8th Seat of the Fourth Division as well as the second leader of the first relief team. Harunobu has dark brown hair with seemingly no part and soft skin. He has brown eyes and wears the standard Shinigami uniform, with a rope strap that connects the relief pack on his back. He has had little speaking roles in the anime or manga. However, he seems dedicated to his work, as he is often seen leading his First Relief team around the Seiretei. He and Yasochika Iemura also annoy each other, leading Iemura to draw his Zanpakuto once. He is shown to be very popular with the ladies as most of the 4th Division's mail is addressed to him from the women of the Soul Society and is also a member of the Shinigami Men's Association.
