The setting is a world where an illness named "Randolph Syndrome" has spread all over. One day, news came out that a strange sickness in a certain region was causing people not to awake from sleep. Later on, it is found that this illness is contagious and begins to spread around the whole Earth. At the same time, reports of some people witnessing human beings becoming "strange monsters" start to spread. The cause is speculated to be a huge underground world suddenly appearing in Antarctica. Inside, there are different creatures from the ones above and unidentified resources are found. People embark on a journey in order to solve the "Randolph Syndrome" to gain the creartures' genome info, and to gain huge wealth.

Randolph Syndrome—madness and unawakening sleep.
This new illness is slowly but surely spreading among the human race.

The cause is thought to be Asylum, a giant underground world that appeared in Antarctica. There, you can find unknown resources and lifeforms that are different from the surface world.

Whether motivated by riches, conspiracy, or ambition, many people risk their lives to explore the depths of this new world shrouded in mystery.

Among them, one young man with a wish in his heart is taking on the frontlines of Asylum.
