"This time, I'm definitely going to cut it off!"
Tanjiro burst through the wind and soon arrived in front of Gyutaro. Gyutaro's face was fierce, and the blood he sprayed formed a flying blood sickle. Before he could even attack, Tanjiro swept it away.
This was his weakest moment! Inosuke was running away with Daki's crying head.
"Onii-chan! Think of something! I don't want to die!"
"Shut up!"
At this moment, it was as if the world paused for Tanjiro. The fragments in the air and the splashing blood seemed to still. He could see the panic and anxiety on Gyutaro's face, and clearly sensed the opening on his neck.
At this moment, the scar on Tanjiro's head seemed to burn fiercely, expanding into the shape of a raging fire.
"Ahhhhh!"
He roared, ferociously, swinging with all his might! The tip of his sword was also dyed crimson by the heat!
The paused time began to turn again, and a head flew up before falling heavily to the ground. Daki's head was also thrown onto the ground in the distance.
It was over.
"No!"
Gyutaro and Daki shrieked miserably.
"Watch out!"
Seiichi sandwiched the exhausted Tanjiro and the immobile Uzui between his left and right sides, retreating rapidly.
The two heads were covered in a bloody aura, and a huge sense of crisis covered everyone present. It was going to explode!
Zenitsu and Inosuke also quickly retreated when they saw the commotion.
"Boom!!"
The massive shockwave directly blew Inosuke and Zenitsu away.
"Holy crap!"
Seiichi realized his speed wasn't as fast as the shockwave, so he stomped his feet. The ground cracked inch by inch, and the floor was torn open, forming a temporary depression. He pulled the two of them down directly.
Though it was night, it seemed even more dazzling than daytime. A massive mushroom cloud rose into the sky, and the shockwave overturned all the houses in the passages. The sand and stones on the ground were carried faster than bullets, and smoke covered an entire corner of the Entertainment District.
The explosion slowly subsided, and the world finally fell silent.
Demon Slayer Corps Headquarters.
Ubuyashiki saw the letter brought by the messenger crow, his hands shaking, his heart pounding with excitement.
"This is a change that hasn't happened in thousands of years. The mission to kill Muzan Kibutsuji rests on our shoulders, cough cough! Good, good, you've killed Upper Moon Six together!"
He coughed, not caring about the blood flowing from the corner of his mouth.
"Inform all Demon Slayer Corps members of this good news."
His wife responded, helping Ubuyashiki lie back down.
The battlefield had already become a ruin. A Kakushi was rapidly searching through the ruins, occasionally exclaiming.
"What a truly devastating battle to behold!"
Suddenly, the Kakushi heard a sound of something breaking through the earth. He became alert and quickly moved in that direction. From within the thick ruins, a slender hand smashed through the overlying structures and stretched out.
Before the Kakushi could react, Tanjiro and Sound Hashira Uzui were thrown out. The Kakushi looked utterly confused.
"Sound Hashira!"
Seeing Sound Hashira Uzui, the Kakushi quickly went forward to examine his injuries. Uzui's face was covered in purple patterns, which was Gyutaro's poison.
Seiichi jumped out of the ruins. He was covered in dirt and dust, and his white clothes had been stained black by the grime.
The petite Nezuko, carrying Inosuke and Zenitsu on her back, hopped over. She came in front of Tanjiro, directly dropping them onto the ground. Then she proceeded to detoxify Tanjiro.
Although the process was roundabout, Nezuko had learned to use Blood Demon Art, a powerful flame that could burn a demon's power.
Tanjiro and Uzui, slowly waking up, looked incredibly excited. They had defeated Upper Moon Six, and no one had died. Uzui loudly talked about how flashy and festive it was, and the air was filled with a joyful atmosphere.
Uzui's three wives also rushed over. They had been preparing anti-poison medicine earlier, though it wasn't ultimately needed. Finally, the four of them embraced happily.
Tanjiro also cried while hugging Nezuko, loudly saying things like, "This is great! Everyone's alive!"
Zenitsu, slowly waking up, looked with disdain at the two pairs of people hugging. He then looked at Inosuke, who was also awake.
"There's no way I'd ever hug you!"
Zenitsu, embarrassed by the thought that had just flashed through his mind, shouted loudly.
"As expected, I still prefer happy endings."
Seiichi thought to himself, watching them make a ruckus.
"Seiichi-san, thank you! If it weren't for your help, we might all have... If possible, I have a request!"
Tanjiro, holding Nezuko, said to Seiichi.
"I hope Seiichi-san can join the Demon Slayer Corps. A swordsman as righteous and strong as you."
Tanjiro stumbled to his feet and bowed in request.
Seiichi helped him up and gently patted his shoulder.
"Are all the people in the Demon Slayer Corps like you?"
"I don't know, Seiichi-san, but as far as I know, everyone I've met is better than me!"
Tanjiro responded.
"Are there strong swordsmen in the Demon Slayer Corps?"
"Of course there are, Seiichi. There are many with strength like mine, and some even stronger than me."
Uzui, who was beside them, patted his wife's shoulder, no longer embracing her, and slowly stood up.
"I am the Sound Hashira of the Demon Slayer Corps, Uzui, and I sincerely invite Seiichi to join our Demon Slayer Corps. And here, on behalf of our Demon Slayer Corps, I express our gratitude for Seiichi-kun's help."
After speaking, Uzui bowed deeply. He knew that if it weren't for Seiichi, he would most likely have died. Battles change in an instant, and no one can say they are guaranteed to win.
Even their victory in the original story was full of various strokes of luck, but Seiichi's addition turned this battle into a guaranteed victory.
Compared to the original story, this was already much better.
No one was at their wit's end, Tanjiro also got sufficient training, the Sound Hashira did not lose his Hashira strength, and the Demon Slayer Corps even gained a new powerful fighter.
"Alright, alright, you're being so formal, it's making me uncomfortable. I accept."
Seiichi waved his hand. After all, this was one of his goals. There were many talented and extraordinary people in the Demon Slayer Corps. Moreover, he needed to absorb the experience of many master swordsmen, and in this world, there was no organization with more sword masters than the Demon Slayer Corps.
"That's great, Seiichi-san! I..."
Before he could finish speaking, Tanjiro collapsed. After being tense for so long, his body rebelled once he relaxed.
"Tanjiro! Tanjiro! Don't die!"
Zenitsu cried and wailed, snot and tears flowing, while hugging Tanjiro. Even little Nezuko had teary eyes.
"Tanjiro-sama is just overly exhausted."
The Kakushi felt Tanjiro's pulse.
"Without further delay, we will immediately return to the Demon Slayer Corps Headquarters. Firstly, for healing, and secondly, to discuss with the Master how to proceed."
Uzui made his statement, and everyone unanimously agreed with a show of hands.
"Am I finally going to the Demon Slayer Corps? Officially entering the core of this world's plot, my strength also needs to be further improved."
Seiichi thought, his gaze deep.
Next stop, Demon Slayer Corps Headquarters!
