| Summary | In a bustling household, young detective prodigy Ryusuke Haruta receives an enigmatic invitation from Dr. Metras, a renowned American criminologist, to celebrate his investigative triumphs. Despite reservations about missing his father’s groundbreaking submarine test, Ryusuke attends—only to walk into a trap orchestrated by Charlie, a vengeful mixed-race ally of a former adversary. A violent confrontation erupts in darkness, gunfire echoing as loyal friends Sota and Fumiko race to uncover the truth from afar. Meanwhile, shadowy forces hijack the experimental submarine, spiriting it toward the mysterious Skeleton Island, a clandestine base rigged with explosives. As Ryusuke battles betrayal at sea and uncovers Dr. Metras’s sinister ties to foreign espionage, Fumiko is kidnapped, and time ticks toward a cataclysmic detonation. With naval destroyers closing in and alliances tested, Ryusuke must outwit ruthless foes to save his family and prevent global chaos—but Skeleton Island’s secrets threaten to drag all into the abyss. |
