Season 2 though?
It's kind of a disappointing follow up to be honest. Apart from arguably being even more educational about history, this season really wasn't as interesting or exciting to watch due to it pretty much lacking what made season 1 good in the first place. Unlike the first season, the stakes of the missions here were almost non-existent in comparison and also didn't have any of the harder hitting moments like the best episodes of season 1 did (with the exception somewhat being the story of the rogue agent in episode 6). Even bringing up the more fun than serious aspects, season 2 doesn't really deliver on that front either as the more laidback episodes of the previous season had a much better sense of creativity and fun than this one did.
The final episode wasn't bad although unfortunately a bit predictable in the end and the ending was fine but pretty average as well. The best compliment that can probably be given to this season is Yumiko. She was pretty likable and being more similar in personality to Bon made their dynamic together more fun to watch than Ream with Bon. However, by the end she ultimately wasn't as well written or memorable as a character as Ream and also obviously didn't have nearly as large an effect on Bon as a character.
I don't outright not recommend watching this season as some will likely still enjoy it just as much as the last one, but if I were to have any possible rewatches in future it'll personally definitely be for just the first season only.
