Characters that would only have kids from unplanned pregnancies:
Kenma Kozume:
He definitely never has and never will plan for kids. It's just never something he thought about seriously and being a father was never something he had an overwhelming desire to be.
However, he's lazy. He's already running a company and streaming so other times he just wants to be lazy.
Add in the fact that I headcannon that he has a lower sex drive and is on the ace spectrum (the two are not one in the same coming from someone who's on the ace spectrum) when he's in the mood he takes advantage of it.
So if you guys are in the thick of it and the condoms are in the other room or your out he's not about to go get some or stop unless you're very insistent.
Also you definitely asked him to go buy a box of condoms on his way home and he just didn't feel like it.
Anyway, you guys go without condoms a few times cause no way your gonna get pregnant after three rounds without.
Except you do.
When you tell him man just buffers for a moment like 😐 but he probably comes around the quickest. At first he's worried because he has trouble taking care of himself but if he can manage all his work he can manage a baby...right? Your already knocked up not like he can change it.
He ends loving your kid and being a dad. You might even be able to convince him to have a second, but afterwards he's not making the same mistake again.
My man books a vasectomy after.
Shouta Aizawa:
He already deals with a bunch of kids on the daily and he's a hero. So, kids were never in the cards for him as far as he was concerned.
However, like Kenma he has a lower sex drive and is on the ace spectrum. So, sometimes he's not even aware if your out of condoms or where you guys last put them.
So if you guys are in the middle of it and can't find the condoms your both like whatever it's just once.
But in a classic fan fic moment you get knocked up from having sex once without a condom.
At first Aizawa has a moment were he's like of course this happens to me. Then he's kinda quite and contemplates how the fuck he's gonna make it work, but he gets his shit together and makes it work.
He loves being a dad and works hard to do his best.
But, he's not having another one. He loves his kid, but he definitely gets a vasectomy before their first birthday.
Shoto Todoroki:
He would never willingly continue the Todoroki bloodline.
Like the other two he's on the ace spectrum. It's not really relevant but I wanted to mention it.
However, this man loves creampies. So, if you're out of condoms he'd purposefully not buy them for a couple days.
Not like one weekend of unprotected sex is gonna get you pregnant right?
Wrong, he knocks you up.
He freaks out the most. He has daddy and mommy issues so he never had a good example. He has a pessimistic, this child is doomed mentality. He probably stays somewhere else for awhile to figure his shit out.
It takes him a while to come around and he honestly doesn't fully until your kid is born. He sees and holds your kid for the first time and just has this moment.
He loves and adores your kid and now that he has the one you could definitely get him to have more. He loves being a dad even though he never thought he would be one.
Just some thoughts that invaded me. I saw an old show, The Secret Life of the American Teenager, on Hulu. It's basically this teenager goes to band camp her summer before high school, has sex once, and gets pregnant. This got me thinking about accidental pregnancies and now we're here. I don't think these characters would ever plan to have kids and probably never had an overwhelming desire to be dads. But, they're the types to think an accidental pregnancy would never happen to them, would go without condoms, and then knock you up.
