An alien named Yoden arrives on Earth carrying a mysterious tool called the Ability Gun, a device capable of extracting and injecting the special powers of any living creature. Yoden's mission is deceptively simple: use the powers gathered from across the cosmos to rewrite the destinies of Earthlings, steering them toward happiness. This plan quickly spirals into chaos when a young Earthling named Sango is caught up in the alien's experiments, and a beautiful extraterrestrial woman named Kyuuka appears, bringing her own agenda. The Ability Gun attracts the attention of a shadowy alien syndicate that will stop at nothing to claim it, drawing Yoden, Sango, and Kyuuka into a series of unpredictable confrontations. Each skirmish forces the characters to wield—or be subjected to—an ever-shifting roster of borrowed abilities, turning allies into wildcards and battles into comic mishaps. The central conflict revolves around whether Yoden's well-meaning but reckless power-granting can truly improve lives before the pursuing spacefaring criminals capture the Ability Gun and use it for their own sinister purposes.
