Read to find out! My hero Academia: A Two-Headed Girl's Fight for Control

Misaki, facing an army of her own mirrored doubles, was almost overwhelmed by the sheer confusing spectacle in front of her. But, she could not afford to let fear take control. Her heart pounded in her twin chests as she focused, placing all her four hands onto the ground. She felt the familiar sensation of her quirk activating and her body began to split, creating more and more duplicates. Her hive mind was filled with the sounds and sights of a dozen perspectives, causing her to stagger slightly. It was exhausting, but she managed to surmount eleven clones total to match the villain’s manipulated copies. She knew breaking her usual limit might have serious repercussions. Severe physical and mental exhaustion could rob her of consciousness, making her vulnerable. But there wasn't time for these fears. Misaki, with a determined look in her two pairs of eyes, commanded her battalion of identical selves to engage her control-less counterparts. Syouma, on the other side, rushed towards the villain, exploiting their focus on Misaki to get closer. He absorbed a blow with a wince from one controlled duplicate, storing up the kinetic energy for later. Misaki’s duplicates fought fiercely, wrestling with the controlled clones, trying to keep them engaged and limit their ability to duplicate. However, the villain was cunning, and every time one of Misaki's clones got too close, another controlled duplicate would be made. The situation was starting to look grim, but then Misaki had a thought. As she looked at her clones under the villain’s control and her own hive mind, she realized that her control-less duplicates were only copying her initial state – two heads and four arms. They didn’t have her later gained knowledge of the hive mind, her extensive training on how to keep duplicates coherent, nor the bond she and her duplicates had formed over time. Misaki remembered that her quirk had another facet. When she wants, she can also re-merge her clones. It drains her strength, though much less than duplicating, but the idea sprouted a plan in her mind. "Guys, I need you to get as close as possible to the enemy clones. Don't hold back," she commanded her clones telepathically. Knowing the risk, her clones obeyed. The villain, seeing the originals approaching, allowed more controlled duplicates to be created. Misaki clenched her eyes shut, focusing, and pulled the duplicates back within her body, one by one. Her stomach churned, her muscles convulsed in twitching recoil. Each fusion drained her, but she forced herself to keep going. The controlled clones started to stagger, losing their number advantage. As the controlled clones thinned out, the villain realized too late what was happening. In the meantime, Syouma had reached the villain. With an angry yell, he released the stored energy, his arm shooting forward like a bullet, landing a powerful punch. The villain was thrown several feet away, unconscious even before she hit the ground. Exhausted, Misaki collapsed. She triumphed, but at a heavy cost. With the last bit of her strength, she proudly said, "This is my quirk, Syouma. This is our victory." She looked at Syouma and smiled, as the hero reinforcements appeared on the scene, taking care of the unconscious villain and the chaos that had ensued. Their first brush with a super villain was a memory they'd never forget, a milestone making their bond stronger.
