Yūsaku Kudō features as a central character in two segments of the second OVA collection. In "The Wandering Red Butterfly," he takes the role of a detective persistently summoned by calls from a mysterious woman, driving him to resolve new cases and highlighting his deductive skills and ongoing investigative work. "The Ten Wandering Stars That Fly Through the Night Sky" expands his narrative into a family dynamic. His wife Yukiko Kudō actively searches for him, framing his absence as a key plot motivator, while their infant son Shinichi Kudō appears, cementing Yūsaku’s familial role where his presence or absence directly shapes events. The adaptation of "The Wandering Red Butterfly" deliberately replaces the original manga’s characters with Yūsaku and Yukiko Kudō, connecting the story to Gosho Aoyama’s broader universe. This substitution anchors Yūsaku in scenarios recognizable to existing audiences, reinforcing his detective persona within novel narrative contexts.
