i think she is initially team kaz cus he just exudes like... reliable shounen lead energy? so the two just vibe well with the other and be bros. but she thinks shiro is very cute and fully supports/respects his relationship with kazuki! she protects these boys with her big axe and sword 🥰❤️

this is a boring answer but i think she likes both! she is very puppygirl-coded but to her, both cats and dogs are cute and charming in their own ways.

now that i think about it, i don't think violet has been on enough dates (shitty or otherwise) to really have an "ideal" one? even with haurchefant, much of their relationship was comprised of stolen moments and impromptu visits between missions.

as for favorite desserts, i think violet likes those roll cakes with cream and fruit in them! to her, it's both fancy and delicious without being too heavy 🍰🍮

she does not! i imagine it wasn't a part of the viera customs and truth be told, i also didn't think about it
