How do you think they will develop Umiri's character? So far she's presented as a supportive but detached professional. How would it fit with Timoris' "not afraid of being afraid"? Might Umiri's fear have to do with being a leader and active in the creative process as opposed to being a hired gun playing the parts put in front of her? My background as a musician that has been that hides gun definitely makes me wonder how they might explore her character and also why she's my favorite in Ave Mujica so far. Also her gloves, her gloves are cool and yabai...just saying.
Umiri's character could really go in any direction. In regards to how I think the characters will be developed I honestly don't really have an answer, because I think it's far more interesting to be surprised by how the show will do it than make up my own preconceptions of what they will do and be wrong. That's just me though! and I think it's fine if others do speculate. All of that said the way I read Timoris as applying to Umiri's character I think lies in how she 1. wants to be seen (she gets visibly hurt when Taki says she doesn't "need" her) and 2. that part of her that spectates and watches over a situation from the side, and isn't afraid (!) to get her hands dirty. She has that kind of quiet, firey passion that's almost scary.
