What's wrong with this kid…
The wooden dragons shrouding the sky all shattered, falling in pieces and dissolving into nothingness.
Mitsuri's pink mouth dropped open in surprise, while Genya was still in a daze. He hadn't even reached there yet when Zohakuten suddenly shattered beyond recognition, even Hantengu couldn't make sense of it.
Nezuko, on the other hand, looked at Tanjiro with some concern. Tanjiro's current state was very strange. Red lotuses rotated clockwise in his eyes, and the crimson mark on his forehead became increasingly distinct.
Silently, a hand directly clapped onto Tanjiro's shoulder. In an instant, the lotuses in Tanjiro's eyes disappeared, the mark on his forehead turned to ash, and he collapsed onto the ground, utterly exhausted.
Turning his head, it was Seiichi.
"Seiichi-kun! That's great!"
Mitsuri rushed forward to hug him, but Seiichi held her back with one hand.
Nezuko was also very happy, rubbing her head against Seiichi's clothes.
"Tch!"
Genya also let out a sigh of relief, but being tsundere, he still stubbornly let out a "Tch."
"Seiichi-san, I felt so strange just now."
Tanjiro lay sprawled on the ground, gasping for air, feeling as if his lungs were about to explode.
Seiichi placed his hand on Tanjiro's chest, then infused a massive amount of energy into him. The gentle airflow entered Tanjiro's body, settling in his lungs and repairing the damage caused by his sudden burst of power.
"Didn't I say not to use it unless it's a matter of life or death?"
Seiichi still admonished him. After all, Tanjiro was the first swordsman he met in the Demon Slayer World, and if he died, Seiichi would be sad. Moreover, the main reason he found Tanjiro particularly pleasing was that Seiichi also had a younger sister, and he was a siscon. He deeply admired someone like Tanjiro, who would risk his life to protect his sister.
Indeed, the Crimson Lotus Breathing Style could truly be fatal. The scorching combustion would begin in the lungs, burning them completely. After that, various parts of the body would char, accompanied by spontaneous combustion, until the entire body was incinerated.
As for why Seiichi was so clear about this, it was because he had just perceived it from within Tanjiro's body. It must be said, the Transparent World was truly a top-tier medical tool.
Perhaps his physique wasn't strong enough. Could it be used without harm if his spirit reached 9 points?
Tanjiro didn't activate it for long, only for a blink of an eye, and didn't suffer much damage. After infusing some Void Breathing Style energy, he could continue fighting.
"But Muichiro…"
"Don't worry, he's fine."
Only then did everyone notice Muichiro clinging to Seiichi's back, struggling to greet everyone.
"I… I'm fine, I just can't fight anymore."
When Seiichi first arrived, he discovered Muichiro lying near death behind Akaza, so he went to retrieve him first, then healed him.
When!
Fine cold sweat seeped from Akaza's back.
"That's great! Waaah!"
Tanjiro immediately hugged Muichiro and cried, and Mitsuri also rushed over to cry with them, almost crushing Muichiro to meet his brother.
"What are you doing? The battle isn't over yet."
Seiichi rolled his eyes.
"Hehe, but with Seiichi-san here, I don't think there's anything that can't be solved."
Tanjiro smiled foolishly, then his expression turned serious. He stood up with his sword, and Mitsuri carefully placed Muichiro down, turning her gaze back to Akaza.
He came with Kokushibo. If this person appeared here, that means… no, impossible. Perhaps these two didn't encounter each other.
"You are Upper Moon Three, that merman in the pot is Upper Moon Five, the little person secretly observing behind that rock is Upper Moon Four, and the one with six eyes is Upper Moon One. So, Upper Moon Two didn't come?"
With every few words Seiichi uttered, Akaza's expression grew more and more grim.
This person met Gyokko and Kokushibo, but he doesn't seem injured. Could it be…
Daring not to think further, Akaza took a stance, his Blood Demon Art unfolding! The compass silently observed Seiichi's fighting spirit.
However, there was none!
Indeed, he possessed the ultimate realm. This is not good news. How to fight? How to fight?
"Akaza, retreat."
Muzan's voice echoed in Akaza's mind.
Is it a matter of whether I want to retreat or not now? It's a matter of whether I can retreat, Akaza thought silently.
Swish!
Akaza's pupils contracted. Unable to retreat in time, he could only change his leg stance, kneeling on his right leg, and with a huge bend, he dodged the horizontal slash.
So fast! Not on the same level as that blue brat!
"Destructive Kill—Final Form: Blue Silver Chaotic Afterglow!"
Akaza, half-kneeling, dared not be careless and directly unleashed his strongest move. Hundreds of projectiles erupted from his body, their supersonic speed indicating immense power.
Seiichi, who was in front of Akaza, had already disappeared before Akaza's muscles even moved.
It missed!
Without relaxing, Akaza pushed off with his legs, hopping backward like a frog, and in a few continuous leaps, he vanished into the forest.
"Leave this demon to me, Tanjiro. You go find Upper Moon Four."
Seiichi turned and made a sweeping slash, and a thick line instantly split the ground, extending far into the distance, ending precisely at Zohakuten, who was regenerating his flesh.
Zohakuten's barely humanoid bones and flesh were once again shattered by the invisible sword energy.
Zohakuten wanted to curse, but he had no mouth at the moment.
Although a little time was lost on Zohakuten, Seiichi still shot off in the direction Akaza had left.
Leaving Tanjiro and the others looking at each other.
Tanjiro closed his eyes, using his sense of smell to locate Hantengu.
Not here, not there, but over there!
Opening his eyes, Tanjiro told the others the direction. He first urged Nezuko to hurry back, as dawn was about to break.
The three of them, Tanjiro, Nezuko, and Genya, rapidly pursued Hantengu.
Meanwhile, Akaza was still sprinting. The distant sky was gradually turning a pale fish-belly white, and he had to leave as quickly as possible. The plague god behind him was still in pursuit, maintaining a consistent distance, neither too far nor too close.
Is he using me as a guide?
Seiichi hesitated. He could actually kill Akaza quickly. The combined power of Transparent World, Red Nichirin Sword, and Sun Breathing Style was something Muzan knew best. But it was the same old problem: what if Muzan hid again?
Seiichi was now certain that the strength he had displayed was not enough to make Muzan give up on Nezuko, who could withstand sunlight. This meant that he could still use information asymmetry to launch a sneak attack. Just one chance would be enough to completely deal with Muzan.
After much thought, Seiichi still gave up on killing Akaza.
Akaza was actually very strong, as could be seen from the previous battle. Three Demon Slayer Mark-bearing swordsmen plus two heavily armored tanks could do nothing against him. One must know that after activating the Demon Slayer Mark, a swordsman's strength would surge. The lineup of these five people could completely defeat more than half of the Demon Slayer Corps from before.
Seiichi stopped, watching Akaza disappear from his sight in the distance.
At the same time, on the other side.
