Sakuya, a princess from a distant land, flees her threatened homeland alongside fellow princess Milte. Their escape ends in capture by a notorious pirate commanding a vessel equipped with a torture chamber. This pirate specializes in sexual training methods and subjects both captives to erotic torture and psychological torment. Specific ordeals include a forced encounter with an octopus and the humiliation of being covered in roaches. Throughout the captivity, Sakuya attempts to endure the violations, including the loss of her virginity to the pirate, as a survival strategy. This approach contrasts sharply with Milte's overt resistance. The narrative provides no extensive backstory regarding Sakuya's homeland, family, or specific royal status beyond her princess title. Following these central events, Sakuya's character receives minimal development or resolution. The story's conclusion focuses more on Milte's dynamic with the pirate, leaving Sakuya's fate and personal journey unresolved and unexplored. No official media expands upon her background, development, or experiences beyond this primary OVA storyline.
