Ooh, I love the dynamic angle + facial expression on this one

Hey, don't use your power for evil, Alex.

Lovely expression and idea in general. Honestly, wouldn't mind seeing more of Alex in general, to be honest.

Carthus Flame Arc is all I'm sayin

Nice lightning dance, Alex. Is this her initial skill level, or is this him after a bit of practice?

(What are the rules for Alex's pronouns anyways?)

Yeah this is most likely a bit later on in the story.

And I'm still kind of working on the plot and in essence the character itself. As it is right this moment, I'm leaning towards 'she' for Alexandria and 'he' for Alexander, but if I find a more nuanced way of representing "designated male by curse" I'm definitely interested in exploring it.

"Deman" instead of demon.
"Magical Dong Outbreak"
Dual wielding swords
Replacing sex pronouns with Dangly Parts or Jiggly Bits
Run away screaming, because impending lightning blast is more important than jibble type.

None of these are fairly nuanced.

There's certainly a large possibility space there!

For example, for some people, gender is a core element of their identity whether trans or cis; for others, it's not very important and they'll go with the flow.
So in one scenario Alex's conflict includes escaping a role that is not her; in another his conflict is simple unfamiliarity with the role. (And that's hardly exhaustive, even leaving species-related conflicts aside.)

Of interest too, your Korinatomy notes suggest that Korin and humans have differences in the way their gender roles are constructed. Alex would presumably have internalized human concepts of gender, but in Korin circles they might face a culture shock whichever role they tried to perform.

In an effort to avoid ruining the fun of the story on the chance that I ever get anywhere with it, I'll only say that you are absolutely right and things like this are under consideration. :)

I shall hope we're in a "get anywhere with it" timeline, then. :)
