"Everyone's gone. Aren't you coming out yet?"
As soon as Uchiha Nagi finished speaking, a gentle breeze blew, and a man, as fast as the wind yet traceless, appeared beside Uchiha Nagi. It was the Wind Pillar, Sanemi Shinazugawa.
"He is my younger brother…"
Sanemi Shinazugawa's face was covered in hideous scars, as was his body. Some of these scars were from battles, but a greater reason was that he often cut himself with his nichirin blade to draw blood.
Besides being rare, his blood carried a special ability: anesthesia. Demons who smelled his blood would fall into a drunken state, and the more blood flowed, the more severe the state.
Sometimes he would even intentionally let his blood stain or be ingested by demons to trick them, a tactic that always worked. Unfortunately, it had little effect on the Upper Rank One or Muzan, who were at the peak.
Sanemi Shinazugawa continued expressionlessly, "All this time, I only wished for him to be a normal person, to marry and have children honestly, and live an ordinary life. His body is quite special; he can't learn Breathing Technique. That's why I opposed him joining the Demon Slayer Corps. After all, if he can't use Breathing Technique, fighting demons is undoubtedly suicidal…"
"But his personality is very stubborn. Even though he couldn't use Breathing Technique, he still joined the Demon Slayer Corps. So, when he learned about the other cultivation system you brought—Ninjutsu and Chakra—he wanted to become stronger through other means…"
"I have a hot temper, and not many people like me. But I heard them say that you prefer an exchange of equal value, so…"
Sanemi Shinazugawa looked up at Uchiha Nagi, "If you want to learn Wind Breathing, I can help you avoid many detours…"
Uchiha Nagi had remained silent, waiting for him to finish, a slight smile playing on his lips, "Although you look like a gangster, you're a good older brother…"
Genya Shinazugawa, who had once been defeated by Uchiha Nagi's genjutsu due to underestimating him, rarely blushed.
"Bastard, don't say things I don't understand! Are you agreeing or not? That day's match was my carelessness. If you're not satisfied, let's have another match."
"I agree…" As an older brother himself, why was Itachi so different from him…
"Damn it, damn it, Genya Shinazugawa, why are you so stupid? He's not related to you, so if you want to ask him to teach you, you have to be thick-skinned. Why did you run away?"
Genya Shinazugawa, who cared about his pride, punched the big tree repeatedly. As someone who couldn't learn Breathing Technique, killing demons was indeed more strenuous for him than for others.
But thanks to his genes, like his older brother, the Wind Pillar, he possessed a special physique.
That is, he could eat demons—
By eating demons, he could temporarily gain a demon's physique and abilities. It was thanks to this that he survived the Final Selection.
To compensate for his lack of Breathing Technique, he even used a gun as an aid, combined with the Blood Demon Art he temporarily acquired when eating demons, making him invincible.
Yes, there were guns in this world. Genya Shinazugawa had acquired a double-barreled shotgun that could hold six bullets, wielding a nichirin blade in one hand and the shotgun in the other.
"Hey, hey, don't be so dejected, I…" Zenitsu had just arrived and was interrupted before he could finish.
"Damn it, are you here to mock me? Huh?" Genya Shinazugawa grabbed Zenitsu's chest fiercely and pinned him against the big tree.
"Ugh~~ I can't breathe… pantpant."
"Hmph!" After releasing Zenitsu, Genya Shinazugawa turned and walked away.
After being released, Zenitsu rolled his eyes and gasped for air. This guy really had a terrible temper.
"I wasn't finished! I came to tell you that Nagi-aniki (Nagi, older brother) wants you to come train with us tomorrow morning…"
Huh?!
Genya Shinazugawa, who was halfway gone, suddenly stopped, turned around, and quickly ran back, grabbing Zenitsu's clothes again and asking excitedly,
"You're not lying to me, are you? You're telling the truth, right?"
"Ugh~ Let go, it's true, I can't breathe…"
Genya Shinazugawa let go of Zenitsu again. Zenitsu rolled his eyes; the other party's strength was too great… A faint, ant-like apology came, "Sorry—"
"Hmm, what did you say?" Zenitsu immediately realized that the other party was apologizing.
"It's nothing, don't worry about it…"
Before he could finish, Genya Shinazugawa had already left, without the slightest hesitation. Zenitsu scratched his head.
"What a strange person…"
In the sunlit forest, Genya Shinazugawa's figure ran swiftly. Zenitsu's ears detected a sense of joy from him.
— — — —
The next morning, a new figure joined the daily training. It was Genya Shinazugawa, Zenitsu, and Xiao Zhuzhu Inosuke (Little Piggy Inosuke), making three people in total since Tanjiro hadn't returned yet.
Uchiha Nagi sighed, no matter where you are, only the thick-skinned get to eat. Genya was thin-skinned and cared about his pride. In fact, if he had dared to stay yesterday, Uchiha Nagi wouldn't have driven him away, because driving away one sheep or three sheep was the same effort.
Uchiha Nagi was very curious about Genya Shinazugawa's physique, which allowed him to eat demons and temporarily gain their energy and Blood Demon Art. Could it be another Shin?
Shin was one of Orochimaru's subordinates, who fanatically craved the Sharingan and had a very special body that could fuse bloodline limits without rejection. Danzo's arm was fused with the First Hokage's cells and the Sharingan using Shin's cells as a medium. He later died in Boruto: Naruto Next Generations… However, Genya Shinazugawa's physique was clearly even more special. Regardless, Uchiha Nagi planned to study it.
"Same old, ugh~ Tanjiro isn't here today, so it'll be the three of you. Here are two bells. The three of you will compete with my Shadow Clone to snatch them. Whoever gets a bell gets to eat." Uchiha Nagi mischievously took out two bells.
Then he created a Shadow Clone to train with them, while his main body cultivated by himself.
"Huh? But there are only two bells. What about the person who doesn't get one?" Zenitsu asked curiously.
"If you don't get one, you naturally don't eat. Special training naturally needs a bit of a prize. So, get ready, you can also discuss tactics. Ugh~ There's still half an hour, it starts at exactly nine o'clock—" Uchiha Nagi said, checking the time.
This was a problem Uchiha Nagi had discovered: because they hadn't experienced battles on the scale of the Ninja Wars, their combat literacy had always been low. Whether it was one person or three, their coordination was entirely coincidental, and they never had squad tactics or synergy.
However, good squad coordination and tactics sometimes lead to excellent results, especially against single demons.
[PS: Although the Wind Pillar is a bit crazy, he is actually a good older brother, and to be fair, he doesn't explain even when misunderstood by his younger brother.]
