@Banana Chloromance? Not sure what that implies. What is it?
One the big reasons I kinda gave up on Miyu joining the "raah, power up" arc plot that a bunch of characters have was because.. When I pitched my ideas for my other characters getting power ups that fit their personality, the gms completely ignored me, which I took as consent. When I pitched it for Miyu, they went "Oh yeah, you could learn that from X" and I went "So, someone else already has all the powers I wanted to develop? Miyu wouldn't be adding anything unique?"
I thought I had a unique vision for "Unity" style upgrades, but apparently some other angel somewhere has all those powers. Which means if Heaven ever actually genuinely needed Miyu's powers, they have someone else who has all the same powers.
My current plan for Miyu's Arc is "Figure out a way to get with Henry", which, if we both join team Grafdakka, will probably happen.
