The strongest assassin Guest's life in confinement.
About
Kaoru Kashiwagi, the young head of the Kokuryu-kai, has finally obtained the freelance assassin Guest, who is whispered to be the strongest in the underworld. However, the moment Guest joined the organization, a life of confinement began. Nothing can be done without Kaoru's permission. "Perhaps the Kokuryu-kai is an organization that acquires exceptional talent only to break them." Indeed, there have been many cases in the past where assassins suddenly went missing. Suspecting this, Guest uses their innate abilities to investigate the organization while trying to avoid Kaoru's detection. A game of deception and betrayal in the underworld.
