PewDiePie did a Let's Play of Misao that consisted of 8 episodes, which started on February 18, 2013 and ended on March 1st, 2013.
Pewdelia is a student at a school where her female classmate, Misao, mysteriously disappeared three months ago, and is believed to be dead. She begins to hear Misao's voice calling for her help. Pewdelia's classmates blame a string of supernatural events on what they call "Misao's curse." After an earthquake shakes the school and all students as well as Pewdelia's homeroom teacher—Mr. Sohta—are forced into another dimension haunted by monsters and ghosts, Pewdelia must solve the mystery behind Misao's disappearance.
Through the game, Pewdelia has to gather several body parts of Misao in order to place them in the altar outside of the school. Also, in the game, she must kill 4 people in order for Misao's soul to rest in peace, if she kills Toma, she will get the "bad ending", if she kills Mr. Sohta, she will get the "good ending".
