"It's such a kind and gentle Quirk."

     When Aya saw that the white-haired commander of the Paranormal Liberation Front was unleashing noumus near Deku’s and the place he’s interning at, she didn't waste a single second before she went barreling out of the teacher's dormitory. She didn't listen to All Might calling after her, instead shifting into her noumu form to run off to the battlefield at frightening speeds. He's there. Even though it was being shown through live broadcast, she knew exactly who was really there: Papa.

       It was Papa. He’s somehow using Master's body like a vessel. Being aware of his presence practically flooded her body with j o y. Oh, how she'd love to hear him address her again. It'd been so long since she's ever heard his voice, she wanted to see him so badly again... But that feeling also brought a terrible pang of guilt and shame through her throat and guts at the same time. Even though she retrieved all her lost memories, her body was still reacting so joyously for her 'savior'... No, she should be full of fear for all the heroes over there, especially Deku. She knew both Master and Papa's capabilities, knew that not even the young hero could stop him. He'll die by Papa's hands. He might even die before Papa could reach him thanks to the other high-ends. All the heroes are gonna die... They'll die. They’ll all die...

               --Not on her watch.

    It was right before any high-ends specifically targeting Deku could lunge for him when a massive figure crashed in-between to leave a sizable crater on impact. Familiar black tendrils were wildly flaring out like a shield for her dear hero as the cloud of dust began to settle. That sheer amount of malice emanating from her tiny, little frame was enough to temporarily stun the noumus where they stood. This was Doctor's greatest creation, after all. Not even the combined powers of all the high-ends present could overwhelm her once she's like this.

            "NOBODY. HURT. DEKU."

    Deku was calling her name. He probably wanted to ask what she's doing here and why, then maybe tell her to go back before she could get hurt... But before he could even finish his sentence, one of her tendrils had suddenly shot out backwards to pick him up and pull him away from the sudden onslaught of attacks. They’re there to obey Papa and not her, after all. Even so, she easily blocked and evaded the barrage, all while having that one tendril gently place the young hero down on safer, solid grounds away from harm. Handling noumus was cakewalk for her. She had the powers to fight and win, so she'll use it for just that.      She'll use it for good. For Deku. Especially Deku.

    There was no need to worry about her getting hurt. Even if one did manage to land a hit, Aya had the power to quickly revert herself back to optimal conditions. Her strength, her power, her unquestionable combative skillsets there on the battlefield... Had she had the moment to think about it, she probably would've realized how this would've been the very first time Deku's actually seen her on the actual offensive. Deku would've realized how lucky he was on the day that they finally met again after her disappearance, when she was having other lesser noumus wreck havoc rather than causing it herself. What fell before him was a noumu massacre. She fought to kill the enemies without a shred of mercy. No being could stop her, not even Deku if he truly wanted to try and kill them off himself...

    ..The only thing that did stop her.. was him. Aya finally crushed the last noumu's head when his voice had finally rung out to her. He was congratulating her, praising her, prompting her to shrink back down to the body of a young girl with nothing more than dark mass coating her face, arms and back. It was him. He was calling out to her. It felt so wondrous to hear him again. Papa's voice alone held so much influence that it even drowned out Deku's desperate shouts to bring her back to reality...

    He and Master only wanted to test her, it seemed, to see her grow. She failed to keep her faith in him, but that's okay. Aya was just so important to him. He's so, so proud of her... He loved her, wanted her to come back. Papa was so willing to forgive her for everything she's done. That’s just like him to be so kind to someone like her. They both knew that they she still cared so much for him anyways. She did care about him, didn't she...?

       ... She did. It's true. It showed in her hesitation, and the way tears were soon rolling down her face. She missed him so terribly much. She's do anything for things to go back to much simpler times when all she cared about was just receiving his praise and love. In fact, she would’ve been perfectly fine had she never recovered any of her past memories. She wouldn’t have had to remember such a painful upbringing, instead believing that the one he provided was all she ever knew.      She could have that again, that blissful, ignorant life. He’s offering her to come back. Anything for Papa. He loved his sweet little girl, and she’d do anything for him...

