Get married and I kill you. This was the letter sent to Kimihito, an ordinary guy living with a houseful of extraordinary beauties, by a mysterious writer known only as "D."

Meanwhile, Kimihito's potential brides each begin acting strangely. Are they taking the fake dates too seriously - or is something (or someone) far more sinister at work?
