In Strike Witches, there's Yoshika's....shall we say, interesting... dream about Lynette, not to mention that Perrine clearly has a thing for Mio.
Don't forget the way Sanya always finds her way into Eila's bed after her night shift—and Sanya is in obvious adoration of Eila. "Doesn't it make your heart throb?" indeed.
Charlotte and Francesca seem awfully close, for that matter.
Let's not forget Minna's feelings for Mio, either.
Based on the events in Episode 8, Minna probably transferred her feelings for her old boyfriend (including concern for his safety) to Mio.
There's also a lot of Les Yay between Mio and Yoshika, what with Yoshika admiring Mio like crazy and Mio's mentor/Cool Big Sis role for Yoshika. The frequent Say My Name moments between them don't help.
And then of course theirs Gertrude and her sister Chris. I know some may argue that it's just a sisterly love, but given some of tone she takes in regards to talking about her little sister, plus the fact that their real life counterparts were married... I think it's safe to assume, (as a good number of Gertrude Fan's agree) that Trudey is a major sis-con.
