Setting: It was happened in a long time ago that the narrator doesn't remember about that much. In an old but industrialized city.
Conflict: The thing was lost. And no one knows about him. Protagonist's parent asked their son to take the thing where he was but he doesn't know where to take "the lost thing."
Climax: Together with the boy, "the lost thing" found the place where he belongs to.
Symbols: Protagonist, the boy, was looking for the place where "the lost thing" came from. But I think that is a symbol for him looking for his identity not only "the lost thing". Though he has parents and friends, I think he is looking for the place where he really fits in.
Irony: What is ironic about this story is that he doesn't remember the incident that much. As the experience was very vivid, he doesn't remember it.
Theme: Theme for this animation is "memory could be faded away." As I said in "irony" part, he doesn't remember much about the incident. That is not only the matter of time. His attitude towards memory made him to do so. We have to do something in order to keep our memories in our heart like writing a diary and taking pictures.
