 As a special bonus for the fourth and final volume of the game  series, Bee Train and CyberConnect2 (the companies who produced  .hack//SIGN) created a bonus 29th episode entitled .hack//GIFT. In  addition to a redesigned opening and a plot which features the  characters from //SIGN and the games looking for a secret area  called the Tasogare Onsen (Twilight Hot Springs), the episode  contains radically different and cartoony designs for the characters  that exaggerate their physical features.
