First S-Rank Gate

The First S-Rank Gate is the earliest recorded gate of that caliber, marking the beginning of the S-rank classification system and humanity's realization of the existential threat posed by high-level dungeons.

Its dungeon break unfolded as one of the most devastating disasters humanity had ever faced. The scale of destruction was staggering — landscapes were scarred, entire cities were left in ruins, and the loss of life was catastrophic.

This gate first exposed the true vulnerability of humanity against high-rank dungeon monsters. It accelerated the development of hunter ranking systems and forced governments and guilds to recognize the dire need for S-Rank Hunters capable of confronting such apocalyptic scenarios.

To this day, the legacy of the First S-Rank Gate looms over every subsequent high-rank gate break. It remains a grim benchmark and a historical warning that shaped international protocols and the very foundation of modern hunter response forces.
