"What can you do?" I asked foolishly while staring at Mai with wide eyes.
"Turn into a sword." Mai repeated easily, and I just stared at her dumbfoundedly. She can do that? Was Mai a freaking demon weapon from Soul Eater? I mean, that kind of quirk wasn't uncommon in this world, but Mai having that kind of quirk really caught me off guard.
"Is there a problem?" Maki asked, frowning. "Mai's quirk isn't particularly rare; while most attend Shibusen, not all do," Maki said defensively.
"No, no, no, no problem," I said immediately. "It just... caught me off guard," I said honestly.
"That idiot saw something different with his future vision than your quirk. I told you not to rely on it completely." My mother, who had been silent until now, mocked.
"Vision of the future?" both twins asked at the same time. I grimaced.
"First of all, I don't entirely trust my vision of the future; I know I don't see everything exactly the same." I complained to my mother before looking at the twins. "And yes, something like that. My Observation Haki is so developed that I can see several seconds into the future, but also, sometimes I get these... flashes of a person's future or past when I see them. I saw a few things about both of them, which is why they knew they were the best option." I said honestly—well, as honestly as possible, sticking to the story I had put together so far.
"What did you see?" Mai asked, frowning.
"Maki killed the entire Zenin clan alone, without my help," I said honestly. The two sisters and my mother's eyes widened in surprise.
"Wait, if I was able to do it in that future, then— "
"After Mai died trying to save you from the wounds your mother inflicted." I interrupted Maki with my voice devoid of all emotion. The words died in her throat as she turned completely pale. Mai also turned completely pale. The pair stared at each other for a few seconds. Neither of them even thought I was lying. They truly knew Ougi would be capable of doing it.
"That damned bastard." My mother growled through gritted teeth.
"What else did you see?" Mai asked tremulously, I shook my head.
"No matter how it happened, that won't happen again." I said easily.
"How do you know that?" Maki growled furiously.
"Because I'll kill them before they do it if necessary." I said coldly as I looked at Maki. Maki stared at me before nodding and crossing her arms.
"Fine, I want to beat them up myself, but if they touch Mai, destroy them," Maki growled. I sighed wearily. Mai blushed slightly.
"Even so, as I said, I had seen something else in Mai, another skill, it was called Construction, she was c-"
"Did you see that?!" Mai squealed incredulously, Maki turned to look at her in surprise.
"Wait, you have another quirk?" Maki asked, sounding excited and happy for Mai. "Why didn't you ever tell me?" Mai asked, offended.
"You know why." Mai hissed. Maki grimaced again, looking away. "What did you see?" Mai grumbled, staring at me. I shrugged.
"Construction lets you create objects out of thin air, but it uses too much... aura, I guess, it's extremely inefficient." I hummed, and Mai clicked her tongue.
"Worse than inefficient, creating a single bullet consumes all of my pitiful Aura. If I try to use my quirk without aura, my body starts having strong rejection reactions. It's completely useless." Mai grumbled dejectedly. Maki frowned worriedly.
I… couldn't disagree and agree more at the same time. It really was a shame that Mai had so little Aura; Construction was terribly inefficient in its consumption, one of the most annoying techniques there was, but it wasn't a weak quirk by any means.
She had told the rest of the class that she had a weaker version of Yaoyorozu than Creation, but that was completely false; she didn't even come close to what Construction really was.
Creation was capable of creating anything that existed, as long as it knew its composition and everything related to it. There were limits, certainly, but it could only create anything physically possible.
Construction? It went a step further. Even considering only Mai, it was truly special. Despite it costing her her life, she was able to recreate Split Soul Katana. At no point was it mentioned that Mai had seen or studied said katana; she simply created something identical to Split Soul Katana without even seeing it. It's quite possible that Split Soul Katana was a possession of the Zenin, as in this world, and it's possible that she was able to read something about it there, but overall, it was something truly unknown to her.
And that wasn't all; most importantly, she had replicated it perfectly. She was able to replicate a cursed tool, a cursed katana capable of bypassing all physical durability and cutting through the soul. She was able to create something that should be physically impossible.
If it weren't for its complete inefficiency in consumption, Construction would simply be ridiculously powerful.
You only had to look at Yorozu, the other person with the Construction technique within the JJK universe, but unlike Mai, Yorozu had a large amount of cursed energy capable of keeping up with her technique.
