NO NO i love to ramble. i already play haru at prismatica, so going through changes is also something i've played with, which is why i was debating between a monster or a witch.

none of the larger/stronger monster options interested me that much for haru because i enjoy playing with her hang-ups as a small and weak prey animal, so her being fae or puca would mean i'd get to lean into that a bit more and have her work through familiar but more intensified instincts, but with fae having the bonus of wings. not that it would be putting her back to square one, but more like seeing how she'd move forward with it in a different scenario.

haru being a witch is what i was initially thinking about though for those exact reasons you mentioned! her being able to use magic and become a strong witch is definitely something she's not able to do in the game i currently play her in, nor in canon obviously, so it offers something unique and new. plus i could see her getting really into alchemy...as well as bonding with monsters on top of becoming a powerful magic user.

there was also just the initial, more shallow "hee hee tiny rabbit uses magic wearing witchy clothes"
