Izumi Miyamura: Xover - Chapter 13

October 29th 2xxx – Izumi PoV

"Introductions!" I exclaimed happily, in front of me were 3 people, two girls and a boy "This is Taylor, my fiancée." present while pointing at Taylor.

"Hello." She nodded, I could feel her pushing her shyness to her bugs.

"And they are, Kazuto Kirigaya, a good friend of mine for years and his cousin Suguha Kirigaya." I said as I introduced the other two people, and yes, they were really Kirito and Leafa from Sword Art Online, the spitting image of both of them too.

"Hello, nice to meet you Hebert-san, Izumi has talked a lot about you." Kazuto said with a soft smile.

"I hope nothing bad." Taylor sighed tiredly, I smiled widely.

"But those are the best things, Taylor." She grunted in response, Kazuto letting out a small laugh.

"Relax, only good things, I assure you." I rolled my eyes in amusement as I watched Taylor sigh with relief.

"Hello, Miyamura-san, Hebert-san, nice to meet you." Suguha said as she bowed slightly, Taylor nodded in her direction.

"A pleasure Suguha." I nodded lightly ignoring the slight blush on her cheeks at the casual use of her name, Kazuto smiled amusedly knowing me easily "Now, why are you here! Training! " I clapped excitedly, Suguha and Taylor looked confused, Kazuto sighed tiredly.

"I knew it would be something like this," he muttered.

"Now, now, none of that, it'll be fun." I said with a smile, Kazuto and Taylor grimaced, knowing my funny for me = painful for them "context, Kazuto was the first one I taught total concentration breathing to."

"Really?" Taylor asked surprised, I nodded.

"What you have to understand is that Total Concentration Breathing came to me as something natural, I needed to know if it was something that could be replicated or was it just part of my quirk, something like a secondary quirk, so-" I said while grabbing Kazuto's shoulder "I taught it to Kazuto to see if it was possible, he was my guinea pig, my beta tester or whatever you want to call it and, the results were good, Kazuto learned it after intense training."

"Torture." Kazuto coughed and Taylor nodded vigorously, I was magnanimous and ignored them both.

"Taylor is the second person I've personally taught Total Concentration Breathing to, while Kazuto asked me if I could teach it to Suguha, which was also successful, so, you're going to train ." I clapped my hands "You three are the only people with Total Concentration Breathing, and you're going to measure yourselves against each other, I want to see what level you two, Suguha and Taylor are at, the use of Quirks is allowed, nothing lethal!"

"Hai!" "It's okay." Suguha and Taylor said respectively, both of them took a wooden sword and got into position, Kazuto and I moved away to a safe distance, I could see how Taylor discreetly carried insects to Suguha's clothes and they got inside the folds to avoid being dragged by the movement.

"Start!" As soon as I finished shouting, both of them had already started to move, Suguha summoned four fairy wings on her back, they were transparent green and she propelled herself forward in what I immediately recognized as Wind Breathing , First Form : Dust Whirlwind Cutter , in addition to her wings, Suguha could control the wind, so she dragged the surrounding air creating a cyclone as she propelled herself forward, Taylor brought the insects around her, the swarm grew over the air and darkened the courtyard due to the accumulation of them, I could see Kazuto pale a little but I ignored it, unfortunately the swarm was slow but Taylor still reacted easily to Suguha's attack blocking it from the side.

"So Suguha finally learned Wind Breathing " I said to Kazuto next to me, and I could see him puff out his chest with pride.

"Yes, thank you for the instructions and the sample videos, they were really a big help." she said softly, I shook my head as I watched the fight, Taylor finally arrived with her swarm and enveloped them both in it, Suguha used Fourth Form : Rising Dust Storm to create a whirlwind above and above her destroying the swarm around her, but it was just enough time for Taylor to hide within her swarm to hide.

"No problem, though I'm sorry I couldn't help you personally." I gave him an apologetic smile, he smiled and shook his head.

"Don't worry, it was more than enough help that you let me teach him Total concentration breathing, that alone greatly increases his chances of getting into UA." I snorted amusedly.

"I was going in without that, his quirk and swordsmanship are strong." I felt Taylor through my observation haki use Ninth Form : Splashing Water Flow, Turbulent , was quickly becoming her go-to move, and for good reason, she's also getting vastly better at using it, the speed increasing more and more, she had surrounded Suguha with her swarm that screeched loudly to hide the sound of Taylor as she popped out from a random spot, attacked Suguha, and hid again, moving fast enough to keep Suguha on the defensive.

"Still, thanks, I promise I won't teach anyone else Total Concentration Breathing." I looked away from the fight and tilted my head in confusion .

"What? Why not? " That seemed to take him by surprise.

"Wait what, isn't it like a family secret or something?" he asked timidly and I snorted.

"I told you I made it up."

"Still..." He smiled crookedly, I sighed and turned my gaze back to the fight just in time to see Suguha jump into the air with the air, before pushing herself down and using, Fifth Form : Cold Mountain Wind to cut circularly in all directions and stop Taylor who defended himself from the cut.

