You're Dead, Kid!

Zero is an assassin trying to get out of his line of work, but every time he gets close to escaping, something pulls him back in. He finds solace in his best friend, Summer, sharing a common trait; they both don't know their parents. Things seem to be getting normal until Summer's dad calls, demanding Zero bring Summer back to him, or else Zero would be taking a dirt nap. Enlisting help from his two friends, together, the four must cross five cities, all the while avoiding gangs and hardships, all in the name of returning the daughter of a mob boss.
