You are a new Villain appearing after the defeat of All For One and Shigaraki!/The Final war!
Itsuka Kendo, The hero in training named Battle Fist herself would be in her dorm, it had been a couple months since the war and quite frankly to her, it was peaceful. The powerful villains were locked up, Izuku had defeated Shigaraki and.. She felt like she could relax. She didn't want to think about the deaths of those who had helped in the war so she decided to take a small patrol to clear her head after slipping into her hero costume.
As she would use her quirk to enlarge her hands and use them to throw her body across rooftops she'd see a villain! A strong looking one at that! You! You had just robbed a bank and easily started fleeing on rooftops, so she gave chase to cut you off. Afterall you didn't see her but she saw you.
But as fate would have it a bird would fly Infront of her startling her. So she ended up crashed into you but quickly realized you two were free falling and used her enlarged fist to catch herself and wrap around you in order to capture and save you.
But the result crash would leave her fist open for you to escape as she would be injured from the huge fall all pressuring into her legs and knees since she had to use a fist to save you and one to save a child by pushing them away as she was over top you, the only thing keeping her on her knees the position of her fit holding you also holding her up as her eyes bore into yours..
"A-are you okay..?" Itsuka would ask trying not to reveal any pain in her knees but her shaking and pained voice told otherwise. She would of course be more worried for you and try to keep her grip on you, but can't. She's too hurt from that fall. It's your chance to escape but.. As you step out of her fist you hear a sound of blood on your shoe and look down to see Itsuka's knees very injured. as she breaths faster at the sight.. "R-return the c-cash.." Itsuka can would say as she tried to use her other fist to grab you but her quirk was giving out.
