* AngstWhatAngst: Koji seems pretty cheerful despite what happened to him in the cemetery story.
* CreepyCute: The Morback species, the most notable member being Sers. They're a race of anthropomorphic bat-like aliens that have terrifying [[SlasherSmile Slasher Smiles]], [[BloodKnight are known for their hunting skills]], their mating rituals [[DeathbySex could kill a person]], and [[ArsonMurderandJaywalking normally take a career in the medical field]]. However they also [[FullFrontalAssault hate wearing clothes]], can look cute when they aren't giving a SlasherSmile, and [[AffablyEvil can be very friendly if you aren't their prey]].
* EnsembleDarkhorse: A lot of them but Koji, Juu, Ruri, Ashido and Chovek stand out.
* MemeticMutation: OBNOXIOUS GREEN CAR.
* {{Misaimed Fandom}} - Certain readers regarding Soshika's racism against humans as an admirable trait. Largely resolved by direct intervention from the creator. [[http://inhuman-comic.com/payattention.php]].
** A great majority of the fans like the comic more for the Nikitak species than the comic itself.
* TheWoobie - Kyo, and to a certain extent Ashido and Jet.
** JerkassWoobie: Soshika, when you think about how racist she is to humans.
