Author Note: Some things are needed to be clarified...

Firstly, Izuku is not yet used to being a girl— but you need to keep in mind that it's been almost a year. So she had a lot of time to get used to a lot of things. But she does not like dressing up, or go to parlour or anything too feminine.

Secomdly, Izuku can change her physical age at will. But, if she uses too much(above 20%), Nezuko will come out. This is kinda' like Hulk, but not quite the same— you will find out soon enough.

Thirdly, Rewind For All, One For All and Rewind can be used separately.

Fouthly, there will be some...a lot of actions from now on. Oh, and fluffiness too, as a bonus.

Fifthly, Izuku will be forced to go on a 'Girls' Night Out'— I'm open to suggestions.

Finally, if you have any suggestions for the upcoming events, then please, do tell...

Oh, and check out my other stories...


Chapter 13


Team I vs. Team J

Team J: Katsuki and Iida

Team J: Izuku and Ochako

The atmosphere was charged with excitement and anticipation as All Might's voice boomed across the mock city. "BEGIN!" he announced, and the teams sprang into action.

Izuku, thinking quickly, turned to Ochako. "Uraraka, make the box float! Keep it as high as possible. I'll handle Kacchan."

Ochako nodded, activating her Quirk and making the box levitate high above the ground. "Got it, Deku-chan! Be careful!"

Just as they executed their plan, a blur of motion caught Izuku's eye. Bakugou had already launched himself toward her with explosive speed, ignoring Iida's calls to strategize. His singular focus was evident as he came barreling towards her, a fierce determination in his eyes.

"DEKU!" Bakugou roared, his hands sparking with explosive energy. "All these time, I thought you had become more fragile, so I wanted to protect you... but then? You stole my thunder at the entrance exam and you somehow have enough power to send a ball in another dimension?! You? a useless crybwby? I'm gonna take you down!"

Izuku barely had time to brace herself before Bakugou's kick connected with her torso, sending her flying across the street. The impact was jarring, and she skidded across the pavement, her body protesting from the force of the blow. She managed to land on her feet, her breathing heavy but steady.

Bakugou smirked, confident in his strength. "What's the matter, Deku? Thought you were hot stuff now that you got into UA?"

Izuku stood, her eyes narrowing. "Kacchan, this isn't about us. We're supposed to retrieve the box. Focus on the mission."

"Shut up!" Bakugou barked, launching himself at her again. "You think you can lecture me? You're still the same nerd you've always been!"

Bakugou's fists ignited as he threw a barrage of explosive punches at Izuku. Each punch was fueled by his frustration and pent-up aggression. Izuku dodged and weaved, her agility and quick reflexes keeping her just out of reach.

Bakugou's inner monologue was a mix of rage and confusion. "How did that useless Deku become this strong? She's not the same… But I'll show her I'm still better!"

Izuku's mind was racing. "Kacchan's not listening. He's so focused on me that he's ignoring the mission. I need to distract him long enough for Ochako to secure the box."

"Is that all you got?" Bakugou sneered, his explosions getting wilder. "Fight me, Deku! Or are you scared?"

"I'm not scared, Kacchan," Izuku replied, her voice calm despite the chaos. "But this isn't the way to settle things."

Bakugou growled, charging at her again. His movements were erratic but powerful, each explosion echoing through the mock city. Izuku could feel the heat and force of his attacks, but she remained focused, dodging and blocking.

She was holding back 99% of her power.

From the sidelines, Iida watched with a mix of frustration and worry. "Bakugou, we need to coordinate! This isn't a personal duel!"

"Shut up, Iida!" Bakugou shot back, his eyes never leaving Izuku. "This is between me and Deku!"

Izuku saw an opening and took it. She ducked under Bakugou's wild swing and delivered a swift kick to his side, using his momentum against him. Bakugou stumbled but quickly regained his footing, his eyes blazing with anger.

"Nice try, Deku," he spat. "But you're gonna have to do better than that."

Izuku's mind was a whirlwind of strategies and counter-strategies. "I need to stop him without hurting him. If I can just keep dodging, maybe he'll tire out…"

But Bakugou showed no signs of tiring. His relentless assault continued, each explosion shaking the ground and sending debris flying.

"Kacchan, this isn't who you are!" she shouted, hoping to break through his fury. "You're better than this!"

"Don't you dare talk to me like that!" Bakugou's voice was a mixture of rage and desperation. "You don't know anything about me!"

Izuku dodged another explosive punch, her mind racing. "He's so angry."

From above, Ochako watched the intense battle, her heart pounding. "Deku-chan… Be careful…"

Bakugou's thoughts were a chaotic storm. "I'll show her. I'll show everyone. I'm the best. I'll always be the best!"

Izuku could see the toll the fight was taking on him, if it continued like this then he might end up hurting himself badly. "I have to end this… But how?"

Bakugou launched himself at her with a fierce yell, his hands glowing with a powerful explosion. Izuku braced herself, knowing she had to find a way to turn the tide.

