Sadayo Suzumura

鈴村 貞代, Sadako

She was a stalker of Masanobu. She died after being hit by a truck driver who fell asleep. Her nickname given by Gantz, "Sadako," is due to her bearing an extremely uncanny and creepy resemblance to the homicidal "ghost" Sadako in the Japanese "Ringu" horror novels and movies. (Source: Wikipedia)
