Doomsday Sequence: Beginning in the Asylum

In 3027, a cosmic dust called the "Pale Rain" enveloped the world, causing 70% of the world's population to transform into "skeleton beasts" within 72 hours. The surviving humans discovered that by hunting skeleton beasts or coming into contact with specific ruins, the "sequence" genes in their bodies could be awakened. The sequence is divided into F to SSS levels, and the abilities cover element control, physical strengthening, mental power and rule system. After the collapse of social order, the three parties dominated by large shelters, private armies of plutocrats, and refugee settlements were divided, and resources (pure water, uncontaminated food, and sequence crystals) became hard currency.
