I've watched four this season:

• Seven Spellblades: I assumed going in it would be fairly generic, but it's turned into my overall favorite, mostly on the merits of the story itself. It does a surprisingly good job of maintaining a relatively large ensemble of MCs. (Also, given that the setting is kind of "dark anime harry potter", I can't help but appreciate the implied "fuck you" to JKR in one subplot.)
• Helck: not all the humor lands for me, but enough does that I really enjoy the show! The slowly unfolding plot is kind of neat too.
• Undead Girl Murder Farce: I really like the sense of humor and style in this one. At the start it seems like it's going to be a bit like In/Spectre in terms of slow-paced mystery solving, but the action starts to pick up ~half way through the first cour.
• The vending machine iskei: I wouldn't say it's exactly a good show, but it's been watchable enough I made it to the end of the season!
