* FunnyAneurysmMoment: Not in the show per se, but in its North American release. The last episode released by Geneon before its collapse, episode 10, is titled "Good Things Come to Those Who Wait". Episodes 11+ would not see the light of day in North America for another full year; many of the show's fans in 2007 doubted it would ever happen.
** Kouyuu's constantly getting lost is a RunningGag of the series. In a side story, when he was brought back to the Kou residence by Reishin, he was "persuaded" to stay by being told that the house is haunted and the monster would get angry if he tried to run away. Furniture in the house were then constantly rearranged to reinforce the story and to make sure that the boy could not run away to the point that it completely screwed up his sense of direction. While it is done with good intention, it is still a horrible thing to do to a child.
* HoYay: Oh so much. Occasionally played for laughs in the early episodes, such as when Shuurei speculates that Ryuuki and Seiran might be in love with each other. [[spoiler: Even funnier in later episodes when it is revealed that Ryuuki and Seiran are brothers.]]
* RealWomenNeverWearDresses: Beautifully averted. Shuurei is able to be successful in a male-dominated society through brains and hard work, and she's allowed to be as feminine as she wants while she's doing it, dammit.
* ValuesDissonance: Advisor Sho's [[spoiler: inaction during the Struggle for the Throne, so that a worthy emperor may reveal themselves, makes much more sense when you understand how the Mandate of Heaven works.]]
* TheWoobie: Ryuuki and Eigetsu.
