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.
And since I thought Ohana-san 
might not like me like that,
وعندما فكّرتُ أنّ أوهانا-سان
،لن تحبّني على تلك الحال
Ich dachte, Ohana-san würde
so keinen Gefallen an mir finden,
Y como creo
que no le gustaré a Ohana-san así,
Y como creo
que no le gustaré a Ohana-san así,
Pour éviter de déplaire à Ohana,
j’ai commencé à sauter mes repas.
Ho pensato che di questo passo
 non le sarei più piaciuto,
E como achei que a Ohana-san
não iria gostar de mim assim,
Вот я и подумал, 
что Охане таким не понравлюсь,
