"Hosu you say?" Sir Nighteye questioned.

Toki nodded, saying "I'm worried.... I think Tensei's little brother might try and go after the hero killer.... And um...."

"Bouran?"

Toki winced, saying "How did you know?"

Mirai sighed.

"Look.... There might be a way to contain Bouran. But you and her won't like it, especially since we don't know why she's going after Stain."

.

Feza received a text message on his phone, Hawks looking over at him.

"Everything alright?" The hero questioned.

Feza stared at the text, saying "I need to fly and help my friend out. Is that okay?"

Hawks shrugged, seeing Tokoyami struggle to keep up with them.

"Go ahead! You're fast enough to be there and back anyways!"

*A couple days later....*

Hosu was in absolute chaos. Nomu were out on the streets. And where was Tenya Iida, you might be wondering?

"You're just here for vengeance? Pathetic."

He was currently staring at the hero killer.

"I'm here for more than just vengeance.... I'm going to make you regret what you did to my brother, Ingenium!"

That's when he lurched forward, a burning pain in his abdomen. What was this?!

"Oh, how unfortunate.... Guess you really aren't able to handle my power."

A dark red substance covered his body, this hero suit becoming a dark black color. Stain watched as his engines appeared to warp into more jagged forms, his helmet rising to cover his head once more. His armour became a black with red spikes sticking out of it, and the mouth of his helmet warped, becoming a sharp and jagged maw.

"S- Stain.... Kill, STAIN!"

"You're rather foolish, Ingenium...." Stain muttered.

"I, AM NOT INGENIUM! I, AM CHAOS!!!!"

With that, the crazed student ran at Stain, sending a kick into his chest, red flames jetting from his engine calves. Stain used his sword to slow himself to a stop, throwing a few knives and daggers at the student. Before they connected, Iida was tackled to the side by a green blur.

"IIDA!" Midoriya screamed, trying to get him to focus.

When he looked back, Stain was gone.

"You.... You let him get away!" Tenya snarled.

Midoriya took a few steps back, saying "Hey, what's going on with you?! The Iida I know isn't like this! You need help!"

Tenya glared, hissing at him, saying "I don't need help! I'm the hero! You.... You're acting as of I'm the problem!"

"What?! No, that's not true at all! You're Tenya Iida! The class prez! You're not like this! We have to get that.... That thing off of you! It's making you act crazy!" Midoriya said, trying to get him to calm down.

For a moment, he seemed to be in pain, struggling. The weird darkness around his face receded.

"M.... Midoriya.... Help! I can't get it off!"

It covered his face again, and he spoke with more aggression and rage.

"No! I need this power! I will kill Stain, even if I have to tear through you!"

Izuku sighed, pulling his mask over his face from behind him. There was only one way this was going to work, and that was to beat the Tenya out of him.

"Come on, Iida! Fight this!"

With those words, he charged at Iida, the latter speeding out of the way of his attack. He sent a kick towards him, Midoriya barely having the time to raise his arm to block. He was flung back, getting launched out of the alleyway, straight into a a parked car. A trail of gasoline lit on fire, and when Iida stepped out, he visibly dealer from the heat of it.

"It doesn't like the heat?" Izuku mumbled in astonishment.

A wall of ice went up, the broccoli haired teen turning to stand next to Todoroki.

"Midoriya, what's going on?" He asked.

"Something's wrong with Iida, I think he's under the effects of some sort of quirk.... Oh! He doesn't like the heat!"

Todoroki thought for a moment, before saying "It makes sense.... Back during the Calvary Battles during the Sports Festival, Iida mentioned that his special move causes his engines to overheat and stall. So, if this quirk he's being influenced by is adapting to his body...."

"Then that means we don't have to hurt him seriously! We just have to burn it off of him, using your flames!" Midoriya said, determination in his voice.

A roar of rage caught their attention, Iida breaking through the ice.

"MIDORIYA!" Iida roared.

"Iida, it's us!" Todoroki shouted.

