Frieda, a young heiress, becomes ensnared in a perilous web of intrigue after a radium mine is uncovered within her grandfather’s forsaken estate. Her 1905 abduction by foreign operatives ignites a ruthless contest between factions: a profit-hungry American opportunist, a Polish revolutionary concealing his identity, and Apfelland’s ministry scheming to forge ties with Germany. Rescued through an unlikely alliance between a roguish thief and a dogged inspector, she is thrust into a treacherous geopolitical arena. Possessing sole knowledge of the mine’s location and its volatile strategic significance, Frieda emerges as the linchpin in Apfelland’s fight for sovereignty. The narrative traces her navigation of betrayals and shifting loyalties as she races alongside allies to expose the mine’s secrets, though her personal history beyond her grandfather’s legacy remains unexamined. Her story is documented exclusively in the 1992 OVA, with no sequels, spin-offs, or expanded universe materials attested.
