Conan and the Junior Detective League participated in a football training session led by a professional player-turned-coach. During the event, Kogoro reunited with Ryosuke Sakaki, a college junior who now coaches a youth football team. Sakaki introduced Kogoro to Keiichiro Honpo, a sponsor of the youth team and an admirer of Kogoro’s work. Honpo, deeply passionate about football, had tragically lost his son, Tomofumi, to illness. Other attendees included Shinzo Yamamori, a television producer at Nichimai TV; Kaoru Koda, a journalist; and Kazuma Nakaoka, a former football player sidelined by injury, preventing him from joining the J-League.
