- Accidental Innuendo: Many, very many jokes in the series are this because of the frequent use of Memetic Molester and the Accidental Pervert.
- Sakura puts in Kyo's mouth a bun with a sausage with the words "stop thinking about something perverted!" after she caught him on fantasies about her with open mouth.
- The girl's debate about who will get to sleep with Kyo in the fifth episode. Master even Lampshades it, saying "if Sakura and Kyo will sleep together, it could end up by a child", after which the dispute continues in an even more ambiguous form.
- In the same episode, after meeting his brother after the journey, Kurumi says: "You do not play with me, but you agree to spend the night with them!". Oh.
- Audience-Alienating Premise: The surplus of Lolicon jokes and fan-service with little girls quite quickly scared off a good amount of Western viewers.
- Broken Base: Fanservice, dear boy. While many viewers and critics called this the most shameful and annoying moments in the show, and ANN reviewers even lowered the rating several times, others don't mind and instead view it as a "cute" part of the story and characters rather than the reason for the series to exist (and then there are those who do just that). The fact that Dengeki considers Jun to be a real lead-female character and even places her along with other heroines in erotic mini-games and official art does not help much.
- Genre Relaunch: The adaptation of this novel was intended as an attempt to resurrect young girls's trend in anime. Though considering other highly successful series with young girl main characters and Fanservice, such as Fate/kaleid liner PRISMA☆ILLYA, Magical Girl Lyrical Nanoha Vi Vid, Eromanga Sensei or No Game No Life just to mention a handful, one wonders if that's really needed.
- Hilarious in Hindsight: The fact that the younger sister of the protagonist is informally in his "harem" has caused quite a few jokes about how Dengeki Bunko seems to have been overly addicted to Little Sister Heroines lately.
- Memetic Molester: Whether you like it or not, the show intentionally constantly puts Kyo in a situation where he looks like a Lolicon to play it for laughs and embarrassing situations.
- Moe: Naturally, given the genre. Also a given due to the writer and two-women artist team Tinkle doing the illustrations again, as they formerly joined up to make Ro-Kyu-Bu!, which was absurdly moe.
- So Bad, It's Good: A part of the audience sees the work as this, given straightforward Lolicon themes and fanservice, and some artificiality of the plot settings.
