Authors Note: And so we arrive at the climactic showdown! I own nothing.

Sacrifice

Izumi had hoped All Might would show but that didn't mean that she would stand down. This had been the crux of her plan. The other heroes weren't what mattered. All Might couldn't be taken down by stealing his power. She shook her head to herself as she blinked between pieces of debris. She didn't stay still too long. If he couldn't touch her he couldn't take her down. But he should never have told her that story. If he hadn't told her about One for All she would have lost hope so long ago. But as long as All Might had already chosen his successor this could work. If Izumi was honest she did not expect to be walking away from this fight. She expected her father to kill her if she lost. If she won… Well she wasn't sure what would happen if she won. She didn't expect to. But she hoped Dabi knew how much she owed him. He'd gotten Kacchan out of reach of her father.

She lifted a glowing hand and several large pieces of debris rose. Shigiraki had regained his feet along with Toga. The others were either still out cold or nursing the injuries she'd given them earlier. But Shigiraki was the dangerous one now. She couldn't let him interfere. She hadn't expected her father to force Kirogiri and Magne's powers to send Shigiraki and his goons off somewhere. Whatever, it didn't matter. What mattered now was taking down her father.

Dabi wanted to scream. Teenagers were impossible, he should know he'd been working for one for a while now. But he hadn't thought there could be someone in the world as stubborn as Izumi Midoriya. Katsuki Bakugou was proving him wrong.

"You can't help her!" The blonde had the audacity to growl at him and he rolled his eyes as the other teens watched the exchange.

"Like hell I can't." Dabi grabbed the boy as he tried to race out onto the battlefield where All Might and All for One were clashing and debris was flying, some glowing and attacking All for One, others naturally tumbling through the air. He threw the boy into the redhead and pushed Shoto and Ingenium's little brother down as debris rained. The fight was getting too close for comfort.

"You don't know what this man is capable of! I do." But the boy had taken off in the opposite direction, away from Dabi and around the wall to where the battle was raging. Dabi made to follow but swore as he was forced to throw up another wall of flames to defend them from more flying debris. The flames were so hot they stayed blue even after he stopped shooting them and the rocks melted as they flew through it.

"We need to get you lot out of here. Now!" The redhead spoke up.

"What about Bakugou?!" Dabi shook his head.

"There's nothing I can do to help him now. I need to get you lot out of here. I just hope All Might can handle him." He grabbed Shoto's hand and Ingenium's little brother nodded to the others. They ran, Dabi glancing back over his shoulder. He prayed that Izumi would see Katsuki, take him and run, but he had a sinking suspicion that she wouldn't stop not until her father was dead.

She spotted her father's head move slightly as he endured another punch from All Might before she spotted the boy on the other side of the battlefield. Everything seemed to slow down. All sound dropped away, the crackle of the fires Dabi had started, the clatter of the debris she'd been using falling, the beat of the blades from news helicopters staying just far enough away from the fight to not be a nuisance and still get everything on camera. Everything dropped away as the world moved as if trapped in syrup. Her father's arm moved under All Might's. The hero hadn't spotted him.

Izumi didn't remember moving, she didn't remember activating her teleportation. All she knew in that moment was that she had to get between Kacchan and her father. She would not lose him. She would not have him be one of her father's victims. In one instant she was crouched behind a rock, the next she was in front of Kacchan arms thrown out to defend him.

Katsuki Bakugou had no idea what was happening. One second he'd been alone on one side of the battlefield waiting to get a good shot at the monster who had taken Izumi from him, the next she was in front of him, her arms thrown out as if reaching for an embrace. But before he could take hold of her she let out a bloodcurdling scream. There were things digging into her shirt and the skin of her back, sinking in deep. With a single jerk she was yanked away from him as he cried out in fear for her. He scrambled to reach for her but the monster that called itself her father was too quick. In an instant she was gripped in his now gigantic hand. She was still screaming the horrible sound echoing around the craterlike field. All Might swore as he stopped short.

"You couldn't just listen to orders could you? I'm disappointed in you." His tone was reprimanding, like he was telling his child off for getting caught with her hand in the cookie jar not for saving someone.

"Go to hell!" She shrieked as the things that had dug into her pulsed. All for One shook his head.

"Such a disobedient child. You know what happens when you break the rules." The tendrils under her skin pulsed again and she howled in pain. Katsuki was sobbing, he wasn't sure when the tears had started but he knew that there would be no stopping them. She was going through this because he hadn't listened to her lackey and run when he was told. This thing that called itself human seemed to be watching her pain with interest, his helmeted head was tilted slightly. Her hands dropped from his enormous fingers to her sides and for a second Katsuki thought she had died and all breath left him as if sucked out. Then she spoke.

"Fuck you." Her hand moved and there was a flash of metal through the air as a knife sunk deep into All for One's shoulder. He shouted in pain at the same time his daughter did. The tendrals had ripped themselves from her skin sending blood flying through the air. With nothing to hold her up anymore she dropped and would have struck the hard concrete of what was left of the street but All Might was too fast. He snatched her up and dodged backwards as All for One attempted to dig the knife out of his shoulder. Katsuki dodged out of sight as the villain roared in frustration. He opened the hand of his uninjured arm and pointed it at All Might and Izumi. The rocks around them shook then descended upon them making as though to crush them. Katsuki screamed in protest as his hero and the girl he loved disappeared from sight.
