Stain steps in!

"Oh no you don't!" Mirko cursed, turning quickly to pursue the Nomu, and looking as she ran for a roof to jump to so she could easily reach the Nomu without giving it time to evaded her in midair again. "Get back here with him! I'm not done tanning his hide!"

However, there was the sound of rope hitting the ground, and Iida and Todoroki turned to see Stain, up and running, having had one knife still on him they had missed. "Bakugo, look out!" Iida shouted as Bakugo sat up, seeing Stain was running right for him. Mirko froze, and was about to put off saving Izuku with Bakugo in more immediate, but Stain was closer to him, so reached him first. Instead of attacking though, he ran past him, but not before licking his cheek as he passed.

The Nomu suddenly froze up in midair, and Stain ran by Mirko, ducking under her kick as she still didn't know what he was doing, and leapt for the Nomu with impressive speed and distance, landing on its back, and stabbing it with the knife. In the same motion, he grabbed Izuku from it, and threw him away. Mirko immediately leapt for him and caught him. As the slain Nomu landed, Stain growled, "Everything I do... Is for a stronger society!" He ripped the knife free, and turned to Mirko. Then, he looked past her, and his face turned from angry to truly, utterly enraged.

"Well well, the Hero Killer," Endeavor remarked, stepping forward, having arrived moments ago, Ingenium flanking him. "It will certainly be a nice highlight of my career to bring you in..."

"You..." Stain growled, taking a shaky step forward, and then... The air suddenly seemed to thicken and turn red, as if Stain was somehow projecting his Killing Intent. Everyone was frozen. Even Mirko, no stranger to bloodlust herself, found herself taking a step back, though out of everyone, she was still prepared to attack him. "Endeavor! The biggest fake of them all! The worst taint on the name of Hero! I will reclaim that word! Come on! I'll take on all of you fakes! There is only one man I will allow to defeat me! All Might is worthy!"

Then, as abruptly as it had arrived, the feeling faded, and Stain stood still. He had... Passed out again from his injuries, but remained on his feet.

The aftermath was basically getting everyone to the hospital to be checked for injuries. Bakugo and Todoroki had the worst of it, Bakugo from the Nomu, and Todoroki from being a few knives shy from being legally describable as a pincushion from Stain. Mirko had sighed a bit at hearing about Bakugo's injuries, but decided that it would make something she had been meaning to talk to Izuku about easier. She'd been trying to think of a way to get Bakugo out of her hair for that, actually.

Iida had been scolded by Ingenium, but was let off easy due to the fact he had initially gone with extraction alone in mind, and had called the police on the way instead of having any ideas of fighting Stain. He only fought when it was clear that to do otherwise would mean leaving the others. The police arrived and decided that instead of punishing the four for breaking the law by using their Quirks against Stain without a proper license, or authorization from a Hero, they would give credit to Endeavor, Mirko and Ingenium for bringing Stain in, and cover up the four's involvement.

There was only one problem with that plan...
