Miyoko Tanashi lived a charmed life with her parents, but after losing both of them in a devastating train accident, the life she knew was suddenly ripped away. Sent to a secluded orphanage in the mountains, she is subjected to inhumane abuse at the hands of her caretakers; escape is not an option since runaways are met with a fate far worse than death. But eventually, Miyoko manages to flee and receive aid from her father's mentor—a researcher named Dr. Hifumi Takano.
