YMMV for the original manga
- Epileptic Trees and Wild Mass Guessing: Hoo boy...
- Evil Is Sexy: Ivy, Maeve, Sana-Kan
- Foe Yay: Between Dhomochevsky and Pcell. Maybe...
- Germans Love Blame!: More so than any other country, it seems. There is even an electronica band inspired by the series.
- Padding: Given that it's a Walk the Earth story with a rather simplistic plot, this is to be expected.
- The Woobie: Killy is an Iron Woobie and a Stoic Woobie wrapped into one unstoppable being.
YMMV for the 2017 Netflix film
- Awesome Music: Killy's Main Theme is a beautiful and somber piece.
- Broken Base: The film has split the fandom in a few areas: is it better than the 2D anime or is 3D the only way to really adapt the setting? Are the changes done to the plot welcome and allow newcomers to get a better grasp of the plot or are they needless and badly thought-out? Was focusing on Zuru a good idea? You will find supporters on either side, though many are glad the film exists.
- Hilarious in Hindsight: This film becomes very comical in comparison, if you remember that MC very similar to Killy already make up a love triangle with Sana-kan and Cibo in the released after a couple of months the film on The Irregular at Magic High School. Especially considering the contrast between the actions of Saori Hayami in both films.
- Uncanny Valley: The strange coldness on the faces of the protagonists and the slow motion animation in general, can make half cast quite frightening and depressing.
- Visual Effects of Awesome: The fight scenes and backgrounds look gorgeous, to say the least.
- The Woobie: Fusata becomes this in the climax when he realizes Tae, his best friend and love interest, was killed and replaced by Sana-kan, pushing him into a Heroic BSoD for several minutes while the city is invaded by Exterminators. Although he eventually regains his composure and contributes to the city's defense, he is still visibly grieving.
