Miyako is married to the president of Ichigo Productions and is Ai's manager. She is a shallow woman who appears to have only married her husband due to the prospect of working with hot guys. She is also a babysitter to the twins.

Spoiler

After Ai's death, she becomes the twin's adoptive parent. As the twins blossom into adolescence, she becomes more mature, both as a caretaker and as a manager. She is also the manager of the new B-Komachi.
