After World War III, humans developed cerebral engineering, acquired new technology, and reformed their consciousness, changed the Western calendar to the galactic calendar, and built a new civilization. It has become possible to travel back in time by putting a time machine into practical use, separating only the consciousness from the body, and synchronizing it with a person from the past who has similar genes. Time travel was managed by the "Historical Research Bureau". However, scholars who advocate the fluidity of history go back in time to change history. The synchronized partner is Jesus of Nazareth from 5000 years ago . Investigator Verdal synchronizes with Simon Peter, one of Jesus' apostles, in order to monitor Jesus' actions and prevent him from changing history .
