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

Use Kimihito as bait by sending him on a series of dates with monster girls. Along the way, several possible suspects emerge, each of whom has a 'D' connection of one kind or another. 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?"--Page 4 of cover.
