* AlasPoorVillain: [[spoiler:Try not to tell us you don't feel for the guy when you realize his PsychicPowers brought him nothing but pain and misery]].
* PsychoElectro: Shin is a ''major'' aversion. [[spoiler:While he ''does'' have ShockAndAwe and ''is'' the BigBad, he's a very [[TheStoic calm and collected person]], and never seems particularly insane except for his irritation with vocal communication (which he mainly uses to deflect questions about his actions). He only freaks out during his MotiveRant, and Sai makes him pull a HeelFaceTurn in the middle of it following her declaration of love]].
* WoobieDestroyerOfWorlds: [[spoiler:Shin agreed to let himself be the first test subject in the early stages of a project that would boost human empathy to the point where verbal language would be unnecessary. However, he only picked up on the selfish and negative emotions of those around him, leading him to believe that HumansAreTheRealMonsters, thus relegating to activating Class Cage again for a second time, which would really be TheEndOfTheWorldAsWeKnowIt. All this is stopped when he realized [[ThePowerOfLove Sai was in love with him all along]]]].
* LovingAShadow: The Merchant collects and scrounges around for anything shiny [[spoiler:so his "princess" can smile again. Unfortunately, the "princess" died in her cradle; the Merchant doesn't even realize this when Seto wants to tell the truth. If it wasn't for Sai, the Merchant might've either [[DespairEventHorizon completely broken down into despair]], or possibly killed the boy on the spot]].
