About Suo's master

So I was wanting to ask this for a while but do y'all think Suo's master is a female?? Not only would it explain some of Suo's habit( he sometimes has the patience of a saint istg-) but it would be really cool as well cause then they'd be the first female in WBK who can fight!! ( The others are cool as well esp Kotoha but still)

So what r your thoughts???
