In perhaps the zaniest (though strangely lowest-budget) episode of K-On!! yet, we are formally introduced to Mio’s fan club – evidently a storyline in the manga that fans have long been hoping would be adapted this season (and which, I note, was the episode that most felt like reading a 4-koma manga to me.) I think it’s pretty obvious that the fan club is a played-straight parody of diehard otaku, and KyoAni being what they are, there is perhaps no one more qualified to write about otaku.
Which is why it’s very interesting to see that this is one of the most respectful portrayals of otaku (maybe the fact that the word is never used could even be considered respectful) that I’ve seen in anime, as well as a refreshing take on the age-old plot of a famous person dealing with fans that are more or less intruding on her life.
