He/She/It was never revealed.

But wouldn't it be fun if there was none? I'd be cool if they were a guild without any guild master at all, who decide things democratically and they only pretend to have a mysterious master who doesn't show herself to keep up the appearance of having what would be considered a nomral command structure to the outside.

Them being an all female guild is already raising some eyebrows, so they might have thought it to be a good idea to keep this under wraps for the time being and let people get used to one oddity at a time.

I don't truly beliefe that is the case, but it'd still be interesting.

But I guess we can at least savely rule out any conspiracy theories of Irene being the secret guild master, since MH fought aginst Alvarez with as much zeal as any other Fiore guild.
