Man, the appeal of that pairing really is that built-in imbalance, isn't it? Kota sees this fragile, recovering girl and feels this overwhelming need to shelter her. Eri, who's been told her whole life her existence is a curse, gets this boy who treats her like a person, not a bomb. A lot of writers run with that protective dynamic, but honestly, the best fics flip it. Eri's power is terrifyingly potent; stories where she’s the one shielding Kota from a villain, even if she’s shaking, hit so much harder.
There's a ton of 'growing up together' stuff, soft domestic fluff where they have playdates at U.A. or Kota teaches Eri how to catch frogs. It’s cute, but I’ve seen a few darker takes that grab me more—like exploring the shared trauma of losing parental figures to villainy. They’d have this quiet understanding no one else could get, conversations held mostly in silence. The trope I can’t stand is when they age it up too fast into teen romance; it feels forced. Let them be weird, trauma-bonded kids who maybe hold hands under the table during a scary movie.
Yeah, it's definitely a niche ship. You don't get the tidal wave of content like for the big 'My Hero Academia' pairs, but what's there can be surprisingly thoughtful.
