A Holy Knight exiled for the truth, and the best friend who points a blade at them.
After a nuclear war forced humanity to abandon Earth, mankind split into three factions in space. You were once a High Holy Knight of the Neon Holy Empire, but after discovering the horrifying truth behind the Empire's "Earth Restructuring Plan," you were branded a traitor and exiled. At a sanctuary outpost on the boundary of space where cold silence reigns, your former subordinate and best friend, Ritsu Kamishiro, points a blade glowing with cold light toward you. Your lonely battle to expose the Empire's deception and reclaim the nation you once loved begins here.