"Our name, is CHAOS!" The crazed teen responded.

He leapt at them, before getting pinned underneath someone's hold. When the smoke cleared, they were surprised to see Toki holding him down.

"Cure Maker!" She shouted.

She jumped off of him, Haso grabbing his head. Blue technical lines spread through his head, making him freeze in place.

"Override don't fail me now!"

Iida was slowly being overridden, the mysterious substance on him receding. With a sickening noise, it dripped off of him, leaving Tenya fatigued and tired. The disgusting pile of goo seemed to leap at him, the speedy teenager letting out a shriek.

A blast of flames incinerated the thing, Todoroki saying "You okay?!"

Iida nodded, leaning back to lie on the ground, saying "Thanks.... Wait! Stain! Native! That thing, it-"

Toki cut him off, saying "All three of you, you'll help Cure Maker find Stain. I need to find someone else...."

"Who?" Midoriya asked.

Toki scowled, saying "To go and find my dumbass girlfriend before she gets herself killed!"

*Meanwhile, across Hosu....*

Hoka, Daichi, Yukiko, and Tsuyoshi were in the process of removing civilians from a damaged building.

Mirko hopped over to them, saying "Is that everyone?!"

Hoka sighed, Aizawa running over to them, saying "I think so...."

Yukiko's ears twitched, the girl saying "Hold on, I hear someone!"

Daichi released a few palm sized drones that looked like small birds, letting them fly through the place.

"I see them! Four people, first floor!" Daichi announced to them.

Tsuyoshi groaned, using his quirk to try and hold the building stable, his dragon form pushing against the building.

"Hurry up, this thing is seriously unstable!" He shouted.

"Okay.... Virus, are you sure it's the second floor?" Aizawa questioned.

"Positive." The boy responded.

"Okay, here's what you'll-"

He couldn't finish as a blur of white fur ran into the building. Mirko screeched, not having expected her to actually run into the building.

"Blizzard, what are you doing?!" Aizawa demanded through his earpiece.

His response came in the form of a window on the second floor breaking open, Yukiko's form becoming visible.

She coughed, touching her earpiece, saying "Thunderzeke, catch!"

Tsuyoshi stared in horror.

"Are you kidding?! If I move, the building will collapse!"

"DO IT!"

He groaned, leaving his post to take the four civilians into his talons. The building began to crumble, Tsuyoshi and Yukiko's eyes meeting.

"RUN!"

Yukiko began running, leaping out of a window. Her relief was short lived when a large shadow went over her. Tsuyoshi cursed, handing the civilians off to Mirko and Eraserhead.

".... Fuck."

Tsuyoshi dove over her, the building coming down right on top of them.

*Back with team Toki....*

Stain grumbled in displeasure. The hero brat had gotten away.... Oh well. He'd at least been able to kill Native, so there was that.

Footsteps caught his attention, a voice saying "I finally found you, Stain."

He turned, looking to face Bouran, the girl in her Absolute Chaos mode, her skin a dark red.

"You.... Do I know you from somewhere? You appear.... Familiar."

Bouran scoffed.

"Tch. You're a fool, girl, just like that hero student." Stain stated.

".... You don't have any idea what you took from me...."

The girl glared at him. She would've charged at him, but a thick cage normally used for containing villain dropped on top of her, instead of bars, a thick bulletproof glass. Toki dropped down into the alleyway, a grim look on her face.

Feza sat on top of the cage, saying "Sorry Red, gotta do this to ya...."

Stain laughed at their interactions, saying "This is it? Step aside, I have no qualms with either of you.... Only the villain girl."

Toki scowled, saying "Bouran isn't a villain!"

Stain seemed to pause, taking the time to look at Bouran, then Toki, then back to Bouran.

".... Oh, this just got much more interesting."

Bouran glared, growling at his apparent realization.

"So you finally figured it out...."

Toki turned to Bouran, saying "Figure what out?"

".... Here's my reason for going after Stain, Toki."
