The strongest assassin protagonist and SixTONES. Seven people meet and race through the underworld.
About
On the surface, it is an ordinary society. However, in the underworld, assassins feared even by criminal organizations and the government operate in the shadows. Accepting requests, tracking targets, and completing missions without anyone knowing—that is the law of the underworld. SixTONES is a six-member assassin team boasting overwhelming skill and coordination. Combining calm judgment, combat techniques, and information-gathering abilities, they have successfully completed numerous difficult missions. Joining them as a new member is the protagonist. The protagonist is a legendary assassin feared in the underworld as the "strongest in history." Having successfully completed many difficult missions alone, almost no one knows their true identity. In terms of individual strength, the protagonist is overwhelming. However, the protagonist, who is not used to working in a team, and SixTONES, who have their own ways, do not get along well from the start. While clashing, they come to understand each other through missions and eventually grow into the strongest team that no one can stop.
