[Infinite Flow + Plot-Driven + Mild Supernatural Elements + Multiple Job Classes and Leveling]
An upside-down tower beyond the bounds of reality has appeared. Anyone who clears its trial dungeons can gain supernatural powers.
But the price of obtaining those powers is to pawn your life and continually face the upside-down tower's brutal trials.
To survive, you must constantly evolve your job class, level up, and grow stronger.
Greed and fear, humanity and savagery, fearlessness and selfishness will play out here time and again.
While every supernatural being struggles between desire and retreat,
while every supernatural being trembles before the authority of those who rule the rules,
my heart remains calm.
Because I am the heir to the ruler!
And I am also the final gatekeeper.
