Burstfire

It was a week after the internships took place, Katsuki groaned as he felt his wrist ache in protest.

'Sometimes, I really wish I had another quirk.' He thought to himself, headed downstairs from his room.

He walked into the kitchen, noticing how quiet everything is.... A glow caught his eyes, seeing a piece of purple hair on the table. He started at it for a moment, a mix of fear, irritation.... And excitement, filling him.

.

"Alright brats, today we have an upperclassmen stepping in to join us.... Please welcome one of the top students of class 3A, Masami-"

Mr. Aizawa didn't get to finish as the new student walked in, Bakugo using his quirk to blast across the room in seconds. A violent combination of red and purple stared at him, gaze sharpening.

She reached out a hand, catching his hand as she aimed the explosion away from her. The two both grinned, Aizawa activating his quirk.

"-BAKUGO!"

She held out her hand, saying "It's cool, Mr. Cranky!"

Her hair was in a spiky pixie cut, purple in coloration. She had the same flawless skin as Katsuki, said boy grinning like a kid on Christmas day.

"As I was saying, Masami Bakugo. Bakugo, please introduce yourself." He said, Katsuki headed back to his seat.

"Hey everyone!" She said, waving at them all. "Grumpy over there calls me Masami-"

"Brat."

"-but you can call me by my hero name, Burstfire! Any questions?" Masami asked, several hands going up.

She pointed at Ashido, the girl saying "Are you related to Bakubabe?!"

She nodded saying "He's my cousin on his dad's side. It's one of the reasons our quirks are so similar!"

Midoriya raised his hand, and he immediately asked "What's your quirk?"

She smiled, saying "Toss me your pencil."

He threw is to her, the girl squeezing the pencil slightly. A dark purple slime-like substance came out of her hand,  going onto the pencil, she placed it on Midoriya's desk, Aizawa's eyes widening as it began to turn from purple a hot pink color.

"Wow! Does it only change color or does it-"

It turned red, Aizawa wrapping his capture scarf around him to pull Midoriya away from the oncoming explosion. The slime exploded, snapping the broccoli haired boy's desk in half, Katsuki bursting into laughter.

"HAHAHAHAHAHAHAHAHAHA! STUPID DEKU! OBVIOUSLY YOU'VE NEVER SEEN SLIME BOMB AT WORK!" He bellowed, laughter echoing out of him.

"Slime.... Bomb?" He slowly questioned.

"It's my quirk. My hands, chest, stomach, knees, and my head all produce a powerful explosive slime that will detonate over time! Those parts of my body also have a harder an denser skin, along with denser and harder bones, like my own bullet proof vest! I can't exactly fly like Katsuki, since my quirk isn't as built like his.

My quirk also makes my muscles more resistant to stress, making to only downside to my quirk the energy it uses up!"

Kirishima thought for a moment, before saying "I get it, so while Bakubro's quirk is meant for him to be more flexible and consistent, yours is more like making you a tank."

"Yup.... Which brings me to the favor I wanted to ask of Aizawa,"

.

A few minutes later, all the students of 1A were outside, all of them in their hero suits.
