Ogata is the former Superior Private of the 7th Division and a member of Hijikata's Group.
Ogata has black hair that is shaved at the sides in an undercut fashion, a thin beard, and dark eyes. He sports a suture scar on each cheek, acquired after he fell from a cliff and broke his jaw while running from Sugimoto.
He is analytical and ruthless, a proud sniper who is used to examining things from afar and evaluating circumstances in order to best take advantage of them. Even when at a disadvantage, Ogata keeps his nerve and takes the most advantageous course of action.
He has a habit of slicking his hair back. He seems to be a very proud man as he would attempt to do a task that someone says would be difficult for him and puffs his nose when praised.
