Midoriya's hand took on a claw shape in his panic as the needles rocketed towards him. Unlike what usually happened in these situations, for once the world didn't slow or give him time to react and it really put into perspective how much the greenette relied on that passive power.
Because the needles had been inches away from his body before he turned into smoke and shadows, dropping to the ground.
'Kill. Destroy. Maim. Torture.'
He let out a horrible angry shriek as he shook his mist like head, trying to clear the thoughts while the demon looked at him shocked before grimacing.
"Well, that's absolutely horrifying." He commented disturbed, only fuelling Midoriya's curiosity over what made the form so scary. He didn't have time to dwell on that though as he returned back to normal and bolted forward, throwing Far Reach up onto the platform to reach his opponent.
It went up, ready to land and then…. It went straight through and he was suddenly catapulted towards the wall. "What the?!"
Kiyoshi, seeming to have anticipated this turn of events grinned as his prey got closer and jerked forward, grabbing the greenette by the throat and slowly beginning to crush his windpipe.
"I wasn't sure what to think when you of all people showed up here. God's little pet, ready to kill us all but you're nothing like what I expected." He laughed, grip getting tighter. The marked teen clawed at his throat, air leaving him and face going blue, he couldn't concentrate on pulling out any of his powers. "But this? This is pathetic. I don't know why I was ever scared of you. Goodnight, Izuku."
As he said that, the demon's other hand suddenly formed a ball of dark purple energy, which crackled in his hand. He then threw his arm forward, intending to shove it right into his opponents face as Midoriya saw black spots in his vision.
Midoriya stopped fighting the choking however, recalling what Nana had said earlier and reaching for his pocket. His body crackled with his own green energy and his sword unfolded and came out fast, slicing straight through the demon's hand.
"AHH!" The Demon let out a horrific pained yell, letting go of the greenette and stumbling back while Izuku gasped for breathe. Green lightning bounced off Midoriya and suddenly the teen grinned, rubbing his pained throat.
"Almost forgot I can use One for All now." He laughed hoarsely, pointing his sword forward. On the floor the monsters hand twitched before dying, completely separated from its body. 'Ha! Thank you, Hatsume!' "Come on doc, let's see you patch that one up."
Midoriya grinned for a moment, but it immediately faltered when all too suddenly the demon's body started wavering back and forth, fading before a pair of arms wrapped around him from behind, throwing him into an invisible roof and causing him to let out a yelp of pain.
He hit the floor with a painful thud, his sword skidding away from his reach and he was pinned onto the ground by the demon. 'I'm sorry, do ALL demon's have some kind of damn teleportation?! Why am I being cheated of that one.'
"You made a mistake coming here." Kiyoshi said with a grin, lifting his other hand and forming an energy ball once more.
"Tensei… and Tenya… have suffered enough!" the Marked teen growled. "I won't let you do anything to them while I still live."
"Then I guess it's time to die, brat." The fake doctor laughed, pushing the ball of energy once more towards the greenette, but this time the marked teen's reflexes did kick in.
The world slowed, and he saw the ball coming. He took a quick breathe and focused One for All AND his magic into his hand, breaking free of the hold just barely and grabbing at the demon's wrist, causing them both to twist around so that Midoriya was now on top, grabbing his sword as they rolled.
All too suddenly the darkness faded and the world literally shimmered into view, but they were no longer in the hospital room but on the roof. The marked teen quickly backed off from his opponent and looked around surprised.
"Dammit, your messing up my powers." The demon growled quietly, before throwing the energy ball. The world slowed again and Midoriya was instantly back to being focused.
'One for All, full cowling!'
His right hand sliced his sword forward and his left hand formed Far Lance, which together sliced the ball of energy into four different pieces that all sailed past the greenette landing harmlessly in the ground.
"Got any more tricks?" Midoriya taunted, remembering the USJ demon had only a few things he'd been able to do. Unfortunately, it turned out that wasn't a universal standard as all to suddenly the distance of the city was drained into pitch black and a rumbling noise drew his attention.
Turning behind him, his face paled as a version of Kiyoshi taller than the hospital towered over him with a sadistic grin.
"Oh come on." Midoriya complained, before dashing out the way of a massive hand that tried to crush him. Then an energy ball hit him square in the back and he let out a pained yelp as he was thrown into the railings. However, as he flew he went straight through the giants hands. 'What the-OW!'
"My god you're a pest." Kiyoshi muttered, stretching. "It's going to be so satisfying when I have your guts strung up in front of this hospital."
"Surprised you know anything about guts, considering you don't have any." Mdioriya groaned, looking at the hand he'd gone through. As Kiyoshi stared him down, the greenette pulled out one of the needles and launched it at the hand before smiling when it did the same. "And now, now I know you're real power. That's why my body didn't react to those needles. It's just an illusion. You're nothing more than a trickster."
The demon scowled, clearly irriated the teen had figured out his secret. Then, he smirked as hundreds of fake Kiyoshi's surrounded them, as he disappeared in the crowd.
"Ingenium's death won't be an illusion though, good luck catching me in time." He laughed, and Midorya grimaced as he realized if the demon got away now, there was no way he could catch up in time even with One for All. His mark flared to life and the world drowned in sepia tones, showing in green Kiysohi near the centre.
The boy wasted no time launching forward, grabbing the villain but before he could even react a fist hit him square in the jaw as the world came back to normal. He fell to the ground with a pained yelp and Kiyoshi grabbed him by the shirt, pulling him up and delivering a strike to the stomach.
The teen tried to grab the next strike but suddenly he was dropped down and kicked in the teeth before a kick to the face twisted his entire body around. The villain dropped down and seared and energy ball right into the marked teen's back, causing him to let out a cry of pain before finally he was lifted up one more time.
"You really aren't all you were cracked up to be." Kiyoshi said disappointed before throwing the stunned greenette over the railing. Midoriya only regained his awareness once he already began plummeting, seeing the demon shimmer away.
Now he was falling, with no one to reach Tensei in time to save him and if he didn't act fast, even a way to save himself.
For the last time, the world slowed again once more, giving him time to think. He looked towards the windows, realizing he was falling down the side Iida's brother's room was on.
One more floor and…
There! He could see the Demon standing in the room, energy ball in hand. Wasting no time his hand shot forward and Far Reach shattered through the glass.
He was launched through the air but there was no way he could land safely in this situation. The glass wasn't even properly broken so he was going to be cut to pieces, not to mention the impact.
Thinking fast, his mark glowed blue and his body turned to smoke yet again as he landed on the floor of the room, Kiyoshi looking towards him in surprise. The doctor didn't even have time to react before Midoriya finally lost control.
'Kill, murder, torture, hurt, die die die!'
The shadowy form moved forward at terrifying speeds, swiping the demons legs out from under him and pouring atop him, forcibly tearing one of his legs off.
"AHH! NOO, NO STOP! AHH! STOP THIS AGGGHHHHHHH!"
Midoriya didn't stop. His form poured inside the new wound, causing the body to bloat until the shadows were pouring out the demons mouth and ears and his screams could no longer be heard, squashed by the entity tearing him apart inside, crushing everything inside him.
Tearing his very core of magic apart before finally his head burst, The shadow creature pouring out and turning back to normal as the demon literally imploded.
Midoriya stood over his work, growling in anger before finally his senses returned and he realized what he'd done. His throat went dry and his eyes went wide.
Some shouting came from outside, but by the time anyone showed up to the room the greenette was gone, crawling through the vents back to his room.
He never stopped feeling like he was going to be sick, not even leaving the bathroom once he arrived back in his room.
