Several years later, Sakamoto has settled into his humble life, but also grown portly as a result of his relative inactivity despite still being immensely powerful. The world of hitmen eventually locates him, and many soon attempt to target the Sakamoto family, either seeking revenge or resenting his retired status. Now, with the help of three other former criminals who become employed at the store under Sakamoto—clairvoyant hitman Shin Asakura, orphaned crime boss daughter Lu Xiaotang, and sniper Heisuke Mashimo—Sakamoto must protect his family (or die trying) against the criminal underworld, all while maintaining Aoi's no-kill policy.
