* EnsembleDarkhorse: Technically, Misho is the central protagonist of Keychain. Don't tell that to Secret's fanbase, though.
* FanPreferredCouple: [[LesYay Marena/Secret]] is probably the preferred ship over Misho/Marena.
* LesYay: Occurs frequently between Marena and Secret, although it might be more accurate to state that Marena so sexy that anybody and everybody is likely to get shipped with her. This was ''heavily'' hinted to be canon. (See FantasticArousal.) One ''{{TabletopGame/Exalted}}'' forum had an unofficial poll to decide who Marena should be the [[ReincarnationRomance Lunar mate]] of. [[http://www.patternspider.net/forums/viewtopic.php?f=37&t=6772 Secret won.]]
* MemeticBadass: Ten Winds learned a permanent Charm that lets him deal aggravated damage to anyone less badass than he is. He hasn't inflicted bashing or lethal since.
* MemeticMutation: '''''DODGE CHARMS.'''''
* {{Moe}}: Secret, of course. Blossom is also just ''adorable''. For the [[MrFanservice female readers]], there's Misho.
* NightmareFuel: [[WhamEpisode Keychain of Creation, #189]]. [[AttackOfTheFiftyFootWhatever Marena's]] [[RedEyesTakeWarning flashback]] [[EldritchAbomination to]] [[DoomedHometown Thorns.]]
* TearJerker: Mew Cai's HeroicSacrifice right [[http://keychain.patternspider.net/archive/koc0063.html here]].
* TheScrappy: [[http://www.patternspider.net/forums/viewtopic.php?f=37&t=6575&hilit=hated Everyone hates the Placeholder.]]
* TheWoobie:
** Secret and Misho, mostly, though most everyone gets a turn.
** And poor Blossom. She just wants everyone to get along!
