Y/N lands on her four, panting heavily as her jaws are open. She leaves a crater in the ground when she lands and she feels no pain in her body. She looks at her body, seeing all the injuries that were inflicted on her are gone and there's no bleeding at all, but she has blood on her fur. That also must be part of Eri's Quirk too.

She sniffs the air, knowing that Chisaki smells different and she could hear the rumbles of him too. Y/N's body shakes and she stops using her Quirk and turns back into her human form again, Eri still holding onto Y/N's back as her body shakes. She lets out a shaky breath, her legs trembling and her body feels cold. So cold and she could hardly move her limbs. Y/N unties Mirio's cape from her body and she sets Eri down. Y/N crouches down, smiling at the little girl in front of her as Eri is clutching Mirio's cape in her hands. Eri is adorable and Y/N could see the sparkles emit from Eri's horn. She gives Eri a kind smile, tilting her head.

"Is that your power, Eri?" Y/N questioned, she sees the conflicted look on Eri's face.

Y/N lets out a gasp, clutching her body as she stumbles forward. She catches herself by putting her hand on the ground in front of her. She feels intense pain engulf her body and Eri backs up a little bit.

"What's happening?"

Eri looks at the girl in concern.

"It's like I'm being pulled from the inside."

"She has no control," Chisaki said, his voice disorientated.

Y/N grits her teeth, hearing the ground break and she quickly grabs Eri. She holds Eri in her arms as she runs away before the cement spikes could hurt her and Y/N grits her teeth, the two girls being safe from the cement spikes. Y/N narrows her eyes at Chisaki, seeing how he assembled his body into a tall, ugly, monster with multiple arms and only a torso.

"She may have activated it at a good time, but she doesn't know how to stop it," Chisaki said.

Y/N  could feel Eri grip her hero costume tighter.

"Isn't that right, Eri? She rewinds humans. That's who Eri is. Depending on how you use her, it might even be possible to turn a person back into a monkey. If you keep carrying her like that, you'll be annihilated. Everyone who touches her will be rewound into nothingness. That girl's Quirk is cursed. Hand her over. There's no way to stop her other than disassemble her. Unless you want to be annihilated, hand Eri over."

Y/N moves Eri to her back again, using Mirio's cape to tie her to keep her safe. She glares at Chisaki, unsure how this battle is going to progress, but she knows for sure that she's going to defeat him. That is the only way to stop him from getting to Eri.

"Never!" Y/N hissed, she clenches her hands into fists. "I'm never going to hand her over to you. She has such a kind and beautiful Quirk!"

At Y/N's words, tears swell in Eri's eyes as she looks at the teenager and the tears roll down her cheeks. Eri grips Y/N's shoulders tightly and Y/N uses her Quirk, transforming into the Indoraptor that matches the height of Overhaul's newly assembled body. She keeps her eyes focused on Overhaul.

"Neither you nor Eri knows the value of her power," Chisaki said, narrowing his eyes at Y/N.

"Quirks progress markedly when you develop them. By conducting countless experiments, I extracted Eri's power and succeeded in bringing it to its end point. As a result, it doesn't stop simply winding back the flesh. It winds back on a much greater scale. It rewinds the course of the species-- to its unmutated form. That's the kind of power Eri possesses."

Chisaki moves back, one of his many arms touching a building and disassembling it.

"The power to annihilate Quirk factors and turn humans back to normal! Enough power to destroy this world built upon Quirks--to destroy the natural order!"

Chisaki disassembles the cement spikes and there's dust filling the area as it's being whipped around by the air. Y/N simply glares at Overhaul, lowering her head as she pulls back the skin on her snout to show off them pearly, sharp teeths. She's not going to give up Eri and she's going to defeat Chisaki.

"That's Eri." Chisaki continued, bending that weird looking body. "You don't know Eri's value! A punk like you can't exploit an asset like her!"

Multiple cement tendrils are coming towards Y/N and Eri. Y/N puts all her weight into making the carter underneath her bigger and she jumps up, dodging the tendrils. Y/N pounces on Overhaul, slamming his body into the ground and encasing her jaws around his neck. She snaps her jaws down and dismembers the head from the body.

