this is going to be moved to a diff rentry at somepoint
basically yes the mascots that go with the crypton voicebanks do have canon ages this on multiple crypton official sites and miku herself even has been referred to as 16 by crypton officials multiple times
i am not saying songs like rabbit hole and such are wrong or that those versions of miku cannot be sexualized I'm saying that the default box versions of the cryptonloids (except meikai obvi) that have official ages are in-fact canon and if you sexualize those versions of the characters dnf/i (also dnf/i if you ship box mikuluka bc thats a 16 and 20 year old)
many many vocaloids have canon ages and some even do have lore to them if you deny that then youre just factually wrong as miku being depicted as a CHARACTER behind the voice is what made her and vocaloid as a whole popular outside of music prods
(note that kaito and meikos box arts were not considered characters behind the voices when they first came out. they were just that. box arts. they didnt become crypton 'characters' until after the success of miku.)
