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.
Then, someday, fulfill
the promise you made to me.
.إذًا يومًا ما، نفذ الوعد الذي قطعته لي
Entonces, algún día,
cumple la promesa que me hiciste.
Alors je veux qu’un jour,
tu fasses ce que tu m’as promis
Então, algum dia,
cumpra a promessa que fez para mim.