    And yet.. therein lied the problem. Aya.. had to kill the boy behind her if she wanted that. She had to kill Deku, her light of hope that stayed even when she turned towards darkness. Turning to look at the young hero must've brought so much anguish and tension in the air. The look in his eyes hurt her so much... It was so tempting to forget everything, to forget all the pain and misery and suffering she went through...      ..But if there’s anything that Deku showed her, it’s that it’s thanks to those things that she became such a loved little girl who loved everyone back.      So she couldn't do it. She wouldn't.

She won't do it.     She won't be tricked and used anymore...!

Never, ever again--!!

          EVER!!

     Right. Aya didn't want to. She wasn't here for Papa. She was here for Deku. She was here for her own reasons. She came here because she didn't want Deku getting hurt in the first place. That’s her choice. Papa's words can't control her any longer. She was never even his to begin with. Aya didn't have any remorse over the fact that she was now turning the powers he bestowed upon her all against him. She's free from his control. Her fighting him would prove it.       And so, she fought, turning towards the embodiment of pure evil with such a fierce and determined look on her face. Aya fought so valiantly under her own accord. She fought, and fought, and fought until All for One finally found his opening. Landing a piercing blow through the black mass and its core's chest inside, he stunned her for just one second. 

     Just one second, and it was all he needed. Aya's reflexes may have prevented the shot from capacitating her head clean off, but it still ripped a terrible chunk off the whole upper right of her head. He’s damaged the head. A damaged brain for a noumu made it a useless, dead noumu.

It’s Game Over. She lost.           Aya.. can't function anymore.

    She stumbled. And then, she fell. Her fall made such a quiet impact against the ground. She should have listened to Deku. She should have listened, because then she wouldn't have had to hear such a raw, mortified scream come from the boy as he threw himself over just to pick her up. So much pain was in that scream... He shouldn’t ever have to make such a heart-wrenching cry. Oh Aya, what have you done...?      She.. She couldn't move her tendrils, or revert the damage. Her ruined head meant that she could no longer properly use her Quirks, so they dangled there uselessly as Deku pulled her desperately close to his chest, as if that’d stop all the horrors happening right before his very eyes..

    ..Deku was crying. He was so full of despair. It might be hard to tell with just one eye and a blurring vision that's quickly being consumed by darkness, but Aya could easily tell that he was crying, she could feel it. She could feel the tears spill on her face, his trembling, shaking hands struggling so much just to keep hold of her body, her tiny, frail little body. He sounded so unintentionally angry with her. His breaths were so heavy, so hoarse and painfully torn with despair, and.. he was so, so warm against her body. Deku was so warm, and she was quickly growing cold... Aya was wasting away too quickly in his arms. Death was fast approaching.      How was she even still alive at all, anyway...? Who knows...

“Dammit...! Why wouldn't you listen?” “Why did you have to do all that?!”     “Why couldn't you just leave!?” “Why Aya?!”             “Why?!?”

     So many why's... She.. really wanted to answer him. She wanted to say that it's all because he was always doing the same for her, always sacrificing everything he ever had and ever could have just for her. She wanted to tell him that she wanted to protect that glint of hope that's always been there for her, even when she was no longer herself. She was scared. She’s scared right now, fading away so quickly against her wishes.       If only she could apologize---no, if only she could just.. thank him for everything. He deserved so many thank-you’s, so, so many of them. It’s thanks to him that she could bring herself to behave as such up until the very end. It’s thanks to him that she learned to value and cherish the once thing he fought just for her: freedom. Freedom was such a beautiful thing. He fought so hard for it, and she just.. didn’t want it to go to waste... 

     ..And yet, there was only so much she could say in the last fleeting seconds of her life. So, she just.. smiled, so content with the decision she made, hoping all those thoughts and wishes and gratitude would be conveyed---that, along with a simple explanation over selfishness. How proud she looked to be selfish for once.

     “My choice. I wanted to.” Just as simple as that.
