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.
Yeah. Let's return the collar 
to that air-raid shelter!
!أجل. فلنعد الطوق إلى مأوى الغارات الجويّة ذاك
Ja, wir sollten das Halsband
zum Bunker bringen.
Sí, vayamos allí y devolvamos el collar.
Oui, allons poser ce collier
dans cet abri.
Sì. Riportiamo il collare
in quel rifugio antiaereo!
Sim, vamos levar de volta a
coleira para esse abrigo antiaéreo!
Ага. Вернём ошейник 
в это бомбоубежище.
