The Fable Omnibus 2 (Vol. 3-4) (manga)

The deadliest man in Japan has a new mission: Take a yearlong break, and don't kill anybody. After getting a pet parrot, “Akira Sato” (not his real name) is at a loss. What do normal people do? They get a job, right? So the Fable musters his courage, writes a resume, and promptly discovers that job interviews are much trickier than they seem. Practically by divine luck, a neighbor gets him a job at a design company. But how long will the underworld let a legendary assassin slave away at a 9-to-5?
