In 2030, the Large Hadron Collision experiment accidentally opened a micro-dimensional rift. The parallel world "Netherworld Dimension" overlapped with the real world, causing the leakage of spiritual energy (energy from another dimension). The rift followed the "spiritual vein resonance cycle", with an energy peak occurring every 49 days. The government established the "Inter-Dimensional Affairs Administration", and supernatural events were officially included in the emergency management system... The future has arrived.
