Sakamoto Days follows Taro Sakamoto, a legendary hitman who retired to run a neighborhood convenience store with his wife and daughter. After falling in love and starting a family, he gained weight and now lives a peaceful, quiet life. However, his past refuses to leave him alone; former enemies, bounty hunters, and various assassins constantly target him and his family. To protect his simple life, Sakamoto uses his incredible, almost superhuman combat skills—often in creative, improvised ways—to dispatch threats without killing them. Readers enjoy the series for its perfect blend of high-octane, stylish action and hilarious comedy. The contrast between a chubby, goofy dad and an unstoppable killing machine is endlessly entertaining, and the colorful cast of quirky allies and villains keeps the story fresh and exciting.