Unfortunately she jumps away before one of those many hands touches her. Y/N has a growl escape her throat, skidding to a stop as her and Chisaki fight on the streets. Y/N doesn't want to have any of the buildings around them to be damaged, so she'll try her best to avoid damaging them, but if Chisaki damages it, then it's all right because he did it.

"Eri's power has gotten stronger." Y/N groaned, feeling that pain of being pulled from the inside.

She falters a bit, her eyes focused on Chisaki as Eri's horn starts to glow in a pastel yellow color with sparkles coming out of it. Y/N stands tall on her back legs, they shake a little as she stands and she puts up her guard.

"Why won't anyone..." Chisaki growled, reassemble his body. "...look at the big picture?"

Y/N's eyes widen slightly, seeing the molds of flesh circle around Chisaki.

"What I'm going to tear down is this world-- its very framework! Your justice is small. You only see what's in front of you. It's mere sentimentalism. You hero pretenders..."

The molds of flesh on Chisaki's body assembles into bigger arms and legs on the man.

"Stay out of my way!"

Chisaki charges at Y/N and she lowers her body, charging towards him too. Once she's close enough, she clamps her chaws on his arm, but he reacts fast too. He placed his other hand on the ground, cement spikes plunging underneath Y/N's body and hitting her belly and arms. She lets out a grunt before she pulls off his arm that's stuck in her mouth.

She jumps away, her body burning from being pierced and she feels those wounds close. Eri's using her Quirk to help heal Y/N as she fights Chisaki and Y/N is grateful to the little girl. She would have definitely died or wouldn't be able to fight if she were to have those injuries still. Chisaki reconstructs his arm back, glaring at Y/N as she pants heavily. She turns to face him, lowering her body once more as she narrows her eyes at him.

"The man that tortured a little girl for his own ideal world without Quirks. She's just like me..." Y/N growled, Chisaki and her charging at each other. "I'm going to save her so she can live a normal life!"

Y/N and Chisaki are in front of each other and he pulls his arm back while the other one lands on the floor beneath them. She goes to pounce on Chisaki, but she's unable to as more sharp, cement tendrils pierce her body and she's unable to move. She glares at him as he pulls his fist back and she ignores the pain erupting from her body.

"How can I be a hero if I can't save her?!"

Chisaki thrusts his forwards her and she opens her jaws. She closes her jaws around his fist, a tooth breaking off from the force and she feels the back of her throat heat up. She breathes out the atomic flames, the flames hitting Chisaki's fist and his body. As the flames touch his body, he removes his arm and he steps back.

Y/N walks forward, breaking the cement tendrils that are poking her body break as she walks forward. Her body is slow and she opens her mouth, the flames building in the back of her throat and she aims the atomic flames at him. She keeps firing the flames at him as she watches the molds of skin be burned. She ceases from the fire and she walks over to the burnt flesh of Chisaki's reassembled body.

She pants heavily, blood dripping down her body and she clenches her jaw around the part where Chisaki is. She bites down on that part, making sure to not pierce her teeth through Chisaki's body because she doesn't want to kill him, even though she murdered Wu who clearly deserve it. She still wants to be a hero. And she pulls him out, slamming his body on the ground and stepping on him with her claws, scratching him slightly while wrapping her tail around his body tightly to make sure he doesn't move.

"I-I saw it," Nighteye said, Ochaco and Izuku with him as they see dust smoke from aftermath of Y/N's atomic flames fill the area.

There's only a glowing light that could be seen and from that they can see, it's moving.

"Chisaki succeeded in his escape and Y/N lost her life. That's.... the immutable future I saw."

Through the smoke, they see Y/N's human body fall to her knees, her breathing heavy as her eyes are closed. There's blood on her body and holes or grazes here and there on her body as her tail is slightly damaged. She's badly injured and Eri isn't on Y/N's back anymore. The little girl is walking towards Y/N with a concern look in her eyes as she holds Mirio's cape tightly.

"I... did not see... this future." Nighteye finished. 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Y/N's body hits the floor, lying on her stomach as her eyes are closed as there's blood exiting her body. Her body is still as Eri is walking over to Y/N's body that's on the floor. Eri drops to her knees, staring at the teenager's body in front of her with wide eyes as the pastel yellow glow and sparkles are emitting through her horn.

