it's not hard to estimate anime girls age tho?
in normal circumstances as jn without 800y/o loli bullshit it's very easy to estimate anime girls age
their facial features are pretty different and their body seem a bit heavier while their facial expressions give off a mature look even if it's "naughty" or not
and 99% of the time they come with huge boobies indicating their motherhood or feminity
but sometimes very rarely artists don't add these traits and it becomes harder to distinguish the age for example pic related
she has been stripped off of almost every characteristics i mentioned and she's been classified as a milf for age solely
another example would be >>2424247
she doesn't seem to have obvious traits either and is a milf based on canon
