Ogata is a tall man with dirty blond hair. He wears glasses over his sharp brown eyes, and is usually dressed in a white suit when playing. Sometimes he is seen smoking cigarettes at home. Altogether, he is in the very image of modern Japan - living hyper-modern yet playing a strategy game thousands of years old.
A fiercely focussed man, Seiji has a tendency towards obsessing over things, especially whenever they do not make sense to him or he does not have all the facts, much to the distress of Shindou. He likes dissecting puzzles, and often overthinks, which once cost him the Honibo title. Having been born in between the "great waves" of the Japanese Go world, Ogata is somewhat title-crazy, seeking to welcome the younger generation as title-holder. He thus has a heavy rivalry/war going with Kuwabara Honibô about the latter's title, who refuses to give it up.
Not much is known of Ogata Seiji's history, but it should be noted that he entered the Go World in a time of relative calm, where people like Kouyo Touya and Kuwabara dominated the field. Eventually, he became the student of Touya.
Being the most senior student of Touya Meijin, Ogata is an accomplished professional of his own, as evidenced by his 9th Dan rank. His go has been described as spirited, analytical and inspired. He hates to lose, and will often fight until the bitter end.
