Two leaders involved with the construction of an amusement park have been found crushed to death by large mannequins. Akechi figures out that the deaths were caused by flimsy metal gears; those gears were ordered by Chiyoko, one of the park's engineers, to avenge her friend's death as a result of brutal working conditions. After returning to Akechi's home, Akechi tells Kobayashi and Hashiba that he is determined to capture all of the Twenty Faces because his close friend Namikoshi started the phenomenon.
