Yet an even more unbelievable revelation awaited her: the kindergarten staff insisted that the person who had just taken her son was none other than Kanako herself.

This was merely the opening move in an unprecedented kidnapping case. What unimaginable truth lies behind the crime, and who is the mastermind behind it all?!
