The Return of the Disaster-Class Hero

재앙급 영웅님이 귀환하셨다

Geon Lee was the strongest hero on Earth, the thirteenth saint in the war against the world-ending monsters known as calamities — until twelve fellow saints betrayed him and sealed him inside the Tower of Demons. Twenty years later he claws his way back out, stronger than before and intent on settling accounts with the allies who left him to die. Each of those saints now wields immense power of their own, and none will fall without a fight.