Ochaco goes over to Chisaki and quickly restrains him as Ryuko and the others like Tsu, Aizawa, Blue, Owen, Anjali, Tamaki, and Mirio with her are catching a ride on the dragon hero as she climbs out of the hole in the ground. Izuku limps his way over to Y/N and Eri, desperately trying to get to those two as fast as he can. Anjali ran over to see if her mom is okay.

"Uravity, what's the situation?" Ryuko questioned.

Ochaco looks to the dragon hero.

"Nighteye is in the back! We've called for residents in the vicinity to evacuate! Y/N's fighting Chisaki. But..." Ochaco trails off, looking where Y/N and Eri are.

"Something seems off!"

Eri places her hands on Y/N's back as she lowers her head and the pastel glow surrounds the two. Eri's Quirk is getting stronger as she wishes to stop her Quirk as she realizes that Y/N's body is trembling in pain. Eri could see the pain she's doing as her Quirk isn't helping with Y/N's wounds anymore.

Tears swell in Eri's eyes as she knows she can't stop her Quirk and she knows she's hurting Y/N too. Those tears roll down Eri's cheeks when she remembers Chisaki calling her Quirk a curse. Izuku and Anjali stops in their tracks, a few steps away from the girls as everyone watches.

Tsu feels Aizawa move his finger, the after effects of the yakuza's Quirk still taking a toll on Aizawa's body. Tsu gets the message and she lifts Aizawa's as his eyes are already focused on  and Eri. As Aizawa cancels out Eri's Quirk, the pastel yellow glow and sparkles are gone and more tears are rolling down Eri's cheeks.

Eri's head lands on [Name]'s back, the two girls knocked out and Midoriya and Anjali walks over to them. He lets out a sigh of relief when Eri's Quirk stops working, but he's concerned for Y/N. Her wounds still look serious despite Eri's Quirk and he falls to his knees, placing a hand on top of their heads. Anjali nudges the two girls with her snout, wanting them to stay awake to make sure they're okay.

"I-It's over..." Uraraka mumbled.

"Is it?" Tamaki asked, his eyes landing on Y/N.

"Kid..." Owen voiced in worry as Blue looks on with worry as well.

Ryuko deactivates her Quirk, turning back into a human.

"We have large numbers who are seriously injured! Call as many ambulances as you can get! Hurry! Go check to make sure we didn't miss any victims," Ryuko said, looking around at the lingering police officers. "The League of Villains may be nearby! Look for them!"

"Yes, ma'am!" 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"Sorry I couldn't get to you and L/N when it counted." Aizawa said.

Him and Izuku are walking in the hallway of the university hospital that those who were injured were transferred to. Izuku had finished getting checked up on by the doctor and Aizawa asked Midoriya to follow him. As for Blue, Owen, and Claire, they were in the waiting room of the hospital. Owen secretly had the suitcase with him as he does not want anyone to know about this creation from Wu as he did not trust them with it and would rather hand it to Y/N who can take responsibility.

"It's alright." Izuku said, walking behind Aizawa. "Anyway, how's everyone else?"

"Kirishima has bruises and lacerations on his whole body, but he'll live," Aizawa informed, slightly lifting his head. "Amajiki cracked a bone in his face, but none of his injuries will leave a scar. Fat Gum has broken bones in a few places, but he seems fine. Luckily, the blade that stabbed Rock Lock didn't hit any vital organs, so his wound won't develop into anything serious."

"I'm so glad..." Izuku said, letting out a sigh. "Um, what about Eri and Y/N? And where's Anjali?"

"Eri's still feverish and sleeping." Aizawa answered. "She's being quarantined right now. As for Y/N, she's currently sleeping as well. She has sustained multiple injuries."

Izuku's eyes widen, his mouth agape.

"The doctors said that her wounds are healing, but they're surprisingly fast thanks to Eri's Quirk. Or it could be the work of her Atomic Breath that dwell in her, but we don't know. For I know for sure, she'll wake up soon."

"Y/N's sleeping and Eri's quarantined..." Izuku trailed off, scrunching his eyebrows. "I can't go see Eri?"

