As of this season:
SAO 2 - SHINON Q'w 'Q Especially looking forward to her interaction with Kirito after realizing his appearance was misleading (and after the cowboy scene)
Mahouka - still going, although given the time remaining I fear Yokohama arc is getting chopped to hell 'A ' like "does this scene have Tatsuya/Miyuki, no? cut" chopped...
Gekkan Shoujo Nozaki-kun - AHAHAHAHAHAHAHAHHAAH (read the manga before, and the anime is doing it justice)
Aldnoah Zero - Started cuz hearing about Urobutcher directing (at least the early parts of it) and stayed cuz Kalafina opening (and that it actually give personality to side characters), that nobody is afraid to kill is also a plus
Argevollen - Watched cuz it's basically the opposite of above in term of feeling to it (especially how much Susumu really need a good slapping, "WHY CAN'T I HIT HIM?!" MAYBE BECAUSE YOU SUCK)
Series still not sure if I want to pick up:
Blade Dance - read the novel already :v and frankly the fun part doesn't really start until the full party is assembled and some secrets revealed
Fate Kaleid - +Kuro, -Ilya....
