    When (Y/N) and the rest of her classmates are fully awake in the common room, Aizawa suddenly enters with a stricken look on his face.

    "Everyone, (Y/N) has.." He trails off as he locks eyes with the number one hero, "..been here the whole time?"

    It's now that the class notices the cuts and bruises covering their homeroom teacher's body, each of them give him a very concerned stare.

    "Mr. Aizawa, I've been here the whole time..what has been going on?" (Y/N) asks.

    "There..there must be an imposter." He mutters in reply.

    (Y/N)'s and Shoto's faces immediately drop, "What?"

    "There's a girl out there, she looks exactly like you..but I don't think she has the kagune quirk or the manipulation one." Aizawa responds, "She's your imposter."

    "Those dreams..weren't just a figment of my imagination?" (Y/N) mutters, her eyes widening. "Everyone, you are to stay here, no matter what's going on outside. You got that?"

    Reluctantly, class 1-A all nod together.

    "The heroes and I will handle this." the hero continues, "My visions showed you all dying, and I am not letting that happen."

    1-A watches Aizawa and (Y/N) leave from the windows. Shoto finally catches a glimpse of his sister's imposter, she's an exacty copy of (Y/N), but with one major difference. The imposter's eye has a scar over it, light pink, but deep like it was made by a knife. Her face is clearly filled with anger and resentment.

    When the real version of (Y/N) approaches her twin, the imposter's face darkens and she immediately grits her teeth and attempts to burn the hero.

    "Welcome to your final moments, bastard." the imposter hisses, "I'm the real (Y/N) Todoroki, you're just an imposter from the 'real' world. I'm Shoto's sister, I'm Rei's daughter, I'm..his daughter, not you! You deserve to be dead. Y'know, I tried to kill you that day..in the hospital, but my brother showed up and I had to leave."

    "Huh?" The real (Y/N) mutters, "How did Shoto not recognize you as me?"

    "Because I have a new quirk." the imposter says, "I can take form of anyone I've seen. At the time, I was some store owner. Maybe I've been here the entire time, stalking you for the perfect moment! You'll never know!"

    "Do you just want your life back, is that it!?" the real (Y/N) responds, "I can do that, if you want."

    "Oh no.." the imposter chuckles, "I don't want my life back. I'd rather kill off every person who thought you were me instead. So..everyone in the entire world. Since you are the Symbol of Peace, and everyone basically worships your worthless ass. Let's begin, shall we?"

    Suddenly, the ground beneath Aizawa and (Y/N), as well as Present Mic, (since he was the one who caught the imposter as she tried to enter class 1-A's dormitories), turns into small chunks of rock. Almost like a grid. The imposter rushes her twin, sending chunks of earth at her. Many pieces make contact, and cause the number one hero to fall to the ground.

    Up in the window, Shoto and the rest of 1-A can't bear to see the three heroes be beaten up by the imposter. Denying their orders, the boy with the bi-colored hair, as well as the rest of 1-A rush down to the ground. They leave their dorms and run to where the imposter is attacking. Immediately upon noticing the new heroes, the imposter of (Y/N) locks eyes with her brother.

    "Oh, hello, brother." She hisses, glaring daggers into him.

    "I am not your brother." Shoto replies.

    Ignoring him, the imposter glances at Midoryia. This evil version of (Y/N) loves him, in the same way Toga does, "It's been a while, Izu..did you miss me?"

    The voice that she uses to ask sends chills down the spines of all of the newbie heroes, and she begins to laugh maniacally.

    She turns back to her brother, "I have a question. Why didn't you save me from our excuse of a father when he attacked me?! WHY?!" Suddenly, the imposter leaps forward and grabs Shoto by the throat, slamming him on the ground. "WHY THE HELL DID YOU LET HIM HURT ME?!"

    Before Shoto can get extremely hurt, the real (Y/N) gets up off the ground and uses her rinkaku kagune to pry her twin's hands off of her brother's throat.

