U.S.J

The next day

Isabella was walking to school and arrived at the gates, when she was swarmed by reporters. They shouted in her face "What do you think of All Might!?" Isabella covered her ears and said "Can you stop shouting, please. I'm not deaf." The reporter repeated the question and Isabella said "I don't know. He's nice? Why do you care? It's not like you'll ever get a chance to interview him, just scram out of my way. Some people!"

She pushed the people out of her way with the sand and walked into the school, leaving the reporters speechless. That was a critical hit. Isabella 1 Reporters 0.

Hiro was standing across the street and chuckled before turning around and walking away, he bumped into a young man with white hair and bags under his eyes. Hiro looked at the kid and glared at him, scaring the kid silly, as he walked away.

[Decay added to All For One]

Hiro smirked and went back to his shop. He just copied Shigaraki's Quirk, he didn't steal it. Isabella needed the experience! He wasn't going to interfere too much. His business was doing just fine at the moment and if his plans go well, he should be able to get into U.A soon.

He was going to move after today.

He chuckled to himself and flickered, disappearing from the street.

A while later

Isabella was eating lunch with Izuku, Tenya, and Ochako when an alarm went off. Isabella blinked and looked around at the scrambling kids, she didn't move and stayed seated. She was eating, this food costed money!

The scrambling kids were calmed down by Tenya and everyone relaxed. Isabella was still eating and blinked at Izuku, who came back and said "You didn't move?" Isabella pointed at her food and said nothing.

A while later

Aizawa got everyone in their Hero Costumes and on a bus to U.S.J to do a rescue class. They were sitting on a bus and riding to U.S.J as the group talked. Isabella invited them to Hiro's coffee shop and the group agreed to go after class today.

Well, almost all the group.

The loners didn't want to come.

Izuku warned everyone that Isabella's dad was really scary. They all laughed and brushed it off, how scary could he be? They would find out that they were extremely wrong later.

The bus arrived at U.S.J and the class walked inside, greeted by Thirteen, the Space Hero. She explained what the class was and that their Quirks can kill someone very easily. Isabella asked "Don't Heroes kill Villains?"

Everybody looked at her funnily, Aizawa looked at Isabella, and Thirteen shook her head saying "No. Your Quirks aren't for harming others." Isabella gawked, extremely confused. This was not what her Baba said and did. Thirteen explained that villains were jailed after they are captured.

Aizawa looked at Isabella's confused face and said "What do you think?" everyone looked at Isabella, who said honestly "That's the stupidest thing I've ever heard." the class gawked and Aizawa's expression was unreadable as he said "Why?"

Isabella explained "If you can't kill villains, then some Heroes can't do all out and fight to their best. If you're worried about accidentally killing a villain then you're likely to get yourself hurt by holding back. Also, why would you want to hold back? Some villains are truly evil people! It's better if they die. Plus, if you put them in jail, they'll just escape again and continue doing what they were doing before. If you lock up a rapist and they escape, isn't it your fault if he rapes more people? If you kill him then you're saving more than just the people at the moment."

Aizawa retorted "If you kill a murderer, doesn't that make you a murderer as well?" Isabella countered "But if you kill 100 murderers aren't you a hero?" Aizawa had no reply to that, if one person killed 100 other murderers, who knows how many people they would've saved instead of letting them go.

Isabella scratched her cheek and said "Sorry..." Aizawa said "It's fine. You're not wrong, but there's laws. We can't do anything about them." Thirteen said "Aizawa-san!" Aizawa shrugged "It's true though, I've had accidents on the job before. They're inevitable. The paperwork after is horrible."

Isabella covered her mouth and chuckled silently, while the rest were lost in thought.

Hiro smiled, listening from Isabella's shadow. She wasn't wrong at all, it was kind of dumb how people just let the villains go to jail. Like All Might for example, at the peak of his Quirk, Hiro had no doubt a full strength punch would obliterate someone out of existence, doesn't that mean he has to hold back all the time? Maybe he wouldn't have been injured if he didn't hold back?

Hiro didn't know the circumstances of All Might's fight with All For One, but he assumed All Might wasn't trying to kill him or rather trying not to kill him. Hiro didn't care either way. He didn't follow the rules normally and he wasn't going to start now.

Isabella was standing with the group as the lights dimmed and a portal opened in the middle of U.S.J. Aizawa reacted right away saying "Thirteen! Protect the kids!"

Hiro turned invisible and left a shadow clone in the Shop as he came out from Isabella's shadow and patted the heads of all the kids, Thirteen, and Aizawa before speeding through all the villains and tapping them all.

He tapped the metal collar of Kurogiri and the brain of the Nomu.

He took all the Quirks, even the Mutation ones, sucking them into his All For One. They all felt something touch their heads for a split second before disappearing, nothing was wrong so they brushed it off.

Hiro stood on a fake mountain and watched as the U.S.J attack unfolded. He grinned to himself as he felt all the Quirks in his body. They were all upgraded by the All For One quirk to be toggleable. He didn't change at all, the only thing that was different was the powers he had at his disposal.

He wanted to see what Isabella would do when faced in unfavorable situations.

++++++++++

Isabella looked at the villains and spread her sand, grabbing everyone before flying into the air, bringing them along as she retreated to the entrance of the U.S.J building. They landed on the ground and some of the kids thanked her.

