Hanzou Masanori Hatsutori

A relative of Shimo-no-Hanzou Hattori, this Hanzou is from the Hattori clan of Okazaki in upper Iga, hence his being referred to as Kami-no-Hanzou (上の半蔵 "Upper-(Iga)-Hanzou") to distinguish him from the other ninja also named "Hanzō Hattori" (including the historical Hanzō Hattori, who is Kami-no-Hanzō's father in this story). While he is a notorious playboy he is currently in a relationship with Sara, the daughter of Oda Nobunaga - this is a relationship his father reservedly accepts, not only because (as the manservant of Tokugawa Ieyasu) the Hattori clan is current warring against her father, but also her father's aim to obliterate all ninja in Japan. In Volume 7, he told her that she couldn't go on the assignment because she was pregnant. Hanzou compares him to Hikaru Genji from The Tale of Genji, in Volume 2.
