The protagonist, a 17-year-old girl who was reborn after dying in her previous life at age 19. She discovered she was living inside a novel as the spoiled younger sister of the villainess in a 1970s military romance. Her family's fate was to die tragically to clear obstacles for the protagonists. After her consciousness awakened, she bonded with a nearly out-of-energy System that erased her harmful emotions but kept her memories. She returned to June 15, 1972 to prevent the tragedy. She is described as unbelievably lazy and terribly afraid of dying in her original personality, but determined and clever after rebirth. She saved the female educated youth from drowning herself to protect her third brother, and violently attacked the woman in the water to vent hatred from both lifetimes.
