Tenkawa Toichi is a normal, ordinary high school boy, except he has a secret identity - he is a member of the evil Phantom Organization, going by the alias Wolken. They are planning to conquer the Earth, but is being met with opposition from the so-called Angel of Judgement, Mighty Heart (Who, coincidentally, is a classmate of Toichi, Maishima Kokoro). Surprisingly, Mighty Heart is so weak that even Wolken's underlings can beat her easily, but they only figure out her ultimate weapon after Wolken accidentally comes into contact with her body...
