In a world where humans, demi-humans and monsters co-exist, Shizuka Yakou is a quiet and bashful woman who works at a small detective agency. Her employer, Tounome, is the refined and courteous owner of the agency, who possesses the unusual ability to turn invisible. While his power is invaluable for investigative work, it proves ineffective on Yakou, who is blind, yet can always sense Tounome's presence. Intrigued and charmed by her perceptiveness and gentle nature, Tounome develops romantic feelings for her and begins looking for opportunities to grow closer. As Yakou navigates her daily work, she is supported by the agency's eccentric staff, including Kikira, a blunt and unsociable human man, and Jarashi, a warm and protective beast woman.
