My Hero Academia: Killer Quirk!!

"POWER!!"

Taking down the rest of the class 1A students, Mirio struck another impressive pose.

Not hearing anymore sounds of combat, Amajiki who was still facing the wall sighed. "Its over."

"Hehehe, not yet." Nejire giggled.

Now that his classmates had all been defeated, it was time for Aiden to step up to the plate.

"The demon of class 1A eh." Mirio smiled and got into a combat stance.

Ignoring all the stares he was receiving, Aiden activated his light step and executed the burst technique on the soles of his feet.

*BOOM!!*

Bursting forward at an astonishing speed, Aiden's figure vanished from sight and appeared in front of Mirio in an instant.

"He's fast!" Nejire covered her mouth in shock.

Covering his fist in astral energy, he struck forward at Mirio's unprotected face.

Smiling at his actions, Mirio was slightly disappointed that he was attacking him with the same tactics that his defeated classmates used. Activating his quirk, Aiden's astral covered fist passed through his face without dealing him any damage.

Seeing that he was unbalanced, he took the opportunity to attack the young hero.

Similar to what Mirio had just done, a sly smile emerged on Aiden's face when he saw Mirio's fist approaching him. Driving his astral energy into every part of his body, his figure transformed into numerous specks of purple lights.

Watching his fist hit nothing but air, a surprised expression appeared on Mirio's face.

"Woah! He copied Togata-san!!" Nejire cheered.

Deactivating his shift, Aiden's body appeared behind UA's number one. Thrusting his palm forward, he expected to execute a burst attack on Mirio's back. But to his surprise, it seemed like Mirio expected something like that to happen as his hand went right through his ċhėst.

Thinking that he had caught him off guard, Mirio didn't bother to turn around and instead used an un-hero like attack to retaliate. Driving his elbow backwards, he was somewhat astonished to find out that he had once again hit nothing but air.

Shifting again, Aiden continued trying to attack Mirio. Phasing through every attack, Mirio also tried to counter by launching an offense of his own. But to no one's surprise he kept failing due to Aiden's shifting.

---

After fighting like this for the next five minutes, everyone was in agreement that if this battle went on any longer then they would probably grow old in the gymnasium. Therefore they all agreed that the battle was a tie.

Even the lazy Aizawa was starting to get annoyed at the battle. Though it was unknown if it was because no one was getting hit or that Aiden was still undefeated. Just as he was about to call the match, Aiden did something that surprised everyone.

*BANG!!*

"WHAT!!" Everyone in the gymnasium gasped in union.

Looking down at his fist, Aiden clenched and un-clenched it. "I see." He smiled.

"Y-You hit me?" Mirio stuttered and touched his cheek. Even Amajiki, Mirio's biggest fan was shocked when he heard this. Unable believe what he was hearing, he turned away from the wall and turned to face Mirio and Aiden.

After watching Mirio's fight against his classmates, something about the entire event stuck out to Aiden. From his combat training back in Dark Star, one of the first things he learned was that before he entered a fight, he needed to get an understanding of his opponent's condition. Thanks to his brain being able to process information faster than normal people and his ability to sense other people by focusing on their breathing and heartbeats. He found out that whenever Mirio became intangible his breathing stopped.

While that knowledge was valuable, he had no plausible way to test his hypothesis without fighting Mirio himself. And after five minutes of up close observation, he determined that his hypothesis was indeed correct. Now that he had proven his hypothesis correct, all he had to do was force Mirio to breathe. With that thought in mind, he forced Mirio to enter his intangible state and used Catch these hands to let out a flurry of attacks while keeping out of range of his attacks. And just like he suspected, continuously forcing Mirio to enter his intangible state in short bursts resulted in him quickly becoming short of breath and unintentionally cancelling his quirk.

It was actually quite similar to what he did to the Nomu from the USJ.

[A/n: Both Mirio and the Nomu overused their quirks.]

Now that he figured out Mirio's weakness, winning was only a matter of time.

Using this tactic, Aiden kept forcing Mirio to use his quirk and hit him whenever he saw the opportunity.

"*Sigh* That's Aiden-san for you, making the impossible possible."

Hearing his words, the rest of the class also remembered that the one fighting was The Aiden Cross.

"Why were we even surprised? Compared to the herokiller this is nothing." Sero quipped.

"Yeah, I don't even know why I was shocked in the first place."

"This is Aiden we're talking about." Shoji added.

Nodding their heads, Amajiki and Nejire were dumbstruck by what they were hearing. To them, Mirio was a near unbeatable opponent. But the way the students of class 1A spoke about Aiden made it seem like him being able to hit Mirio was to be expected. In fact, they made it sound like it wasn't much of an achievement.

Feeling his breaths become shallow, the amount of damage his body was feeling increased by tenfold as Aiden relentlessly used Catch these hands to pummel him into the ground.

"MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA,MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA, MUDA."

[A/n: IS THAT A JOJO REFERENCE!!]

Adding burst to Catch these hands, Mirio wasn't able to endure and ended up flat on his back as the purple hands kept beating him down. It was bad to the point that all the air in his lungs had been forced out and no new air was going in.

Seeing that things were getting out of hand, Aizawa activated his quirk and called the match.

"...Aiden wins."
