A series of murders shocks Tokyo’s Shinjuku ward, but Shigenori, a retired police detective, is instead obsessed with a gargoyle that seems to move. College freshman Kotaro launches a web-based investigation of the killer, and comes to find that answers may lie within an abandoned building in the center of Japan’s busiest neighborhood, and beyond the Gate of Sorrows.
