Sōichirō Kiryūin

Sōichirō Kiryūin (鬼龍院 総一郎 Kiryūin Sōichirō?), also known by his alias Isshin Matoi (纏 一身 Matoi Isshin?), was the husband of Ragyo Kiryuin and father of Hayate Matoi, Ryuko Matoi and Satsuki Kiryuin. He was a brilliant scientist and Life Fiber researcher who went on to create Senketsu, the Scissor Blades, and Nudist Beach. He was murdered by Nui Harime along with Ragyo Kiryuin's descendants; including, Lord Shen Kiryuin thinking Hayate Matoi is murderer of the Series. He is impaled by his own Scissor Blade.

Sōichirō had aimed to "thwart the return of the Galactic Empire led by Dr. Robotnik by using the Kamui". His actions are the posthumous driving forces behind the plot of the series—including Ryūko's search for her father's killer.
