Every awakened individual gets one chance to enter the Tower of Trials.

Most people aim to survive.

Cheon Sia chooses Hell difficulty.

Blessed with the S+ trait Immortal and the ability to grow stronger through every near-impossible ordeal, Sia quickly discovers the fastest path to power is also the most painful. Deadly traps, impossible bosses, and certain death become little more than training exercises as she throws herself into challenge after challenge with alarming enthusiasm.

Rumors soon spread throughout the Tower.

Somewhere in Hell difficulty lives a lunatic who refuses to leave, keeps coming back from death, and treats impossible trials like a hobby.

They're only half right.

The legend isn't some crazy guy.

It's her.
