A PSP port of Omertà: Chinmoku no Okite.

J.J is a most dangerous hitman in a city befitting of his profession, excelling at his job to such a degree that his nickname is ‘Death scythe’. Given a job with a lot riding on it by one of the city’s factions who are at war, when it’s time for him to go in for the kill his target isn’t in the room he was assigned to. Instead, a couple lie dead on the floor who’ve nothing at all to do with the job. As if things weren't getting suspicious enough, the son of the couple bursts into the room and assuming that J.J is the murderer of his parents, wants revenge and vows to kill him no matter how long it takes.

Five years later they’re living together and keeping a low profile, to avoid rousing suspicion over what happened then. J.J still takes assassination jobs, shady deals are still being made, and the factions Dragon Head and King Caesar are still at war. Eventually J.J manages to draw the attention of the two groups. In the end, whose side will he take?