She was able to reproduce almost any substance she knew, she could build armor and weapons alike, at some point she created a special liquid metal, capable of controlling it with cursed energy to attack at medium and long range.
She was able to create insect parts, such as insect wings, that didn't even appear to be attached or protruding from her body; they simply attached themselves near her back like a cursed tool that worked perfectly for high-speed flight. She was able to create a biological armor with numerous biological functions from different insects to overcome her own weakness.
And most importantly, and absolutely insanely, Yorozu was able to create a damn true sphere, a perfect sphere that is theoretically impossible. A sphere without any irregularities, capable of generating infinite pressure, making it untouchable. I didn't even know if physics would work that way even if such a sphere existed, but Yorozu made it work that way.
That's how powerful Construction really was if it could be used correctly.
It was a shame that Mai didn't have the necessary Aura to do it.
But… but I did. Normally it would be impossible to share Aura, but pairs of Meister and Weapons—a person who wields the weapon and a person with a weapon quirk—were the most compatible when it came to performing a soul resonance. That was something I had already partially achieved when the girls tried to push their Aura into me to release my Shikigami.
If I could do that with Mai, she could use my Aura to feed her weak Quirk. My Aura was completely through the roof; I had so much it was ridiculous. Even if I used it to activate Ten Shadows during a fight, I'd still have way too much Aura left over.
That… would be feasible, plus there was the fact that having a person who could become a weapon would increase my power level to another level. A Meito, or a weapon made from monster parts, could rarely compare to a person with a perfectly trained weapon quirk.
There were fundamental differences besides being able to use techniques like Soul Resonance that exponentially multiplied the strength of both people.
But… would Mai let I use her as a weapon? Was it something she would want? She didn't want to get involved with anything involving heroes and hunters, just like her canon counterpart.
Even if she were willing, would we have enough compatibility to use her? People with weapon quirks were truly special, not because they were rare, but because they couldn't be used by just anyone.
It was well known that a person who becomes a weapon relinquishes complete control of their body to the person who manipulates them. This required immense trust and compatibility; the weapon instinctively generated a kind of protective aura that made it impossible for any incompatible person to handle it without triggering dangerous reactions.
"Do you want to be my weapon?" I asked before I realized it. Mai's eyes opened slightly.
"Do you want to use me?" Mai asked incredulously.
"Only if you want to. You said... that you didn't like this life, the life of a hero and hunter. I'm not going to force you into anything, but if that's what you want, I'd like you to be my weapon," I told her honestly. Mai looked at me in surprise, unsure how to react.
"Y-you don't even know if we're compatible!" Mai hissed, blushing slowly. I smiled gently.
"Well, we could find out," I said, trying not to sound too enthusiastic. "We can go train, and while we're at it, I could spar with Maki and see what level she's at." I said playfully, glancing at Maki; her eyes sparkled slightly.
"I hope you have a weapon in this house," Maki said savagely. I just nodded and looked at Mai once more; she gritted her teeth.
"Let's give it a try," Mai finally said, and my eyes sparkled with excitement. "That doesn't mean anything! I just want to know if we're compatible! That doesn't mean I'll be your full-time weapon! " Mai said immediately. I smiled broadly as I stood up.
"Let's go!" I said cheerfully as I headed toward the backyard. Once I was in the yard and my shadows stretched out, dozens of weapons began to emerge from the ground. Most were swords of varying lengths and shapes, but there were a few other different weapons here and there.
"I'm really jealous of your quirk," Maki said, completely amazed as she looked at the weapons on the ground. "It's a shame you don't have as many polearms," Maki sighed, but she bent down and picked up one of the katanas from the ground, swinging it a few times as she nodded. I looked at Mai, who approached uncertainly.
"By the way, I suppose the Zenin Clan knows about your quirk that allows you to turn into a weapon? Has anyone been able to wield you? " I asked curiously. Mai shuddered as she grimaced.
"No, luckily none, and they forced me to try it with every member of the clan." Mai grunted, shuddering before falling silent. "Only... one person was able to wield me." Mai said before glancing in Maki's direction. Maki looked away, embarrassed.
"I guess that didn't end well," I said with a grimace. Mai grunted in annoyance before sighing.
"Let's end this." Mai said before she began to glow and transform into a katana in mid-air before falling to the ground and plunging into the earth.
I looked at the katana Mai had transformed into.
