Sengen Moichi

This Gate Keepers employee is an otaku who's absolutely crazy about pop idols. The first thing people tend to notice are his slim frame and glasses. He's currently attending the engineering college that's attached to the high school. He's particularly interested in subjects generally seen as fringe science or outright pseudoscience, and the university essentially considers him a heretic. His main task with Gate Keepers is developing the tools they use for their exorcisms.
