Okay I'm back with this story, I would have done this chapter sooner but the new chapters of Fairy tail and Seven deadly sins were giving me motivation for abilities and such that Natsu could possibly have for his end powers. Like I said a few chapters back I considered using Meliodas' wrath as E.N.D ultimate power and after seeing the results of it in the seven deadly sins manga I'm 100% certain I'll be using that but only for his ultimate power, most of the intermediate and advanced powers are still being figured out.
Instead of having Issei go berserk when he uses his longinidus breaker for the first time I'm thinking of having Natsu when he has completely lost control of his powers and the Satan's have to get involved, either that or actually going along with Issei going berserk and Natsu fighting him, let me know which you'd prefer in a review or pm me P.S. I for the life of me couldn't remember how this bit of the story went in the actual series so I just kind of filled in the bits I couldn't remember with that of my own.
Since the battle with Vali and Albion a number of weeks had passed, in which Natsu and Kuroka had been carefully planning out the nekomata's plan to kidnap her own sister so she could straighten things out and reconcile with her. However, the best plan the busty feline like woman could come up with was to strike after school had ended and teleport herself, Natsu and her sister to a secluded location in the underworld. Of course as basic and flawed a plan it was it still took time to prepare, namely the portals.
Throughout the time Natsu found himself incredibly bored, there wasn't anything he could do so he just went about the city sightseeing and finding out things. The one and only thing that got his attention and relieved the boredom much to his frustration was watching that Vali guy who he felt the need to rip the guy a new one and the red dragon emperor which turned out to be the brown haired guy in Rias' peerage duke it out.
From the start the fight was a complete uphill battle for Issei and it looked like Vali would have finished him off. Well that was if it hadn't been for what Natsu would call sheer dumb luck (something he was an expert in) when Issei had somehow managed to absorb a part of the white dragon emperor's armour temporarily granting him the ability to use abilities he learned where called boost and divide. When he asked Kuroka about this later she revealed that the abilities retrospectively double a user power and cut the power of an opponent in half using that energy to supply your own. It made Natsu think that if one could permanently possess both of those abilities it could theoretically result in a never ending supply of magic
"Okay so I draw this here"
"Move this here oh and can't forget this"
"Let's see what else" Kuroka was currently mumbling to herself as she drew and moved symbol and symbol into the ideal pattern for an interdimensional portal. Its location needed to be in an unoccupied part of the underworld where they wouldn't be bother by any of the Satan as well as somewhere that would not be found easily by Rias and her group. "That should just about do it" Kuroka declared before dusting her hands off causing Natsu to spring to life from the corner of the room.
"Alright! Now it's time for action" Natsu cheered out in childish manner while doing what Kuroka had dubbed his happy dance, which was less of a dance and more of flailing of limbs. "Wow, wow, wow; calm your shit, we still have to wait a few hours before we can put the plan into action" Kuroka said in an amused tone immediately bringing an end to the dragonslayer's good mood.
"What you have to be kidding, you mean I have to wait even longer man this sucks" Natsu pouted like a child causing Kuroka to sweat drop at her mate's childish behaviour. In her eyes patience was a virtue but it appeared as though that was a virtue Natsu wasn't graced with. "Relax would you, it's only like another two hours before the school starts to close" Kuroka revealed making a look of understanding make its way across Natsu's face, "Well I suppose that isn't too bad; so what do you want to do until then?" Natsu asked as he took in their surroundings. They weren't far from the school but they also weren't in an area that was too densely populated by humans. However, as insurance Kuroka had set up a miniscule barrier that was powerful enough to fool humans if they came across the area they occupied but not so powerful that it could easily be detected.
A smirk made its way onto Kuroka's features as she strode up to Natsu and pushed him forcefully up against a tree taking the dragonslayer by surprise. "I can think of a few things we could do" the nekomata answered in a sultry tone as she leaned in closer to the slayer before giving his cheek a lick making his face rival the colour of a certain re-quip mages hair.
"W-w-w…I-I-I…?"
Natsu spluttered out unable to form words causing Kuroka to laugh at his current state, "You know you're really cute when you're embarrassed" the nekomata teased before tapping the dragonslayer's nose and twirling around causing the bottom of her yukata to lift up and flare out a bit.
"You really are a devil" Natsu complained folding his arms across his chest causing Kuroka to giggle at his ever growing childishness, "Bingo" the nekomata replied in a childish voice before turning her attention to the school in the distance. Her face grew worried as she thought of the multiple different outcomes her plan could have, "Shirone, please understand"
A few hours later
A bell signalled the end of another school day before hundreds of kids filtered out through the gates of Kuoh academy. It took a few more minutes but eventually when all the normal students had left Rias and her peerage finally came into view.
