* AlternateCharacterInterpretation: Multiple characters, though the general interpretation question for all of them is: did these people ''really'' want to die when they signed the waiver? Or were most of them simply in a dark place, temporarily incapable of seeing any type of improvement coming and just wanted to take a break from everything?
** Kai. Is he really a NietzscheWannabe who thinks humanity, including himself, should all die? Or is he simply a young man who was broken by something in his past and could redeem himself?
* ManipulativeBastard: Kai. He's an adept of BreakThemByTalking and quite a good one at that.
* UncannyValley: The art-style in general. It's decent and the scenery looks wonderful, it's the people that end up looking a bit... unsettling at times. It likely has to do with the sketchy drawing style, alongside the heavy emphasis and ''big'' noses that the characters can look a bit uncomforting to some readers.
