This story is about a girl named Kathryn who suffered with a condition called achromatopsia that made her see the world in black and white. One day, two people came into her life, namely Reina and Shawn. These people changed her life in a different way than she had imagined

The new semester opens with a bang that shocks the four Houses of QED University, an exclusive school for promising students of the science of deduction and art of detection. The Holmesian Harriet Harrison never thought that the day would come when their archnemesis Moriartian faction beat them in the House War. Her competitive attitude toward her class rival Morrie Moreno intensifies, each trying to outsmart and outmaneuver the other. But trouble does not stop there. The most charming Adlerian Aiden Alterra commits himself to a "secret mission" and starts pestering Harriet. The seemingly mute Wilhelmina Williams from the Watsonian faction also gets dragged along with the three in a string of mysterious incidents that will plague the university. Despite their dissenting motivations and unique personalities, the four will have no choice but to work together as a team toward one common goal and against one common enemy. The classes begin.
