Two bodies with burned faces are found by the police; after facial reconstruction, they look identical to the wife of a plastic surgeon. The surgeon has performed several surgeries on his wife to make her look like his former love. When she discovers that her husband is seeing another woman, she kills her; when she discovers there is another woman who looks like her, she kills her too. After Neuro solves the mystery, Sasazuka says that Yako's mother was arrested after flying to South America.
