SAKAMOTO DAYS starts with a perfect contradiction: Taro Sakamoto used to be the greatest hitman around, then he fell in love, retired, gained weight, opened a shop, and chose peace. The assassin world does not politely accept that decision. Old enemies, young killers, criminal organizations, and dangerous colleagues keep pulling him back toward violence, while Sakamoto keeps trying to protect the ordinary life he actually wants.
Yuto Suzuki's manga makes that setup work by treating action and comedy as partners. Sakamoto can be deadpan, domestic, and ridiculous in one scene, then terrifyingly precise in the next. The result is not just a retired-assassin gag. It is a franchise about whether someone built for violence can keep choosing family without losing the skills that made him feared.
The official anime site has continued the story with new broadcast information, while Netflix's title page frames the premise around Sakamoto's past catching up with him. TMS Entertainment handles the anime adaptation, and Netflix gives the franchise a broad streaming entry point for viewers who did not follow the manga first.
SAKAMOTO DAYS is easy to recommend to action fans who want choreography with personality. It has assassins, secret orders, brutal fights, and increasingly strange opponents, but the emotional center stays charmingly domestic: a man who already escaped the life everyone else still thinks defines him.