"I see so still no luck in finding out what your brother is hiding?" Akeno asked her best friend who currently had a cloud of depression over her head. "It's not just the fact that he hiding something, there's also the problem that since he's forbidden me from returning I haven't been able to return home once to get any of my things and bring them to Issei's!" Rias screamed out making Kuroka snicker at the redhead.
"Once a pure blood, always a pure blood; jeez, getting upset over not having some of your luxuries how pathetic" Kuroka thought as she readied herself to carry out her plan. She just hoped that no-one had discovered the portal that she travelled to the underworld to set up or this plan was going go south fast.
"Cheer up prez, I'm sure I'll be able to find you something in the meantime" Issei declared before a lecherous look made its onto his face, "And in return I hope you'll give something for my good deeds" Issei's voice just dripped with a perverted tone which didn't go unnoticed by the two nekomata's who simultaneously said "Pervert" in a very harsh and cold tone but it didn't seem to faze the brown haired teen at all.
"At any rate Issei how's your sacred gear been acting?" Xenovia asked curiously while getting closer to Issei earning her two glares from Akeno and Rias, "Not much difference thanks for asking by the way; Even though I can still communicate with Ddraig and use my sacred gear I can't get my balance breaker to activate, it's like its refusing to obey me" Issei replied peeking Kuroka's interest who decided to stay hidden a while longer to see what other information the group would unknowingly divulge to her.
"Don't worry Issei as soon as my brother allows us to travel to the underworld again I think I know, or at least my brother knows someone who could help with that problem" Rias said in a reassuring tone causing Issei to quirk an eyebrow. "That's great and all but I'd like to know why it isn't working" Issei said scratching the back of his head, "Well I believe there's only one way to look at it; during your fight with Vali while using your balance breaker you absorbed a piece of his armour onto your own. This is most likely a repercussion of the two dragon emperor's power mixing in the one vessel, so until the white dragon emperor's power has completely left your system I can only assume you won't be able use the balance breaker" Rias summed up and just as she finished Issei's left hand began glowing green.
"I suppose I never thought of it like that" a deep voice suddenly said causing Issei to jump a bit, "Ddraig?!" "Indeed, It's true what she says partner, our power and that of the vanishing dragon should never mix even if only for the briefest of moments; our powers are opposites and existing within the same body can be fatal for our vessel. Honestly it's a miracle you survived, I'll admit I did gamble a bit on you being able to pull it off" Ddraig revealed with a nervous chuckle causing everyone's jaws to drop and their faces to ghost.
"Ddraig! you stupid bastard you realise if I die then you do to?!" Issei shouted in rage at his left arm once again causing Ddraig to chuckle nervously, "Yeah my bad; but perhaps we should continue this another time partner right now we have company" Ddraig's voice suddenly turned serious putting everyone on edge as they looked around frantically, they couldn't sense anyone.
"I was hoping of catching a little more of your show but I suppose it wouldn't really change things now would it?" an all too familiar feminine voice spoke causing Koneko to freeze up. They all looked up only seeing a shadowed figure in the trees before it suddenly jumped down leaving them all frozen for different reasons, Rias and most of her peerage bar Issei, Asia and Xenovia knew who this was from the wanted posters of her placed all over the underworld. Koneko knew well because she was her sister and well Issei, well he was just Issei.
"Holy crap look at the size of her boobs!" Issei shouted out in amazement making a look of disgust make it way across Kuroka's face, meanwhile with Natsu at this exact moment. "For some reason I feel the need to punch something…or someone, really fucking hard" the pinkette said through gritted teeth.
"What are you doing her Kuroka?" Koneko demanded in a strong tone causing her sister to smirk slightly, "My, my such a tone is unbefitting of you…Shirone" Kuroka replied making sure to emphasis her real name. "Koneko how do this person know who you are?" Issei question while also reading his sacred gear. Rias looked on at Koneko with sympathy as said girl gritted her teeth.
"Her name is Kuroka…and she's my sister" Koneko revealed shocking everyone bar Rias who already knew. "Judging by their faces I'm guessing you never told them about me, Shirone you're gonna make you big sister cry" Kuroka feigned tears of sadness although on the inside she was hurting from having to put on this bad guy façade.
