Mai Nakahara
Mai Nakahara, who plays Nanami, and Kana Ueda, who plays Sango, humorously talked on a radio show as their characters. A few years later, in a post announcing a DVD of these records said that Nakahara and Ueda's "logbooks," which aired from November 4, 2005 to June 30, 2006, before the show began airing, were "extremely popular."
