To be fair, media where protagonists take care of and protect a child (aka the Lone Wolf and Cub trope) tends to attract these fans too though it's at the time were these lolicons are not as openly loud nor insane as it is now (especially with Diana being an appealing girl with blond hair and blue eyes not helping on the matter).
Apparently there are some fans that ended up not liking Diana once they learned that her voice actor was black.
I looked in my library trying to find games with this trope.
I found:
- Witcher 3 where you have Geralt and Ciri, the latter being a daughter, but not a child
- RE Village, where the protagonist literally runs around collecting pieces of his baby daughter, with the latter being more a McGuffin then a character. I think they made a DLC with her as a teen, but I don't own that
That's all I found in my library of ~150 games.
I now realise that my reaction to this game was so strong, because I was never really exposed to so many and vocal pedophiles, winking at each other and rubbing it in our noses, that this game "is for them".
Also, almost everyone running defence or openly lusting at this game, is a fucking anime avatar.
Another day, and more fuel for my burning hatred of weebshits.