"Stop calling me that my name is Koneko, now answer my question why are you here? Why did you suddenly comeback after killing our master!" Koneko shouted at Kuroka who internally cringed at the tone her sister used while the other members of Rias' peerage were shocked further before they readied themselves for combat. Lightning started to crackle around Akeno's hand, "So she's a stray then, well that makes things a bit easier" Akeno said in a sadistic tone causing a shiver to run down Issei's spine.
There was silence for a few moments before Kuroka finally let out a sigh, but her expression had done a one eighty and turned deadly serious as she began radiating her magic power which exceeded that of what the wanted poster described. She wasn't radiating the power of an SS-class devil, it was higher probably closer to ultimate class which meant bad news for Rias and her crew.
"Why tell you when I can show you!" Kuroka shouted before launching herself with incredible speed that even Kiba or Xenovia couldn't follow. Kuroka raced right past them without even giving them a chance to move, "Koneko!" Issei shouted when he noticed his white haired junior was not in sight. "Sorry but I'd like to borrow my sister for the moment, but I'm using the term borrow loosely here; I mean I'll be keeping Koneko for an unspecified amount of time" Kuroka said before once again she took off at great speed towards Natsu location.
You would be wondering why Koneko wasn't protesting much to her sister kidnapping her well that would be because in the process of swiping her younger sister Kuroka had also managed to place a sleep spell on Koneko.
Easing off the speed Kuroka came to the place she left a calm and patiently waiting Natsu, however when she returned she saw the results of Natsu' 'patience'. The place was littered with small fist shaped holes in the ground that were burnt around the edges. She could only sweat drop at the sight before her now, Natsu looked to be very depressed and bored as he sat crossed legged using a small stick to draw something in the dirt. "*Cough* I'm back" Kuroka said while ruffling the dragonslayer's pink hair causing him to jump to his feet.
"Alright now we can get to phase two of the plan, man I can't believe I was waiting there for hours" Natsu droned out, "It was twenty minutes at the most" Kuroka said quirking an eyebrow before Natsu made his 'doesn't matter to me' face. "Twenty minutes a few hours, same thing really" Natsu replied causing Kuroka to shake her head, looks like his math would need work.
Natsu then noticed Koneko sleeping on Kuroka's back making him smile, "Wow when I look at you two like this I can really tell you're sisters, It isn't that you look like one another in fact you're complete opposites but I can't help but get this feeling of yin and yang about the two of you" Natsu said as they made their way to Kuroka's portal making the older sister smile in the process, "Well I always did think of Shirone as my better half" Kuroka spoke in a soft and kind tone as she set her sister down on the ground in front of them before the trio were engulfed in a bright light as they made their way to the underworld.
A few moments later Rias and her group arrived but alas too late as the portal had already closed, "Damn they must have gone to the underworld, I have no choice I'll have to disobey my brother; Akeno help me try and re-open this portal" Rias said before she noticed that Issei had wondered off to the side. "Pres I think you should see this" Issei said in a worried tone when he sensed the magic coming from the area in front of him. Now if Kuroka paid more attention she would have noticed the singed lawn of grass that specially spelled out 'THE END WILL COME'.
In the perspective of Rias and her peerage it was quite an ominous message but from the perspective of the message's creator who was just bored stiff and the end he was referring to was that of his wait for Kuroka to return. "I don't like this; it was definitely magic that caused these burns but I've never felt magic this sinister before nor anything like it" Rias spoke in a worried tone as she examined the grass in front of her.
Meanwhile in the underworld
In an unknown location of the underworld a large magic circle glows on the ground before it reveals Natsu, Kuroka and a still unconscious Koneko. "Man that went a lot smoother than I thought it would" Kuroka said with a sigh before her attention moved down to her unconscious sister lying on the ground. "How you holding up?" Natsu asked in a concerned tone as he picked up Koneko, "Well my magic is still doing pretty good I think I'll be okay" Kuroka said with a smile feigning any emotional worry causing Natsu to frown.
"You know that isn't what I meant, tell the truth" this time Natsu voice was stern resulting in Kuroka clenching her fists. "She hates me" the nekomata simply replied which resulted in a confused making its way onto the dragonslayer's face. "What?" he asked in a clueless tone, "She hates me, the way she talked she just hates me for abandoning her!" Kuroka was on the verge of an emotional breakdown as her body stiffened up and tears pooled in her eyes. It did Natsu no good to see his mate like this, not that it did him any good to see anyone like this.
