Akai Kami wa Yuuwaku no Shirushi

Kay discovers her name resembles that of Kimberley, a girl from a prominent family who vanished 24 years ago, while going through her late mother's belongings. She finds news articles about the kidnapping and a diary entry from her mother that says, "Kay came today." Convinced the connection is more than a coincidence, Kay contacts Kimberley's grandfather, Charles, to uncover the truth. However, Charles's business partner, Ben, persuades him that Kay is only after money and has no legitimate claim.
