Note

5 years after the world changed, the final boss appeared.

[The final boss for area Earth, the Frost Queen, has appeared.] The final boss! If we can just defeat her, our lives will go back to normal!
The top five players in the world, including Specter Seo Jun-ho, finally defeated the Frost Queen...

But they fell into a deep slumber.

25 years passed.

"A second floor? It didn't end when the Frost Queen died?

Specter awakes from his slumber.
