While traveling the wilderness, Mizuho asks Yamabiko how he became a dog. Yamabiko then relates how, 5000 years ago, he wandered different worlds all alone, until meeting a girl to whom he gradually opened his heart. But their happiness was short-lived.

C’était une mauvaise idée… Un vrai échec.
Eu não deveria ter tentado. Eu falhei.
