Rogane, also known as Koganemaru Matsushita or Koganemaru, is the son of an intergalactic quadrillionaire. His kidnapping forms the central plot driver. Distinguished by a headband signifying his immense wealth, his family's fortune makes him a prime ransom target. Investigation exposes the kidnapping as Rogane's own elaborate scheme, orchestrated with Sue, Maris's wrestling rival, who poses as his captor. He sought escape from his privileged existence through staged criminal excitement. Their partnership deepens into genuine affection. After the kidnapping plot unravels, Rogane rejects Maris's anticipated rescue-marriage scenario by proposing to Sue, prioritizing emotional fulfillment over dynastic duty. This choice directly causes Maris's financial loss and emotional downfall, nullifying her expected reward and marriage plans. Rogane's arc concludes with a deliberate rejection of wealth-centric societal expectations in favor of personal happiness. His background is exclusively detailed within the 1986 OVA adaptation.
