at first sight this be yet another highschool anime with lot of excuse for fanservice and but there be a lot more go on . the fanservice be part of the plot and the main character be a tired cynic ( unusual ) and and most importantly there be a clever plot that tie all the episode together and and that pose some interesting question . the episode be deliberately non chronological and and it be certainly worth watch the series again in chronological order . the series be worth watch carefully and because there be a lot of casual hint in there that foreshadow and explain thing and plus a good number of in joke about other series and anime and other .
