I guess I'm biased as a trans person but it's wild to me to see people suggesting that this isn't a trans story/is the opposite and about conforming to biology or whatever, cause like, this manga to me is the most trans feeling manga I have read, even more than manga that are explicitly about transness (like Wandering Son and To Strip The Flesh, both of which I love). But the way this manga uses its premise to explore Akira's trans feelings is, to me, second to none. Like I guess it's technically an allegory but it's really just the thing itself, it intimately understands the family pressures to be something you aren't, of repressing yourself to appease those people because you feel like you don't understand yourself just yet, the tepid slow exploration of gender and presentation, the inherent alienating feelings you get around others, the struggles of coming out and the fear of rejection for what you were, and the uncomfortableness with intimacy and attraction and what attraction even means. All of these things and more, I think Until I Become Me handles super well, and because of that, the story that it is telling is intrinsically trans.
