu. Naruto just frowned, struggling to come up with a way of defeating a creature that could shrug off most attacks.
"Dammit, Chakra-based attacks don't work, we can't get close to it, Bijuu Chakra is useless and anything I summon just..." Suddenly an idea struck Naruto, his eyes widening in surprise at not thinking of it sooner. He suddenly turned around, dashing away from the creature and towards the exit of the facility. However before he could get far Fuu grabbed his hand, halting him for a moment as she looked up to him.
"What are you doing?" Naruto just gave her a small smile, surprising the girl given the serious situation they were in.
"It's a summoning animal right?" Fuu just nodded in confusion as Naruto grinned and sped off again, sprinting as fast as he could towards the exit of the facility. He raced past Shizuku and Honoka, the two girls giving him matching looks of confusion that he ignored. Finally he reached the outside, skidding to a stop at the edge of the ledge that dropped down into the boiling lake of lava beneath them. The blonde stopped, turning back to look into the lab where he could see the murderous red eyes of the beast staring straight back at him; he merely answered with a grim smile.
"Kuchiyose!" He slammed his hand down into the ground, right at the edge of the cliff so that the sealing matrix actually spread out into thin air. He leapt back as the area erupted in a cloud of smoke, only to clear and reveal the beast itself. Its red compound eyes widened slightly as it suddenly found itself outside, balanced precariously over the ledge. It tried to slam one of its tentacles down on the ground as an anchor but Naruto saw what it was doing.
"Oh no you don't!" The blonde leapt forward, stabbing a Chakra rod straight into the tentacle before it could get a proper grip. The creature shrieked in pan as it let go, its remaining eye widening as it suddenly fell backwards, unable to balance any longer. Naruto didn't walk forward to look down, he didn't want to see what was happening. The horrifying cries of pain and anguish were bad enough to listen to as the beast slowly melted to death in the molten rock. He nearly jumped when he felt a hand on his shoulder; he looked around to see Honoka staring towards the ledge.
"Are you okay?" Honoka just nodded sadly, dried tears staining her face as she sniffed back more. Naruto just gave her a weak smile before patting her on the shoulder and walking past to see if Fuu and Shizuku were okay.
The four young preteens were back in Honoka's room, Naruto thankfully re-united with his shakujou. He had been surprised to find that Honoka had actually carried it with her when she found him in the forest; which led him to believe she had a surprising amount of Chakra. He briefly wondered if that was an inherent Uzumaki trait, a question Honoka couldn't answer due to her not knowing her parents.
Apparently Matsumoto had found her in an outlying village in Mizu in Kuni in an orphanage, taking an interest in her due to her name. He took care of her over time, raising her and training her in any Uzumaki techniques he could find. Naruto discovered that the Uzumaki clan were not only famous for their seals but also incredibly apt in them. Most teenage Uzumaki were able to surpass what passed for a sealing 'master' anywhere else in the elemental nations.
It made Naruto wish he had looked at seals more in depth, but at the time he was more interested in finding a way to help Sora and sealing would have taken too long to learn, and that was gambling on whether or not he was a real Uzumaki. Despite all of Honoka's insistence that she could somehow 'feel' that he was family, Naruto could never quite remove that nagging doubt at the back of his mind, something he may never be able to get over.
Now the four were discussing what would happen now the facility was shut down. They had been unable to find the two remaining scientists who had run off when the creature first started absorbing their co-workers. Honoka didn't really know any of them too well, only having proper contact with Matsumoto, but she worried for them anyway. The forest was now a dangerous place with all the summons running about without any contract holders to direct them. This point brought Naruto onto something that had been bothering the blonde for a while now.
"Honoka, you've been researching summons for a while now right?" The redhead nodded from her position sitting cross-legged on her bed. Shizuku was in a chair on the other end of the room while Naruto was leaning against the girl's desk, Shakujou safely in hand. Fuu was more content to simply lean up against the wall, quite close to the door in case they had to leave quickly; it was a remnant of her conditioning in Taki she hadn't been able to break.
"Do you have any idea why I was unable to summon Shizuku when she was being taken away by the giant eagle?" The red-haired Uzumaki blinked before looking up thoughtfully, the question interesting her due to her inherited interest with all things to do with summoning she had gained from Matsumoto.
"I'm not sure; I would have to know more about your ability." Naruto just nodded, giving the girl a rundown of what he could do and had done with his Animal path up until then. As he continued to explain the awed and fascinated look on Honoka's face only grew; at one point she rushed over to her desk and grabbed a notebook, quickly scribbling down what Naruto was saying. When he was done the girl simply stared at her notes in thought for a while, going over everything in her head.
