Detective Conan: Episode "ZERO": The Shinichi Kudo
It's a little while before Shinichi Kudo swallows that mysterious drug from the Black Organization and becomes “Edogawa Conan.” Back when he and his childhood friend Ran Mōri were still just that—friends, not yet a couple—the two of them are visiting Beika Aquarium. Their real reason for being there: scouting the perfect spot for “Operation Aquarium Surprise Reunion, Rekindle the Romance!”—a scheme to get Ran’s separated parents back together.
