A lovely wallpaper featuring Tsucasa; .Hack//Sign's main character. Tsucasa is the central character of the series; the one from whom most of the story's mysteries stem from, and fixate upon. While nearly all of the characters mature emotionally throughout the story, Tsucasa has a particularly heartwarming transformation, as he slowly emerges from his shroud of sorrow and introversion, and opens himself up to the other characters, who then have a very lasting and meaningful impact upon him.
