* GrowingTheBeard: The first chapter barely touches social themes and comes across as a comedy. However, the beard appears next chapter.
* HoYay: See HoYay/{{CLAMP}} for details.
* ItWasHisSled: [[spoiler: Seishirou is: the Sakurazukamori, the man Subaru met nine years ago, a [[TheSociopath murderous sociopath]], and Hokuto's killer.]] The first two [[TheUntwist aren't much of a twist]], but the last two make for one hell of a WhamEpisode.
* MagnificentBastard: [[spoiler: Seishirou]] turns out to be a massive asshole. But he's one very, ''very'' stylish and efficient SOB. [[spoiler: And if anything, he becomes ''even more of a MagnificentBastard'' in {{X 1999}}.]]
* MemeticMolester: Seishirou, thanks to a certain annex and his tendency to be... well, Seishirou.
* {{Narm}}: You either laugh or facepalm with the OVA theme song "Kiss Kiss." It repeats the same {{Engrish}} words over and over.
* WhatDoYouMeanItsForKids: The manga was aimed at teenagers in Japan but its themes are surprisingly dark. Before the end, the authors received lots of letters asking for a happy ending but this did not change the writers' plan.
