Nanoka's life changed forever on September 1, 2011, when a massive explosion killed her parents while they were driving to visit her hospitalized grandfather. The blast threw her clear of the car, and her last coherent memory before waking in the hospital is fragmented—a burning landscape, a creature gripping a severed head. She learned the truth about her parents' deaths while recovering, and from then on lived with her grandfather and his live-in maid, Fune Uozumi.
Growing up, Nanoka was told she was sickly and frail. The bitter green drink she was forced to take daily supposedly kept her weak body functioning, though she never questioned it much. Eight years later, curiosity got the better of her. She decided to investigate the explosion and the strange sinkhole that had swallowed her parents' car, returning to the accident site to dig up answers.
That's when things got weird. Walking past a gate near the crash location, the modern street vanished and transformed into a bustling 1920s shopping district. It was there she met Mao, and the pieces finally started coming together. The explosion wasn't random—it was collateral damage from a supernatural battle between Mao and a demon named Byoki during the Great Kanto Earthquake. The shockwave tore through a time portal and hit her family's car on the other side.
Nanoka discovered she'd been caught in the crossfire that day, dragged into the past and cursed by Byoki just like Mao. She carries the demon's blood in her veins. The green drink her grandfather forced on her all those years? It wasn't medicine. It was a suppressant, meant to seal away her demonic powers so she wouldn't attract Byoki's attention. But the demon is still out there in the modern world, hunting her down, convinced that merging with her will restore his stolen strength.
