Nogi Hideki (乃木 英樹, Nogi Hideki; "Hideki Nogi") is the CEO of Nogi Group and the newest Chairman of the Kengan Association.
Nogi Hideki is an esteemed looking gentleman, always seen wearing the finest threads. He has black hair that is slicked back and wrinkled yet experienced facial features.
Nogi is a shrewd individual with an experienced and cunning air about him. He has a good eye for noticing other person's useful qualities and manipulating them to benefit himself. As an experienced member of the Kengan Association, Nogi has a perceptive eye in regards to the fighting environment, being able to perceive and recognise the actions and movements of the fighters he observes. He is also sharp and cunning enough to outmanoeuvre and outwit an Association member of Hayami Katsumasa's level.
Having heard the story of Yamashita Ichinoshin and the vanishing Yamashita Family from his grandfather, as was the tradition in the Nogi Family, the previously indifferent Nogi was shaken when he discovered Yamashita Kazuo working at one of his subsidiaries five years prior to the most recent Kengan Annihilation Tournament. Remembering the last will of Nogiya Eikichi, "Find the Yamashita Family and repay them", Nogi decided to become the new Kengan Association chairman, with the preparation for it taking him five years.
Despite not winning the Kengan Annihilation tournament, Nogi was still nominated the new Kengan Association chairman and as such assumed the position of the previous chairman Katahara Metsudo as the Kengan's new head.
