Akie Akashi

Considering how well she maintains herself, it is difficult to believe that Akie is Kaoru's actress mother who divorced Kaoru's father five years ago when Kaoru was delivered into B.A.B.E.L. stewardship. Considering the time frame, it is not that much of a stretch to surmise that Kaoru's father has either been driven off or killed by Kaoru's Level 7 telekinesis going out of control which frightens Akie right out of administrating over her younger daughter's childhood development in contrast to Minamoto actually setting limits for Kaoru -- and enduring the verbal and telekinetic objections thereof. Akie's inability or unwillingness to see Kaoru as her daughter that happens to be an esper leads her to behave a heavy emphasis upon her work.