"How can you be sure; did she actually say the words I hate you?" Natsu asked in a gentle voice, "Well, no but…" Kuroka answered but before she could explain further, "Well there you go, if she hasn't actually said it then you can't be sure; when she wakes up you'll be able to find out everything you need" Natsu spoke in a cheery tone slightly lifting Kuroka's spirits. Although she was afraid to find out what her sister actually thought but now her fear was less than before because she had Natsu with her.
Wiping any tears from her eyes Kuroka's resolve returned, "We better find a well-hidden area, it won't be long until Shirone's friends arrive looking for her" the nekomata explained earning a nod from the dragonslayer before they ran off in a random direction. After a few minutes they came to an old derelict building that appeared to be slowly decaying. "Man what a dump, makes my old place look like a five-star hotel" Natsu commented when he saw said building before hearing a groaning sound causing him to crane his neck back around to see that Koneko was beginning to wake up from her sleep.
Going to a nearby tree Natsu set the young nekomata against it before turning to his mate, "I'll give you two sometime alone while I look around to make sure the area is safe" Natsu said with a smile getting a nod of appreciation from Kuroka, "Natsu, her friends are undoubtedly going to come for her and start a fight with me; their important to her so I want you to hold yourself back from fighting them unless it completely necessary" Kuroka said shocking Natsu greatly, she was asking probably the one thing that would be impossible for him to do, but Kuroka was pleading for him to comply, so albeit reluctantly, "I-I'll try" Natsu answered making Kuroka smile before placing a kiss on the dragonslayer's cheek.
"That's all I'll ask of you; now you better hurry up and skedaddle, she's almost awake" Kuroka said as she flicked Natsu on the forehead before he disappeared into the treeline. "Uugghh…w-where am I?" Koneko asked groggily as she rubbed her eyes.
"Shirone" hearing that voice immediately put the white haired teen on edge which caused a great amount of pain for Kuroka. "Please Shirone I need you to listen to me" Koneko narrowed her eyes upon hearing her sisters pleading tone. Never before had she heard her sister as far as she could remember beg before. "Why should I? after everything you've put me through?" Koneko asked in a mixture of emotions but the most prominent was anger.
"I of all people know I have no right to ask for you to hear me out, because of me you've had a hard life but at the time I saw it as the best option" Kuroka started but was interrupted when she heard a scoff come from her sister. "Really? If that was in your opinion the best option then what were the others, what were they that they were so bad that you deemed leaving me behind only to nearly get executed a better option!" Koneko shouted at her sister tears now in her eyes.
However, Koneko had to jump back when she felt her sister's magic power spike, "WHAT! WHO TRIED KILL YOU!" Kuroka shouted in pure rage as the earth beneath her feet cracked and her crimson red and black lotus marking to glow which alerted Natsu of her emotional state. Koneko was frightened by the amount of magic power her sister was emanating as well as the killing intent felt.
"It doesn't matter now, Sirszech and the president helped me" Koneko steeled herself before speaking up, luckily Kuroka calmed down and reigned in her magic power. "Whether you believe me or not Shirone this was the best option, if I hadn't killed our previous master when I did; you would have been subjugated to the same torturous experiments as I myself and I could never have let that happen to my precious little sister" Kuroka said without any hints of lies in her voice.
"But why abandon me then, if that was the case then you could have taken me with you and we wouldn't have been separated, I wouldn't have spent all this time hating you?" Koneko asked unaware of the tears starting to fall from her eyes which got the same reaction from her sister. "I wanted to, I did but I couldn't allow you to live the live the life of a stray constantly on the run in fear of death…" Kuroka started before pausing a taking in a breath.
"I didn't have many options, I could have done nothing and let him experiment on you which would have most likely resulted in your death, kill him resulting in me becoming a stray and leaving you behind for safety or take you with me where there was almost a certainty that either one of us would die; naturally I choose the option that I believed presented the best outcome" Kuroka continued before she wiped away her tears.
"S-so you're telling me that you became the bad guy just so that I could live a life where I would wind up hating you for my entire life~?!" Koneko asked in disbelief causing a cross between a frown a smirk to make its way onto Kuroka's face. "I suppose that sums up what I did perfectly" Kuroka replied in a slightly amused tone causing Koneko to grit her teeth in anger, "HOW CAN YOU BE SO STUPID!?" Koneko snapped surprising Kuroka greatly as she had never once heard her little sister snap like this before.
"Do you realise how much pain you've caused me over the years, after our parents died you were the person who meant the most to me; I looked up to you, even aspired to be like you! If you had told me your reasons for killing our master I wouldn't have cared, all I would have wanted was to be with my sister!" Koneko shouted in a mixture of anger of sadness before she was enveloped in a hug by Kuroka.
