The new season begins this week, here's what I've watched so far:
Shougeki no Souma: Kid makes amazing food, people orgasm while they eat it. He gets sent to a cooking school after his dad closes their restaurant, and things go from there. It's a culinary battle shounen and the manga's a lot of fun.
Plastic Memories: Super-lifelike androids with a lifespan of about 9 years have been created, and are impossible to tell from humans. The MC works at a reclamation service with other humans and androids, who must collect androids at the end of their lifespan. A good mix of comedy and tragedy, already teared up in the first episode. Could be one of the best of the season.
DanMachi: MC is employed by a Goddess to clear dungeon floors for her glory and his livelihood. He's also the only one who works for her, so it's slow going until his Goddess discovers his potential for super-growth of "stats" as he gains experience. Mostly a comedy, I think it's based off an LN/manga as well.
Rei-Kan!: Girl can see spirits, SoL comedy dealing with that and how her friends and relatives handle her "gift."
Yahari Rom-Com s2: If you liked the first season, this is shaping up to be just as good, I think.
Got a couple more to watch still, including the new Haruhi series focusing on the alternate universe version of Yuki Nagato from the movie.
