Taro Sakamoto was once renowed across the criminal underworld as the undisputed king of contract killers. Feared by syndicates and respected by rivals, he abandoned the assassin trade overnight after falling in love with Aoi. Trading his customized weaponry for a convenience store apron, Sakamoto settled into domestic life, gained weight, and became a quiet family man and neighborhood shopkeeper. To ensure his wife and daughter remain safe, Sakamoto agreed to an absolute family pact: never take another human life under any circumstance.

Peace proves short-lived when a massive bounty lands on Sakamoto's head. Shin Asakura, a telepathic hitman and former subordinate, arrives with orders to execute his old mentor. Recognizing Sakamoto's enduring combat brilliance and steadfast moral dedication, Shin switches allegiances to become a loyal store clerk. Soon, additional allies join the household, including former triad martial artist Lu Xiaotang and sniper Heisuke Mashimo, transforming the mom-and-pop grocery into an unlikely fortress against hitmen, rogue bounty hunters, and death row escapees.

The conflict escalates as the Japan Assassin Association (JAA) and its elite enforcement unit, the ORDER, collide with a revolutionary criminal faction led by Kei Uzuki, known as Slur. Caught between government-sanctioned killers, former comrades like the eccentric Nagumo, and an insurgent force determined to dismantle the underworld order, Sakamoto must employ everyday tools, grocery stock, and sheer physical conditioning to neutralize lethal threats without breaking his non-lethal family oath.

What to Expect

Sakamoto Days stands out through precise, dynamic action staging and inventive choreography. Rather than relying on mystical spells, combat revolves around hyper-kinetic gun-fu, environmental physics, and unconventional weaponry. Ballpoint pens, price labelers, ramen bowls, and cash registers become lethal deterrents in Sakamoto's hands. Narrative pacing transitions fluidly from warm, deadpan comedy to high-stakes tactical warfare, moving across major story arcs including the Lab Arc, Death Row Prisoners Arc, JCC Infiltration Arc, and the sprawling Century Museum battle. The central tension remains constant: neutralizing world-class assassins while strictly honoring an unyielding non-lethal restriction.
