Unclear would probably be the best option since it is unclear. But Male would surely be the correct choice, because he's male from any point of view we've seen so far from my understanding.

But I'd prefer if we left it as unclear. I'm sure Mutsuki's gender will be touched upon later in the series either way, and if it it isn't, unclear would be the best choice, because it has yet to be clarified.
