Rion Steiner

A boy who wakes in a hospital with no memory of who he is. The game suggests Rion gained psychic powers as a result of the human experimentation being conducted in the hospital. Led by the voice of a girl named Lilia, he escapes the hospital and begins searching for both Lilia and his identity. In the course of the game, it is established that Rion is a drug addict, and he is physically wasting away due to his constant exposure to various chemicals.

Rion's father wrote a program in Rion's mind that, when coupled with the virus program in Lilia's brain, can destroy the mother computer Dorothy.
