- Crazy Awesome: Hinako. How else would you describe a person who somehow manages to get a car on top of a skyscraper undetected, then roof hops down with said car to catch up with her partner—simply because the streets were too narrow to drive normally?
- Darkness-Induced Audience Apathy: Once you get past the loads of Fanservice and cool action moves, you remember that Koumori is a psychopathic murderer on death row, with a higher body count than every single other murderer introduced so far combined. She has no wish to atone, does not believe in serving some noble goal, and gleefully causes needless collateral damage and kills bystanders without a thought. The only reason she works with the police is because she gets to kill more people and is provided a stay of execution. And she constantly tries to cheat on her girlfriend. It makes it difficult to really root for her, almost crossing into Rooting for the Empire territory when the reader hopes one of her fights will end with her losing. The cops are shown to be at least decent people, and reluctant to work with her, but see it as a necessity and are largely powerless to do anything.
- Spiritual Adaptation: Murcielago is essentially the closest thing we'll ever get to a Killer Is Dead manga. It's hard to tell exactly which one came first, but given how both follow womanizing Professional Killers with dubious mental health working for the government with a wacky, high-school aged partner, the comparisons aren't unwarranted.
YMMV / Murciélago
