Which My Hero Academia Fanfiction Explore Eri’S Feelings When She Calls Izuku Papa?

Honestly, most of the ones I've stumbled across handle it pretty poorly—it's either instant domestic fluff with zero trauma or weirdly OOC where Izuku has a full-on breakdown. The few decent ones frame it as a verbal stumble she doesn't even fully understand. Eri's not exactly versed in normal family terms, so the word 'papa' might just be a sound she associates with safety, not a conscious label. I remember one short fic where she overhears another kid say it and repeats it experimentally, and Izuku's quiet 'yeah?' response makes her feel like she's done something good. That subtlety worked. Mostly, though, you have to wade through a lot of overly sentimental stuff to find the fics that treat her perspective with any complexity.

Found one called 'Weight of a Feather' that gets into it pretty well. It's not the main focus, more like a slow-burn family dynamic story where Eri's living with Midoriya after the Overhaul stuff. The 'Papa' moment happens after like 15 chapters, and it's less a huge dramatic scene and more her just slipping up because she's half-asleep after a nightmare. What I liked was how it dealt with Izuku's internal panic—not in a 'oh no I'm too young' way, but in this overwhelming sense of responsibility he feels he hasn't earned. The story spends a lot of time on Eri's confusion about what a 'dad' even is supposed to do, since her frame of reference is basically non-existent. She calls Aizawa 'Uncle Shouta' in the same fic, which creates this funny little tension because he's technically more of a guardian figure but she assigns these labels based on who makes her feel safe in different ways. Sometimes fics make the moment super saccharine, but this one played it with a quiet awkwardness that felt more real. The aftermath has Izuku overthinking every interaction, worrying he's going to mess up her healing by not being parental enough, while Eri is just cautiously testing the boundaries of this new word. It's less about the warm fuzzies and more about the weight of the title for both of them.

Another angle I've seen is in time-travel fics, where an older Izuku comes back and basically adopts her proactively. In those, the 'Papa' thing is often a reward he's been working toward, and Eri's feelings are portrayed as a mix of profound relief and finally having a anchor point. Those can feel a bit more wish-fulfillment, but they're satisfying if you're into the found-family trope done explicitly. There's one where she starts calling him 'Papa' after he literally fights a villain who tries to take her, and it's her way of claiming him back. Her feelings there are tied up with possession and safety in a way that's maybe not super psychologically nuanced, but it hits an emotional beat that works for the story's pace. I tend to prefer the slower, messier explorations over the destined-family narratives, but both have their place depending on your mood.