Isabella looked at the villains and said "We gotta help, Aizawa-sensei." Tenya said "No, we should run." Isabella opened her eyes wide and said "And leave him alone!?" Tenya nodded, Isabella gawked and said "You can run if you want to." before flying towards Aizawa as Tenya shouted "Isabella! Come back! Those are real villains!"

Isabella shouted back "And I'm a REAL hero!" before swooping down and kicking a villain flying. She stood back to back with Aizawa saying "I'll help, Sensei!" Aizawa said "You should've run." Isabella kicked the air, sending a black sand blade flying from her leg, blasting a group of villains flying as she said "There's too many for you, sensei."

Aizawa sighed and said "What a headache..." as he shot out his binding clothe and tied up a bunch of villains, swinging them into each other as he cancelled their quirks. Isabella made a sandstorm and pushed it into the group of villains before dropping to the ground.

A hand reached out for her and she dodged it before shooting her leg out saying "Damn pervert!" Tomura was kicked in the stomach and sent flying into a rock, coughing up blood. Isabella puffed her cheeks and said "Sure enough, bad guys are all perverts."

The villains paused for a split second in grief. They weren't perverts! Aizawa made use of their pause and thrashed them around as some of them disappeared into portals.

Isabella grabbed Aizawa and flew into the air as the ground turned into sand and spun, making a sand pit, sucking in the villains. Aizawa said "Good thinking." Isabella was silent and said "The rest of the class was separated, but Tenya left.

Aizawa said "Cancel the sand pit and go help the others." Isabella said "Sensei-" Aizawa said "Now." Isabella cancelled the sand pit, leaving the villains trapped in the ground as she put Aizawa down and flew around U.S.J, saving her friends though they were doing just fine on their own.

Isabella floated in the air looking at everything and choosing to help people based on whether they were struggling or not.

A few minutes later

Isabella was with the group again and they went to help Aizawa all together, beating the villains around. Isabella jumped out of the way of a portal and looked at the black mass guy. Thinking of how to beat him.

She saw a metal flash in the wisps and punched at it, she connected with Kurogiri's collar and sent him flying with a cracked collar. Tomura looked at Kurogiri and said "Damn bitch!" Isabella twirled out of the way from Tomura's palms and grabbed his arms, slamming him on the ground, she reached into her ninja bag on her waist and handcuffed him.

She backed off and ducked under Aizawa's body as he flew over her, coughing out blood. She turned around to see the Nomu looking at her. She made a disgusted face, this thing's brain was showing!

It punched at her and Isabella jumped over it, landing on the Nomu's shoulders. She touched the Nomu and dehydrated it as it thrashed around. The rest of the class handled the villains and Tomura was struggling in the handcuffs, trying to touch them with his hands, but they were '∞' shaped handcuffs, he couldn't move his wrists enough to touch the metal.

The Nomu punched forward and into a portal, Isabella was punched in the back and exploded into sand before reforming off the Nomu. Only elemental attacks could hurt her, nothing physical. Well, maybe strange magical attacks could do it too.

Suddenly, a shadow smashed into the Nomu and sent it flying as All Might revealed himself and said "Have no fear! For I am here!" Isabella said "All Might-san!" All Might gave her a thumbs up before fighting with the Nomu.

Isabella made the ground under the Nomu turn into sand and it lost its footing as All Might punched the fuck out of it. Isabella merged into the ground and her hands shot out of the sand, grabbing the Nomu's ankles and dehydrating it quickly.

The Nomu withered and All Might punched it in the brain, blowing the brain to paste. The Nomu fell over and Tomura scratched his neck saying "Retreat" before disappearing with Kurogiri. Hiro grinned as he looked at Isabella, what a good girl!

She did amazing!

Hiro flickered in front of All Might and waved, putting up a black barrier.

All Might was alarmed and got punched out. Hiro caught his fist and didn't move an inch. All Might coughed up blood and was stunned, this guy was stronger than that thing! Hiro looked at All Might and smiled "Hello!" All Might started steaming and said "Who are you."

Hiro blinked and tapped his horns saying "Isabella's father." All Might relaxed slightly and Hiro smiled "You really have weakened though..." All Might tensed up and Hiro added with a wave "Anyway! Come to 'Oni Coffee' whenever you're free..." he smirked "In your weakened form too, if you'd like."

All Might was alarmed and Hiro smiled before adding "Let's keep my identity a secret, okay?" he sighed and said "I really don't want to be swarmed by reporters, heroes, and police. It's annoying... Anyway! Bye!" before disappearing into thin air as the barrier dissipated, leaving All Might silent in thought.

He had to go now. It seemed he knew about his true form. All Might needed to figure out how much Hiro knew and see if he could keep quiet about it. Isabella ran over and looked around cautiously, on guard saying "All Might-san, are you okay?! What was that barrier?"

She stood in front of All Might, ready to fight. All Might smiled and said "Not an issue!" as he coughed out blood. Isabella's mouth twitched and Izuku ran over saying "All Might!" he stopped and said "Izzy? What are you doing here?" Isabella said "Beating up perverts!" as she swung her fist.

All Might laughed and the teachers showed up, blocking off the area and securing the students before capturing the villains.
