After I went around and activated each one of their Auras as a reward for proving me they had the mettle to reach where I stood under the intense pressure of Gravity magic along with Conquers Haki working in conjunction to put their bodies under enough pressure to activate their Demon Slayer Marks they were getting a new feel for their Aura.
Each one had there own unique Aura that also consigned with there breathing Technique as well, Rengoku fiery red, Mitsuri flower pink, Obanai snake lime green, Tengen shining silver, Gyomei Earth Brown, and Sanemi a Breezy light green.
I nodded my head, "Good, with this all of you at least stand a Chance against the Upper Moons without major risk of injury, but this isn't enough of a game changer in a way that you will be able to easily kill every single one of them, as you are now you can easily slaughter all the lower moons without issue and only some difficulty dealing with Upper Moon's 6 through 4 but 3 to 1 and Muzan are still a major threat to you all as you are." I said as I went onto explain.
"Your Aura is a manifestation of your own Soul, in battle it can act as a shield to defend yourself from attacks that you yourself are unable to stop, but this comes with a caveat, the more damage it blocks for you the heavier and heavier the mental strain is put upon your body and if it goes on for to long your Aura can break and Shatter, if this happens then in all likelihood you will lose consciousness, and if not you will be barely even able to stand in such a weakened state, and how soon you recover can vary from person to person, but on the battlefield one second is all it takes to lose your life, so assume that if your Aura shatters in a life or death situation, unless you have an ally to cover for you then you must assume death is all but inevitable." I say as they are still getting a grasp on their Auras.
When you are strong enough and have enough of a proficiency with your Aura you can even use it as a Weapon against your enemies causing to become a Semblance, a weaponized version of your very soul given form, and the only thing I can add is that your Semblance will fit you perfectly as I won't be surprised that it will complement your breathing techniques and give you new forms that only you can create, but that is for the future as there is one more thing you need to learn to give you all a real shot at Taking Down Muzan." I say as I look at them as they look back at me intently.
I raise my hand and allow the green spiral energy to flow through and around my arm and across my body, "This is the power of potential, hopes, dreams and the future, this is known as Spiral Energy, any living being has this within them as it allows ones race to grow and develop, it's how humans went from living in caves to building homes, kingdoms and everything leading up until this very point in time, this is Spiral Energy, and it has been the hidden key that has helped humanity evolve and grow throughout the ages." I said giving a rather detailed but still broad strokes on the concept of Spiral Energy since it's simple but also complicated to explain at the same time.
"And as such it is Life energy, and all Life can only exist do to the light of the sun itself, now then I don't need to explain why this energy is so vital in the battle against demons no?" I say which is true as Spiral Energy is in fact Life energy and things that have Stagnated or in the case of demons and undead beings, stopped advancing altogether are unable to use Spiral energy and thus can only use Anti-Spiral Energy if they were taught.
While not on the same level of Hamon that is literal sunlight power, Spiral Energy itself can be considered second to it and as a result this power can give one a great edge in their fight with Demons.
"However, unlike Aura, only you can unlock you own Spiral Energy on your own as every living human being can unlock it, it's something I unlocked before I became what I am now so it's still something I can use and control as a result." I say calming their excitement they I could see begin to burn in their eyes.
"Unfortunately there is a major hinderance in any one human being to be able to use it is mental restrictions they place upon themselves due to the past being what holds them back, things your not proud of, things you can never change, things that have come to define your own mentality as the person you are today, those things are what keep one from ever accessing Spiral Energy, and from what know of all of you do to the aid of my powers, Rengoku is the most likely to unlock it first where as Obanai is the least likely to unlock it, I personally won't bring up your pasts or what happened to you but let's say the level of how much the past is restricted your full potential is based on the chains that have bound you to your past, if I said Rengoku had two chains restricting his body, then Obanai would be restricted by hundreds of chains with the rest of you in between those amounts of arbitrary restrictions." I say to which I can see them all instantly going into a revere state as they looked upon their pasts and things they hoped they could change as well.
