* FanPreferredCouple: [[OppositesAttract Ibara/Ran]] and [[BodyguardCrush Rei/Sei]]. [[spoiler:They both end up becoming the {{Official Couple}}s.]]
* HoYay:
** Isagi Houjou asks Ran to dance with him, as he would rather dance with "beautiful" Ran than "strange girls," comments that Ran should wear a dress, calls her "Ran-chan," and steals a kiss from her. Subverted as Ran is a girl and Houjou ''knows'' this because he's old friends with Rei, but everyone who doesn't know that assumes that Houjou is interested in a guy until Sei lies that Houjou's antics were a "performance" to liven up the dance.
** After learning about Ran's true gender, [[spoiler:Souda]] admits that he did notice that her facial expressions were pretty at times and that it made sense that she was a girl. He even adds that there were times he thought he was [[SweetOnPollyOliver turning "gay"]] because of her.
* IKnewIt:
** There were several fans who already figured out that [[spoiler:Ran's older brother Rei would be alive.]]
** And that the reason behind his FaceHeelTurn was really to [[spoiler:protect Sei.]]
* LesYay:
** Naturally between [[TheChampion Ran]] and [[{{Protectorate}} Sei]]. And then there's their mutual {{unwanted harem}} [[EvenTheGirlsWantHer of girls]].
** At one point, Ibara even teases Sei, saying that she must sure love her "sir knight," and Sei agrees with a straight face, which later causes Ibara to wonder if Sei meant something different with Ran and wonders if he's thinking about it too much.
* StoicWoobie: Both Ran and Sei can be considered this.
