To all the people being disturbed that she just offed two random civilians whose only crime was being assholes, I think that's the point of this series. It's lighthearted, and Kanako is quite cute, but the point is that no matter how comedic or cute things are, Kanako is still a killer and can and will kill people, target or not. It's that kind of cognitive dissonance that makes this series something worth reading, imo.
