Taro Sakamoto once stood unchallenged at the summit of the criminal underworld as the most feared hitman in modern history. Everything altered the afternoon he fell in love with Aoi. Abandoning assassination contracts overnight, Sakamoto married, started a family, opened an unassuming neighborhood convenience store, and put on substantial weight as a content family patriarch. His domestic peace is conditioned upon an unbending vow made to his wife: never kill anyone again, under penalty of immediate divorce.

Civilian quietude collapses when the Japanese Assassin Association (JAA) and rival syndicates designate Sakamoto for elimination. His former subordinate Shin Asakura—a clairvoyant hitman armed with mind-reading abilities—arrives to execute him, only to switch sides and join the grocery staff after witnessing Sakamoto's lethal prowess, which remains razor-sharp despite his altered physique. Joined by exiled triad combatant Lu Shaotang, the trio defends their community store from waves of bounty hunters, rogue death row convicts, and the mysterious anti-JAA faction headed by the enigmatic Slur (Uzuki).

As high-ranking enforcers from the Order enter the field to purge insurgents, Sakamoto must protect his wife and daughter while balancing inventory restocking, store sales, and high-velocity shootouts. Facing assassins wielding cutting-edge weaponry, Sakamoto counters through pure mechanical instinct, improvising lethal defenses out of price tag guns, ballpoint pens, and shopping carts while strictly preserving the lives of his attackers.

What to Expect

Sakamoto Days transitions rapidly from episodic neighborhood comedy into breathless, high-stakes battle shounen arcs. The narrative structure revolves around hyper-kinetic combat choreography heavily inspired by classic martial arts cinema. Combatants rarely trade static power blasts; instead, duels utilize kinetic momentum, environmental geometry, and everyday store tools turned into defensive instruments. Key milestones such as the Amusement Park skirmishes, the Death Row Prisoners Arc, the JCC Transfer Exam Arc, and the Museum exhibition battle consistently raise the mechanical scale. Readers monitoring the anime-to-manga bridge who finished Season 1 of the TMS Entertainment anime should begin reading directly at Chapter 75, which picks up right at the JCC infiltration sequence.
