* CompleteMonster: The "Father" of Nana.
* CrossesTheLineTwice: Played straight at first, then horribly subverted as it quickly crosses the line again, and then [[SerialEscalation veers at a non-euclidean angle to cross over an infinitude of lines that should not even exist.]] There is a term for people that are [[CompleteMonster still laughing at the comic by the last few strips.]]
* CrowningMomentOfHeartwarming: Despite everything she's gone through, [[spoiler: when Nana dies, she resurrects the dead kitten she spent her last few hours of life with and makes flowers bloom in the alley she died in.]] Doubles as a major TearJerker.
* DarknessInducedAudienceApathy: A common criticism by detractors.
* MemeticBadass: Even people [[MemeticMutation who have no soul]] cry at this!
* NightmareFuel: Combined with {{Tearjerker}}. Nana's world is the sort of existential nightmare where life has no meaning, there will never be a happy ending, and no matter how you hope, no matter what sort of happy ending you may beg for, there will only be pain. And cuteness, which only makes it worse.
* TearJerker: You have no idea.
* TheWoobie: The armless, legless woobie who lives in a box.
