Full Name: Teruko Oyama

Sister of the head of the Oyama family. Used to live with Konoha, but now drifts around Ashihara as an unemployed camper. Since time flowed differently on Nini's space station compared to Earth, she's Nini's grandmother at a youthful 29 years of age. Her husband and daughter left for space a mere two years ago, so discovering she had a grandson was quite a shock. She's fond of calling Nini “Sonny Boy.”
