The uncensored, uncut manga event of the decade continues on its relentlessly bloody path, as MPD-Psycho Volume 7 shows that there's danger for our colorful cast on land, at sea, and in the air. Our conflicted "multiple personality detective," Kazuhiko Amamiya, controlled by his murderous Shinji Nishizono personality, finds himself on a hijacked airplane, along with innocent Miwa and her schoolmates. Meanwhile, their hunt for the missing Amamiya leads Machi and bumbling police detective Sasayama to an ocean liner commandeered by several new, bizarre characters-key figures in both the twisted barcoded-eye conspiracy and the deadly Gakuso Society!.
