About five minutes have passed of me dodging villains and helping civillains here and there, I stop out of exhaustion. I realize I used too much of my quirk to fly this fast this much, so I tried to think of a quicker way to find them as fast as I could. 

When I get an idea, I nearly hit myself in the head because of it. I pull out my phone and open my contacts to call Izuku until it all closes and is overtaken by an emergency alert from a random location from the hero app with Izuku's name on it, but no description. 

"Oh thank goodness." Relief falls over me. "He needs help," I put it away and recognize his location is only two streets down and in an alleyway from me. "but he's alive and close." I Immediately fly his way, and in seconds I look down from a roof and find Tenya and a Pro Hero on the ground, with Izuku and Todoroki ahead of the two. Izuku is simply standing stiff as his classmate blasts ice attacks to protect them. "What?" I stare in confusion as the villain goes on a rant about appreciating Izuku and wanting 'fake' heros to die, and out smarts Todoroki, getting closer.

When he gets too close for comfort and swings his swords down on Izuku, I wanted to scream, but it was stuck in my throat. I snap back to reality and jump over the edge and spike the pressure up in the air. 

I couldn't tell if my body was burning hot or freezing cold at the realization that my boyfriend and the others could die tonight, right in front of me. Time slowed. The flashes of our fun times together in class, the festival, the funny conversations over the phone, and then that perfect image of Izuku and I at the beach when we first met, smiling with his usual red blush and nervous smile while he twiddled his fingers together. It all cracked. Like glass. Then it felt like I snapped.

A scary new feeling came over my body, It was a whole other level above adrenaline. It was like cold snakes wrapped around every limb and muscle I had and slithered up my neck, over my head, and then stopped at my forehead and cheeks, as a hard shiver ran from my spine, throughout my body. I saw everything so clearly and new, and when everything started to move faster again, it hit me like a wave that I had full control over. I fell feet-first between the two and smashed my feet onto the swords between the two. The blades snapped at the contact and stabbed into the ground below from the force. I back-flipped mid air and kicked the villain far down the alley and landed on the ground. When I looked back Izuku was still stuck in his same position, but his eyes were shimmering in white and blue lights as he looked to me with wide eyes. 

"Are you all okay?" I asked looking over the four. The Pro nodded slightly. 

Todoroki sighed in relief. "I am now that help has arrived." 

"N-no..." Iida groaned weakly on the ground. "N-Not you too. Get out of here! You'll die!!" 

"Speak for yourself pres. you're the one on the ground." I notice a stab wound in his upper shoulder. 

"Izuku." I say. He jolts from his trance.

"-U-Uh! Yes!"

"Are you okay? You haven't moved."

"There's a reason for that." Todoroki answered.

"Yeah." His face got serious again. "He's Stain. He's the Infamous Hero Killer. Don't let him cut you and drink your blood. That's how his quirk works. We figured it must be a blood type kind of quirk. If he consumes some of your blood, you will be paralyzed- Look Out!!" I whip back and see him charging fast. Todoroki blasts ice in his direction, making Stain dodge, and creates an ice barrier just in time. 

"I DON'T HAVE TIME FOR LITTLE FAKE HEROS LIKE YOU!!" He roars from beyond the wall, and we see him jump high above it with his other swords in hand and shooting down over Todoroki, who stumbles back off of a loose piece of ice and falls. "NOW DIE!!"

I grab the broken pieces of his old swords protruding from the ground and rip them out, running forward and clashing all four blades at the same time, holding him off and blocking his path towards my friend. He pushed down on me more and brought his face closer to mine. 

"You got some nerve little girl." He growls. I giggle darkly as my insanity grows. He growls in disgust. "...You may be a real hero after all, coming to risk your body and soul for these fools, but you still have the eyes of a villain." He grunts as I push back with the broken blades harder. My giggles turn into a wild hearty laughter as I see the blades in my hands cutting deep into my skin, blood flowing fast down my gloved palms and exposed forearms. Painless from the adrenaline in my body.

