A Hero's Assassination Academia

.......

"Us, duh." Irina said in a bored tone.

"B****-sensei?" The five exclaimed. 

"How vulgar." Aizawa spoke.

"That is not the right way to talk to your teachers! You should address them properly with their correct names! You cannot call them such rude things." Iida did his weird choppy thing in the air, trying to lecture people who would probably never listen to them.

"Don't worry, the feeling's mutual. You brats already know our abilities, so you better give it your all!" 

'Okay, I see where the rudeness comes from.' All the students and teachers thought.

"But dang, she's hot." Denki whispered.

"Yo, do you guys get restraints or something like the other students?" Karma asked.

"Hell no! You brats think you can have it easy?" Irina rolled her eyes. "You're lucky that your only criteria to win is to capture us with those white strings."

The field was set up, and all the combatants took their positions. They had created it into a hide-and-seek style, and the teachers would be the ones looking for them.

"Found you." Karasuma threw a punch at Kayano, who narrowly dodged it, but failed to notice a bullet coming her way.

In the nick of time, she used her quirk to create a cushion and stop the bullet. Karasuma looked around the area, before noticing something very odd. 

'All the students are gathered here? I can't find them though...no way...'

"IRINA, WATCH OUT!"

"Huh?" Karma swung down from the ceiling, holding on to a pipe and kicking the blonde-haired teacher in the face. 

"Let me teach you a lesson, B****- sensei~" Karma smirked before jumping down and engaging in close combat, and that was not Irina's strong point, "Analyze your opponents rather than believing in your own abilities, quoted from the octopus head himself."

Karma threw another fist, then gave her a round kick. She fell to the floor losing her balance. 

"Wow, thanks." She sweetly spoke the last word while holding her hands in gun-like manner, and Itona appeared from his hiding place behind the rocks to pull Karma back.

Right, B**** - sensei's quirk was to summon some heavy artillery using the code word "thanks" and holding her hand in a certain way. However, she had to be injured by herself, which happened when she lost her balance, not to mention how her quirk depended on her mentality, so if she was in a frantic state, it wouldn't be that effective, so you can think of it more like a burst ability rather than a long-time one.

"It's always a pain to fight even if you know it's coming." Karma grumbled as he dodged the swarm of bullets coming at him. 

Nagisa rolled out of his hiding spot and lunged at Karasuma, and Rio dropped down from the ceiling to kick him from the back. Kayano quickly healed Karma while Itona fought back. 

"I'm hungry. Can't we just ditch exams and get ramen?" Itona mumbled.

"Tonkotsu or shoyu?" Karma asked as he stood up.

"Miso or curry." 

"Personally I'm a shio person, but okay."

"Why the hell are you guys discussing ramen broths in the middle of a fight!?" Irina barked.

"If I win, Karasuma's going to buy me ramen after school." Itona declared. 

"Do I get a say in that?" Karasuma asked, though he already knew the answer.

"No." Itona flicked his hands, and a series of strings swirled around Karasuma, while he was trying to get rid of them, Karma grabbed a fire spirit from his quirk and shoved it down the black-haired teacher's collar. Pressing two fingers against it, it exploded.

Flames erupted, sealing themselves on the back of Karasuma. "This is only going to weaken him for a certain amount of time! We need to defeat him quickly." Karma ordered.

By instinct, the girls took B**** - sensei, and the rest headed for Karasuma. Karasuma's ability, hunter, was able to numb the burning pain in his back, but it wasn't enough to fend off all his students. 

'Itona most likely has the white string, considering his quirk. Karma's probably done as much damage as he can with his quirk, so I can expect his and Nagisa's attacks to all be physical. I can deal with that.'

"What are you spacing out for?" Itona flicked several strings towards Karasuma, but they weren't able to hit. Nagisa stabbed a knife down, but it didn't hit either.

Karasuma jumped a distance and loaded an arrow burning with fire, and shot it through the air while gaining size, slamming Nagisa in the arm. If it wasn't for the scales he had for defense, his bones would be shattered.

'Nagisa's weak in physical constitute. Its his assassination that's frightening. Him jumping away to find a good place to hide and plan was a good idea. Itona's launching strings in random directions, so it's safe to say he's setting up some sort of trap.'

"Don't forget about me, teach." As if he could read his mind, Karma punched Karasuma in the gut out of nowhere, with another fire spirit in his hand. He burned it once again, despite looking like he was running out of energy.

"I have three more of these. Well, might as well use them." He dropped the other three on the floor, and stomped on them. A winding path of flames opened up, burning on the strings Itona had created. 

Itona tugged on them, which closed in on the teacher, grazing his arms as he did his best to ignore the pain and find a way out. 

'Below.'

He jumped up and saw a snake hissing at his feet, and above him, Nagisa holding white string connected to the snake below. In a split second, he found himself tied up by it. Kayano and Rio had finished their things too.

"Not bad, you guys really have gotten stronger." Karasuma closed his eyes and nodded, accepting defeat.

Meanwhile, Class 1-A was watching with either scared looks on their faces of "I don't care" ones. But the teachers were definitely having grim attitudes at how brutal they were.

"How can they just do that..." Midnight muttered.

"Well, it's a good example of how even the weakest-looking quirks can be quite strong." Aizawa said.

Author here! Here's a fun fact. Irina's quirk is a quirk of irony. Her last name, Jelavic, can roughly be translated to "Thanks", and her first name means "peace". But her quirk is literally artillery weapons, which contrasts to peace.
