Gender Weirdness, plural
Pronouns are tough when you're a genderfucked multiple system.
Tohri uses He/him out of like... Relative Position. Even though he's more of a 60/40 split.
Kerithe is a Woman and identifies as She/Her but has been (having to) embrace her more masculine aspects. So more of an 80/20 split.
And Yaori is a She out of like... Simplicity. Shi/Hir is more accurate but not really enough to matter.
And that's all leaving Alone sexualities.
