^^ Now that I think about it, Kotomine Kirei:
1: Is seized by powerful urges that clash with a conservative background.
2: Has an extensive knowledge of the Bible precisely for the purpose of proving that it is bullshit.
3: Wants to top wife, but is so shy to say it that she literally kills herself out of impatience.
4: Simps for a golden bitch who is simultaneously the gayest and most homophobic person in town.
5: Gets a new hairdo to represent coming out, then refuses to leave house out of embarrassment.
6: Interacts with girls along the lines of "Hi, I'm-" -stabs, runs away, pretends nothing happened.
7: Excels at fleeing from powerful women.
8: Eats spicy food to feel something deep inside.
7: Wants to talk to the CEO of evil to figure out what the heck is up with life.
8: Dies duelling a redhead with swords in the mystical equivalent of a parking lot.
Ergo, Kotomine Kirei is the best portrayal of a lesbian character in all of fiction. Thank you for coming to my Ted Talk.
