Takeshi's friend tells him a rumor about a ghost that wanders, looking for a collar. When he gets home, he finds an old collar there! That night, the ghost of a young girl appears before him, and he learns that the ghost is looking for her dog, Shiro, who she lost during a bombing raid during the war.

Pochi appears in front of Tama wearing a strange, old collar. Pochi seems different than usual, so Tama follows him and ends up in a field he's never seen before. There, Tama learns that Pochi's been possessed by the ghost of a dog named Shiro who'd lost his life in the war.
Until that time comes, I will 
continue to wait here, forever.
.إلى أن يحين ذلك الوقت، سأواصل الانتظار هنا إلى الأبد
Bis dahin werde ich hier warten.
Hasta entonces, esperaré aquí.
Alors je bougerai pas
jusqu’à ce qu’elle vienne.
Fino a quel momento, continuerò
ad aspettare qui per sempre.
Até chegar essa hora, vou
ficar esperando aqui, para sempre.
И я готов ждать вечно.
