MHA/BNHA react to For The Want of A Nail by Clouds part 1

Iida(gulping): Uh oh.

"Mastermind." Izuku looked around and saw a pair of red eyes staring at him from the darkness.

Spinner(lighting up): There's Stain.

"Well, I should hope I'm recognizable by now," He said cockily, "I am pretty high profile."

Inko(shivering): He's Izuku and yet... he's not...

"You're the one who killed All Might."

Toga: Hang on wasn't Stain a big All Might fan?

Spinner(huffing): If you mean that he respected All Might as a true hero then yes. (realizing) Uh oh.

Izuku smiled behind his mask and threw his arms out to his sides, "With pride. What can I do for you?"

"You can die!" All of a sudden three knives shot at him from the darkness. He managed to dodge the first two, but the third grazed his cheekbone before clattering to the ground. His brain kicked into overdrive as he turned to look at his attacker.

Todoroki: He must be going after him because Mastermind killed All Might.

Midoriya(feeling sick): Don't remind me. I just hope Stain can kill the other me or something. Get it over with. (everyone slowly turned to look at Midoriya) I don't want anyone to die!

Hound Dog: Yourself included, Midoriya. The other you may be a villain but he shouldn't die if there's a chance for otherwise.

Tsukauchi(muttering): That thinking is going to cause a lot more deaths I can see it now.

His eyes widened when he saw Stain, the hero killer. He knew that Stain had been known to kill villains, but that was back in his vigilante days; now he mostly targeted heroes. Well, except for him, apparently.

Izuku quickly picked up the knife that had dropped and wiped off the blood as best he could. He didn't know how the hero killer's quirk worked exactly, just that it involved blood and paralysis, but the odds were that there was some sort of blood ingestion requirement for activation like most blood-related quirks. He pulled his mask up a little higher to cover the cut on his cheek.

Endeavor: That won't hold him for long.

"So, are you gonna tell me what I did to get on your hit list?" Izuku asked. Stain was known to be long-winded, so hopefully he'd monologue for long enough for Izuku to figure out a way to either kill Stain or run away.

(Spinner looked insulted)

"You killed All Might!" All of a sudden, Stain was right next to him, grazing his arm and licking the blade before Izuku could stop him. Izuku fell to the floor as his body gave out on him and he tried to calm his breathing. Stain's quirk had a time limit, Izuku knew that much. He swallowed and hoped his intel was correct about how much Stain liked monologuing.

"You kill heroes too, we're not so different, you and I!"

Shigaraki(scoffing): I tried that argument with him and it went horribly.

Kurogiri: We really messed up that meeting didn't we?

Toga: Hey we're still here anyway so I don't see how it matters.

"All Might was the one true hero among the scum. He was the only one worthy of the title hero. The heroes I killed were selfish beings pretending to do was was good for society when in reality they are only furthering their own ends. They needed to be weeded out for the good of society. The heroes I killed sent a message to the ones that remain that they need to improve or else fall victim to my blade."

"And you believe that All Might's death sends the wrong message?" Izuku tried to move his fingers to no avail.

"It sends the opposite message. Killing All Might was an act of senseless violence and for that, you must die. By killing All Might, you have not made hero society better, you have deprived it of it's crown jewel. There is nothing left worth keeping; all that's left is trash! Don't you understand what you have done?"
