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.
She said she was sorry 
for keeping you so late.
.اعتذرت على إبقائك لوقت متأخّر
Sie hat sich entschuldigt,
dass du so lang dort warst.
Elle s’est excusée pour l’heure.
Tu lui as dit au revoir, j’espère ?
Si è scusata per averti trattenuto fino a tardi.
Pediu desculpas por te
fazer ficar até tão tarde.
Сказала, что ей жаль, 
что ты так поздно ушёл.
