Dr. Jurgen of DC has developed a global defense system to counter potential alien threats. The system comprises two main components: the VTX‑001 Vartoul unmanned anti‑alien PT and the ODE worldwide network that governs these drones. However, the system contains a crucial secret: a living human is required to control the ODE core, and the core relies on human organs to sustain itself. At present, the drones have begun a mass abduction spree, and Kyosuke and his team have been dispatched to address the situation.
