One morning, Seiji runs into Kounosuke while out on a walk. The two young men discuss recent affairs on Ryogoku bridge, but Kounosuke suddenly loses his balance and falls in the river, accidentally pulling Seiji with him and losing his precious seal box, Kogare-kou, that has been passed down in his family for generations. Kounosuke does his best to look for it, but to no avail. Meanwhile, another young man appears to have found Kogare-kou and demands a considerable sum for its return. With Kounosuke facing being disowned by his family if he cannot get the object back, Seiji and Oko do their best to help him raise the money with the help of the tsukumogami.
But who would have exchanged 
that with something better?
لكن من يكون قد استبدل ذلك بشيء أفضل؟
Aber wer treibt solche Tauschgeschäfte
zum eigenen Nachteil?
Pero ¿quién daría algo mejor
a cambio del peine?
Pero ¿quién nos cambiaría
algo que sea mejor?
Mais qui va accepter
une telle transaction ?
Ma chi mai scambierebbe un oggetto
 con qualcosa di meno costoso?
Mas quem iria trocar isso por algo melhor?
Но кому захочется отдавать
 хорошую вещь за обычный гребень?
