He is a figure within the cult known as "the Order of Silence and Darkness". Shijima can become the Dummy Dopant who can assume any form he wishes. Among these forms is the Death Dopant, using his powers to mimic the real Death Dopant's ability to bring people back from the grave. Using the Death Dopant's form, Father Shijima targets upper class people by assuming the forms of their recently deceased relatives to frighten them and push them to an early grave. However, the Dummy Dopant meets his end when he is assimilated by the Neo Organism as it becomes the inhuman Ultimate D.
