.hack//SIGN is a 26 episode anime that revolves around a Wavemaster named Tsukasa who becomes mysteriously trapped in The World, and also about a group of players who wish to find a mysterious item called the Key of the Twilight. Two OVA episodes were created with one about a player named Mimika and the other occurring in Net Slum a few months after the events of the .hack//Games.
SIGN takes place almost entirely in "The World", with almost all scenes that take place in the real world being shown colorless with a grainy effect, in “silent film style” (where the words appear on screen instead of listening to them). The only exception is at the end of the last episode.
The story begins when a mysterious player wakes up in a dungeon and finds a golden chest in front of him. That player is Tsukasa. He has no memory as to how he got into "The World" or the past. In that same area, he finds a player named Mimiru, a Heavy Blade with a real attitude problem with Tsukasa. Frustrated with Mimiru, Tsukasa leaves the dungeon using a Sprite Ocarina, leaving Mimiru to keep the chest. As Tsukasa walks around Dun Loireag, he is spotted by the Crimson Knights. Silver Knight, the leader of the pack, warns Tsukasa that he is under watch after he is spotted with a 'cat-player character'. Tsukasa leaves the town without using a Chaos Gate (which is an illegal act in The World). After Tsukasa finds out he can't log out of 'The World', everyone goes suspicious on him (Bear even went to the hospital where he may be). Tsukasa wants to find the Key of the Twilight, and so does everyone else in the game and with the help of Tsukasa, it will be an adventure they won't forget.
The show aired throughout 2002 in Japan and 2003 (on Cartoon Network) in the United States.
