I don't have a whole lot of "must watch" shows this season (In truth, I let the season sneak up on me.)
Done a bunch of sampling so far:
Watch:
Mahoutsukai no Yome: More Elias and Chise! Also, lolwut Sleigh Beggy? You can even hear them taking the time to pronounce "Slay Vega"...
Kino no Tabi: Not much to see here, just a bunch of short stories through places that belong in SCP Foundation Custody.
Net-juu no Susume: The pilot looks adorable. Moar!
UQ Holder!: Needs more Chisame. Kirie works as a substitute, but there's no substitute for the original Riajuu otaku.
Sangatsu no Lion: I missed this show.
Maybe:
Konohana Kitan: I remember this Manga! Good source of adorableness for those of us needing to wean off New Game!!.
Black Clover: Look, It's Natsu and Zeref!
Two Car: Seems interesting, but has a lot of characters to establish, from the look of the first ep so far. Not sure what to make of it. I guess the chara variety will be handy for art reference, but it makes me wish there was more Ao no Kanata no Four Rhythm.
Kujira no Kora wa Sajou ni Utau: This one looks interesting, waiting for first ep subs.
Shoujo Shuumatsu Ryokou: ...Fallout with Lolis? Did one of the Fallout games make it to Japan recently?
Dropped before the end of the first episode:
Chuuni Taisen: This series is trying to rip off Fate without relatable characters. Has a literal bunny ears rule lawyer necromancer.
Stuff I'm just skipping:
Kouseki no Kuni: How on earth did this get an Anime? It made no sense as a Manga. Was it from an LN or a game or something?
