Nagi is an assassin on Gui Cheng Island, considered the most dangerous city in the universe. Since saving his younger sister Shizuka Taira's life by taking a bullet, he's used a wheelchair. He was so badly injured that he's been in a coma ever since. Only when he senses the urge to kill does he awaken and transform back into a dangerous assassin—now one in a heavily armed wheelchair. His sister sets out to find an opponent so dangerous that her brother will permanently awaken from his coma. This allows her to continue accepting assassination contracts, which Nagi then carries out. The riskier the missions, the better for her brother. Shizuka hopes that after a particularly grueling battle, he will be permanently cured.