    "Let go of him, villain." She hisses.

    "You're the real villain here!" the twin replies, angry tears streaming from her (E/C) eyes, "You stole my life from me! You stole my brother, my friends, my..my lover. You stole everything! I should be the number one hero, I should be standing in your place!"

    "Give it up, imposter." Katsuki mutters, rolling his eyes, "The real (Y/N) is standing there because she's a hero. She didn't steal anything from you. You were the one who didn't come back. Where were you when she came to UA with a stricken look on her face? Exactly, not there. You had months to come back and reclaim your seat in the classroom, but you didn't. You took this upon yourself."

    The imposter laughs again, "Look who's talking! You're the one who nearly killed Izu because you were in love with me! Izu was in a coma because of what you did..and I will never forgive you!"

    Suddenly her left side in on fire, and she sends the hot flames towards her former classmates. They all easily dodge the attack. The real (Y/N) creates a protective wall of earth. When the heat disappears, she drops the wall and rushes her twin, letting her rinkaku kagune appear out of thin air and slice at herself.

    The imposter drops to the ground, grunting. She leans up and glares at the hero version of herself, grinding her teeth.

    "Looks like someone else got a new quirk or two." SHe mutters, getting on her feet, "Well, I did too!"

    Suddenly a bright red light begins to emit from the imposter's stomach. It grows so bright that class 1-A and the other heroes have to shut their eyes and cover them. The red light eventually turns into a piercing beam. Upon doing this, the real (Y/N) notices one of the walls nearby begin to corode, as if it's being melted. Manipulating the ground beneath her, the hero (Y/N) creates a ball and encases her classmates and heroes inside, protecting them. The imposter's laser becomes stronger, and begins to pierce through the boulder of earth, so (Y/N) drops it and creates a kagune out of an ukaku and a rinkaku. She blasts small blades from the ukaku kagune and uses the tentacle-like rinkaku to stab at her twin.

    The imposter drops to the ground, but doesn't stay in the position for long. She eventually gets up, wipes the drip of blood from her mouth and grins crazily, "Thanks for that.."

    Her right side suddenly encases in a clear substance. Except, instead of being ice, it's crystal. Her evil smile darkens, and she touches the ground below her with her dominant hand. Upon doing so, the entire area becomes encased in crystals, restraining the heroes as well as class 1-A..all except for hero (Y/N) herself.

    "Now that the others are out of the way, I'm going to kill you." the imposter hisses, "Then I'll finally have some type of closure."

    Her hero counterpart rolls her eyes, "My quirks are stronger than yours, and have many more uses. I doubt you will be able to kill me. It won't give you any closure, you'll feel guilty for killing off the someone who saved lives from villains such as yourself!"

    "Oh shut up.." the villain replies, sending a large flame towards her enemy, "Die already."

    The hero dodges her attack with ease, then sends ice and earth towards her twin. Her twin jumps over the attack and begins to emit a bright red light from her stomach, except, after a few seconds, the light begins to emit from every part of her. It blinds the hero (Y/N) long enough for the villain version to rush over and stab her through the stomach with a crystal sword of her own creation.

    The hero flops over to the left of her twin, gasping for air and spitting up blood. Terrified looks fill the area, leaving the imposter with a happy grin spread across her face.

    "There, you're dead." She mutters, rolling her eyes.

    "A-Are you insane?!" Midoryia finally yells through his tears, encased in crystal.

    The villain counterpart of the real (Y/N) giggles, approaching the green-haired boy, "For you? Of course. I love you, Izu."

    Shoto, who is encased in crystal not very far away growls, "He's my boyfriend, imposter. Touch him and I will personally turn you to ash!"

    "Oh really?" the imposter replies, quickly pulling her hand away from her childhood friend, "How disgusting."

    As the two argue, Sato and Jiro are planning in the back of the group.

