So Hibiki works as a substitute teacher, so I would be down for him being one of her students. She's also a big runner, and I think it would be cute if they end up having similar routes. But really she'll probably see a lot of the works hard/workaholic tendencies that she has in him, so get ready for her to worry a bit over him. Izuku, please take better care of yourself (says the hypocrite).

Or, if you're interested in the family angle, hers is pretty big. He could be a cousin or something! Which would give her even more reason to fuss over him.
