Toshinori Yagi/All Might:

You didn't even have time to process as he suddenly ran away, punched the villain so hard they passed out then was back at your side, happily asking what you two were talking about. As you both continued talking, he called the cops to come pick this villain up.

Shota Aizwawa/Eraser Head:

He will just sigh, not in the mood for this. He didn't even want to go on this date since he isn't really a person for dates, he rather just cuddle on the sofa and watch a movie or read a book and call that a date, not go out to eat and try to make forced conversations. He will tell you to wait a bit before he walked away to go deal with the villain. He took care of it very quickly then returned, asking if you two can go home now.

Hizashi Yamda/Present Mic:

When a loud explosion went, he let out a "huh?", quickly turning around, his glasses almost flying off with how quickly he turned before he groaned and slouched. He wasn't in the mood for this and he was on a fun date, so he leaned to you, asking in a whisper if you think you two can just sneak away and leave it to another pro-hero. When you gave him unimpressed eyes, he groaned but said fine and walked away to go deal with the person, clearing his throat, getting ready.

Nemuri Kayama/Midnight:

She gasped, not out of shock but offense before she angrily asked who dared to interrupt her date. So she stormed out, using her Quirk to put the villain to sleep before she tied their ankles and wrists up, called the cops then returned, happily saying you can both continue now.

Keigo Takami/Hawks:

He will pout, saying he was having so much fun before he sighed and told you to wait a bit. He hurried away and dealt with it quickly so he can quickly return and continue the date. When he returned, he happily continued what you two were talking about, acting as if that villain didn't interrupt the date.
