How about K1-B0, Kokichi and Ryoma with a Ultimate Sukeban (Female Delinquent) S/O? Like, she's rude and cold with everyone but the boys? 👀💖
I had fun writing this one, I hope it’s okay! -Mod Kirumi
“Why do you not come to school? Don’t you worrry about your grades?”
But he’s supportive! Unless you start failing classes, then he steps in.
He thinks your tough guy side is a bit frightening, but he also really admires it.
As much as he loves you, he won’t ride your motorcycle.
“S/O! Stop that, you’re going to get in trouble!”
You look back at him, away from the jerk who insulted him. Your scary expression has been replaced with a blushy smile.
“Don’t worry about it!” You chirp, then turn back to the teen, picking him up by his collar. “Now. Apologize.”
He thinks you’re so cool.
Kokichi demands to ride your motorcycle.
You’re basically his chauffeur now, congratulations.
He thinks your ‘angry face’ is adorable. 
Definitely makes fun of your sweet side every time you show it.
100% on board with you beating up (or at least threatening to) anyone who disses his organization.
“Nishishi, you shouldn’t have messed with my organization! Now you’ll have to face our Enforcer!”
You come in, a wooden sword balanced on your shoulder and a brown paper bag in your hands.
“Kokichi, you forgot your lunch again!” You chirp, passing him his lunch before cracking your knuckles and turning to the man with a dangerous smirk. “And who are you?”
You intimidated him at first. You weren’t like most gang members he had met, you weren’t all talk.
But after a while, he started to warm up to you.
Loves riding with you on your motorcycle, though it embarrasses him to admit it.
Doesn’t exactly like you solving all your problems with violence (he’s afraid you’ll run into trouble with the law), but he respects you for standing up for yourself.
The first time you showed your sweet side it caught him so off-guard he stumbled as he walked and almost hit the pavement.
It’s a bit embarrassing when people who make fun of his height are suddenly pinned against the wall.
“Really, s/o, you can let him go. It’s fine.” You turn back to your boyfriend with a winning smile.
“Don’t worry, hun! I’ve almost squeezed the apology out of him!”
Ryoma let out a small sigh and a soft smile as he grabbed your shopping cart. “Alright, I’ll go check out. Just be careful.”
