Gorou Yatagarasu, a young ICPO officer, serves as Inspector Koichi Zenigata’s dedicated assistant in the relentless pursuit of Arsène Lupin III. Tasked with strategizing operations and executing missions against Lupin’s heists, he operates as Zenigata’s right-hand man across multiple cases, though early portrayals in *Lupin III: Part 5* offered limited exploration of his persona. Subsequent appearances in *Prison of the Past* and *Lupin III: Part 6* gradually positioned him as a recurring figure within ICPO’s efforts, hinting at deeper narrative integration in future arcs.

During the Dorrente Kingdom infiltration in *Prison of the Past*, Gorou aids Zenigata in thwarting Lupin’s jailbreak attempt, showcasing his tactical involvement without delving into personal history. While his professional commitment anchors his role within the franchise’s law enforcement framework, official media remains silent on his origins, private motivations, or individual growth beyond duty. His persistent presence across installments underscores a steady, if underexamined, influence in the cat-and-mouse dynamics between Lupin and his pursuers.
