Nami has talked a lot about guys she finds hot, I remember some old tweet that was something like, "I used to be into white guys, but now I'm into asian guys" (

)(kaworu awakened this, I'm sure), where-as any talk about girls is generally the more 'girls liking cute stuff' vibe. And I forget the name, but she's friends with some lesbian iPhone hacker, and I think that girl said she was straight?
Although I suppose being attracted to androgynous asian men is ~75% of the way to being lesbian...
Edit: I went looking for what I was remembering. Someone asked the lesbian hacker girl, "What would a date with namirin look like?"

Also apparently this girl works with (or is just a fan of) the company that made 'Please Be Happy' that Dottovu was in, and apparently all of their stuff is explicitly yuri (not like, 'explicit', but literally "stated clearly and in detail, leaving no room for confusion or doubt")
