The second girl is even more shocked when Haruomi's eyes begin to glow after he has another fit, this time in the form of a massive headache.

She is then ordered by her boss to kill Haruomi, but he is rescued by a demon (also referred to as a "branch" (枝, Eda)) named Zilch (ヂルチ, Djiruchi).

Haruomi soon finds himself caught in the middle of a war between demons and a religious order called the "Seventh Gospel Organization" (第七福音機関, Dai Nana Fukuin Kikan).
