Chapter Divider 1
ONIGUMA AND THE MAIDEN OF NINANNAH Long ago, we descended upon this land. This plentiful earth brought about an abundance of fish, grains, and fruit. All of these riches, however, belonged to the god of the mountains, Oniguma. Oniguma soon became enraged and devoured humans to satisfy its hunger. Then, one day, a maiden from the land of Ninannah stood upon and offered herself to Oniguma. Oniguma's hunger was quelled and it took her in as a wife.

Trivia

 * In an interview with Oima Yoshitoki, Oima said that each volume cover depicts a character's dream. The Boy's dream was to leave his village and see the world, so volume 1 shows him traveling with Joan.
