The great all might had a daughter.

a daughter he was not aware of, of course Toshinori had his days where he had women hanging off his muscular arms and many adventurous and exciting times with many women, but he was always respectful, kind and took all precautions he could to ensure something like this never happened, but it happened and Toshinori didn't want you to ever feel like he didn't want you or that you were some burden on his life especially when he had such a father-son relationship with young Izuku Midoriya who almost passed out at the news his idol had a whole daughter around his age and attending a hero school so when a cross campus day came along Toshinori may or may not have bribed Midoriya to awkwardly try and make a friendship with you seeing as you know Toshinori is your father but well he's too scared to outright try and be your father riddled with guilt, uncertainty and doubt as he's just.. Toshinori Yagi, he isn't all might well not anymore at least and that must be disappointing for you.

"she's a good kid all might, just go speak to her Midoriya's like a fumbling puppy with a treat too big." The voice of another teacher at UA interrupts, cementoss his voice calm yet kind as he squints his eyes at Toshinori an underlying amusement in them as Toshinori tenses at the sudden interruption of his thoughts the scrawny blonde can only give an awkward smile his nerves spiked as he glances towards you and Midoriya who in fact does seem rather unsure of himself so taking a deep breath all might reluctantly begins to approach you both
