Akuma-kun: Youkoso Akuma Land e!!

Children begin disappearing after discarded toys come to life under the influence of a mysterious Western doll. Hypnotized victims are carried by train into Devil Land, a strange amusement park existing in another dimension, where the apparently playful attractions hide a far more sinister purpose.

Akuma-kun, Mephisto II, Hyakume, and the Twelve Apostles follow them into the park and discover the Black Devil behind the abductions. The creature intends to drain the children's life force and use it for its own resurrection and a darker plan for the human world. To bring the children home, Akuma-kun must break the spell and turn Devil Land's supernatural tricks against their creator.
