The character known as Genesis' Victim, sometimes referred to as the Girl in the Sack, appears in the film Suicide Club. She is a minor but significant character associated with the antagonist Genesis and his group. No direct information is available regarding her personal background, such as her age, family, or life before the events of the story. Her personality and motivations are not explored or detailed in accessible sources. She functions primarily as a victim within the narrative, serving to demonstrate the cruelty and depravity of Genesis and his followers.

In her key scene, which takes place inside a bowling alley where Genesis and his rock musician cohorts are holding the hacker Kiyoko captive, the girl is brought out inside a bag or sack. Genesis then steps on the bag, killing her in a brutal manner, as part of a performance or display of power. Her role in the story is therefore to be a victim of a heinous act, used to establish the threat posed by Genesis and the disturbing atmosphere of the film. Her only key relationship is with Genesis and his group, as she is their victim, and her death directly affects the captive Kiyoko, who witnesses the event. There is no information about any development the character undergoes, as she is killed shortly after being introduced. She possesses no notable abilities, as her significance is derived entirely from her function as a helpless victim in the plot.
