There are people with super powers in this world, and the ratio is five thousand to one. They are hidden among ordinary people and controlled by a secret agreement signed in 1987 - the "Iceberg Treaty". The treaty stipulates that any person with supernatural powers shall not reveal his abilities in front of ordinary people. Violators will be "cleared" or "accommodated" by the official supernatural organizations of various countries.
The official organization "Candle Dragon" is responsible for maintaining the implementation of the Iceberg Treaty. Outside the country, there are organizations such as the "Temple", "Blood Pact", and "Nibelungen" who are eyeing it. And above all these forces, there is an even older shadow - those Sequence 1s who have existed since before World War II, who have long since disappeared into the depths of history, waiting for a certain moment.
