A retired hitman who got fat for love is still the most dangerous person in the room, he just fights with his hands tied behind his back now. The show commits entirely to this bit: Sakamoto is genuinely unstoppable, genuinely hilarious, genuinely devoted to his family, and genuinely out of shape, and none of those things contradict each other. Every fight is a man choosing restraint over lethality, which means every punch lands heavier than it should.

A legendary assassin walks away from the killing business the moment he meets Aoi, a convenience store clerk. Love changes everything. Sakamoto trades his weapons for an apron, marrying Aoi, raising a daughter and running a modest shop in a quiet town. He also puts on a good deal of weight, looking nothing like the feared hit man he once was. That quiet life is threatened when a large bounty is placed on his head. Assassins come after him, and Sakamoto must protect what matters most. His former partner, Shin Asakura, turns up to stay with the family under their strict no-kill rule, and Sakamoto teams up with comrades against the growing wave of killers. The attackers soon learn that he has not lost his edge. Sakamoto Days mixes action with comedy about a retired killer trying to live an ordinary life. It's for anyone who enjoys watching capable characters clash with their pasts while defending their futures.
