This author sure does have one tempo and they do comit to it
I mean bookmark too but it would be nice to see it evolve a little
In their defense, evolution tends to come in repeated iterations of the same thing with a small difference getting emphasized over a long period of time. It isn't what Pokemon has poisoned a generation to think of the word as.
So what's the difference being emphasized this time around? The protagonist is
way more assertive, likes their new form and there's no sure way to undo it. Karii had to answer to someone who could force her back into male form and in fact did so at one point on behalf of the transphobic* best friend. Magical Trans had an undercurrent of shame culture hanging over it -- that fantasy worlds do not goes a long way to explain why so many manga take place in them.
(*I'm not using the term here to mean hateful/bigoted but literally in the sense of expressing hostile aversion or discomfort towards someone being gender subversive. That can eventually become hate over time though.)
