The Betrayed Beast (MHA x Black Clover x Demon Slayer)

Chapter Twelve: Horrifying Monster

Asta walked into the door to see who are the people looking for him since he heard his name being mentioned.

'That voice is unfamiliar. But for some reason, I think this has to do with me.' Asta thought.

"Of course they called you, dumbass." Leon said in his thought.

'I'm not a dumbass!' Asta yelled in him. He opens the door and as he opens it, he saw no one but only the dust scattering the area.

"Huh? Where are they?" Asta asked. Izuku and the others suddenly were found inside the dimensional fortress of Muzan who is already waiting above them.

"AH! Wh-Where are we?!" Zenitsu asked.

"All Might, prepare yourself!" Aizawa said.

"Mu... Muzan!!!" Tanjiro angrily roared as he saw Muzan already waiting at them.

"Oh? So you saw me then, Tanjiro Kamado. I guess I brought some unfamiliar faces here in my home. How about we'll talk first before we fight to the death?" Muzan asked.

"Everyone! Muzan is above that upside downstairs!" Tanjiro yelled as everyone looked above and sees Muzan standing in an upside-down manner.

"H-He's standing downwards! What's going on?!" Aizawa said.

"Who is he?!" Izuku asked.

"He's the master of all the demons we fought! The one who killed our family, Muzan Kibutsuji!" Nezuko replied as she prepared herself.

"Splendid. What a nice statement to introduce myself to the visitors. I surprisingly caught you all without even glancing at the sun, thanks to Nakime, my remaining Upper Moon!" Muzan said as Nakime can be seen sitting and strumming her Biwa.

"Everyone, run away from here! I know there is an escape route somewhere in here! Go!" All Might exclaimed.

"B-But All Might, we can't let you fight that man alone!" Kirishima said.

"I hate to say this but, that man is going to be an impossible one to defeat for the likes of you, All Might." Inosuke seriously said as he steps forward and prepares his sword.

"If I remember, boar-head, Douma maybe was your father since he and your mother laid together. And since Douma noticed that your mother will betray him, she threw you to a cliff for you to escape and she'll take the death that Douma will give to her. Isn't it amusing?" Muzan asked with a devilish grin.

"You... I don't know who is my mother or what really happened... But I'm going to kill you... Literally, KILL YOU!" Inosuke roared and now jumps into the obstacles to reach Muzan.

"That's... If you can catch me. Nakime!" Muzan orders Nakime and a door suddenly rose from nowhere and smashes Inosuke to the body.

"Inosuke!" Tanjiro yelled.

"I'll catch him!" Shoto said as he fired an ice glacier into Inosuke's location.

'Ice? He can create ice? I can use him if I can inject some of my blood in him.' Muzan thought.

"It seems that I'll be having a lot of victims for today! So let's start the show while I'm on the mood! And if you're thinking you can get out of here, that's if... You are still alive." Muzan hummed.

"All Might. This one is a demon. I can't use my Quirk against him, but I'll restrain him so that you can deliver some punches into him." Aizawa said.

"Yeah!" All Might said.

"Everyone, don't let your guard down! This man is more dangerous than I thought!" Izuku said.

"We got your back, Izuku!" Tanjiro said.
