A Rush Of Blood (BNHA/MHA OC)

Consequence

Hisoka and Bakugo stood outside, both in their gym uniforms.

"Okay, Blood Bitch. Release an explosion." Bakugo ordered.

Hisoka rolled her eyes. That was certainly easy enough. She aimed her arm straight forward, letting out a pained yelp when she released a small one from her palm.

"The fuck are you doing?!" Bakugo snapped.

"What you fucking asked!" Hisoka retorted.

Bakugo growled, saying "Not like that! You'll tear your fucking arm up!"

Bakugo stomped forward, pushing her to the side.

"Explosions aren't like a normal power. They require fucking finesse. Firing them off like that's gonna tear your fucking arms apart!" He scolded.

He then aimed his palms forward in front of him, letting a few pops off them.

"Focus on my stance. First of all, explosions require you to have a strong GZP."

"What the fuck is GZP?" Hisoka questioned.

Bakugo blinked, before saying "Oh, right. That's what I call it.... Basically, GZP stands for 'ground zero position'. Kinda like how Deku needs to not use too much strength or he shatters his fucking bones, you need to have a decent stance."

Bakugo stretched, before aiming his palms in front of him once more.

"First, you need to keep your feet apart. Explosions have a lot of force, so the better your ground zero position, the better. I'd recommend keeping your feet at least two feet away from each other before initial detonation, or wider if you want to use larger explosions. Second, keep your arms from being too straight forward. The recoil on explosions can be intense."

Hisoka nodded, before asking "How come you know all this? About explosions, I mean."

He just raised an eyebrow, before saying "It's literally my quirk. Also, I studied my own quirk a ton in middle school." He then continued, saying "Back on topic, notice how my arms look when I fire explosions. Not often are my arms fully extended. There's at least a little bit of leeway or slack in them when I release, since the recoil can be brutal if you're not doing it correctly. Popped my shoulder out of place when I was ten like that."

Hisoka stood next to him, copying his movements.

"Third, and this has to be the most important: know your fucking limits! I can't tell you how easy it is to ruin your shit with this kind of power. I'd also recommend adding some specialized gloves, to muffle the detonation noises. I'm already damn near deaf as fuck, so I'm fine."

Hisoka whirled, saying "You're what?!"

Bakugo just shrugged, pointing to his ears. It was then that she noticed the orange hearing aids in them, her eyes widening slightly. How had she never noticed those before?!

"I can read lips pretty well, but the hearing aids make it easier. Besides, without them my hearing is pretty jacked.... Mr. Aizawa once asked me what the square root of something was. I thought he said 'square up'. You can probably guess how that went." Bakugo said, grinning. "Now then.... Let's go!"

"What?!"

Hisoka didn't get the chance to prepare herself before an explosion was flung at her. She dodged, her own blood crimson ones lighting up in her palms, firing at Bakugo (pathetically, might she add).

"What are you doing?!" She hissed.

"Ever heard of learning on the fly?!" Bakugo retorted. "There's no better way to learn your limits than by carrying out your actions! Stop whining and show me you actually listened!"

Hisoka grit her teeth. She stepped back, aiming a palm in front of her, releasing an explosion at Bakugo. He took the hit, scoffing as he shrugged it off. He then launched himself at her, pinning her to the ground.

"We're doing this every day until I see something worthy." He sneered.

Hisoka groaned.

.

Over the next week, after classes, Hisoka would train with Bakugo. He was a surprisingly good teacher when he needed to be....

Which, of course, is why when she encountered Monoma that evening, she was really not in the mood.

"Fuck out my way, Monoma." Hisoka growled.

"Awe! What's wrong? Still mad about what I said?" He mocked. "Come now, I'm sure mommy would be very-"

Monoma was knocked to the floor by an explosion from Hisoka's hand. She glared at him, scowling.

"Don't talk about my mother." She ground out, stepping back.

She could literally felt the blood in her hands start to boil as she glared at Monoma.... And then, of course, the boy tapped on Todoroki, and sent a wave of ice at her.

"Stupid 1A-"

Hisoka hurled an explosion, charging straight at Monoma. She tackled him into the nearest wall, Monoma pushing her off, punching her in the face. She heard her nose crack, stepping back as blood dripped from it onto the floor.... Wait.

Blood.

Blood that was currently explosive.

Around Monoma.

Monoma, who had copied Todoroki's quirk.

.... Oh fuck.

"Time to burn, Akagura!" Monoma yelled, flames lighting up on his arm.

"Monoma, wait-" She tried to warn him.

A scarlet explosion filled the room.

*Elsewhere....*

Aizawa felt the building rumble, him and the other teachers instantly rising to their feet.

"Was that Bakugo?" Yamada questioned.

"No. Not Bakugo. Too wide, and even he's not that reckless. Also, I know his explosions. These ones sounded different." Aizawa responded, grabbing his capture scarf.

The floor above them cracked, before the ceiling crumbled. In moments two students fell down, and Shouta Aizawa was aware of two things.

One: Hisoka was on top of Monoma, stepping on his back, one palm placed against his head as smoke wisped from it, the other sparking dangerously next to her.

Two: Her blood was dripping from the ceiling they just fell through, and there was ice and scorch marks lying around.

"Do not," She panted, appearing out of breath. "Leave flames around the blood. Just.... Don't."

"Chihara." Aizawa growled out. "What. The fuck. Did you do?"

Hisoka opened and closed her mouth. She looked at the chaos, before just.... Shrugging.

"I was dealing with a rabies infested rat. Obviously, I won."
