Halara Nightmare is the Forte Postcognition Master Detective in Master Detective Archives: RAIN CODE. She (final answer, take it or leave it) is the assistant in the first chapter. Halara is a ruthless and uncooperative jerk who constantly asks for money and she has no mercy for those around her. She's also unable to change her emotions and has no issues with taking things to extremes, and also constantly insults those who surround her life. There is still good in there, however.
