Shiawase Kanako no Koroshiya Seikatsu

Anime

When Kanako accidentally applies to work at an assassination agency, the timid office worker discovers that she has a knack for bumping people off. Will she ever earn the respect of Sakurai, her prickly and kinda hot co-worker-and why is she still having silly workplace problems when she's employed with hitmen?! This full-color manga is dangerously funny! (Source: Seven Seas Entertainment)
