It seems that, Asakawa Yuu. Seiyuu known by giving voice to characters like Fate's Rider/Medusa, Love Hina's Motoko Aoyama, Azumanga Daioh's Sakaki, Vocaloid's Luca, Senran Kagura's Daidouji among other; might be getting married to her friend of many years Mizuna Rei.
A couple of days ago she posted this on her personal blog
Good evening
A few days ago, I spent the day with Rei Mizuna (again).
There was a moment when we were trying to decide who would take a bath first when we though, why don't we just go in together?
And so, we had a bathtub party.
We talked about about everything, from big issues/problems to meaningless fluff. The hours just flew by.
We weren't shrieking like girls in the way you guys would anticipate. Not at all.
Like a long-time married couple, we just got changed and got into the bath normally.
Or rather, I really want us to be family.
Next month, a premarital trip is planned.

They've spent a lot of time together (they spend the last two christmas together for example) and Asakawa has been vocal about being open to the idea of dating a girl so it doesn't come from nowhere. Of course, it exists the possibility of all of this being a PR stunt, Asakawa posting drunk or a simple joke. But if the situation is indeed real, it would be something very special since it would make Asakawa the first Seiyuu to actually be in a gay marriage.
