Tanaka, who was leading a junior high life of excellence, swore to himself that he would make his high-school debut as a hot guy. He enrolls into a high school in which there is not one graduate from his old junior high, but on the day of school entrance ceremony, Tanaka sees students that can't possibly be thought of as humans... The "Sei Phlox Academy" that Tanaka enrolled in was in fact a school for non-humans, [Myuu], to learn, that is hidden from the human world!! Despite this, Tanaka still somehow attempts to make friends...
