Naoto and Naoya visit their old home only to find things to be not quite as they remember. Things become even more curious as they become involved in a case dealing with a school and its twisted teachers and suicidal students. After solving the mystery behind that remorseful situation, the two brothers learn a fraction more about the state of the world and their place in it. There is no time for reflection, however, as premonitions of death and disease come to light and new riddles require unraveling.
