Due to his old age, Sougen has grey hair that is combed and gelled to the right. He also has yellow eyes and a moustache.
Sougen is seen wearing a white shirt that is unbuttoned on the top and grey dress pants. Underneath, he wears a maroon turtleneck and a black blazer over it. He carries a cane to aid him in walking.
Sougen is a strict person as seen from teaching Hiragi Tsubasa to be the heir of the Hiragi family. He is also seen to be very indifferent as he told Hiragi to forget about his real family as he is now a member of the Hiragi family.
Otori family is a branch of the Hiragi family and Hiragi was originally part of the Otori family, going by the name Otori Tsubasa. One day, Sougen appointed Tsubasa as the heir of the Hiragi family. Tsubasa had to be separated from his family and live with the Hiragi family.
