Appearance
In contrast with the rest of the family, she is of an average height and slender build, with neck-length black hair.

Personality
From her son Manta's own opinions, Keiko is apparently a very shallow and superficial person. She told her son not to be friends with Yoh anymore because how it would look for a member of the family to be seen with a spiritualist.

Shaman Fights in Tokyo
After her son was injured by the shaman Johann George Faust VIII she visited him in the hospital. There she tried to convice him, not to see Asakura Yoh anymore, but was also concerned how people would see her, after the events with her son. Manta however chastises his mother's superficial attitude and runs away leaving her standing in the hospital with his sister.
