Live as if dead, or die as if living.
About
Japan, 20XX. A disease called ReDeath Syndrome was spreading. It is an illness where the afflicted, upon receiving fatal physical damage, returns to life along with the loss of their humanity—a phenomenon that defies reality. A sufferer of ReDeath Syndrome who receives fatal damage a second time—a ReDeather—dies completely. Now that you have become a ReDeather, will you continue to live while dead, or will you search for a way to die?
