Two days after (Y/N)'s memory was wiped, she wakes up again.

"Huh?" She mutters, "Where am I?"

The League of Villains enter altogether, as Tenko runs up to the (H/C)-haired girl and wraps his arms around her.

"Thank god you're okay!" He says, smiling.

"H-Huh?" (Y/N) responds, "W-Who are you guys?"

Tenko shyly chuckles, "Oh right, the Doctor said you might not remember anything..well, I'm Tomura Shigaraki. This is Himko Toga, Jin- just call him Twice, Spinner, Mr. Compress, and Dabi. We're your friends. Do you remember anything about your life at least?"

The girl nods, "I remember...my name is (Y/N) (L/N). I used to be a hero going to school at UA high but then they cast me out because they thought I was too powerful. I came to you guys and you helped me get stronger and I became a villain. My father is the number one hero and he burned me when I refused to work..but my siblings, did nothing to help. You guys were the only people I could look up to."

Toga smiles to herself, "We're here for you, (Y/N)!"

"Wow, you're using my first name, we must be really good friends then!" (Y/N) responds, hugging the blonde girl.

"Yeah..friends.."

The League of Villains and (Y/N) spend a few minutes 'catching up' before Tenko decides that the quirk-canceling device around the girl's neck can be removed.

"Why was that thing even around my neck?" (Y/N) questions.

"Well, your quirk is so strong I was worried that it might activate while you were asleep." the blue-haired man replies, "It was just a precaution."

The girl in front of him nods, rubbing the area that was covered by the device. Thoughts drift throughout her mind though. She doesn't remember spots in her life that should be there. Her favorite food.. favorite songs.. favorite shows, they were all gone. The only people other than the League of Villains that she remembers are her family, and the teachers at UA. She has no idea that anyone in class 1-A even exists.

"Now how about we get to training you?" Tenko suggests, "Your body must be stiff after your long nap."

And that's the beginning of a long, bumpy road in (Y/N)'s life.

Back at UA high, class 1-A has gotten a day off because Mr. Aizawa and majority of the other UA teachers are off searching for (Y/N) for the fifth time this week.

"God, where are you?" Midoryia mutters, staring at a picture of (Y/N) and himself from when they were younger.

Uraraka turns the corner with Iida at her side, "Deku, the girls and I are-"

She cuts herself off as she glances down at the couch. Midoryia sits with the picture of (Y/N) and him on the floor. His hands cover his mouth as tears flow and his green eyes are dull.

"Deku.." Uraraka mutters, staring at the boy.

She slowly approaches him, as does Iida. The two friends hug the green-haired boy tightly. He lets out a squeak at the sudden contact, but eases into the hug and cries on their shoulders.

"It'll be okay, Midoryia." Iida mutters, "They'll find her."

Kirishima, Katsuki, and the three other members of the Bakusquad sit together in Kaminari's room, in silence. All of their eyes outlined in red- due to the crying that they've all been doing.

"She was supposed to be in the real world.." Katsuki mutters, "If she had just gone back there, this wouldn't have happened. Dammit, why was she such an idiot!?"

Sero sighs, patting the blonde boy's back lightly, "I think this might've happened anyways, but it would've been one of us. (Y/N)'s a strong woman, I'm sure she's fighting against those villains. Hell, she might've already escaped them. She might be running around Hosu trying to hide her identity until she knows it's safe."

"But what if she's not!?" Kirishima yells, startling his friends.

Although the redhead was usually calm and rational, ever since (Y/N) went missing, his grades were dropping even more than usual, and he has been having major outbursts, just like Katsuki.

"What if they've hurt her!?" He continues, "Maybe they just sent her back to the real world, maybe they..m-maybe they..what if they killed her?!"

Ashido bursts out crying at Kirishima's words, "N-No, there's no way they would've killed her. S-She's probably just tied up, that's better than being killed..right?"

In a way though, Kirishima is correct.

The hero, (Y/N) Todoroki that class 1-A knows is dead, her name is (Y/N) (L/N) now, and she's a pure villain. Or at least, that's what Tenko made her into.

Soon all of class 1-A gathers in the common room, trying their best to keep their tears at bay. They all sit down on the couch, but right away, Midoryia notices that someone is missing.

"Huh, where's Todoroki?"

"I'll go check on him." Kirishima mutters, shoving his hands in his jean pockets and heading towards the elevator.

