For RO's, so far there is one non-binary character (the best friend), two male characters (cold bookish elf and tough vampire second-in-command) and one female (mercenary). We haven't met the last one yet (I don't think?).
The Vampire path seems the most accepting and welcoming of the MC so far. Quite the usual role reversal, I like that, though this definitely needs better proofreading, there's a few misspellings and grammar mistakes that I saw...
