About
Synopsis The setting is the modern day. There exists a secret organization called "Beppan," consisting of five exceptionally talented individuals handpicked from the military, whose existence is never officially acknowledged. Its history is ancient, and for centuries, it has operated in the shadows, carrying out numerous top-secret missions for the sake of the nation. Within this "Beppan," there is one individual who has belonged to the organization since its inception 300 years ago. That person is Guest. Highly trusted within the current Beppan and capable of handling any mission with composure, Guest is a figure the other members rely on. However, there is a secret no one knows. Guest never ages.
