* {{Iyashikei}}: Though the series does possess a romantic subtext to a degree, it is heavily downplayed by the SliceOfLife and {{Comed|y}}ic nature of it, focusing more on the playful hijinks amongst its [[EnsembleCast large variety]] [[CastOfSnowflakes of characters]].

* SenpaiKohai: Most of the teams are mixed of upper and lowerclassmen, which in turn makes way for such a relationship amongst teammates. For example, Team Ox upperclassmen Shion and Suzuran act like [[CoolBigSis older sister figures]] to their underclassman, Ajisai.

* DoesNotLikeShoes: Both PlayedStraight and {{inverted|Trope}}. In the character art, nine of the thirty-eight characters are wearing sandals while the rest wear stirrups, bandages, or go barefoot. However, in the anime proper, twenty-six of the thirty-eight are wearing sandals, while the remaining twelve[[note]]Sazanka, Shion, Itadori, Higiri, Hasu, Uikyou, Hinagiku, Kibushi, Oniyuri, Benisumomo, Touwata and Shakuyaku[[/note]] continue to play this straight.

* {{Demonization}}: {{Justified|Trope}}. The Akane and Aoi Classes teach their students that the opposite gender is dangerous and forbid interaction between them. [[spoiler:This is actually a lie enforced by the two classes when they used to live together, after [[{{Elopement}} an alarming number of students began coupling off and leaving the village]], risking the waning and possible disappearance of the lifestyle and customs of the shinobi discipline, resulting in their present-day isolationism]]. [[In the manga's finale chapter, both classes agree to abolish this rule and begin to gradually allow their students to intermingle with each other]].
