In this time, many terrifying individuals who care nothing about freeing themselves, and others, from the game roam. These are the Player Killers. However, among their number is a mysterious character, who is rumored to be able to defy the laws of the game. Though considered to be nothing more than a mere rumor, one player, known to all as the Terror of Death, actively seeks them out.

However, when Haseo finally encounters this illusive PKer, he is easily defeated...though rather than die in the real world, his avatar's level has been lowered, and the majority of his inventory corrupted. Forced to start over, Haseo resumes his quest to hunt "Tri-Edge." In his quest, however, he comes across a powerful force that promises great power if harnessed.

Just what awaits Haseo in his quest as he hunts down "Tri-Edge?"
