In the opening scene, a man in a pale blueish high school uniform is shown walking through gloomy woods. He abruptly falls to his knees, before screaming as though in pain. In his bloodied hand, he clutches a skeletal, woven doll. The episode formally begins with the Numata family gathered in their living room for an interview by a prospective home tutor. According to the strange man, who had tricked the older brother of the family into skipping his after-school supplemental classes to attend the meeting, the interview was necessary for him to assess whether his potential student truly needed his help. After a remarkable first conversation, in which the home tutor slaps his new student in front of the entire family, he introduces himself as Yoshimoto Koya. In his words, he would henceforth be in charge of Numata Shigeyuki - the younger, problematic son of an otherwise ideal family. So far, Yoshimoto is the 6th tutor to have attempted teaching Shigeyuki.
