There are people named Yuu, Mi and Ai. However:
- They likely didn’t choose their name.
- Their name only matches ONE pronoun they use, not ALL of a given person.
- Their first person and third person pronouns aren’t the same.
Think of the line “I am Gandalf, and Gandalf means me.” Ai would say “I am Ai, and Ai means me”, which sounds odd but hey ho. You would say “Drag is Drag, and Drag means drag”, which is borderline nonsense.
I wouldn’t.
In fact, I would try to deprogram anyone who thinks anyone should.
