Professor Hope is also known as Dr. Grain. He was born to a family who operated the Grain farm, but when he was young his parents were killed in a boating accident. In school he showed great talent in many fields, including biotechnology and human engineering. He invents various agricultural machinery. The woman he loves/his sweetheart falls ill due to unknown circumstances (possibly due to his experimentation in agricultural machinery) and he begins to doubt modern agriculture. Following the incident, he refuses to work and resides in a villa near the lake.
