Akuma-kun  

Devil Boy, 悪魔くん

The emergence of demons has commenced. Dr Faust foresaw this rise in evil. Regrettably, he is now near death and unable to confront this impending threat personally. As a result, Faust entrusts a young boy named Shingo Yamada with the responsibility of eliminating this new malevolent presence on Earth. Through examination, Faust discovers that Shingo possesses a distinctive mark on his forehead which signifies that he is destined to be a demon fighter. In an attempt to safeguard humanity, Faust calls forth from Hell a reluctant devil known as Mephisto, who rises after signing a blood pact. Together, Shingo and Mephisto embark on a quest to combat the supernatural realm.
