Treasure hunter Riot Genus scours the ruins of a fallen civilization in a post-apocalyptic world, often aided by charming companions. His singular obsession is securing the legendary artifact called the Eyes of Zalem. This artifact is the crucial means to locate the Rido, a fabled treasure from the lost Quall civilization rumored to be a source of limitless energy capable of restoring life.

Riot's relentless pursuit of the Rido stems from a deeply personal mission: to resurrect his deceased sister. This goal fuels his every action and brings him into direct conflict with the antagonistic Demsters, who also seek the Rido's power. The Demsters actively obstruct his quest, resulting in repeated confrontations. These battles involve strategic clashes, mecha combat during key engagements, and personal fights where Riot wields a distinctive whip-like weapon fashioned from an arm bandage.

Riot Genus operates as a determined adventurer focused entirely on acquiring the Rido to achieve his resurrection objective, constantly navigating the threats posed by the Demsters within the harsh post-apocalyptic environment. His characterization emphasizes his skill, cunning, and resolve in this ongoing race against ruthless opposition.
