* AlternativeCharacterInterpretation:
** Chitanda suffers from some sort of neurological disorder that affects her memory and prevents her from maturing beyond the mentality of a four year old.
** Irisu is emotionally crippled due to being the heir to her family's business, meaning she has to shoulder the burden of running a company before she even graduates from school. The result is that she can't really make any meaningful relationships and comes off as a ManipulativeBitch. She is also secretly jealous of Chitanda's childlike innocence, as she represents the childhood she always wanted but can never have.
* SugarWiki/AwesomeArt: It's Creator/KyotoAnimation, [[http://www.youtube.com/watch?v=pKX3JPjKj5s&list=UUsvcxby9YSHl3i-eNu51kEQ&index=1&feature=plcp after all]].
* BrokenBase: Opinion on the ending of the anime is split between those fans who thought it ended on a logical and satisfying note to those who were disappointed that none of the [[UnresolvedSexualTension UST]] was adequately resolved. It doesn't help that the novel series itself hasn't finished yet and the anime only adapted it up to the 4th volume.
* EnsembleDarkhorse:
** The Newspaper Club's Masashi Tougaito seems to be relatively popular.
** Misaki Sawaguchi, the girl better known by her OdangoHair who presented a theory to the Classics Club.
** Pay proper respect to our Empress [[ManipulativeBitch Fuyumi Irisu]]!
* FanPreferredCouple: Some popular fan pairings include Oreki x Irisu, Oreki x Mayaka, Eru x Irisu.
* MagnificentBastard:
** Without a doubt, Oreki.
** The Empress, Fuyumi Irisu definitely.
** Episode 17 ''definitely'' cements [[spoiler: Tanabe Jirou]] as one. [[spoiler: He plans and carries out the Jūmonji thefts in an [[PublicSecretMessage elaborate ploy]] to get his student council president, Muneyoshi back into manga drawing. To Tanabe's dismay, It fails.]]
* {{Moe}}: Eru definitely qualifies, and to a slightly smaller extent, Mayaka does as well.
* TheWoobie: [[spoiler:Chitanda's uncle, Jun.]]
** StoicWoobie: [[spoiler:Houtarou]]
** As of the SchoolFestival arc, Mayaka can count as well.
** Episode 17 cements Satoshi as one, as he gets to watch Oreki completely outshine him once again.
