In the year 2005, a computer virus called Pluto Kiss destroys the networks of computers all around the world, subjecting the cyberspace to severe restrictions. Two years later, as free access to the networks recovers, people are now crazed over a full-immersion virtual gaming environment called The World.

However, when reality and virtual reality collide, a whole new adventure unfolds as a mysterious accident leaves Wave Master Tsukasa permanently logged in. Now a group of ciphers must figure out the truth behind Tsukasa while a rash of mysterious game-related incidents in the real world begins to draw the attention of even the most powerful players within the game.

Tsukasa has been captured by the Crimson Knights! Subaru talks with him and tries to understand his plight, but the unbalanced Sora stages a jailbreak. Tensions mount within the group as Mimiru confronts BT about her betrayal of Tsukasa.

Mimiru decides to give it all up, but after a chance encounter with another player, she changes her mind. As the clues unfold, everything points to a powerful legendary item called 'The Key of the Twilight'. Could this be the source of all the trouble in The World? Everyone seems to think so. Alliances are formed and plots are hatched with everyone's sole focus to uncover this item's location.
