Live as if dead, or die as if living.
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?

He has a generally bright and friendly personality. He cannot stand to see people die, even if they are ReDeathers, and helps them escape. His ReDeath Loss is the loss of physical humanity, making him exceptionally difficult to kill.
