Akira's situation early on is like very rough because he has kind of an immediate transmasc dysphoria reaction which sets the expectations for his family to try support him by considering him a boy at heart, and then that expectation never gets corrected when Akira might be questioning it. This coupled with forcing them to socially conform to being a girl in public regardless is a severely messed up situation that I don't think anyone would envy.
Over time Akira finds they want to try feminine things and like looking cute, which does align with the expectations of the gender she socially presents as, but conflicts with what she thinks she should want, especially considering what her family expects of her. This culminates in the kind of trans experience that a cis person might not consider as trans: someone presents as the gender they want to, but feel immense guilt and shame from doing so. This is actually an extremely trans experience because of the gendered expectations society impresses into people, that still subconsciously remain even when it conflicts with presenting the way the want.
What could also trip people up is Akira's internal use of pronouns still seem to be "ore", translated as "I(M)". I think that's a p interesting habit to have kept up. Especially because, in this volume, now that she's shared her secret with her two friends, she's starting to actually use "ore" around her friends when in private. She felt comfortable enough to accidentally do it in public in ch69 and then started fumbling to correct herself. This newfound comfort around friends where she can feel like she can truly not hold back is actually bringing out a lot of her boyish interests in mannerisms. Which makes sense, on the other part of the gender spectrum she's had to socially suppress the parts of herself that could be seen as boyish. It's because of these two forces that's lead her into showing a big interest in behaviors and hobbies not being locked to any one gender.
This is sort of pointing me towards Akira's final form probably being a combination of feminine and masculine traits that she has the agency to choose. Despite the title, I think the persistence of "ore" might actually point to her eventually becoming mainly an orekko, although obviously she never has to choose just one personal pronoun.
Also, lmao, I'm like 2 weeks late to the discussion, but reading it wanted me to put all my thoughts in order.
