13화: 청소년들이 버려진 학교에서 백몽가타라이 카이단카이 게임을 하며 사라진 친구와 신비로운 목소리를 드러냅니다.

13

A group of teenagers sneaks into an abandoned school building to play a game of Hyakumonogatari Kaidankai: after lighting one hundred candles, the participants take turns telling ghost stories and extinguish one candle with each story told, expecting something extraordinary to happen after the last candle goes out. They tell ghost stories borrowed from previous Yamishibai episodes, putting out candles as they go. When one of the boys, Kouki, begins telling the 99th story, he confesses that he has played Hyakumonogatari Kaidankai before, but the 99th and 100th candles were accidentally put out at the same time and the boy who was supposed to tell the 100th story vanished. After another boy, Akito, asks what happened to the vanished boy, Kouki reveals he has just told the 99th story and invites the group to ask the vanished boy himself. He finishes his story by revealing he also heard a voice saying "See you after the next hundred" that night. The 99th candle is blown out by a mysterious figure who appears in the room, causing the group to panic. The kamishibaiya appears and says "This is the story of everyone who had a dreadful experience after a hundred stories were told..." before the 100th candle is blown out. (Source: Wikipedia)
