Dragon God Descends

He is the 'Satan' that makes the underworld tremble, but he calls himself the 'Dragon God'. Retired at eighteen, he hides in the philosophy department of a magic city, seeking revenge against his master. Invincible under the mask, he must deal with engagements, studies, and gang entanglements. When darkness surges on campus, he removes his disguise—this time, he protects not the battlefield, but the lights of thousands of homes behind him.
