Izuku looked to the side as if searching for someone. If someone was observing carefully, they would realize that the black muscle shirt she was wearing was quite familiar. She had taken it from Kacchan's wardrobe out of curiosity. She wanted to know if she could pull off a muscle shirt, and Kacchan had the most significant collection of them. Although Izuku's chest wasn't as wide as Kacchan's, she still filled out the shirt nicely, displaying the muscles she had worked hard to gain.
Her abs were more visible through the thin material, and it was easy to see how toned her arms were. Even though she still wore her arm brace and her scars were exposed, it only enhanced her more masculine look. "If I'm lucky, Kacchan won't be too angry when he finds out his shirt's gone," she whispered to herself.
