It’s hard to live up to expectations after Frieren but here are some that were memorable for me:

• Fate Zero - it’s a battle royal with magic, the story isn’t the focus but the characters and fights are great
• Spice and Wolf - this is about a merchant’s journey with an unusual companion (there is a new (re)adaptation coming next season, but the old version is also quite good)
• A Certain Scientific Railgun - a sci-fi city and it’s secrets, I think it does well in the would building

Many are already mentioned but there is a lack of SoL and KyoAni shows so these are what I missed:

• Shirobako
• Hibike! Euphonium
• Hyouka
• Hanasaku Iroha

The sequels look promising but aside from them it seems to be a slower season.