    "If you can use your free arm and reach to get the pack of sugar in my pocket, I can break free and get the others out." Sato whispers, the purple-haired girl nearby nods.

    She leans over as much as she can without gaining the attention of the imposter of (Y/N), and grabs a few sugar cubes. She shoves them in her classmate's mouth, and he immediately powers up. Sato breaks through the crystal holding him hostage, and does the same for his comrades. The imposter growls, rushing him. Thankfully, Aizawa cancels out the villain's quirks, and Midoryia uses one for all to restrain her to the ground.

    The villain's dominant hand goes down into her pockets though, and comes back out with a dart. She throws it at Aizawa, who dodges it, but still reflexively blinks. This gives her the chance to get up and emit a bright red light once again. Everyone shields their eyes, but the villain doesn't stop there. She then takes the chance to grab her dying twin, creating another crystal sword to stab into her, but this time, into her legs; to keep her from moving.

    Shoto quickly stops the imposter from attacking a third time, and freezes her entire body. The police soon arrive, preventing the villain from using any of her quirks to get out of the situation. As a quirk-canceling device is slapped around her neck, class 1-A and a few nurses rush over to see the hero (Y/N)'s condition.

    A small crystal sword protrudes from both of her legs, there is also a rather large hole in her stomach that is bleeding heavily.

    "We should get R-Recovery Girl, right?" Midoryia mutters, staring at his best friend's limp body.

    "I honestly don't think she's going to make it to the hospital." One of the nurses mutters to her colleuges, "What should we do?"

    Aizawa places his hand on Midoryia's shoulder, "Recovery Girl went home for the day, only the hospital can save her now."

    Eventually, (Y/N)'s wounds are bandaged the best they can be, and she's carefully placed on a stretcher. She's hauled off to the hospital, with Shoto, Katsuki, Kirishima, and Midoryia sitting in the four seats of the ambulance, absentmindedly staring at their classmate's peaceful expression.

    At the hospital, the four friends sit in the waiting room. Currently, the doctors and nurses are doing their best to stop (Y/N)'s wound from bleeding, and keep her alive. Her class is worried, but the four who sit in the waiting room are the most terrified out of everyone. Especially Katsuki and Kirishima. Shoto is also terrified, but there's still a sliver of hope that resides within him. Midoryia, he trusts the hope that his boyfriend has. Kirishima and Katsuki will never be able to know which of them that (Y/N) was going to chose to be with forever, and that will haunt them the rest of their lives if they never find out.

    The click of heels makes all four of the boys glance up. A woman with long brown hair and dark brown eyes stares back at them. Her face is not happy nor sad, so no one knows what's coming.

    In her hands is a clipboard, she glances down, reading off of it, "I'm guessing that you four are (Y/N) Todoroki's classmates?" She notices Shoto, "You must be her brother. Come with me, please."

    She turns on her heel, and immediately the four boys get off of their chairs and follow her with stricken looks on their faces. After a few moments, the five reach a section of the hospital that is meant for critical condition patients. Shoto feels a pang in his heart, but he continues to follow the woman in front of him.

    The woman opens a door, peaking in before opening it all the way and entering. (Y/N) lays on a bed with many monitors hooked up to her. Bandages cover her shoulder and stomach, while she's only wearing a sports bra and a blanket to cover the rest of her body.

    "(Y/N) suffered many injuries during that battle." The woman explains, "She has two broken ribs, a shattered collarbone, and the hole in her stomach has damaged her respiratory system badly. She's in a coma at the moment, and frankly, the doctors don't know if her body can wake up from it. She's weak, and is in constant pain."

    "Goddammit.." Katsuki mutters, pushing back his tears.

    "I know this is hard to hear, but there may come a time where it'd be best to pull the plug. Her lungs were damaged in the attack, so if her oxygen mask is removed, that will end her suffering." She adds.

    "Can you..leave us with her?" Shoto asks, clenching Midoryia's hand, "I-I'll think about what you've said.."

    "Of course, sir."