"Well, I can only give you a hypothesis until I could get more data, but the only reason I could see would be because of Matsumoto-sensei." The girl's voice was quiet at the end as her head tilted down mournfully; Naruto thought she somehow blamed herself for her mentor and father-figure's death. However when she looked up and saw all of their confused faces she cleared her throat and wiped away the tears percolating at the edge of her vision.
"I think because Matsumoto-sensei still held a viable contract with the Eagles you were unable to summon them, and by extension anything connected to them at the time. It must mean that you are unable to summon animals with a pre-existing contract with humans." Naruto frowned at that, the logic was sound after all and it was a good explanation but there was a problem.
"But I can summon the chameleons, they're an actual summon and they've had a contract with humans before. They told me so." It was Honoka's turn to frown at the new information as she returned to her notes, skimming over them briefly.
"Are their summoners still alive?" Naruto blinked at the question before shaking his head slowly making Honoka smirk; if there was anything she enjoyed it was confirming a hypothesis like any good scientist. "When a summoner dies, something happens with the contract. Their name remains where they signed it but it fades slightly, freeing the animals from that summoner, unless they were already called upon before their death. So if the animal has no living summoner then you are able to call upon them with your ability, if they do, you cannot." Naruto just looked at the redhead, impressed by how quickly she had gone through all that.
"Matsumoto-sensei may have been able to tell you more, he was the expert after all." She looked down again, obviously saddened and barely holding back her tears. "He would have loved the chance to talk to you, you could have revealed so much about summoning." At that she finally broke down, sobbing quietly to herself on the bed with her hands bunched up into fists. She didn't even look up when Naruto walked over, placing a comforting arm around her shoulders. She simply turned into his chest and cried deeply while Naruto let her, allowing her to cry out all the grief she had bottled up.
A day later and the group were standing on a beach on the west side of the island, the sea breeze making their hair and clothes flutter about. The trio were saying their goodbyes to Honoka who was tearing up slightly; Shizuku too was saddened, in the time they had spent together the two girls had become fast friends with a lot to talk about. But in the end they had to go their separate ways, much to their mutual displeasure.
"Are you sure you don't want to come with us? There's always room for one more in the group." Honoka just gave the blonde a sad smile as she moved forward and captured him in a hug.
"Sorry, but this is something I have to do. Matsumoto-sensei always promised that one day he would take me to the ruins of Uzushio, I have to make sure that I see that promise is kept. Are you sure you don't want to come with me? You're family after all." Naruto stepped away from the hug, looking at the shorter girl with melancholy in his eyes.
"Honoka we've already talked about this. You know I-" He was cut off as the girl placed a finger against his lips, a light smile running across her features.
"No matter what you say Naruto, you're family to me. Blood does not make a family, bonds do." She giggled into her hand as she stepped back, waving to the two other girls who waved back, one with more enthusiasm than the other. Naruto thought it might actually be for the best she didn't join their group; for some reason Fuu didn't get along all that well with the red-haired Uzumaki. "So I guess I'll see you around Itoko." She gave him a beaming grin that Naruto couldn't help but return with a small smile of his own.
"Yeah, in any case I want to thank you." Honoka just blinked at that, looking up at the blonde in confusion.
"Thank me?" Naruto just nodded as his smile grew slightly; he looked away for a moment as if remembering a fond memory.
"You reminded me of something my own Sensei once taught me, something I had been ignoring until now." He looked back to the redhead, pulling her into another brief hug, this time annoying both Shizuku and Fuu; although the former was still uncertain as to why. "He told me that being a pacifist is not about avoiding all conflict, but about knowing how to choose your fights." He pulled away, leaving the Uzumaki with a slight red hue to her cheeks. "You reminded me of that, so thank you." He suddenly moved back, moulding his Chakra as he walked before slamming his hand down.
"Kuchiyose!" When the smoke cleared Honoka recognised the animal as the same strange bird she had knocked Naruto and Fuu off when they had arrived at the island.
"Wow, I don't think I'll ever get tired of seeing you do that." Naruto just grinned as he hopped up onto the bird, Fuu and Shizuku quickly following him, despite the violette's slight hesitation. As they took off, the bird's strong wings beating downwards to lift them into their air, Honoka waved the group off; however she couldn't help but call to them one more time. "What are you going to do now?!" She saw Naruto's grin as he waved to her even from that distance.
"What else, I'm going to choose a fight!" The redhead just smiled as the group slowly flew off into the distance. When they were finally out of sight she turned, scratching her head once.
"Where did they leave the boats again?"
