Oko has been on a never-ending search for the incense burner, Suou, that is deeply tied to a man named Sataro, who once admitted his love for her. Clues about the item has been hard to come by, but one day, while Tsukuyomi and Ohime are lent out to the Tsuru-ya, they overhear that another person is also searching for Suou. Upon hearing about the conversation, Seiji begins to think that the person might be Sataro himself and with a mixture of complicated feelings he starts to search out more information on this individual.
