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.
Come on, don't you want to know why
you're the only one who hasn't taken ill?
هيّا، ألا ترغب في معرفة 
لم أنت الوحيد الذي لم يمرض؟
Sag, möchtest du nicht wissen,
warum du als Einziger nicht erkrankst?
Vamos, ¿no quieres saber por qué eres
el único que no se ha enfermado?
Dis, tu ne veux pas savoir
pourquoi tu n’es pas malade ?
Como? Não quer saber o motivo
de ter sido o único que não adoeceu?
