A high school loner is given the part-time job of a lifetime as a modern day ninja tasked to perform international assassinations.

After World War II, Allied Command in Japan developed a new agency to help manage terrorism and violence within the Pacific region. The agency was staffed with ninja and they were initially tasked to handle domestic affairs. Eventually that program grew to its current form, managing 20,000 ninja across a range of domestic and international affairs. One of those ninjas happens to be Kudo. The seventeen-year-old high school loser is now poised to be the next line of defense against a potential surge in foreign assassins invading Tokyo.

Ten years ago, "the Gate" appeared and connected the real world with the realm of magic and monsters. To combat these vile beasts, ordinary people received superhuman powers and became known as "Hunters." Twenty-year-old Sung Jin-Woo is one such Hunter, but he is known as the "World's Weakest," owing to his pathetic power compared to even a measly E-Rank. Still, he hunts monsters tirelessly in low-rank Gates to pay for his mother's medical bills.

However, this miserable lifestyle changes when Jin-Woo—believing himself to be the only one left to die in a mission gone terribly wrong—awakens in a hospital three days later to find a mysterious screen floating in front of him. This "Quest Log" demands that Jin-Woo completes an unrealistic and intense training program, or face an appropriate penalty. Initially reluctant to comply because of the quest's rigor, Jin-Woo soon finds that it may just transform him into one of the world's most fearsome Hunters.

Gabimaru the Hollow, a ninja of Iwagakure Village known for being cold and emotionless, was set up by his fellow ninja and is now on death row. Tired of killing and betrayal, he wants to die. However, no method of execution works on him because as much as the seemingly apathetic Gabimaru refuses to admit it, he does have a reason to live. He wants to return to his wife, who was the reason why he softened up and failed to be an effective assassin. Thus, he refuses to die. Asaemon the Decapitator, a famous executioner, sees this and has a proposal for the ninja. He wants Gabimaru to join an expedition to an island south of Japan in search of the elixir of life in exchange for a full pardon by the Shogunate. However, this island isn't a normal island: it's believed to be Paradise. However the island is full of mysteries, and the exploring team—consisting of those marked for death—might not be fully prepared to handle them.

Lacking the very skill needed to survive at Easton, magic, Mash appears to already be at a disadvantage to his fellow classmates. In order to achieve his goals, Mash will have to fight his way through every trial using his fists alone, overcoming magic with muscles, all for the illustrious title of Divine Visionary!
