A new My Hero ship I like: Asui x Sero! Tsu is no-nonsense, Sero can handle nonsense pretty tamely, and they both have sass. They're like balls of sassy and worldly wisdom.
Side note: I could see them getting high once, it was too overwhelming for them and they never did it again.
Side-side note: I feel like they would retire from hero work earlier than the others to settle down.
Side-side-side note: They didn't like the sound of either of their first names with the maiden names of their spouse, so they decided to both keep their last names after marriage.
Sero could be a Feng-shui expert and learn decor for houses. Maybe even make tapestries as a hobby. Tsu would be a stay-at-home mom, but do a workout routine when Sero's watching the kids: their daughter, Jun, and their son, Akio.
Jun Asui (Quirk: Tape Depressant) - Jun can shoot tape out of her arms that can paralyze whoever they touch (like Tsu's toxic mucus). She dreams to become a tapestry weaver and make fashion out of it.
Akio Asui (Quirk: Glue Frog) - Akio can shoot globs of adhesive mucus from his hands that allows him to stick to walls. He can also high jump like Tsu. He doen't know what he wants to do when he's older yet, but he does know that Plamo (from Class 1B) is his favorite Pro Hero. He also inherited Tsu's big hands.
When the kids act up, Tsu's more heated with her strictness, while Sero is more chill with it. He can keep his cool with an angry child (he was friends with Bakugo, after all). Tsu wanted their daughter to have a sibling to bond with like her, but didn't want to have more than two kids to raise. She only ever took care of two siblings at a time (her brother and sister).
Headcannon: Their Aunt Satsuki is the fun aunt who does theme park fun, while their Uncle Samidare's idea of fun is thrills, extreme sports, haunted houses, etc. Tsu and Satsuki told the kids to call Samidare "Uncle Sammy", knowing that he hates it.