Its length was average; the tsuka, its handle, was wrapped in dark green threads like Mai's hair, forming a Hineri-maki braid, the classic diamond pattern along the entire handle. The blade length was as promised, and its hamon, the visible pattern on the katana's edge, was Suguha, the classic straight and smooth pattern, while the handguard, the tsuba, was a Maru-gata, a completely smooth and simple circular handguard.
There was no decoration; it was just a simple katana, almost indistinguishable from the others. It was a decidedly generic katana, almost identical to the ones I had left for Maki to use. There was almost nothing remarkable about it, as if it wanted to camouflage itself, become invisible, trying not to stand out.
I approached Mai almost reverently, slowly and gently grasping her hilt, expecting a rejection, but my hand closed firmly on her grip without any problem.
"Huh?" Mai said, confused, even in the form of a katana, as she pulled it out of the ground.
"Can you really wield it?" Maki asked, sounding genuinely excited for Mai.
"This... is strange. You feel... different from Maki," Mai said, even in her sword form. "You're... completely opposite. You feel really calm, like... like you're an undisturbed ocean, but... I can see that it's capable of becoming furiously turbulent at any moment, and yet your... your aura barely opposes mine," Mai said, surprised. I hummed softly.
That… was weird? I had tried wielding Deflinger once, it hadn't gone well, I could feel the rejection immediately. This… wielding Mai felt right. Mai was right, our auras didn't repel each other at all. I didn't know if it was because Mai barely had an aura and mine was gigantic in comparison, or if my Selfless State was doing something strange.
Or perhaps we were simply really compatible.
"Let me... let me try something." I said slowly, slowly pushing my Aura to envelop the sword. Mai didn't put up any kind of resistance even when my Aura completely enveloped her.
"That, that feels good," Mai murmured, almost like a purr. I hummed in confirmation; our auras were compatible, but we hadn't yet reached the point where we could make our auras work together. We hadn't even scratched the surface; her aura simply didn't oppose mine, so I could envelop her in it.
I took it a step further and began infusing it with Haki. The whole process was much slower than with my regular swords, but it was working. It was more complicated, required more concentration, more effort, but finally, Mai was completely infused with Armament Haki.
"This... feels like having a freaking energy boost. I... feel invincible." Mai murmured in amazement.
I lifted Mai into the air and began to swing her lightly. Before I knew it, I was dancing Sun Breathing with Mai in my hands. The dance steps came naturally as I moved Mai from side to side with all the finesse of years of practice, the hundreds of thousands of times I had done these steps.
Mai moved with ease; with each dance, I could feel Mai adjusting more and more until it reached a perfect point where I was completely one with Mai.
"Sun Breathing: First Form – Dance."I firmly grasped Mai above my head and forcefully pulled her down, still enveloped in haki. My haki continued to spread, creating a fissure in the ground nearly twelve meters long.
"That... that was incredible." Mai said, amazed and a little shocked. I just smiled broadly.
"Oh... you're wonderful, Mai." I said, completely amazed, a smile growing across my face. My swords were... temperamental. Any Meito was, any weapon that reached that point was.
Sendai Kitetsu was a troubled, savage child with an insatiable thirst for blood and an uncontrollable urge to cut down anything in sight. Enma was ruthless and dominant, devouring aura and haki without mercy. Both were 'cursed' swords, and I needed to constantly master them so they would cut only what I wanted them to cut.
Wado Ichimonji was the complete opposite; serene, noble, and steadfast, the most balanced and pure of all my swords. Yet, it demanded respect and determination; it wasn't something to be wielded carelessly. Even the other swords I had used in the past had their own distinct personalities. Shusui was a veteran, imbued with the will and glory of my grandfather, which gave her a weighty, almost authoritarian presence.
Each sword was unique, each sword demanded different things to use them correctly; it wasn't an uphill battle, but they were demanding and required a strong and constant willpower to master them.
But Mai? Mai was completely different. I could feel her; she wasn't resisting in the slightest. She was letting me lead, settling in, adjusting, and synchronizing with me to such an extent that it seemed like I'd been training with her for years. I could see her becoming one with me as I wielded her with such ease. I smiled broadly.
"What do you say, Mai, do you want to kick your sister's ass?" I asked with a wild smile. Mai remained silent.
"You know what? When you put it like that, yeah, I want to kick her ass, go ahead, Miyamura." Mai said with all the determination and excitement she could muster. I could feel Mai becoming more comfortable in my hands. I smiled broadly. I could see Maki smiling too as she got into a fighting stance.
"Come on." Maki said expectantly.
