Overall, I gave this anime an 8/10. Contrary to many of the reviews giving a low rank to Last Period, I personally think quite a bit of thought went into the plot and gimmicks throughout the show. It genuinely did surprise me, because it is not the kind of humour I usually find in anime. It's been compared favourably to Konosuba, but I think the humour is entirely different. Konosuba's humour is character-driven. Here, the humour arises from puns and by characters breaking the 4th wall. For example, at one point they were referencing the Iphone v Android debate. Likewise, the show put in alot of effort into world-building and in changing the narrative style of the show. For example, in episode 5 they presented the whole show as a documentary. In episode 10 they attempted to make the characters self aware of the dating and clicker games they are a part of. It's fun, but it can kind of feel silly if the show takes itself too seriously, as it did in the last episode. The show works best when the characters are swept along by the cliches we have come to expect of the genre.
The major failing for this anime is that it has no sense of justice and does not feel complete. Characters behave horribly and put other people in danger and are seemingly forgiven by the end of the episode. The MCs just sigh and move on. Likewise, the major reason for the entire season i.e. the guild's treasure getting stolen, stands on shaky ground. Personally, when the explanation is finally given, I did not find it sufficiently convincing. We are never even introduced to the higher ups who put the MCs in this predicament. I think this show could have gone a bit further in delivering justice, while still keeping the light-hearted isekai charm. Nichijou, for example, can get quite violent, usually against Yuuko, but we generally accept that this is karma and move on with a laugh. This show can get quite frustrating to watch, as characters we are lead to empathize with are put in dangerous situations with the culprits getting away scot-free. Episode 10, while brilliant, did not receive a proper ending in my opinion, which was a bit disappointing.
The character designs are cute enough, and the world is well animated, but the music leaves a lot to be desired. There is nothing as striking as Konosuba's soundtrack here.
Generally, if you are a fan of self-aware comedy shows like The Office or Parks and Rec, and you play mobile games: You may like this.
