Miyu Izawa is a designer working for the prosperous Studio Yo in central Tokyo. She is nicknamed "famous detective" because of her unusually sharp perception: since her childhood, she has possessed an inexplicable "sixth sense" that warns her of danger by coloring her vision red. When her former classmate and successful model Marie is brutally murdered, Miyu decides to use her special senses and investigate the mysterious circumstances of her death.
