After last volume's surprising betrayal and bloodbath, Amamiya-the multiple personality detective of the Isono Criminal Research Lab-faces new threats from the young "Lucy 7" deviants! In the midst of new murderous messes, bumbling Detective Sasayama finds himself in a criminal profiler contest fueled by the Japanese media. An American profiler arrives to work on a decade-old serial killer case at an elementary school, but the real group that he represents and his ultimate goals are as mysterious as MPD-Psycho's huge "barcode puzzle." The Gakuso Society pulls some strings, the American begins to hunt down children, and this volume of MPD-Psycho promises to be the most titillating and confusing yet--but you'll love the ride! Jump on, as more players enter the fray and more inventive atrocities abound.
