Tokyo

The story is about a young woman (nicknamed 'Grey' by a fellow patient in a mental hospital) who is obsessed with the 1937 Japanese invasion of Nanking, also known as the rape of Nanking. She travels to Japan in order to find a professor said to have rare footage from the massacre of a baby being cut out of a woman's stomach by a Japanese soldier, and surviving. Grey is obsessed with this idea to the point she tried it out on her own unborn child (who did not survive), and also joins a Host Club in order to have an address and money in order to pursue the reluctant professor