Suddenly, an idea sparked in her mind. "I need to use his own power against him…"

As Bakugou closed in, Izuku ducked low and aimed a precise punch at his midsection, using his momentum to throw him off balance. The impact sent Bakugou sprawling, but he quickly rolled to his feet, his eyes blazing.

"You're done, Deku!" he roared, charging at her again.

Izuku stood her ground, her mind clear and focused. "I won't let you win, Kacchan. Not like this.

With a burst of speed, Bakugou closed the distance between them, his fists crackling with explosive energy. Izuku dodged and weaved, her movements fluid and precise. She knew she had to stay one step ahead if she wanted to come out on top.

But Bakugou was relentless, his attacks coming faster and fiercer with each passing moment. Izuku felt the strain on her body, but she refused to let it slow her down, she refused to use more of her power.

"Come on, Deku!" Bakugou taunted, a feral grin on his face. "Show me what you've got!"

Izuku's mind raced as she tried to formulate a plan. Maybe there was another way to turn the tide of the battle.

With a burst of speed, Izuku darted to the side, narrowly avoiding Bakugou's latest explosion. She ducked behind a nearby building, using it as cover as she caught her breath and assessed the situation.

"He's too focused on attacking," Izuku thought to herself, her mind racing. "I need to find a way to catch him off guard…"

With a swift chop to the neck, he was unconscious.

She sighed in relief. That was…

Just as she was about to relax a bit, Bakugou, who was not unconscious, launched himself at her with blinding speed. Caught off guard, Izuku barely had time to react before Bakugou's explosive attack sent her hurtling through the air and crashing into a nearby toy shop.

The explosion was extremely powerful and it hit her on her face…

Izuku good feel that her face was scorched, her eyeballs were melting and her hair wss on fire…

If she did not use she would end up really messed up worse… die.

There was no other way…

'I am sorry everyone, I have to be selfish this time...'

"R-rewind Fo-for A-all…35%..."

"I hope she is down with that…" Bakugou said between his pants, he was feeling guilty for using this much power. Maybe he went overboard…

The sound of something moving caught his attention. He looked to see… Izuku?

With a sudden surge of energy, Izuku's body began to transform, her muscles bulging and her features distorting into something primal and wild. Her clothes adjusted themselves as her form expanded, until finally, standing amidst the debris of the toy shop, was a fully grown-up woman with a long horn— it was Izuku, but not as they knew her.

Bakugou's eyes widened in shock as he beheld the transformation before him. "D-Deku? Is that you, nerd?"

But there was no response from the towering figure before him, only a low growl that seemed to reverberate through the air. With a feral grin on her face, the transformed Izuku launched herself at Bakugou, her movements fluid and precise, her eyes filled with an unsettling hunger for battle.

Caught off guard by Izuku's sudden transformation, Bakugou barely had time to react before he found himself locked in a fierce 'battle' with the primal force that stood before him.

Bakugou struggled to keep up with Izuku's newfound strength and ferocity. Each of her attacks was swift and precise, fueled by an animalistic drive that seemed to have taken over her completely. And for some reason she wanted to bite him…

"Deku, what the hell happened to you?!" Bakugou shouted, trying to regain his footing as Izuku's relentless onslaught continued. He barely dodged a powerful strike that almost shattered his ribcage.

She was not using any conventional martial art— it was a mix of extremely fast movements. She used her legs too much.

"Stop it. Deku!"

Izuku, now in her primal form, didn't respond with words. Instead, she let out a guttural growl, her slitted eyes burning with a fierce intensity. She lunged at Bakugou, her movements too fast to follow. Bakugou threw up his arms in a desperate attempt to block her next attack.

"This isn't like her," Bakugou thought, struggling to catch his breath. "She's completely different... more…."

As Izuku continued to attack, Bakugou knew he had to change his strategy. He couldn't rely on brute force alone to win this fight. He needed to outthink her, find a way to exploit any weakness in her new form. He focused on staying one step ahead, using his agility to dodge her blows and looking for an opening.

Meanwhile, Ochako and Iida were engaged in their own struggle. Iida was determined to retrieve the box, while Ochako floated it high above their heads, trying to keep it out of reach. Their clash was intense, but both knew the main fight was between Bakugou and Izuku.

"I have to hold on," Ochako thought, looking toward Iida. "Izuku's counting on me."

Iida was also very annoyed because Bakugou did not formulate a plan and charged ahead. Now he had to retrieve the box alone…

Of course they had no idea how intense and brutal the fight was…

Back in the one-sided fight, Bakugou managed to get some distance from Izuku. He watched her closely, trying to figure out a way to break through her defences. "She's not thinking straight," he realised. "If I can use that to my advantage..."

He launched himself at her again, this time with a different approach. Instead of attacking head-on, he used his explosions to create a smokescreen, hoping to confuse her. Izuku hesitated for a moment, trying to locate him through the thick smoke. It was all the opening Bakugou needed.

