Klappentext

One hitman is feared above all in Japan: the killing machine known as "The Fable." But is he really a tough guy or more of a...weirdo? After a particularly lucrative spree necessitates a break from his life of crime, the Fable faces his hardest assignment ever: living as a normal guy, with a cover story, an apartment, and a pet parrot!
It's Way of the Househusband minus the wife and kid, plus one adorable, friendly bird, topped off with a whole lotta blood! Inspired the new anime.

Omnibus edition includes Vol. 11-12.
THE BOUGH BREAKS,
>An innocuous detective agency hides a criminal secret--they're entrapping doting helicopter parents and their entitled children, taking them for all they're worth, and burying the bodies with an excavator. It's a brutal racket, but it's not their first. Their last scheme was busted up, once upon a time, by none other than Fable. When he remembers a girl in a wheelchair from that hit years earlier, it'll shake loose memories and tempt him to act, just as the gang settles on their new victims: Etsuji and Misaki!
