Remi Mochizuki has been aware of Sora Kitagami's extraordinary power since they were children. With just a touch, Sora can sense the thoughts and history of people and their belongings. Rather than being frightened by this baffling ability, Remi has made a conscious decision to always be truthful in order to remain close to Sora. Lately, however, her feelings towards him have started to change, presenting a challenge.
When Remi's biological brother, Keishi Mochizuki, a former police detective who now owns his own investigation firm, enlists Sora's help in solving the disappearance of Yukina Ueda, a young girl who bears a striking resemblance to Remi, both men are troubled. Sora confidently claims that the girl was killed by her older brother Masaki. If Masaki ever comes face-to-face with Remi, will he be compelled to commit the same heinous act?