When the redhead gets to Shoto's room, he reaches up to knock but he instead puts his ear to the door and hears nothing. Trusting his instincts, Kirishima opens the door and Shoto's dorm room is completely bare. It seems that the bedsheets haven't been touched in days, there's a small dust pile forming on his desk.

The red-headed boy rushes out of the room, hoping that Shoto didn't run off to find his sister on his own. He rushes into the elevator and heads to (Y/N)'s dorm room. He puts his ear to the door and he can immediately hear the sobbing of Shoto as he grips onto the bedsheets of his sister's bed.

"Todoroki." Kirishima says from the other side of the door, "Can I come in?"

The bi-colored boy on the other side freezes, "A-Alright."

The redhead opens the door to reveal Shoto sprawled out on the floor. (Y/N)'s bedsheets are spread out across the floor, while her perfumes are found by Shoto's knees. Glancing up at the boy's face, Kirishima can easily tell that Shoto hasn't been eating or drinking as much as he should, he's only been crying.

The red-haired boy gets onto his knees and says nothing, he just leans over and hugs Shoto tightly. The boy in his arms bursts out in tears and hugs Kirishima back. The two stay in that position for a few moments, before Shoto pulls back to wipe a tear from his eye.

"Have you been sleeping here ever since she went missing?" Kirishima finally asks.

Shoto slowly nods, "I-I can't take it anymore. I can't live without her..she wasn't my blood sister but, she's still my sister and my heart aches that I can't see her. So, I've been staying here. Just knowing that she's been here before helps me stay calmer. I-I miss her, so much."

Kirishima sighs, feeling his own tears begin to rise, "I know, Todoroki. We all miss her."

There's comfortable silence for a few moments, until a certain blonde suddenly kicks open the door.

"What are you two losers doin-" Katsuki cuts himself off as his eyes scan (Y/N)'s room, and then they finally land on Shoto's sunken face and dull eyes.

"Shit, I guess you're pretty hurt about (Y/N) too." He mutters, sitting down beside Kirishima.

Shoto only nods.

Katsuki sighs, "I'm sure that they'll find her. (Y/N)'s strong, she won't let a couple of villains control her."

"What are you three doing here?" Iida suddenly appears in the doorway with a stricken look on his face.

"What's wrong, Iida?" Kirishima immediately asks.

"It's (Y/N), they've found her."

The three boys practically jump off of the floor and rush into the elevator. When they enter the common room, Mr. Aizawa stands in the middle. On his face though, is not his typical scowl, the man instead, looks terrified and full of sorrow.

"As Iida has said, we found (Y/N)." Aizawa begins, "There's one problem, she seems to be..happy. The League of Villains are located near the city where (Y/N) was first taken away from, but the girl seems to have no idea that she's been kidnapped."

Shoto's eyes begin to fill with tears, as possible reasons for this flood throughout his mind.

"We may have to assume that (Y/N) was brainwashed." Aizawa finally says, snapping class 1-A's hearts in two. "If this is true, does anyone know a significant moment in (Y/N)'s life that might be able to bring her memory back?"

The class stays silent for a moment, and eventually, Aizawa sighs, "Alright, I can tell that everyone is too shocked to respond. IF anyone has any ideas, contact me. I'll be planning with the other heroes in the faculty lounge."

Shoto drops to the ground as Aizawa exits the dormitories, his classmates rush to grab him but his left side begins to flame up.

"DON'T TOUCH ME!" He screams, shocking his classmates.

"Todoroki, we know you're angry." Iida says, "We all are angry, but that doesn't mean we can let the emotions take over!"

Midoryia stares at the two boys as they yell at each other, and finally, the green-haired boy charges up One for All and smacks Shoto across the cheek with 5%.

"Enough." He hisses, "(Y/N) will be okay. You Todoroki, of all people, should know that!"

Shoto stares in the distance while holding his cheek, the only other time that someone hit him in his life was his father. And he still hates his father. Midoryia hitting him reminded him of when (Y/N) tried to rebel against the number on hero and got burnt.

"You..y-you." Shoto's anger has reached the limit, his left side's flames start to burn the people standing near, while his right side becomes encased in ice and begins to freeze the people standing near there, "YOU ASSHOLE!"

Shoto lunges at Midoryia, which shocks his classmates but Kirishima and Katsuki stand in front of the green-haired boy and hold down Shoto against the floor.

Katsuki blasts his face and yells, "I know you're angry, icyhot! I am too, we all are! But we can bring the real (Y/N) back, unharmed and not brainwashed."

"How?" Shoto replies through tears, "What the hell can we do now?"

"I have a plan."
