Chapter Text
-They'd have 3 kids. A pair of twins and a younger one by four years (they have these kids through adoption, surrogate, or mpreg - idk whatever y'all prefer)
-The twins: Akio and Hiroko, the youngest: Isamu (I like to think they sorta named him after Izuku?)
-Akio is technically the oldest (by 30 minutes) which he loves to shove in his twin sister's face constantly. And he takes the oldest sibling/brother thing very seriously. He acts as the protective brother and all that. And he's proud of that self-proclaimed title!
-He's incredibly nice and sociable. He's energetic and bubbly. It causes people such whiplash cause where did he get that personality?? I like to imagine him as the talker of the family.
-Hiroko has Shouto's aloof personality, but Katsuki's temper. She has a ton of descriptive threats that are said in a monotone. Terrifying.
-However, she's pretty chill - respectively. She's chill until somebody gets on her nerves and she doesn't have much patience. So take that as you will.
-Has Katsuki's glare and Shouto's eye roll mastered.
-She's an introvert, but Akio pushes her out of her comfort zone a lot since he's an extrovert.
-Isamu is the most chill out of his siblings. Also the quietest.
-He's very smart and he prefers to keep to himself and read, etc. This makes him a bit standoffish.
-A lot of things go over his head. He has trouble understanding social interactions because he's so reluctant to interact with kids his age.
-The family collectively babies Isamu. And he lets them.
-Okay let's talk dynamics between the kids and todobaku!!!!
-Shouto and Katsuki are the best parents ever!!!!!!! Sorry, I don't make the rules.
-The kids definitely have "their parents". So Akio and Katsuki tend to be closer. Hiroko and Shouto tend to be closer. Isamu gets the best of both worlds.
-Akio and Katsuki are besties. At least, Akio constantly exclaims that to the world. And he enjoys bragging to everyone that he's best friends with Pro-Hero Dynamite.
-They cook together all the time. So Akio is the best cook out of his siblings.
-They're always roughhousing. Akio initiates the majority of it.
-They fight for Shouto's attention all the time. Akio usually wins which makes Katsuki all salty.
-Although Hiroko and Katsuki aren't the closest, they have their moments.
-They honestly just validate each other's anger because they have the same pet peeves.
-Hiroko does tend to go to Katsuki for advice and stuff like that. So there's a great level of trust between them.
-They have fun little screaming matches <3 It's nothing serious. They argue over the most trivial things. And it's not even arguing. They just talk 10 decibels above the amount a normal person would.
-Katsuki is actually quiet when he's with Isamu. Isamu greatly appreciates it.
-Isa's favorite thing to do with his dad is read. Especially when Katsuki reads to him!
-As much as Akio enjoys hanging out with Katsuki, he also likes his quiet time with Shouto.
-Christmas fanatics, dude. They're obsessed. You can imagine Shouto's joy, somebody who loves Christmas, when his son began to share the same excitement cause Katsuki never enjoyed the holiday.
-Akio will throw - chuck Katsuki under the bus if it means he'll get attention from Shouto.
-Hiroko and Shouto spend a ton of time together. They'll just talk or do whatever.
-They're both generally non-talkative, but together, they talk quite a lot.
-They gossip a ton.
-Isamu and Shout enjoy each other's presence. They rarely talk because being near each other is satisfying enough.
-They're always taking a nap. Like how can they sleep that much?
-They both love cats. Poor Katsuki having to say no to Isa and Shouto about getting a hoard of cats.
