“I combined the post for the last three [two] episodes of [K-On!!] for artistic and narrative purposes, not because of laziness.” ~ If you don’t learn from the best, then you’ll never become a great anime reviewer.
For the most part, “Extra Episodes” are like throw away episodes: You don’t expect anything important or impactful from them. For the most part, Episode 25 and 26 were just that. But behind all the silliness, there were a few moments in these final episodes that proved to be important in providing closure for all who love K-On.