(Narrators P.O.V)

As the two struggled in the fight of strength, that Stain was slowly winning back, Izuku and the others watched in complete awe as Y/n laughed in the villain's face hysterically.

"All this stuff about real and fake heros is getting really old now. How about I show you a new move I learned!?" She screams with a wide smile.

"GRAH!!!" Stain grows frustrated and pushes down with all his strength. His mouth wide open as drools down onto the girl and tries to lean down to her hands and lick the blood from her hands. "You Fucking Half Breed!"

The air around the girl glowed again. Just like how Izuku saw her when she arrived before he was almost killed, smooth lines of light quickly wrapped from her legs, around her arms, around her body and stopped like three jagged lightning bolts at her forehead, and cheeks. Her eyes glowed for a split second and glowed lighter than their original color. The lines disappeared and her hair and Stain's loose clothes started to flow as the air around them began to shake and vibrate. Then the air exploded, throwing Todoroki and Izuku back onto the ground near the others. 

"Y-You fuckin-g bitch!" They look to see Stain stumbling out from Todoroki's former Ice wall, beaten and battered with cuts and bruises all over his body. "Is that all you got?" 

Y/n was standing there, licking her own blood from her hands gleefully, as if it were ice cream. When she stopped, blood was around her mouth and chin, with that wide and sickening smile from before. "No, this is what I wanted to show you." She dropped her hands and closed her eyes and her face turned serious and hummed. "I'm gonna call this new move..." As she thought, Stain retrieved his last sword, and charged. 

Izuku's blood ran cold. "Y/N! NO!"

And Todoroki stumbled to get up. "L/N!"

She took in a sharp breath, and opened her eyes once more. "Compression." The Hero Killer stopped dead in his tracks. He growled out like a wild animal as he tried to move but was still stuck in place. 

Izuku watched, shocked when he saw she wasn't even moving a finger. She had figured out how to use the move Gran Torino taught her. He was slowly getting the movement back in his body, but continued to stay still.

"W-w-what the hell is this?!" He yells, spitting everywhere as he becomes more desperate to move.

"Don't like being paralyzed, do ya? But wait, there's more!" She giggled. "I call this move compression, because it's the action of being flattened, squeezed, or pressed together by pressure. But I would really like to put my heart into this." The air around him glowed slightly showing that it was starting to pulse in a familiar rhythm to everyone. A heart beat rhythm. The air was tightening more and more for every 'bum-bum' that echoed out from each pounding beat. "Get it?" She smiled. His entire being tightened inward as he yelled out. They all watched in horror as he was slowly tortured and played with, by the beat of her heart. There they floated in the air. Winds were blowing strongly through the alley, whipping debris and trash everywhere.

She was exhaling slowly as her laughter calmed down and her senses were quickly returning as she listened to Stain's pain. Everyone's ears began to pop from the growing area of the pressure. Izuku found he had control of his body when he lifted his hands to his ears. 

"Let's get out of here before the pressure crushes our skulls and we get crumpled by the walls!" Todoroki yells over the roaring winds and screams. They look and see the buildings on either side of them were beginning to crush into craters from the pressure. He grabs the Pro hero as Izuku lifts up Iida. They jog out and set the two on the street barrier when the green haired hero runs back. "What are you doing?!" Todoroki hollers, stopping him by the arm.

Izuku turns around tries to yank his arm from his grasp but fails. "I have to get Y/n! I'm not gonna leave her alone again!" 

"She's gonna be fine! She can do this by herself!" He argues, gripping his arm harder.

Izuku shakes his head angrily. "Why should she have to do everything alone? She always had been! Why when we have the chance to help her, do we expect her to do it all herself, all the time? You know what it's like to be alone, just like Y/n has been," His voice weakens as tears form in his eyes. "So please, she needs help." 

Todoroki growled, and finally let go. "Fine, I'll stay here with these two, you go help her. Just, be careful." Izuku nods with determination and runs back into the ally of screams and breaking stones.
