Biography: Mutsuo Toi was born, March 5, 1917 in Okayama, Japan. After his parents died of Tuberculosis, while he was still a baby, Toi and his sister were raised by his grandmother. He lived a seemingly normal childhood until the age of 17, around which time his sister married. This event, apparently triggered young Toi to become socially reclusive. In 1936, he began crawling into the beds of young women, in the middle of the night, seeking sexual intercourse. This was a traditional Japanese activity called 'night-crawling', or Yobai. In May of 1937, Toi was diagnosed with Tuberculosis and soon found his sexual advances being rejected by the young women in the village. In the deep night, on May 20, 1938, he exacted his revenge by cutting the power line to the entire village, beheading his grandmother and savagely killing 29 neighbors. At sunrise, Toi shot himself in the chest and died.
