Happy Kanako's Killer Life manga volume 3 features story and art by Toshiya Wakabayashi in full color.

Nishino Kanako used to be an ordinary office worker, but somehow she wound up with a dangerous new gig: working as a hitman! Turns out she’s got an enormous amount of talent for all things death and destruction, and the notorious contract killer known only as “K” is making big waves in the underworld. Maybe too many waves, as a matter of fact. With the police taking an interest in her work, Kanako is under new orders to lay low back in her hometown, but her cold-blooded coworker Sakurai somehow winds up tagging along.