"You're right I am an idiot…but I can't change the past, what's done is done; I'm a criminal and it no matter how much I want it we can't walk side by side with each other" Kuroka's voice was apologetic but turned solemn towards the end making Koneko tighten her grip on her sister. "No there's definitely something that can be done, if I explain things to the president she can talk to…" "It's too late Shirone…I'm sorry, please just remember that your big sister will always love you"
"What do you mean…ugh" Koneko went to ask but upon feeling a sharp pain in the back of her neck she fell unconscious in Kuroka's arms, said nekomata was having a hard time keeping her emotions in check, "I'm sorry no good will come from you staying with me" Kuroka said in a crackly voice. Gently setting her sister back up against a tree Kuroka proceeded to set up a barrier to keep her safe before she decided that she better get out of her before the red head and her peerage show up.
However, as Kuroka reluctantly left her sister behind she almost immediately had to dodge a crimson bolt of destruction magic. "Tch, I was hoping I would have to deal with you lot" Kuroka spoke in a rather annoyed tone. "What the hell did you do to Koneko!?" Issei shouted while sporting his boosted gear making Kuroka smirk.
"What's so funny, we clearly have you at a disadvantage here?" Rias asked not liking the way that it appeared Kuroka was looking down at her and her peerage. "What no balance breaker, I believe you're greatly underestimating me… or is it that you're just too weak to use it?" Kuroka asked smugly causing Issei to grit his teeth, "I don't care if you're a smoking hot babe you're going down!" Issei shouted before his gear glowed green and he charged toward the still smirking Kuroka.
"Issei Wait"
"BOOST! DRAGON SHOT!"
Gathering the energy in his hand Issei threw he boosted green orb at Kuroka who much to the others surprise remained in place and simply waved her hand causing a disturbance in space that swallowed up the attack like it was nothing.
"W-what just happened?" Issei was beyond perplexed at seeing his attack seemingly disappear into thin air, "Oh it isn't gone" Kuroka said with a smirk causing Rias and Akeno's eyes to widen, "Issei watch out!" they both shouted before a pocket of space opened up beside Issei revealing his attacks resulting in an explosion that sent the brunette into a tree a couple of metres to his side.
"I really would prefer to end this without violence considering you are my little sister's friends" Kuroka said in a bored tone before she randomly started teleporting around the area at great speeds. "You bitch, don't give us that crap; your gonna pay for that!" Kiba shouted as both he and Xenovia drew their swords and chased after the nekomata, followed by Rias while Akeno and Asia attended to Issei.
Meanwhile Natsu although he was struggling to keep himself in check especially whenever Issei said something that either referred to Kuroka's body or insulted her, he was somehow managing to hold himself back and remain undetected while he just simply watched as Kuroka dealt with Rias and her peerage taking them out one member at a time in the quickest most efficient way.
In a matter of minutes only Rias and Akeno remained standing albeit barely, while Kuroka had barely a mark on her, she herself didn't know when she had become so powerful but she was liking it. "You know from everything I heard I had expected a lot more from you considering you were The Crimson Satan's little sister; but I guess that was before I factored in the dragon's powers flowing through my veins" Kuroka revealed causing the duo eyes to widen at the mention of a dragon's power, not only them but Ddraig was surprised at the mention of a dragon.
"Partner can you hear me, stand up you must" Ddraig practically commanded his host making Issei shakily push himself off the ground, "D-Ddraig?" "If you want to use the balance breaker do exactly as I tell you" the dragon said before instructing Issei to do something he was more than happy to comply with.
Now both Natsu and Kuroka had seen many things in their lives, but never had they seen someone take such great pleasure in the perverse act of touching someone's nipples. Yep Ddraig instructed Issei to poke Rias' nipples, that was what he had to do in order to use the balance breaker and it worked like a charm.
"Okay weirdness aside things might be a bit more interesting now" Kuroka said with a smirk although this one was different from others, her time with Natsu short as it was had caused more than a few of his traits to rub off on her such as his childishness but right now his love for battle was what was shining through
"I am the Red Dragon Emperor, the dragon of Domination and I shall defeat you!"
Chapter end
Okay an abrupt end but I felt that if I made the chapter any longer it would have disrupted the way the chapters flowed. I hoped you enjoyed this chapter and if you have any ideas for this story or my other stories for me to take into consideration then let me know. Until next time
