Mr. Elegance's Pronouns

Despite the honorific title of “Mr.”, I cannot seem to find a SINGLE instance of Mr. Elegance being cited with any pronoun to refer to them with. The closest I have found, is the pronoun of… we, which does NOT help in the slightest. I don't mean to cause any harm with these words in the SLIGHTEST, I can see exceptions to this case, but concerning the title of “Mr.”, is it fair to label them as “he/him”?

Unless there are pronouns I forgot to notice. In which case I shall cite them when I have the time.

Absolutely.

Mr. is male, Ms. is female, and Mx. is neutural.

Somebody could use Mr. and not male pronouns, but this is perhaps too unlikely to consider by default

"They call me Mr. Nonbinary. My pronouns are They/Them."
-Mr. Nonbinary

Mx. Nonbinary.

They call me Mrs Man. My Wife is Mr Woman.

And our child is Mx Both.

Both genders.
