Sakamoto Days follows Taro Sakamoto, an unrivaled legendary hitman who was feared by every criminal and idolized by every assassin. One day, he fell in love, retired, got married, and became... a bit portly. Now, he runs a peaceful neighborhood convenience store with his family and has sworn a strict "no-kill" oath to his wife.

However, the underworld hasn't forgotten him. With a massive bounty on his head, Sakamoto must protect his quiet life from a never-ending stream of assassins. Alongside Shin, a young telepathic ex-hitman, and Lu, a daughter of a Chinese triad, Sakamoto fends off global threats using everyday store items—like pens, umbrellas, or even ramen—as deadly weapons. It’s a masterclass in creative action where the hero’s greatest challenge isn't killing his enemies, but defeating them without breaking his family's rules.