"Apparently, it was decided based on the information we got from you about her," Aizawa said, still looking forward. "We couldn't even asked L/N about Eri because of the condition that L/N's in. She can't control her Quirk that rewinds people. If something activates it again, I'm the only one that can stop her."

They stand in front of an elevator.

"It seems like Eri continued to heal Y/N's existing injuries while she was on her, but Eri had fallen off her and didn't receives any injuries from that."

"From what I was able to see." Izuku said.

The doors open, Aizawa steps inside.

"There aren't many people who could do that. Even if there was someone who could, if that girl's Quirk became powerful enough to surpass that..."

"If you hadn't erased Eri's Quirk, I'm not sure what could have possibly happen to Y/N..." Izuku trailed off.

The doors to the elevator open again, Aizawa and Izuku walking out. Aizawa takes the lead again, leading Izuku somewhere in the hospital.

"Since it didn't work on the buildings or the ground, but only on people, training to teach her control isn't something we can approach lightly." Aizawa explained, his eyes forward. "Thinking about her emotional state on top of the unknowns, right now, it would be the most logical to keep her quarantined. For her sake, as well."

Aizawa stops walking and Midoriya stops himself before bumping into the man.

"In other words, we cannot depend on her Quirk."

"Huh?" Izuku questioned.

"All we can do is accept it." Aizawa stated.

The doors that they stopped in front of opened.

"He also justed arrived."

Izuku looks forward, seeing All Might in the room with Recovery Girl, Bubble Girl, and Centipeder. Although, there's another room within this room too. Just on the other side of the wall, if you look through the glass and into the dark room, Sir Nighteye is in there. There's multiple things that are in his opened wound as he's hooked to many things.

"All Might...!" Izuku gasped, stepping inside. "And Recovery Girl... Why?"

"I called them... because..." Bubble Girl started, tears swelling in her eyes.

She starts crying, covering her face with her hands.

"Sir was always talking about All Might..."

"Awata." Centipeder said, placing a hand on the girl's shoulder.

"There's nothing else that can be done..." Doctor explained.

Izuku's eyes are focused on the room that Nighteye is in.

"Honestly... it's mysterious how he's even still alive..."

"There's nothing I can do with my healing at this point..." Recovery Girl added.

Izuku has a fearful look in his eyes, processing the words that have been said. He couldn't believe what he's hearing, but he has no other choice to believe it and accept it. He just.... didn't think that he would get close to Nighteye and also witness someone dying during his hero work study too.

"Unfortunately, I don't think he will live to see tomorrow..." Doctor voiced.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Y/N suddenly woke up with a jolt and found herself in the white room with a monitor by her side as they made beeping sound as it showed her heart rate. She noticed that Anjali was sleeping by her side all curled up into a ball. She looked around as she realized that she's in the hospital and noticed her arms and legs are banaged up and is wearing a gown.

"Where's Eri?"

Anjali woke up, looking up to see her awake and jump into her and starts licking her face. Y/N laughed, trying to push her off.

"Anjali! Okay, okay! Yes, I'm alright! Come on, you know that doesn't wash off!"

Anjali eventually stop licking her and wag her tail in excitement and relief that she's alive.

"Where am I, Anjali? Where's everyone else?"

Anjali nodded to the door and that's when the doctor came in. Doctor was surprised to see her awake and healthy.

"Ah, you're awake. That's good."

"Hey, where am I? Where are the others?"

"They're fine. They will be recovered. You're in the hospital. Apparently, you've been out since your fight with Chisaki. Your wounds are bad, but they're somehow okay thanks to the girl's Quirk or yours."

"Eri? Is she okay? Can you tell me where she is?"

"I'm afraid you can't visit her. She's quarantined. She's fine and she's sleeping and had gotten a fever."

Y/N frowned to hear that.

"Will she ever wake up?"

"That we don't know. Now that you're awake, I believe you can move now normally. Just take things slow and be careful with your injuries."

Y/N nodded and listened to what the doctor told her and slowly got off of her bed. Anjali goes down to help her up as her feet was now on the ground.

"I have a question. I know everyone is okay, but what about Sir Nighteye?" Y/N asked, remembering seeing him injured very badly with a stab in the stomach.

Doctor frowned, looking down.

"I'm afraid... he won't make it."

Her eyes widen in shock and disbelief.

"No... Can you take me to him?"

