Just becuase, well, since we might be finding out here soon, I'll just put my guess in that Raiden is a female too.
I have to admit I've run into this circumstance once. My car broke down on a busy street and I couldn't get a hold of anyone, and this couple came by and offered me a lift. I wasn't sure if they were lesbians or not or if one of them was a guy. If it was a guy, he kind of had a high voice and he wasn't very big. I was very self conscious about the whole thing, I was waiting for some clue to help me out. But they were very nice, I wanted to give them some sort of thanks for helping me. I think the one even had a name that could go either way. To this day, I am still clueless as to what they were.
Of course, I get a few of those kind of people through my checkout everyonce in a while. I generally try to see on a check or credit card or something. I hate it because sometimes I'll say "hello sir," and then I get a closer look and it's a woman, or vice versa. Gads, how embarrassing! To save myself any trouble I try to leave out any gender referencing.
Anybody else ever experience this kind of problem before?
