Rags Town is the garbage dump of Japan. The place where people who want to forget their pasts run to. In this town, where the rules strictly forbid asking about the past or getting to know people, there is small detective agency called S&A Detectives. The story revolves around Ayamana, the inseparable pair of misfit wannabe detectives, the case Manami takes on impulse, and the trouble that arises from it. On the case they find a woman who is abnormally hot, and who is being chased by a bunch of women with guns. After being dubbed Sara, the detectives try and figure out just what is going on with her. At the same time, all over town teenage girls are burning up and turning into glass. The government is covering everything up, but the detectives, as well as a nosy reporter and the local police, are determined to find out what is happening.

The stage is the close of the Edo period, an age when, not unlike our own time, both natural and man-made disasters left chaos in their wake. Manjiro makes a living helping the people of the troubled capital city, but behind the scenes, he also works in secret to take back precious belongings stolen from the people by unjust political powers and conspiratorial menaces. The people call him "Get-backer Roman."

Based on the RPG game of the same name. Aurica Nestmile is a young Reyvateil, or "singing maiden" who feels her song magic is not of much use to anyone. From high up on the tower Ar Tonelico comes Lyner Barsett, whose airship is totaled upon impact with the ground. These two meet up, and in the search for someone who can repair the ship, end up helping both each other and themselves.

As an expression of gratitude for the heroes of both the ".hack//Sign" and the ".hack" game series, Helba has prepared a special event for all the characters to find the newly established "Twilight Hot Springs." The characters can get their well deserved rest and relaxation by having a soak in the wonderful hot springs, but there is only one problem—the hot springs are hidden and there have been mysterious player murders. With the only clue being the word “GIFT," the race has begun to find the culprit and the location of the hot springs. [Written by MAL Rewrite]
