Suicide Club Collection

54 high school girls throw themselves in front of a subway train. This appears to be only the beginning of a string of suicides around the country. Does the new all-girl group Desert have anything to do with it? Detective Kuroda tries to find the answer, which isn't as simple as one could hope.
