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.
Well, it happened a really long time ago.
.لقد حدث ذلك منذ زمن بعيد
Es ist ja auch schon ziemlich lange her.
Pues sucedió hace mucho tiempo.
Il faut dire, ça remonte à loin.
Bom, aconteceu há muito tempo.
