Hid, behind a pillar, there was Sanemi, who had sutured his stomach wound. Goku is out there... Unfortunately, the door is locked... We have to hold on until he arrives...
Suddenly, on his right cheek, the mark appeared. Without hesitating, in the attempt to help Gyomei, Sanemi came out and attacked Kokushibo.
He has the mark too... it seems like all the modern Hashira have it... thought Kokushibo, dodging. Suddenly, from a blind spot, Gyomei's spiked flail arrived, but the demon managed to dodge anyway.
It's three against one... If we consider that Tokito and Genya are still here and could join at any moment, plus Goku-kun, out there... He's alone against the five most powerful Hashiras and a very powerful slayer like Genya... thought Rengoku, attacking Kokushibo from behind, but still not managing to hit him.
Back with Muichiro and Genya, the Mist Hashira gave the lock of Kokushibo's hair to Genya.
"Hey, Genya! You okay?" he asked.
Genya's body reattached with an incredible regenerative speed. My body reattached with incredible speed...
The boy heard a voice.
"Kokushibo... How many Hashiras did you defeat?"
That was Muzan's voice.
That's Muzan's voice... The more I become demonic, the more I'll be able to hear voices, even Muzan's one... What will happen to my body? wondered Genya.
I see... Maybe these three... Are the three strongest Hashiras... thought Kokushibo, while countering the blows of Sanemi, Gyomei, and Rengoku simultaneously. Especially the one with the spiked flail. Even though he's blind, he's capable of this... I really hope my nephew is at least as strong as him... his weapon is well built, the impact creates an echo that allows him to feel the spaces and movements around him. It's hard to believe, but that's it. So, first of all, I have to destroy the other two swords!
Kokushibo clashed his sword against Sanemi's and Rengoku's. Fortunately, Sanemi put enough force to smash Kokushibo's blade on the floor.
"Flame Breathing: Third Form -- Blazing Universe!" exclaimed Rengoku, creating a cut on Kokushibo's chest. I did it! I hit him!
"You're starting to piss me off..." said Kokushibo. "Moon Breathing: Fourteenth Form -- Catastrophe, Tenman Crescent Moon."
Before the three Hashiras could even notice, lots of small crescent moons cut their bodies. Gyomei fell on his knees, Rengoku was sent a few feet away, and Sanemi crumbled to the floor, and two of his fingers-the middle and the index fingers of the right hand-fell on the floor.
With a single blow... he neutralized us all... thought the Wind Hashira.
"Even if you're numerically superior, you wouldn't be able to kill a child," said Kokushibo. "Once I'm done with you, I'll find my nephew and kill him as well, so there will be one left in this world who can resist Muzan-sama..."
The situation is tragic... said Gyomei, trying to get up, but his body didn't respond: the wounds were hurting too much and were too many.
At this rate, we're gonna bleed to death... Tokito too, if he doesn't stop his bleeding... I'd never think I'd say this, but right now, we need Goku's help, thought Sanemi.
"Time to finish you off," said Kokushibo. "Moon Breathing: Seventh Form -- Mirror of Misfortune, Moonlit."
Lots of crescent moons appeared towards Sanemi's direction, but before the worst happened, Muichiro arrived and dragged Sanemi away.
"I'm not letting you die, Shinazugawa-san! You can still hold your sword with both hands!" he said.
Nearby, Genya was waiting for the perfect moment to strike. If that monster notices me, he'll cut me in half again... Aniki, I won't let you die... I can't fail...
After thinking about it for a while, Genya decided to do it. He extracted a piece of Kokushibo's previous blade and ate it.
Even if there are three of us, we can't even get close... thought Muichiro, who was barely dodging Kokushibo's crescent moons.
They have no choice but to attack me together. No wonder, after all. It's better for me, at least I can finish off all four of them at once, thought Kokushibo. "Moon Breathing: Fourteenth Form -- Catastrophe, Tenman Crescent Moon!"
Kokushibo released his most powerful attack once again. During the chaos of the attack, Muichiro managed to go behind Kokushibo and stab him with his red blade.
"Get out of the way, kid!" said Kokushibo, attacking Muichiro with his sword. The attack almost sliced him in half, but even if it didn't, Muichiro got sent several feet away.
"It's my moment!" exclaimed Rengoku, jumping alongside Gyomei. "Flame Breathing: Fifth Form -- Fire Tiger!"
Kokushibo jumped and dodged. Then, he cut the two Hashiras and sent them away.
Dammit... everyone's unable to fight anymore... thought Sanemi. But before the Wind Hashira could finish the phrase, Kokushibo knocked him unconscious with the grip of his katana.
"Everyone's knocked out..." muttered the Upper Rank.
"I won't let you hurt aniki!" exclaimed Genya, from behind, shooting with his gun. Kokushibo vanished and reappeared in front of Genya. Then, he sliced him in half, vertically.
"This time, you won't be able to reattach your body," said Kokushibo. Genya's two halves fell on the ground, but somehow, he was still alive.
"G... Genya..." muttered Muichiro, barely sitting up.
"Your turn, scum," said Kokushibo. In the blink of an eye, Kokushibo dashed forward and aimed at Muichiro's torso to slice him in half. But suddenly, something cut Kokushibo's blade. Or rather, someone did.
"Hey, Muichiro-kun, this isn't how a Hashira acts in front of an Upper Moon."
Muichiro turned his head to his right and saw what seemed an angel in that moment. Light blue haori with orange flames. Medium-length hair, a red katana - no, two red katanas in his hands. Muichiro could not believe it: Goku had finally arrived.
"Sorry if I'm late, but the door didn't want to open," he said, turning to face Muichiro. "Kyojuro... are you okay?"
"G-Goku-kun..." muttered Rengoku, slowly regaining his senses. Suddenly, inside the room, Giyuu and Shinobu arrived.
"Tomioka... Kocho..." muttered Muichiro.
"Shinobu-chan, take them away and leave the room," said Goku. "I'll fight Kokushibo alone."
"What? Alone? There were five of us, and we still didn't manage to even land a hit on him!" said Muichiro.
"You're forgetting I'm stronger than you all," said Goku.
Slowly, Gyomei regained his senses too. "Tsugikuni..."
"I'm sorry, Gyomei, but now I'm gonna show you you're not the strongest member of the Demon Slayer Corps anymore!" exclaimed the Sun Hashira, pointing at himself.
"I hope so, Tsugikuni," muttered the Stone Hashira. "I beg you, defeat that monster..."
"I will," said Goku. Suddenly, Kokushibo tried to attack Goku, but without even looking at him, Goku blocked with his sword. "Sorry, dear oji-san, but I'm not done talking."
He looked at Kokushibo and attacked him to force him to jump backwards.
"Shinobu-chan, Giyuu, and if you can move, Muichiro-kun, help the others leave the room. They need immediate cures," said Goku. Then he noticed Genya. "Bring Genya too. I think it's over for him at this point, but I don't want his corpse to be hurt."
"As you say, Goku-kun," said Shinobu.
"Oh, and for the record, I love having viewers," said Goku. "You can watch me fighting, so you'll notice how strong your savior is."
Shinobu blushed. Then, everyone left the room, and Goku and Kokushibo remained alone in the room.
