CERTAIN SCIENTIFIC RAILGUN GN VOL 17

Welcome to a world where mysticism and science collide, and supernatural powers are derived from either science or religion. At the heart of this world is Academy City, an advanced metropolis whose population is comprised mostly of students. Meet Mikoto Misaka, the third most powerful Level 5 esper in Academy City. Together with her best friend Kuroko Shirai and the other members of Judgment, a student-run law enforcement agency, Mikoto delves deep into the dark heart of the scientific sprawl she calls home, and uncovers secrets she wishes she hadn't!
