I will forever remember the time I was doing a cover with SONiKA and I wanted her (ah) phoneme to glitch on a note because I loved the idea of the sound there and I used every possible combination of factors (breaking note up, all the phonemes, weird parameter edits) and she just refused to glitch on that one note...
Now the info about hares surprises me. IIRC, hares are different than rabbits--hares have longer ears. I imagine they're probably pretty closely related, though.
I wonder if there's something in the lore about hares that suits the character better than rabbit....
