Every week at 5 p.m. an old man in a yellow mask (the kamishibaiya or kamishibai narrator) shows up at a children’s playground and tells them ghost stories based on myths and urban legends of Japanese origin. The man tells the stories on the back of his bicycle using a traditional kamishibai (紙芝居, Paper Drama) method and features a new tale each week. In the third season, instead of the old man in a yellow mask and his kamishibai stage, a boy (later revealed to be the kamishibaiya in the form of a child) sits on a playground slide and sings, “Friends on that side, come to this side… Friends on this side, go to that side…” as he draws illustrations of the creatures in the stories. At the end of each episode, the narrator’s mask sings the closing song to him, multiplying in number as each episode ends with the final one being worn on the boy’s face. As of Season 4, the kamishibaiya returns, telling the stories to children at a playground every 5 p.m., going back to the original format of Seasons 1 and 2 (voice actors are different every episode). In Season 5, the children are not seen playing on the swings. Instead, they gather to the call of the old man in silhouette. In Season 6, the old man tells his stories in a forest instead of a school. A shadow takes the form of the old man then puts on the mask as he introduces the story. In Season 7, the old man tells his stories in a creepy apartment. In Season 8, he tells his stories at a busy urban intersection, surrounded by vague shadowy passersby.
