"Um... I think I've extracted Chakra..." Tokito Muichiro murmured softly.
Unexpectedly, after giving him the Chakra seed, Muichiro was the first to extract it, even Tanjiro couldn't do it.
Mist Pillar Tokito Muichiro is a descendant of Kokushibo, the user of the Starting Breathing, Moon Breathing, and a genius who became a Pillar in just two months of wielding a nichirin blade.
And Kokushibo was the twin brother of Sun Breathing. Due to his inability to resist the temptation of immortality and jealousy, he willingly fell and became a Demon, leaving behind descendants before he transformed.
But because he lost his memories, he lacked emotions and was cold to others. However, it wasn't that he lacked emotions, but rather that he didn't know how to care for others. To put it plainly, in modern terms, he was a shut-in, a tsundere.
If there wasn't a chatty and adorable person actively seeking him out, this reserved person would probably be a bachelor for life.
"Let me see. Run it, extract a wisp of Chakra." Uchiha Nagi stood up, walked over, and said, placing a hand on his shoulder.
"Okay~" Muichiro immediately closed his eyes and began to extract Chakra according to the method Mr. Nagi had previously described.
A faint energy, completely different from Breathing Technique, began to appear in his body. Mr. Nagi keenly sensed it.
"That's right, it really is Chakra. You truly are a genius…" Mr. Nagi's eyes widened in disbelief. In just one day, he understood it from scratch and then extracted Chakra. Such a thing as genius truly exists…
"Ah, so I succeeded?" Muichiro asked blankly.
"Yes, you succeeded. Come outside, I'll tell you about the Three-Body Technique. See if you can perform it." Mr. Nagi walked out into the courtyard and demonstrated the Ninja Three-Body Technique.
The Three-Body Technique is a basic Ninjutsu, the lowest-level technique that even Ninja elementary students can use. It's easy to learn and consumes little Chakra, but mastering it can save one's life.
After Mr. Nagi explained it to Muichiro for a while, he formed hand signs and performed it once, then let Muichiro try it.
"Then I'll give it a try~" Muichiro said softly, closed his eyes, and thought for a moment… Bang~
Body Transformation Technique completed—
Bang~
Clone Technique, completed.
Bang~
Body Replacement Technique, completed.
Since he didn't have a replacement log, what was left in his place was his nichirin blade.
Mr. Nagi: "…"
Shinobu Kocho covered her mouth and chuckled softly, "Although Mr. Muichiro is young, he is the fastest genius to become a Pillar, taking only two months from joining the Demon Slayer Corps to becoming a Pillar."
This time, Mr. Nagi directly taught him the Shadow Clone Technique. Muichiro listened for a while, tried it this time, and finally didn't succeed… "It's okay, you'll learn it with a few days of practice~" Mr. Nagi smiled, the corners of his mouth upturned.
"Oh, okay. By the way, the Master told me to teach you Mist Breathing. Do you want to learn it?" Muichiro asked, scratching his head.
This silly child, does he even need to ask?
"Yes, please demonstrate it once, Mr. Muichiro~"
"Oh~"
Muichiro is reserved and doesn't talk much, a genius as such—
He began to wield his nichirin blade, releasing Mist Breathing:
[Mist Breathing · First Form: Hanging Skyscape Distant Mist]
[Mist Breathing · Second Form: Eightfold Mist]
[Mist Breathing · Third Form: Scattering Mist Spray]
[Mist Breathing · Fourth Form: Advection Slash]
[Mist Breathing · Fifth Form: Sea of Mist Clouds]
[Mist Breathing · Sixth Form: Lunar Dispersing Mist]
During Muichiro's demonstration, Shinobu noticed that Mr. Nagi's eyes had turned red, and a plum blossom-like pattern appeared in his pupils. She couldn't help but be shocked. Can human pupils change their appearance?
If it weren't daytime, Shinobu Kocho would have suspected that the other party was an infiltrator sent by Muzan. She had never heard of human pupils changing.
The Mangekyo Sharingan, at this moment in Mr. Nagi's eyes, perfectly copied every movement and every breath of Muichiro and stored it in his mind. In contrast, his Mangekyo's ocular power was constantly being consumed.
Mr. Nagi realized that the more powerful the skill, the more ocular power it consumed to copy. Because when Muichiro used the last form, the ocular power consumed for copying was several times more than for the previous few moves.
Fortunately, he has white zetsu cells, so his ocular power can recover… It's a pity that Muichiro at this time has not yet created the final move of Mist Breathing, [Mist Breathing · Seventh Form: Obscuring Mist]. Otherwise, this set of Breathing Technique would be perfectly obtained. But there's no rush, there's plenty of time.
"Hmm, Mist Breathing is basically like that, Mr. Nagi, have you learned it all?" Muichiro asked, scratching his head, looking completely self-assured.
"Mr. Muichiro, you think everyone is like you, able to learn it just by watching once, hehe~" Shinobu Kocho covered her mouth and chuckled softly.
Mr. Nagi nodded, "Yes, I've learned it…"
Shinobu Kocho: "…"
Was that too quick of a slap to the face? But seeing the two of them look so self-assured, Shinobu Kocho covered her forehead. Was she too useless, or were these two too much of geniuses?
Mr. Nagi performed Mist Breathing exactly as Tokito Muichiro had, demonstrating it perfectly from beginning to end. Shinobu Kocho was so astonished her jaw dropped.
"Mr. Nagi, you're even more of a genius than I am! You learned it just by watching once. Compared to that, I'm really terrible, sigh~" Muichiro sighed dejectedly.
If not for the protagonist's halo, Muichiro would definitely be the protagonist of this world, a genius far surpassing Tanjiro, and the person most likely to eliminate Muzan, given enough time to grow.
You are a true genius, and I am a cheating genius… "However, Mr. Nagi, the Mist Breathing you performed, I always feel it's a bit strange. It seems to only have the appearance, without much power." Muichiro stroked his chin, staring blankly at the white clouds.
"Yes, I only copied it. Once I thoroughly understand it after some time, I believe it will be much better." Mr. Nagi said helplessly.
Breathing Technique is not just breathing; it's combined with sword skills, unlike Ninjutsu which is so singular. And sword skills, that's something profound. The same sword skill used by different people will have different power.
So far, the most proficient Breathing Technique Mr. Nagi uses is Tanjiro's Water Breathing, after all, a person's daily training time is limited, and it's impossible to attend to everything.
"Then I shall take my leave first. I will come to ask for your guidance again tomorrow after I learn the Shadow Clone." Muichiro bowed politely and left.
If not for his reserved personality, he would be a quite likable child.
"Oh my, Mr. Uchiha is truly amazing. He actually learned Mist Breathing just by watching once. I wonder if you can learn all the Pillars' Breathing Techniques?" Shinobu Kocho asked curiously.
"Learning all Breathing Techniques isn't a problem; the difficulty lies in deducing the Breathing Technique that best suits oneself from them."
