In terms of MyGO/Ave Mujica foil relationship, it's funny I've never seen anyone point out the one between Raana and Umiri.
In a way, it makes sense, since they don’t interact together at all but I think they are both built on a similar idea; really competent but detached musicians learning to love their bands. They are both girls that deeply love music and (more or less consciously) search for a place where they belong and can do it with other people. Raana has a more free spirited approach to it while Umiri masks it under a veneer of work for hire professionalism.
But in essence, I think they share a common core, except Raana kind gets the best case scenario and Umiri the worst one, in a way that talk about what we could call the autistic fantasy of “what if I was so good at something that people would accept me even if I’m shit at sociability”.
To keep it short, Raana’s arc pretty much run with the idea. She’s really good with the guitar so the interesting girls let her be a little gremlin and pay her matcha parfait and sure, she have to learn to get a bit less impulsive but Taki go an extra miles to try to integrate her to the band and in the end she get a place to be herself and be a part of team mostly by sticking around and people accommodating her.
Umiri’s arc, meanwhile, is kind of what happens when this kind of thing doesn’t work. Umiri played in about thirty bands at the beginning so she never gets to feel alone and she has a professional attitude that makes her easier to work with than the stray cat. If Raana is a beast of music, full of passion; Umiri feels like a girl that has tuned herself in an instrument, in the hope it makes people want to use her. And it does work until it doesn’t, with Taki’s words and the last concert of Crychic making her realise that; “hey, wait ! She wants that too actually !”. So she tries to open up and help rebuild the band, to prove that she can give a shit, that she’s “trustworthy”… And she’s absolutely cringe doing it. She’s awkward and trying too hard and everyone else is too stuck in their own shit to pay attention.
And while Raana was the one who stuck with Tomori and helped her keep the band afloat, Umiri barely had anything to do with Ave Mujica getting back together. At the end, she is still the one with the least connection, barely involved in the clusterfuck of codependency that has become her band.
I don’t know, if it really makes sense, I do think they can be seen as the two poles of the desire of being accepted simply by being yourself / the fear that even if you try your best, you won’t really belong.
