Rag Uralo commands the Sand Rats bandit group in the desert wastelands of planet Zola. The Sand Rats discover protagonist Jiron Amos and aid him in stealing the mecha Xabungle from trader Carrying Cargo, executing a plan that includes kidnapping Cargo's daughter Elchi. Upon integrating into the landship Iron Gear's crew, Rag maintains an active combat role, fighting on foot and piloting Walker Machines with mechanized warfare proficiency. Her personality remains bold and unrestrained, with scenes featuring partial nudity aligning with her narrative role as fanservice.

Rag develops unreciprocated romantic feelings for Jiron Amos early on, creating a love triangle with Elchi Cargo that results in Jiron physically restraining her during confrontations. Mid-series, she abandons the Iron Gear crew after becoming involved with a subordinate of antagonist Kid Horla. This relationship concludes when her love interest dies battling Horla's forces, prompting Rag's return to the Iron Gear.

Her character displays vulnerability following failed romantic pursuits but consistently resumes her fighter role in the Iron Gear's rebellion against the Innocent. The series finale resolves with Rag remaining part of the crew post-conflict. The compilation film *Xabungle Graffiti* presents an alternate ending where Rag claims Jiron as her romantic partner after Elchi departs with Arthur Rank.
