Inspired by comments from 10 Most Rewatchable Shonen Anime Series, Ranked
Here are a few examples that I know of:
| title | expected | actual |
|---|---|---|
| Frieren | non-shounen (seinen?) | shounen |
| Attack on Titan | seinen | shounen |
| The Apothecary Diaries | shoujo | seinen |
| Umamusume: Cinderella Gray | shounen | seinen |
| 100 Girlfriends | shounen | seinen |
What are other instances of misidentified demographic you have seen?
Quick and dirty definitions of anime demographics:
- shoujo - girls
- shounen - boys
- josei - ladies
- seinen - men


It’s both. It’s telling you “hey, if you’re a teenage boy you’re more likely to like this.” It’s also telling you that the writing is less likely to be difficult to read or understand. Once you’re familiar with what gets published for these demographics it tells you all sorts of things, really.