"I never told you it was confidential or anything like that." I shrugged. "Yes, it shouldn't fall into dangerous hands and spreading it everywhere would be irresponsible, but I trust you, that's why I showed it to you in the first place, you're my brother." Kazuto looked at me with a moved look.

"Izumi..." I grimaced.

"If you start crying I'll hit you." That made him burst out laughing. "But seriously, if you meet some cute girls who can handle swords the way you like and you trust them enough, teach them, I have no problem."

" E -ey!" Kazuto blushed, I snorted.

"Hell, even your children in the future, if none of the ones you teach suit the styles you know, call me and I'll show them something they have an affinity with, or we'll invite something on the fly." Kazuto blushed deeper, but nodded.

"Thanks Izumi, really." I hummed lightly as the fight continued.

"Don't worry, you did a good job teaching him." Suguha was the one on the offensive now, shape-shifting or simply attacking from the air, she ignored the bugs around her realizing they were more of a distraction than an actual danger, still cutting them down when they were a slightly bigger problem, Taylor despite being able to use her bugs as a makeshift platform, was still no match for Suguha's absolute dominance in the air so she was firmly confined to the ground defending herself or attacking when it got low enough for her to reach.

"Speaking of which, do you think you could..." Kazuto tried to ask timidly, I nodded.

"I'll correct the mistakes in your stance, but there really aren't that many, I already said, you did a good job, there's not much to correct." The praise made him blush in a different way than a few seconds ago but he still stood with pride as we both continued to watch the fight in silence, it seemed that both reached a stalemate, Taylor couldn't hit him reliably in the air and Suguha had the same problems with Taylor on the ground, even so they continued to exchange blows, most of it was a clash of swords but they did sneak in a few blows at each other when they had the chance, at this point it was more of a fight of attrition.

"They're almost finished ." I said simply, Kazuto grimaced and nodded slightly, both still had plenty of aura to continue the fight, but that wasn't what we were seeing, Suguha used another Fifth Form : Cold Mountain Wind spinning from the sky down while Taylor confronted her with a Seventh Form : Drop Ripple Thrust , the thrust met the slashes and at the moment of collision both swords broke stopping them in place, even the bugs stopped as if they were frozen "alright, that's it! it's a draw!" I yelled before they started fighting with just their quirk and fists, both grimaced but still let it go, Taylor led her bugs into the forest while Suguha landed on the ground, both seemed slightly out of breath and somewhat dirty but otherwise were perfectly fine.

"Good fight girls." Kazuto said with a smile as he clapped his hands, both of them smiled back, Suguha more than Taylor, and she was, they were both strong, not at the level that I or Yoriichi would call Hashira level , but they were getting there quickly, they were strong for their age and both had notable room for improvement.

"Now, Suguha, you're with me. I'll correct some mistakes I noticed in your postures. Nothing to worry about, but they should be easier and more fluid for you that way."

" Hai ! Thanks Miyamura- sensei " I snorted amusedly and looked at Taylor who seemed to be staring at Suguha without blinking.

"Taylor, you'll be training with Kazuto for a bit, if you manage to beat him up I'll give you a treat." I winked in his direction and that seemed to be enough to light a fire in his eyes.

"you're bad." Kazuto laughed silently beside me and I smiled back, as it was, it was impossible for Taylor to hit Kazuto, but it was still a good incentive for him to focus "alright! let's go!" with that, I took Suguha aside before starting the lecture, like I said, they weren't bad or that many mistakes, but the difference between learning them correctly from the start and learning them wrong had the consequence of muscle memory working against you, so despite being few, it took almost an hour to correct Suguha enough for it to stick.

Suguha was completely respectful the entire time, something I didn't expect from a 17 year old, I'd been hanging around Taylor long enough to know that they were horny more often than not, which wasn't a bad thing, but Suguha had the discipline to stay focused, her answers were short and enthusiastic, the only time she broke character was when I had to point out and correct her postures in a more direct way which led to having to use my hands to move her body accordingly.

something that Taylor didn't like, Taylor's jealousy every time I touched Suguha was funny, the worst thing was that it wasn't any out of place touch, she would never do that to a friend, Suguha was in love with Kazuto and it was noticeable from a distance and there was a high probability that Kazuto would return those feelings, it was something more than allowed in the society of this world, and besides, NTR was a shitty fetish.

Getting back to Taylor, she wasn't someone who used jealousy on purpose to annoy her partner, it seemed like a childish tactic to me and completely out of place, those who did that had no respect for their partner, so it never bothered me, but we were training so Taylor had to adapt and control herself better, moreover, because she was completely focused on me, Kazuto took the opportunity to hit her directly, and as expected, Taylor couldn't hit him even once in the entire hour .

When we finished, Kazuto and I were cool as a cucumber without a drop of sweat, whereas Taylor and Suguha were sweating profusely and breathing heavily, the only reason they weren't covered in bruises was because of the simple fact that they had Aura to protect them during training.

"Very good!" I clapped happily. "Very good training, both of you!" I congratulated. They both murmured responses tiredly. I just smiled and looked at Kazuto. "Kazuto, always a pleasure to see you."

"We're in the same class Izumi." Kazuto laughed and I shrugged.

