>>57013946Diona is a teen in her rebellious phase. She is old enough to have an actual job handling drunkards and large quantities of alcohol unsupervised, of all thing.
iirc she is at least 15 from backstory elements, meaning she is closer to Fischl in age than to Klee.
She is just really fucking retarded and small. No idea if that's due to her being a catgirl, and if her race's age should be re-scaled or something.
Not that it matter much, I just put semi-arbitrary cutoff because some Anons complains when a loli isn't a "true" loli.
Sigewinne should also probably go in the 500years category, but she is just a sea slug pretending to be a human so... eh.
I also forgot Sayu, who is another contender for the "midget teen or actual kid" question.