"But with you need to recover."

"I know, but I just want to visit him."

Doctor reluctantly nodded and pointed to the direction Nighteye is in and Y/N didn't waste time going to the room along with Anjali. Once they made it to their destination, she noticed the door was ajar and saw Mirio in front as he looked like he was about to cry. She silently went behind him and listen to their conversation through the door.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

All Might goes into the room, standing next to Nighteye's bed. Nighteye has a mask covering his mouth, that being connected to a ventilator to help him breathe. All Might also didn't see this coming either and to think his old sidekick is now about to leave him. All Might takes in Nighteye's appearance, seeing how sickly pale that Nighteye is looking. It makes All Might's heart crack.

"Nighteye..." All Might mumbled.

Nighteye squints his eyes and then opens them, his yellow eyes looking dull as he looks to the Symbol of Peace.

"All Might... You finally feel like seeing me... on my deathbed...?"

"There's nothing I can say to that..." All Might said, looking down. "I've done terrible things to you..."

"Nighteye!" Izuku said, walking over to the bed and standing beside All Might. "Live! Do your best!"

"You're being... very respectful..." Nighteye said, gazing at Izuku as he speaks in a soft tone. A soft smile is on Nighteye's lips as he gazes at Midoriya. "I don't resent you at all." Nighteye looks away, closing his eyes. "Because all I wanted was for you to be happy... If you've decided to fight, then--"

"You should fight, too!" All Might suggested, his lips pulled into a thin line.

All Might's voice wavered as he spoke, looking down at his long time friend.

"Please let me atone for all I've done until now..."

"There's nothing to atone for...." Nighteye breathed, his breathing getting slower and softer. "I wanted to change the future where you were killed, so I kept looking for ways to change it... But it was to no avail... But today, Y/N showed me. I think... it might have to do with energy... A strong vision with no room for doubt. Energy that wished for a future. I'm sure it wasn't just Y/N. Midoriya and everyone else believed strongly in it and brought it together. So I thought it could be the result of that energy converging on Y/N... and being released... She's a good one."

Nighteye smiled and then his smile disappears.

"The future is uncertain-- My thinking has changed... That's enough for me... My only regret is..."

"Sir!" Mirio gasped, entering the room as Y/N and Anjali silently watch on.

He limps his way over to Nighteye's bed. Tears swell in Togata's eyes as he grips the hospital bed.

"You can't! Please live! You can't die!"

Nighteye scrunches his eyebrows.

"Mirio... You suffered so much because of me... If only... I had been..."

"It was...." Mirio said, his voice shaky as he cries. "...because you taught me that I was able to become strong! It was because you taught me that I'm living like this now! Please, teach me more!"

Tears stream down Mirio's face as he cries.

"Mirio, you'll..."

Nighteye's hand twitches, lifting it slowly and he places his hand on top of Mirio's cheek. Nighteye uses his Quirk, seeing Mirio's future and Mirio looks at him with wide eyes.

"...fine," Nighteye said, a smile on his face as he gazes at Mirio. "You'll become a finer hero than anyone else..."

Mirio's tears touch Nighteye's palm and it rolls down his arm. Izuku's even crying, gritting his teeth as he watches Nighteye and Mirio. Nighteye drops his hand from Mirio's cheek.

"This is the only future... that shouldn't be changed." Nighteye gives a kind and reassuring smile to Mirio. "So, smile..."

Mirio grits his teeth, lowering his head more. All Might is biting his lip, tears escaping his right eye as Izuku and Bubble Girl are crying openly. 

"Smile... A society without cheer and humor... will not have... a bright future..."

Nighteye noticed Y/N comes in with tears rolling down her cheeks as Anjali looks at him with sadden eyes. He smiled, knowing that Y/N will change the future as well as he could see her with all the dinosaurs by her side as she reunites them along with humans as they fought bravely against the villains. Nighteye's yellow eyes then turn completely dull. Mirio, Izuku, All Might, and Bubble Girl cry while Centipeder mourns quietly for Nighteye. The heart monitor lines goes straight completely, Nighteye's heart stopping and Nighteye has a smile plastered on his face as he passed away. Y/N silently cries, holding her face to stop her tears from coming down, but they went through as they drop to the ground.
