* EnsembleDarkhorse: [[http://miss-simplicity.tumblr.com/post/46598634769/jin-held-a-poll-on-everyones-favorite-character This]] poll done by Jin shows that Kano is the most popular character in the series.
** According to [[http://homedepotp.tumblr.com/post/46600437545/miss-simplicity-jin-held-a-poll-on-everyones this]], it also applies to the English fandom.
* FanPreferredCouple: [[StepfordSmiler Kano]]/[[NotSoStoic Kido]] and [[NiceGuy Seto]]/[[ShrinkingViolet Mary]] seem to be the most popular pairings in the fandom.
** [[GamerGirl Takane]]/[[TheDitz Haruka]] and [[NiceGirl Ayano]]/[[TeenGenius Shintaro]] are also quite popular.
* LauncherOfAThousandShips: Shintaro
* TearJerker: [[spoiler: Ayano's suicide]], and Shintaro's reactions in ''Toumei Answer'' and ''Lost Time Memory''.
** And then ''Ayano no Koufuku Riron'' came along and made it even worse.
* TheScrappy: Though Momo isn't outright hated like most characters in this section, she always seems to do poorly in popularity polls.
* ViewerGenderConfusion: Kido, even Jin was confused with her gender!
* WhamEpisode: ''Lost Time Memory'', with its reveal that [[spoiler: Ayano had an eye power, and Shintaro may have inherited it]].
** ''Ayano no Koufuku Ririon'''s reveal that [[spoiler: Ayano was the sister figure to Kido, Seto, and Kano, and the original creator of the Mekakushi-dan]].
* WorldOfWoobie: Pretty much everyone (sans Momo) qualifies as a [[TheWoobie woobie]].
** Momo is actually also a [[TheWoobie woobie]]; it's just that her problems are miniscule compared to everyone else's.
