Answering here so as to not take over things!

But the basic deal is that using the wrong pronouns for people is considered incredibly disrespectful. It's referred to as Misgendering, and it's a very serious thing for the Trans community that is seen as very rude and offensive.

Even with fictional characters, it's a matter of respect. For example, you wouldn't call a fictional Black character the n-word because that's just not cool. In the same vein, misgendering a fictional trans character is likewise seen as Very Not Cool, since it shows a lack of respect to real people and their identities. It also tends to be very upsetting for them to see, since it's a ugly thing they deal with in real life.

Basically, it's better to use appropriate pronouns. Mutsuki uses masculine pronouns and wants to live as a dude. So should be treated as such.
