Oh hey, thanks for the suggestion! :D Cal begins as transmasc / winds up kind of remaining solidly nonbinary by the end but I could see Karakos being read as transfem (even if also edges more on the nonbinary side too at the end of it) since they don't go back to being men/masc at the very end.
If that fits what your outlines for this collection are, then yeah I'd love for it to be included!! But no worries if it's not exactly the kind of story/characters you're looking to include :>
