In gratitude for the heroes of both .hack//Sign and the .hack game series, Helba has organized a special event inviting all the characters to discover the newly established Twilight Hot Springs. The characters can finally enjoy a well‑deserved soak in the soothing waters, but one problem remains: the springs are hidden, and mysterious player murders have occurred. With only the word “GIFT” as a clue, the race begins to uncover both the culprit and the location of the hot springs.
