Thanks to her acquaintance's suggestion, Rika Musashi began her work at one of the elite schools called Akai High School as a teacher. When she met the principal, Tousaku Akagi, she was given an additional task: to find some 'traces' of a girl who had disappeared three years ago. In addition to this assignment, Rika also realized some unusual things. The difference attitude received by the student council president between his classmates and other students, the defamation action hidden by one class to several teachers and students, the 'appearance' in certain places, and not to mention, the 'mask' that was put on the whole face in Akai.
In that situation, Rika must be able to 'see' everything and not be carried away by the current problems to resolve the case before the incident repeats itself.
