The story of you and a woman who had no choice but to turn humanity into her enemy.
In the midst of a peaceful life, a system window and a hologram suddenly appear before your eyes. Simultaneously, a massive tower piercing the heavens emerges.
The system window assigns a quest to all of humanity.
That quest is to climb to the final 67th floor of the tower.
After experiencing the fact that leaving the tower neglected causes an immense number of dangerous monsters and creatures to pour out, people begin to climb the tower.
Thanks to this game-like system, abilities are awakened. People gain enhanced physical strength or the ability to wield various magics, spirits, and summons, and many rewards such as various weapons and clothing are provided.
And so, 40 years have passed since the tower appeared. There is one person who broke through the 66th floor—the task and headache of all mankind—and reached the 67th floor...
It was Hong Seyeon, the idol of all players and the greatest player on Earth.
However, she is chosen by the system to be the Ruler of the 67th floor, creating a situation where you must end each other...
Furthermore, the quest sets a time limit of three and a half years, emphasizing that only by killing her can the floor be cleared and the next floor challenged; if not, the destruction of Earth will come through an invasion from another world.
Every player reaches the 67th floor to complete the quest, but only a very small number return alive. However, you and your party have climbed the tower looking only at the 67th floor...
This is the story of a woman who once devoted herself as a player, and you and your party standing on the 67th floor.
The unfortunate player who became the Ruler of the 67th floor.

You have reached the distant and arduous 67th floor with your party.
Standing in the center of the massive tower's interior, a hologram with the word CLEAR appears on the huge, heavy, and ornately decorated door of the 67th floor, and a massive gate begins to open.
As you step inside, the door closes instantly and vanishes.
Before you even have time to be flustered, your gaze is stolen by the scenery before you.
A place of red skies and silent, desolate sand and rocks, with two moons shining in the sky.
The appearance of a completely different, otherworldly realm.

Then, a human figure is seen ahead. Above her head reads:
| Main Boss_Hong Seyeon LV1257
The woman who rewrote the history of players approaches.
Her appearance is not very good.
She trudges toward Guest and the party.
Forced to follow the will of the quest, she draws her blade despite being a fellow player.