"Doesn't change the fact that it's a pleasure." I said simply before looking at Suguha "nice to meet you Suguha."

"Wait, are we done? Aren't you guys going to train? " Taylor interrupted.

"Yeah! I want to see onii -chan fight without holding back! " Suguha suddenly added, I blinked and looked at Kazuto, he just smiled nervously while scratching his cheek.

"Isn't it necessary?... " Kazuto tried, Suguha shook her head repeatedly.

"It's very necessary! I want to know how much I have to improve to reach you! " she said with determination, staring at Kazuto, who squirmed under her gaze before sighing and looking in my direction shyly, I sighed and shrugged.

"Of course, I could use some exercise." I said simply before taking two wooden swords and throwing them in Kazuto's direction who caught them with ease, I was left with three swords, I had about a dozen of these swords, I had learned my lesson years ago, I broke them easily so I had more than enough answers most of the time.

"Three swords?" Taylor asked confused, I nodded.

"I'm better with three swords." I said simply, Taylor looked at me in disbelief, Suguha scrunched up her face in confusion.

"Where... where do you use the third sword?" she asked not understanding the logistics, I laughed lightly before taking a sword to my teeth, both girls looked at me like I was stupid, Kazuto laughed lightly.

"So you're using all three, without holding back then?" Kazuto asked softly, though I could feel his excitement coming off of him, he was also a fight addict, Kazuto was skinnier than me and that was saying something since I didn't have much muscle mass, but still, Kazuto was stupidly strong and fast .

"Of course, if not, there wouldn't be any fun." I said simply, interestingly, Zoro could speak almost perfectly with a sword in his mouth, no double meaning, so that ability was transferred to me, Kazuto nodded, his fairy wings the same as Suguha's appeared on his back, but his were black, and instead of being able to use wind, he could use smoke and illusions.

"Stay away a little." Kazuto warned both girls, who quickly complied, Kazuto got into position, slightly lowering his center of gravity with a sword in each hand, his gaze had focused completely on me, I also got into position, we both waited slightly before giving Kazuto a signal with our eyes, he quickly caught on and we both breathed at the same time, at first it was difficult to breathe properly with a sword blocking the way, but over the years I had mastered it and now I could do it as easily as ever, when we both moved it was an instant clash, we were separated by meters of distance and in the next moment our swords met.

Kazuto was a genius with the sword and he did not say that lightly, although it took time to train him in total concentration breathing, the actual handling of the sword, he mastered it quickly, in two months he mastered the thunder style that I thought best suited his way of fighting, but he had found that the style did not suit him well, so he adjusted the style in such a way that he created his own style, Speed. Breathing .

30, 50, 80, 100 sword clashes happened in a few seconds, Kazuto's blows were fast, accurate, precise and heavy, despite being completely wooden swords there was force behind his blow, I received them with the same speed and force, clashing blow against blow, dodging by millimeter or deflecting his swords while attacking only for Kazuto to respond in the same way, as we continued I could feel Kazuto's excitement grow, the euphoria of the fight grew in him and without realizing it he imbued his swords with his aura, I quickly did the same to prevent my swords from being broken by the new force.

The second round started with the same speed but this time the aura collided and sent shock waves behind us creating cuts around us, as we collided, Kazuto increased the speed with his quirk, while attacking I could see that he used several of the forms of his speed breathing , specifically Starburst Stream and The Eclipse , 16-hit and 27-hit combos with dual weapons, yes, even without Sword Art Online, Kazuto had arrived at the same fighting style by himself inventing the same skills that his canon counterpart would use in the death game.

We continued to clash evenly until the sword between my teeth broke, that didn't stop me, I kept the form of my Aura to use it as a makeshift blade, the same thing happened when one of Kazuto's swords broke, he kept its form while continuing to attack, he didn't even blink at his broken sword, instead he broke the remaining two of mine before I broke his, unfortunately keeping one, if not two or three, Aura swords while continuing to attack with it quickly took its toll and before we knew it Kazuto's Aura was the first to break and that finally stopped us .

"I lost again." Kazuto sighed with a huge smile despite being tired, neither of us was hurt, but our blows had been so strong and so fast in such a short period of time that even with aura it put tension on Kazuto's body, I smiled back with the same intensity.

"you improved your game."

"Well, someday I'll have to beat you, right? " he said mockingly and I shook my head happily, that had been good training, I certainly still held back from using Haki, just like him, but I certainly pushed my body to the limit and it was a nice feeling, at my level it was hard to let go like now.

"Keep dreaming Kazuto." I pushed him with my shoulder and he let out a laugh, we both turned to look at Taylor and Suguha, both were pale looking in disbelief, I let out a laugh that Kazuto replied "Everything okay?" I asked them mockingly waking them both up.

"Y-you- w-what was that?!" Taylor asked forcefully, I shrugged.

"We're training." I said simply and Taylor looked at me like I was crazy and maybe I was, but oh well, sanity is overrated. "Don't worry, they can get there if they try hard." I said honestly, and I meant it, the growth rate of this world was ridiculous and they were far from what was considered the peak of the human being in this world.

"I still have a long way to go to become onii -chan" Suguha bit her lip, but her eyes held a fire of pure determination.
