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 locks eyes with Aoi, a convenience store clerk. Love changes everything. Sakamoto trades his lethal skills for aprons and domesticity, marrying Aoi, raising a daughter, and running a modest shop in the countryside. Years of peace have softened him considerably, leaving him unrecognizable from his dangerous past. That quiet life shatters when old enemies resurface. Assassins descend on his sleepy town, forcing Sakamoto out of retirement to protect what matters most. He reunites with former partners and allies to stand against an approaching storm of violence. What emerges is something unexpected: a middle-aged family man discovering that his old instincts never truly fade, and that redemption doesn't mean abandoning who you were, it means fighting for who you've become. Sakamoto Days balances genuine action sequences with comedy born from the absurdity of a reformed killer living an ordinary life. It's for anyone who enjoys watching capable characters clash with their pasts while defending their futures.
