* {{Anvilicious}}: No chance is spared to emphasize the importance of having fun.

* ArcFatigue: Many readers consider the "Peter Pan" story line to go on for way too long, especially considering [[BigLippedAlligatorMoment how it doesn't match the rest of the setting.]]
* BigLippedAlligatorMoment: The "Peter Pan" arc is very bizarre, with a ghost invading the dreams of some of the main characters and trying to trap them in a world of eternal youth. Considering this manga is a SliceOfLife with little to no supernatural elements, it's especially jarring.
* DieForOurShip: Kokoro. The fact that he is Hikari's new love interest to sway off yuri fans didn't sit too well for them.
* LesYay:
** [[PseudoRomanticFriendship Futaba and Hikari]] have a lot of this, such as Hikari's habit of standing ''very'' close to Futaba, holding hands with her and gazing into her eyes, especially in the first volume. Though Futaba seems to inspire this quite a bit from others as well.
** Mato-sensei giving Futaba a foot message comes off this way because of Teko's expression.
** In the last scene of the anime, the things Hikari tells Futaba could easily be interpreted as a {{love confession}}.
** Episode 6 of season 2 has Teko enter a race just to win a kiss from the "prince" Hikari (though she ''says'' it's in order to protect her), as well as the two having an intimate prince/princess fantasy while they're in the bath together.
* MemeticMutation: "Hikari is [[Franchise/TheMuppets Kermit the Frog]]!" (due to her exaggerated facial expressions making her resemble a muppet, combined with her green hair)
%%* {{Moe}}: Futaba. [[http://www.mangahere.cc/manga/amanchu/v02/c014/ COME]] [[http://www.mangahere.cc/manga/amanchu/v02/c014/23.html ON!]]
* PlatonicWritingRomanticReading: The massive amount of subtext Amano put between Hikari and Futaba had many readers believe that this might lead to a romantic payoff. Alas, [[spoiler:Amano thoroughly [[ShipSinking sunk that ship]] by turning Kokoro into Hikari's ''male'' love interest.]]
* TheScrappy: Kokoro is not a well loved character, owing to his [[{{Jerkass}} constant rudeness to Teko]] and interference with the FanPreferredCouple of Teko and Pikari.
* UglyCute: Cha and Ohime look rather weird for animals that are supposed to be cats, and that is putting it mildly. Some may argue though that this also makes them stupidly adorable.
