Slayers And Heroes

Long Live The Demon King

Two days had passed from the attack at the training camp. While the students were either recuperating in the hospital or staying home on recommendation, the heroes had been working tirelessly to find Ragdoll and the headquarters for the League of Villains. The Hashira had been advised to help, but again, they were told that unless the situation took a turn, they could not kill the Nomu.

During the two days, the Pro Hero Safety Commission started to fast track getting the Hashira Hero licenses. It was on the recommendation of the Wild Wild Pussycats and the UA staff. They had only just received their licenses when they finally received word that they found both the League of Villains's hideout as well as where the Nomu were created.

The news that the Hashira and Demon Slayer students were watching was focused on the warehouse the Nomu came from. The entire front of the building was destroyed, and all the Nomu were restrained. Ragdoll was found, but she didn't have her quirk anymore. Then, a powerful, evil presence was felt. The feed cut out briefly before it finally returned. A towering figure stood over the heroes, all of whom had fallen, with a mechanical mask of some form.

Then the League of Villains appeared on the scene, having arrived in some strange black goop. All Might arrived only seconds after and began fighting all of the villains. But before he could make headway, All For One forcefully had one of the villains, who appeared to be made of shadows, teleport all of the villains away. They could hear All Might after the villains had been teleported away.

"Looks like it's just you and me now, All For One," he said.

They began fighting hard. The more quirks that All For One used, the harder All Might fought. Until after All Might seemingly exhausted all of his strength, turning into a whithered man, he triumphed over All For One. He stood with his left arm raised in a fist of triumph. All For One softly began chuckling.

"Believe it or not, All Might, I was still holding back. I have yet to introduce my strongest underling. Come out and kill him, Muzan Kibutsuji," he said the first two sentences softly, but the last one loud.

Out of the shadows of a wall that hadn't fallen, Muzan began walking into the moonlight. All around Japan, all around the world, which was watching, everyone felt a chill run down their spines. Everyone could feel the power in him. They could feel his malice, his hatred, his pure evil essence. He sauntered to All Might and All For One, deliberately slowly. He was studying the hero. When he was finally close to All Might, he just stood six feet away.

"So, you are the strongest hero. I must admit, I had my hopes while you fought All For One. But now you are just a withered man. A once powerful human, now powerless," Muzan said.

"Enough of the monologue, Kibutsuji, turn him into a demon. Turn the former symbol of peace into a new symbol of hatred, evil, vill--" All For One said.

"Yet, for all the power you could possess, I see no reason to turn you into a demon. You lack what I need. You no longer have your power, One For All. I shall have to hunt for your protege," he paid All For One no heed.

"You forget who I am, and what is mine."

Black spikes shot from All For One's fingertips and impaled Muzan in multiple spots all at once. All Might jumped back, unwilling to back down no matter what. But before he could deal an additional blow to All For One, all of the spikes were shattered and fell to the ground out of Muzan's body. He looked down on All For one.

"I believe you are mistaken. You have forgotten about who I am. You took my title, I am simply going to take it back."

All For One extended a hand towards Muzan and blasted him with a mix of his explosion quirk and air cannon quirk. To the horror of everyone watching, it completely disintegrated the entire top left of Muzan's body, which was also pushed back from the force of it. All For One began trying to get up, but All Might immediately bore down on him again.
