GetBackers

Ban and Ginji are hired to recover a stolen briefcase by a man, named Mr. Sasakida, who explains that he thinks a group of teenage girls took it. To find it they must deal with a high school girl, named Riko Tachibana, who ignores Ban and Ginji. She then claims to know where the briefcase is, by payments of an "informant fee". They treat her to dinner, shops for her clothes, and buys her jewelry. Furthermore, they are forced to ask Shido, Kazuki and Himiko to treat her, but they all end enraged at her. She eventually takes them to a garbage heap, where Kazuki, Shido, and Himiko assist Ban and Ginji in rummaging through the junk to find the briefcase, which eventually turns out to be empty. Riko then tells them that it was empty from the start, as it was one of Riko's friends that threw the briefcase in the garbage. Although, in the briefcase, a disk is contained. Sasakida returns with a group of men in black, who demand to return the disk to them. Riko is taken hostage by the men in black, who then are summarily defeated by The GetBackers. Akabane shows up after because apparently he was hired to transport the briefcase. Mr. Sasakida explains that he got demoted from his job for a co-worker's mistake, and he would have been promoted to his job if he made a deal with the men in black. The GetBackers forgive his acts of crime and return the disk to Mr. Sasakida. Akabane and Riko befriend each other, as they exchange email addresses. Kazuki, Shido, and Himiko chase Ban and Ginji down for involving them with Riko.
