Yuko Kusaka, a Japanese journalist, travels to Brazil to report on a gold rush that is turning ordinary people wealthy almost overnight. Rumor says a Japanese man called Rio Baraki is among the prospectors working the Amazon. Soon after her team arrives, a crew member is attacked and she is sexually assaulted, a warning to drop the story and go home. She refuses to leave, and learns that her attacker is Baraki himself, a muscular, white-haired man with a huge scar across his back. His true name is Keisuke Ibaraki. He was once a quarterback with a bright future until a powerful organization called GPX framed him. Adapted from Kazuo Koike's manga, the five-episode OVA mixes action, adventure and ecchi content.
