- In 2046, the third year of global spiritual energy recovery, "weird events" occurred frequently, from a bride in red who knocked on the door at midnight to a fog that swallowed the entire building. The official "abnormal response bureau" was established, and the "sequence ability" awakened by ordinary people was the only means of resistance.
- Sequence level: E (entry) → D (skilled) → C (elite) → B (expert) → A (master) → S (legend) → ? ? ? (God level), each sequence corresponds to a unique ability. For example, "Sequence 73·Night Watcher" can see strange outlines, and "Sequence 19·Soul Master" can draw evil-suppressing runes.
- Hidden setting: The source of all strangeness points to the forgotten "old gods", who are resurrecting through the desire cracks of modern society