With a fierce yell, he burst through the smoke, aiming a powerful blast at her side. Izuku reacted quickly, but the force of the explosion sent her crashing into a nearby building. She roared in anger, her primal instincts driving her to fight even harder.

Thus she snapped. Enough playing with the prey…

She disappeared from her spot before reappearing above Bakugou. She brought down her heel on his left shoulder, effortlessly breaking his scapula.

He screamed in agony as he fell on his knees and clutched his shoulder.

Izuku gave him no time to adjust himself to the immense newfound pain and grabbed him by his throat and lifted him to her eye level.

The boy was desperately trying to free himself from her grip. But she was too strong…

She gave him a grin before laughing animalistically.

He was losing his breath…

"I-I… " he managed to utter. "Deku… is n-not a monster…"

Izuku looked confused before furiously shaking her head, dropping the boy in the process.

Bakugou, now backing away, believed that he is words were reaching her…

"Deku is a crybaby… but she always…"

"Stop it!" Nezuko yelled in pure fury.

Bakugou's eyes widened as she jumped right at him and grabbed his head with her hands and…

Squeezed. Hard.

Bakugou screamed in undescribable pain.

"You liar!" She yelled and extended hard thumbs towards his eye sockets….

Just as Izuku was about to gauge off his eyes, a loud voice echoed through the city.

"Enough!"

All Might appeared in a flash, his presence instantly commanding attention. He moved with incredible speed, placing himself between Bakugou and Izuku. "This has gone far enough," he said sternly. "Izuku, calm down!"

When she didn't respond, he delivered a swift chop on her neck, making a whoosh sound in thin air. Immediately, she fell unconscious.

"W-hat the hell was that…?" Bakugou said as he looked at her, who was in her default 5-year old form.

"Class dismissed. Bakugou, the nurse's office, now."

All Might looked worriedly at his successor who was sobbing.


Bakugou made his way to the nurse's office, limping slightly. His body ached from the intense battle with Izuku, and his mind was racing with the implications of what had just happened. As he entered the office, Recovery Girl looked up from her desk, eyebrows raised.

"Another rough day, I see," she said, motioning for him to sit down.

Bakugou grunted in response, lowering himself onto the bed. "Just patch me up, Granny."

Recovery Girl tutted but got to work, applying her healing quirk and bandaging the more serious injuries. "You need to be more careful, young man. You can't just throw yourself into every fight like this."

Meanwhile, Izuku was in confinement, under the watchful eye of Aizawa. Her mind was a whirlwind of emotions: anger, frustration, and a touch of fear from losing control so completely. She knew she needed to understand this new aspect of her powers better, and fast.

After a few hours, both students were summoned to the principal's office. They walked in together, an awkward silence hanging between them. Principal Nezu sat behind his desk, a serious expression on his face, while All Might and Aizawa stood nearby.

Nezu cleared his throat. "Katsuki Bakugou, Izuku Midoriya, your actions today were reckless and dangerous. This kind of behavior cannot be tolerated in a school that trains future heroes."

Bakugou's eyes narrowed, but he remained silent, glancing at Izuku. She kept her gaze down, feeling the weight of the situation.

Nezu continued, "Bakugou, your inability to follow instructions and your aggression are problematic. As a consequence, you are suspended for half a month. If you ever engage in such behaviour again, not only will you be expelled from this school, but legal actions will also be taken against you."

Bakugou clenched his fists, his jaw tight. "Understood."

Turning to Izuku, Nezu's expression softened slightly. "Midoriya, you showed great potential today, but you must learn to control your abilities. You are given a week's leave to rest and recover. Use this time to reflect and regain control."

Izuku nodded. "Yes, sir."

As they were dismissed, All Might gave Izuku a reassuring pat on the shoulder. "Rest up, young Midoriya. We'll work on this together."

After they were gone, Nezu, All Might and Aizawa began to talk.

"If I hadn't used up all my time…" All Might, back in his skeletal form, clenched his fists. "I could have stopped this all from happening."

Principal Nezu turned to All Might. "This incident could have been much worse. We need to ensure it never happens again."

All Might nodded. "Agreed. Midoriya needs more training to control her transformations."

Aizawa crossed his arms. "And Bakugou needs to learn discipline. I'll keep an eye on both of them."

Nezu sighed. "These students have great potential, but they also have great challenges. We must guide them carefully. What do you think, Toshinori? Are we doing enough for them?"

All Might nodded thoughtfully. "They're young and headstrong, but with the right guidance, they can become the heroes we need. It's up to us to provide that guidance and ensure they learn from their mistakes."

Nezu agreed, feeling a renewed sense of purpose. The path to becoming a hero was fraught with challenges, but he believed in his students and his staff. Together, they would overcome these obstacles and help shape the future of hero society.

"Well," Nezu said. "It's a shame they will miss the USJ Rescue class with Thirteen."
