Akuma-kun (Movie)

As demonic forces begin stirring across the world, the aging Dr. Faust recognizes the signs of a catastrophe he can no longer fight himself. His search leads him to Shingo Yamada, a boy bearing the mark of the one destined to oppose the coming darkness.

Faust calls forth Mephisto II, a devil whose cooperation is far from enthusiastic, and binds him to Shingo's cause. Armed with occult knowledge and an unlikely demonic companion, Shingo steps into a hidden world of supernatural enemies that threaten humanity.
