What would happen if those two fucked?
It's a nonsensical sequel that destroy every meaning Eva had besides selling toys and obviously Anno is using it for funding the projects he really care about. Besides, Kawoshin is utterly destroyed. The fujos might love 3.0 but Kaworu is a manipulative retard
Is it really fujo if they both look like girls?
Shinji is now canonically a girl, so it's perfectly heterosexual to want them to fuck.
Fujo's often like crossdressing more than guys do, gay or straight.
Probably because it fits into the uke and seme thing pretty well, and fujos eat that shit up. Gays at least in Japan usually like more realistic relationships between men which happens in bara stuff.
