The guy really likes being like everyone else. Therefore, when a new student, Aya Otonashi, transfers to his class on March second and declares war on him from the very start, Kazuki's usual life is shattered in an instant... Aya is convinced that it is because of him that she has to relive the same day over and over again. But even if such a thing is possible, how can he, an unremarkable student, be to blame for this?..
