Sword Aura. It's a mysterious energy that I don't fully understand which coats one's weapon to either strengthen the weapon or amplify the force of an attack and add magical properties to a weapon. A technique that only the more experienced ones of the sword or the weapon can use and only a true master of said weapon can fully utilize its mysterious properties.
And yet, despite all of that, he said I managed to do that already?! What the fu-
"Are you sure you are not mistaking this as something else?"
"Yeah, there's no doubt about it, it is the real deal. Well, this is unexpected, I thought you will cast some form of magic to make something of a fake sword aura to start with but when I realized that you were starting to manipulate energy/ki, I couldn't believe my eyes. Also, there was an astronomically large chance that it might not have worked despite you being able to manipulate energy already since it seemed very unrefined but to think you managed to do this at your age, at your FIRST time mind you, is absolute insanity! And you know what…"
What? What is he going to say? I'm getting chills here man! Don't make me feel worse!
"...I'm very proud. This is what I'm talking about! I should have expected this considering you are my brother after all, hahahahah! Since you are able to do this… You must be a very talented swordsman, hehehehe. I should ask mom and dad to increase our time for this class… I never thought I could witness someone of a genius of the sword like me this early, hahahahaha!"
Wait, that's it? Also, is he going crazy?! He wanted to extend the time for this class?! I mean I wouldn't mind since I really would like to learn this type of stuff but I also like learning magic! Also, I like the original class because it teaches a lot of advanced stuff that I could use that will help me live in this world.
Also, there is also the elephant in the room. How the f*ck did I manage to make a sword aura?! I never learned it because I don't understand much about ki and stuff and my [Unique Skill: Knowledge]'s explanations of it are so confusing that I wanted to throw up because of being overloaded in information.
"Answer. It is one of the sub-skill of the [Unique Skill: Swordsman], which is [Natural Swordsman]."
Wait, what? I thought that thing only allows me to use any type of sword naturally and learn them at abnormal speeds, not that it can help me with making sword auras! How did it help me create a sword aura exactly?
"Answer. Because of the passive effect of that sub-skill that enables the user to use a sword naturally, it also means the user is able to learn anything regarding swords including the manipulation of energy to create a sword aura."
What the- I've never heard of that! You should've told me before! So this class is useless then if I could 'naturally' learn things about swords anyway.
"Negative. The user is indeed able to naturally learn and use anything regarding swords. However, the ability to use that specific part of the sword is entirely up to the user's knowledge, experience, understanding, and imagination of said part."
Oh, so this class is not useless then. That's good to hear then. But as I said, you should've told me these things! Goddamn, if I knew that I could learn sword auras this quickly then I wouldn't have wasted so much time these past months. Please tell me the important stuff that I need next time, alright?
"Understood."
It sounded kinda sad. Can this skill have emotions? I thought that this skill doesn't have an ego yet, don't tell me it already developed an ego or is in the process of developing one. Isn't that way too early though?! Also, this skill is making me pity it. Goddamnit. I'm sorry ok? Just remind me of the important stuff, okay? Man, I hope this doesn't cause any trouble.
After my strange interaction with my skill. My brother finally snapped back to reality after being in deep thought of something while laughing. I think I made him crazy. He regained his composure and we continued to class. At first, he just told me to start with simple swings while having a sword aura. It was more difficult than I thought because if I lose focus, the sword aura just disappears immediately and I need to manifest it again, which is easier said than done. I also have to adapt to this weight since the sword seemed a lot heavier whenever I coat it with sword aura. It kinda messes up with the center of gravity a little if I don't thin it out evenly so a lot of concentration is really needed.
After a while, he started teaching me techniques where you can release something of a slash of energy to the air while using a sword aura. I know this since it is so iconic for animes that mainly use swords to use this kind of thing.
I do know it is possible to create something like this without using a sword aura but pure strength and speed using wind pressure or something as long as you swing it at inhumane speeds. I think it must be strong and fast enough like at the speed of sound or something and still would be pretty inefficient as air is really not a good projectile because air freely interacts with itself and also has air resistance so it's like shooting a water gun underwater which is basically useless. Though I think you can do it easily in this world considering magic exists so maybe coating the slash with magicules could do the trick.
