Akuma-Kun

The age of the demons has begun. Dr Faust has foreseen this rise of evil. Unfortunately, he is near death and is unable to personally battle this upcoming threat. Faust entrusts a young boy, Shingo Yamada, to take the responsibility of ridding the Earth of this new evil presence. Faust finds a birthmark on Shingo's forehead that signifies that he is the chosen demon fighter. Faust summons from hell what may be humanity's only hope of surviving: a less than enthusiastic devil named Mephisto rises. After signing a pact in blood to save humankind, Shingo and Mephisto set out to battle the supernatural world.

Akuma-kun and his friends go to the Makai Amusement Park to solve the child kidnapping case caused by an autonomous mysterious toy. An original work for the theater of the Toei Manga Festival, which is an animation of the original manga by Shigeru Mizuki.
