She's French, but does read English. As for slash.... She knows Yann since much longer than I do, and did read Les Récifs, so I guess some slash (nor even the rest) won't frighten her. ;-)
As for gay stuff, I'm pretty sure it's with her that I went to see that Thai (?) film about a national volleyball team whose members were all either gays or transvestites (based on a true story).
And she is a manga/anime fan.

So, gay, checked. Slash, checked. Cowboy Bepop, checked. Ok, everything's fine. ;-)