Anyway, I should not be thinking about these things right now, I should really focus on what I'm doing right now. We continued making these sword slashes until I was able to create something strong enough to dent the trees. God, this is very weak. But I guess practice makes perfect?
"Ok then, we will now stop the training. That will be all for today! Hmm… what now…"
Wait, we are done? Oh, I didn't realize the time but it is now late. A bright red sun shines on the horizon signaling the sun setting. I stopped and admired the scene. "Wow, this is beautiful." I still haven't fully accepted the whole in another world thing because all of this still can be a dream or something but this, this really is another world huh. I know I can't really call the world peaceful, not in the slightest if Demon Lords like what I know from that sl*me isekai exist in this world, but I'm living a peaceful life right now. It feels great and refreshing. I wonder how long this kind of life of mine will last… I know that I want to become an adventurer when I grow but… well, let's not think about the future too much right now.
"Oh, one more thing! Tomo-chan, have you ever heard of [Origin Enhance] and [Origin Release]?"
Hmm? That's the first time I've heard of that. I wonder what it is. I showed a curious look to my brother and my brother simply chuckled. He then explains that it is a high level of magic or arts, depending on what type you are using, called [Armament Full Control Art] that boosts the offensive power of a magical weapon that is at least a Unique Grade by linking with the true essence of the weapon. It seems familiar.
Anyway, he further explains that most weapons that are Unique Grade and onwards inherit the properties of the object that serves as its nucleus in the form of memories, where it is possible to tap into the parameters inherited from the base materials, therefore increasing the power of the weapon in the form of special abilities. The ability acquired depends solely on how the user pictures the released form of the weapon. Yeah, this is very familiar.
He said that it is divided into two phases, which is the [Strengthening] which is [Origin Enhance], and [Releasing] which is [Origin Release]. The [Strengthening] phase is the partial awakening of the weapon's memories, which manifests as a new offensive ability for the weapon. The [Releasing] phase, however, is the releasing of all of the memories of the weapon, thus unleashing all of its rampant power. Memories unleashed with this phase become uncontrollable to the user and might even engulf the user themselves if they don't understand what they are doing.
Yeah, this is definitely very familiar. I think there was something similar to this but just had a different name… where did I hear this again… Oh, that's right! I think it is part of the third season of that one anime where the main character got trapped into a VRMMORPG death game. I knew it was very familiar. Though I never thought that something like that will be in this world…
When I asked my brother where did these techniques originate from and he said that it was taught by one of the Sword Gods to the first creatures in this world. I wonder if this so-called god is a reincarnated one. I mean it is not too far of a stretch for a reincarnated person to become a god if they have the knowledge, skills, drive, and the power to do it. There is also the case where it is all just coincidence that it is somehow the same name but I don't really care that much.
"Do you know how to use it Aniki?"
"Of course! Although I can't show any of the [Release] phases because it is too strong for a small place like this but I can show one of the [Strengthening] phases."
"Really?!" Wow, I didn't think he would actually let me see it this early.
"Of course! After all, you did show me something interesting this day so I should at least let you see this. I just need to get my weapon for it." He gestured his hand as if he is grabbing a sword in the air and he started to chant something. Suddenly, his ring started to glow and a large red sword appeared in his hand. It is the same sword he used months ago! I mean, that sword definitely looks like something of a Unique Grade weapon or higher.
He then started chanting something which I could barely hear and said: "[Origin Enhance: Flames of Embrace]!" and swung his sword. Slashes of flames started to form and gathered at one spot in the sky immediately followed by a large explosion in which the flames roared and manifested into some sort of shape and started to move as if it is embracing something until it roared one's again and dissipated.
That was so cool! You can actually do that in here?! I want to use that as well! Wow, I think I now have a more profound respect for my brother for showing me something this cool.
"So what do you think? I looked very cool right?"
"Yup, very cool!" It was cool. But I wonder why I said that aloud. Am I becoming more and more of a child? I mean it will certainly help to avoid suspicion but it will be very embarrassing for me if I do. Well, why not? I'm a 5-year-old right now, so I shouldn't worry about things like this, right?
