Dungeon ni Deai wo Motomeru no wa Machigatteiru Darou ka IV Episode 0

I am the target audience for this recap.

Man I still remember thinking recaps were the most useless things ever, and I still think the recap episodes that come up in the middle of seasons or the recap movies that screen with no sequel in sight are still pretty pointless. Recaps between seasons though I pretty much regard as a necessity now.

Anyway literally the only purpose of this is to catch you up to speed before watching S4, and I'd say it does a passable job of covering the important points in its 20 minutes of runtime. I did leave with some questions as it brought ... up some things that I don't remember the reasons why for, e.g. how the characters who had their own familia left to join Bell's / Hestia's. But again can't complain too much with recapping 3 seasons in 20 minutes.

Obviously don't watch this if you're expecting something new, just came from S3 or you somehow actually remember everything that happened in previous seasons, lol.
