The last words spoken in Re-Kan were literally "Yuri? Oh yes!"
So, with the season wrapping up, my impressions:
Owari no Seraph: Shit. Do not watch
Mikagura: Fun, gay. Supporting cast is kind of crap. Worth a look
Pleiades: Good tone, decent art, bad everything else. People around these parts are particularly unlikely to appreciate it, as the MC has good chemistry with a girl but ends up with a guy
Re-Kan: Passable? Large parts felt repetitive and dull, but it could be fairly good when it really tried. Also fairly gay when it really tried, but this showed up in the oddest places
Euphonium: Very well made, and I didn't like it. Yuri issues aside (which... I'll leave for other people to get into), it ultimately ended up being too dramatic and too unfocused for my tastes
Kekkai Sensen: Fucking awesome. Not yuri at all, though
