"MUZAAAAAAAAAAAAAAAAAAAN!" Screamed Goku, enraged, throwing at Muzan. "Too slow," said the Demon King, kicking Goku in the gut and sending him away. Then, Muzan dashed back, killing the demon slayers over there. "He's killing them all!" said Kiriya Ubuyashiki, Kagaya's son. "Why is only Tsugikuni here? Where are the other Hashiras"
"That's enough," said Muzan. "You're all useless. Tonight, I'll destroy every one of the demon slayers. Every one of them."
"Pull yourself together, Tsugikuni!" exclaimed Kiriya. Goku slowly got up, clutching his guts. "Destroy every one of us, you say?" he asked, "Don't make me laugh, we'll defeat you!"
Meanwhile, Obanai and Mitsuri were fighting Nakime, Upper Rank Four, when suddenly, they something.
"Muzan is back! The Hashiras have to regroup!" exclaimed a Kasugai crow. "Goku is alone against him, reach him!"
"Goku-kun is in danger! We have to hurry!" exclaimed Mitsuri. "But... We can't leave until we defeat this girl with biwa..." she then realized.
"Hold on, Goku!" said Obanai. "Shinazugawa's little brother is dead, but they helped Goku defeat Upper Rank One... Comparing to them, I only wasted time!" he thought.
Back with Goku...
"Sun Breathing: First Form -- Dance!" exclaimed the Sun Hashira, but Muzan dodged and kicked him away. Goku crushed through a wall and finished in another room. "Ouch..." he grunted, getting up and moving away the debris.
(He... He's the one who ruined my life... Because of him, I never knew my father... Because of him, Genya-kun, Tanjiro-kun, my friends... They all died because of him... Because of him, Nezuko-chan became a demon...) thought Goku. (I can't give up! I have to avenge them!)
"You're too insistent," said Muzan, reaching Goku in the room. "All you talk about is avenge your friends, that boy with earrings... I didn't directly kill them, you know?" he said. "Don't make me laugh! You sent the demon who killed them! Kokushibo was one of your subordinates, dumbass!" exclaimed Goku.
"Isn't it enough for you to still be alive?" asked Muzan. "No. That day, I had to die, not Tanjiro-kun..." said Goku, as his body trembled thinking again about the night Tanjiro died. "So no, being alive it's not enough for me! I have to kill you!"
"Why are you so mad at me? I don't recall doing something to you or your beloved ones on my own," said Muzan. "The reason is simple: Because of you, I never knew my father!" said Goku.
"He wanted to protect me from you, so he abandoned me and lived without me... He was the only one you were scared of, wasn't he?" explained Goku.
"Yes, you're right," said Muzan. "I was afraid of you father. But now, he's dead. You're his son, but you're not him!"
"I know..." said Goku. "But as his son... I have to honor his will and fight until the end!"
After finishing to speak, Goku made a small cut on his arm and drank his own blood, activating his demon form. "I guess this is how you defeated Akaza and Kokushibo..." muttered Muzan. Goku didn't reply.
(Even if I behead him, he won't die... I have to resist until everyone arrives and until the sun rises!) thought Goku, resoluted. (But first, we have to find a way to conduce him in an exposed place to sunlight...)
"Sun Breathing: Third Form -- Raging Sun!" exclaimed Goku, dashing towards Muzan and cutting his arm. However, it regenerated immediately. "Fourth Form -- Burning Bones, Summer Sun!" exclaimed Goku again, attacking once again. But then, Muzan's arms became longer and attacked Goku, provoking him a cut on the back. (His arms are too sharp! And he can even grow them longer!) thought the Sun Hashira. (I have to get past his attacks to get closer...)
Suddenly, without even knowing how, Goku sneaked away and reached Muzan. (I did it!) he thought. Muzan attacked again, but Goku dodged. (I dodged it!) he thought. But then, his eyepatch flew away, and his already missing eye got cut even more. (He hit me!) thought the boy, clutching his eye. "A demon who can't regenerate... You really are useless, hidden sun..." muttered Muzan. "S-shut up..." muttered Goku, coughing. (I have nothing to protect with, and not even an exit!) he thought, while dodging.
"Are you trying to stall until sunlight? It can't arrive here. How are you planning to do it?" asked Muzan. In that moment, A light bulb went off in Goku's brain. (I got it! I have to destroy the entire castle!) he thought. But then, he noticed something: Far away, Obanai and Mitsuri were lying senseless. "It seems like your friends were killed by the last Upper Moon remained," said Muzan. (No... It can't be... Obanai and Mitsuri too...?) thought Goku, incredoulous. "Who cares if I don't have my eye patch anymore? I lost my eye a long time ago!" he exclaimed, jumping away. But then, Muzan's arm hit him in the gut, and Goku smashed against a wall.
(It's over... Even if I use Transparent World, I can't see his attacks... And I'm completely alone... I'm done for...) thought the boy. (Well, at least, mine was a splendid life... I don't regret nothing... Tanjiro-kun, soon, I'll see you in Jannah...)
But then, just when Goku had accepted his faith, someone arrived.
"Stay away from Goku-kun!" it was Mitsuri, who had regained senses and swinged her sword to protect Goku. "Mitsuri-chan... You... You're alive..." muttered Goku.
"Are you crazy or what?" said another voice. Goku turned and saw Obanai. "Coming here alone with no one... Are you trying to die?" asked the Serpent Hashira. "Obanai, thank you..." muttered Goku.
(How are they alive? They should be dead!) thought Muzan. (What is Nakime doing...?)
Where Nakime was, Yushiro had arrived, and with one of his paper with eyes, he was manipulating her sight. "Do you want to know what's going on, Muzan?" I'm manipulating her sight!" he said. "You've committed the worst sins in this world, and now, we're gonna kick you outside this fucking castle!"
