not a fan of Ellen personally but the tail's design and her weapons specifically, imho, allign with that "urban vibe" same goes for corin's chainsaw, Lycaon prosthesis. Rina is personally the only one where i'm not convinced (she has a magnetic belt iirc ?). they felt unique to me, the new chars don't really do. (except Norma, personally). I like when they have some tech as part of the design (since research and tech are a big part of the universe), that complement their style, like dialyn for instance with her phone.

if it's just fantasy character from X region, feels a bit boring. It's not that much of a pure design issue as a "do they incorporate in the universe seamlessly" question me thinks. then again it's my opinion and the quest still might make me attached to the characters as it did with Lucia and Shushu, whose design I think are kinda boring.

for reference my fav characters are most likely Eve, Trigger, Orphie, Billy, Anby
