I would like to suggest a character if you don't mind. I would like to suggest Hibiki Shikyoin from PriPara/Pretty Series. According to the producer of PriPara, she identifies as neither female nor male, which means she is nonbinary. Plus, she likes deceiving people into thinking that she's either female or male. She also admires Fuwari and calls her "My Princess", which may imply that she's queer or lesbian.
