General Agemaki, the father of Kei is one of the most powerful Generals of the Imperial Army. He came through many impossible wars and thus earned the title 'Veteran Agemaki'.

He is partially to be blamed for Kei being too scared of spirits. He had always been strict with Kei. As a result, Kei has always been uncomfortable around him. He is the one who recommended Kei to be assigned to the Ministry of Spirit Affairs.

General Agemaki is very fond of western culture and believes in a Modern Japan where westernisation should be welcomed with open arms. He hates spirits.