"But for now I think it's best you get used to your Aura before we go onto really tackle Spiral Energy, after all I will be around for at least 3 months and at most 6 months to help you all grow and unlock Spiral Energy as well." I went onto explain to them before I began to head back over towards Kagaya and Shinobu who have been watching from the sidelines this entire time.
"I can't thank you enough for imparting your knowledge and powers onto the Hashira, this will be a major aid in our battle against the Demons, though it may be presumptuous of me but would you be willing to help personally in our battle against the demons?" He decided to get straight to the point as I rubbed my chin and thought.
"Hmm, well I guess me and my group can be of aid, however I will say this I will only personally get involved with dealing Upper Moons 2 & 3 while the rest of the Upper and Lower Moons shall be dealt by your Demon Slayers, and when the time comes to Deal with Muzan, which at the rate I see it your slayers will have the power to deal with him before our inevitable departure, only my comrades will aid them as support, and I will only join if everyone is no longer able to fight him." I went onto explain to him.
I wanted that creep Doma dead because I never liked him when I read the story of Demon Slayer and also the fact he was the reason both Kocho sisters died so that pissed me off, and Akaza is more because I want to fight a genuine Martial Artist that I can personally have a life or death battle with to hone my Renweal Taekwondo skills as I could never go all out back home as a result and I just didn't want to unlock access to other worlds without quests, which cost 1 million SP to unlock free access to, just so I could focus on my training.
And another reason why I didn't want to fight Muzan personally is less so I can't beat him and more I don't want the Demon Slayers efforts in all their training for an outside force to come in and fix all of their problems, I mean sure if a demon comes at me I'll kill them in a heart beat but if it's Muzan I'll just side step every attack he can throw my way as from my stats alone I outclass him to the point it's too one sided of a fight if I use Spiral Energy on Yamato while blitzing him with Judgement Cut and thus I will let the Hashira's handle it while I watch the show from the sidelines, and if they all lose I will be a bit disappointed but I'll step in and finish it myself if need be.
He looked at me for a moment before closing his eyes and nodded with a slight smile on his face, "I understand, from what I can tell you don't want the Demon Slayers efforts to go to waste if you came in and cleaned up everything with your strength alone as I feel that if you tried, you could defeat Muzan couldn't you?" He said before opening his eyes and looking at me as I nodded slightly.
"Wait! You could defeat Muzan as you are? But that's just-" Shinobu couldn't help but exclaim before stopping as Kagaya held up his hand.
"He was able to pressure all the Hashira with his mere presence alone to be barely able to reach him and them needing their demon slayer marks to finally pass that hurdle and even help unlock new powers in them, it would be more surprising if he couldn't defeat Muzan as he is, but as he pointed out, Muzan's Death has been the Demon Slayers Goal for over a thousand years, it would be unsatisfying to say the least if an outsider had to come in and deal with him for us, but as he said, if they all fail then he shall join the battle and finally bring it to a conclusion as is." Kagaya went onto explain as I nodded along.
"Speaking of which, I should unlock your Aura as well shouldn't I Shinobu?" I say to which she looks confused and points toward herself.
"Wait me? But I didn't participate in the test." She says sounding confused as I nodded.
"Well think of it more as me doing this for a friend after all, now quit arguing and just accept already." I said as I went towards her and placed my hand on her shoulder before reciting the awakening as her Aura was finally activated just like everyone else.
"This is Aur-ah?! Hey what are you doing?!" She shouted out as I proceeded to carry her princess style out of nowhere as her face began to blush in anger and embarrassment.
"Because we are going back to the Manor, and the fastest way to get there is my way, I mean do you want to run the several kilometers back when we can just get there in a heart beat." I said with a smug look on my face as she got progressively more angry and flustered.
"Well Kagaya when they feel like their ready to face their past, send your Hashira to the Butterfly Manor." I said to which he nodded.
"I will see it done, till we meet again Hifumi." He said as I nodded before looking back.
"Alright you two, let's head on back." I say as Serenity appears nearby before fading away.
*Caw Caw* a crowed Cawed before flying off as I used my shadow to transport myself back towards the Butterfly Manor in no time at all.
"Well, I think today was a rather productive day." I say with a Smile as I let Shinobu go before we both head back inside to call it a day.
