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.
I'm sure Sataro-san's mother 
showed it to you the other day,
أنا واثقة أنّ والدة ساتارو-سان 
،قد أرتك إيّاها في ذلك اليوم
Satarou-san hat ihn dir doch
sicher letztens gezeigt, oder?
De seguro la mamá de Sataro-san
te enseñó el otro día
Seguro que la madre de Sataro-san
te enseñó el otro día
Sono sicura che la madre del signor Sataro
 sia venuta qui l'altro giorno
Tenho certeza que
Sataro-san mostrou a você
Наверняка мать Сатаро 
уже показывала тебе...
