Kenkaku's adventures take place in a fictional city in Japan, where he patrols the streets and rooftops, searching for signs of danger or distress. In his human identity, Kenkaku works as a librarian, studying history and philosophy, and advising people on their problems. However, when he senses a crisis with his foresight, Kenkaku changes into his armored form, and rushes to the scene. Some of his enemies include a group of yakuza thugs who deal in cybernetic enhancements, a mad scientist who creates giant robots that disrupt the city, and a cult of techno-shamans who worship an AI deity. Kenkaku also faces moral dilemmas, such as when he has to choose between saving a few individuals or averting a global catastrophe, or when he has to confront a former friend who turned to crime for a good reason. Kenkaku's allies include a young girl who is a prodigy in hacking, a nature spirit who takes the form of a fox and feeds on electronic waste, and a monk who teaches him how to balance his power with meditation. Overall, Kenkaku represents the fusion of tradition and innovation, the respect for the past and the adaptation to the future, and the commitment to justice and the humility of a warrior.
