To show gratitude to the heroes of both the .hack//Sign and the .hack game series, Helba has organized a special event for all the characters to discover the newly established "Twilight Hot Springs." The characters can enjoy their well-deserved rest and relaxation by soaking in the wonderful hot springs, but there is only one problem—the hot springs are hidden, and there have been mysterious player murders. With the only clue being the word "GIFT," the race has begun to find the culprit and the location of the hot springs.
