It is the year 2121, a world where everyone has mutated, varying from simple mutations such as purple eyes, to having abnormal super human powers, but there are a few late bloomers, and some who don't gain any special abilities at all. Those who aren't mutated or do not gain power from their mutation are often treated like trash or even killed off.
To restore balance and some sort of power control, all those below 20 are obliged to go to school and wear P.E.Ts (Personal Electronic Trackers) that monitors your every move. They will teach students to control their powers and also learn how to treat each other accordingly without using their powers against each other.
In a world where human rights are a blur and power means everything two groups of people have formed societies: ones who wish to eradicate the weak and leave only the strong to do as they please, and ones who wish to restore balance, let those without power live without fear. The player was in one of these groups, but he/she was betrayed and murdered. As you were in the land of the dead, someone granted you a chance to take control of a non-mutant student who committed suicide, with a catch that you will not remember who killed you and what got you killed.
The player accepts the catch but is shocked to find out he/she isn't the only one in this body - the original owner is still alive there and you're both gonna have to share control. Will you be able to balance out both student life and the life of a rebellion? Catch your killer? More importantly, can you get a body of your own?
