Mayumi Santou

The daughter of a wealthy family, Mayumi suffers from a mental illness whereby she must be given specific instructions at all times as to what to do or say; otherwise, she will be crippled by indecision and unable to do anything for herself. If she is not given instructions, she will constantly ask what she should do. Her father has hired several maids to look after her but they always resign, as they cannot deal with Mayumi's incessant questioning.
