From Tokyopop:
Sato Tatsuhiro is a drug-addled "hikikomori" (a Japanese shut-in) who thinks a sinister organization, NHK (Nihon Hikikomori Kyoukai), is the cause of all his problems! He falls in love with a girl, Misaki, who he thinks is trying to assassinate him, but doesn't know how to talk to her or if he can trust her. The more he stays in his house watching anime porn, reading manga, and doing drugs, the harder it is for him to leave. Only Misaki can keep him from rotting away in his own apartment!

Michio Yuki has it all: looks, intelligence, a pedigree as the scion of a famous Kabuki family, a promising career at a major bank, legions of female admirers. But underneath the sheen of perfection lurks a secret with the power to shake the world to its foundations.

During a boyhood excursion to one of the southern archipelagos near Okinawa, Yuki barely survived exposure to a poison gas stored at a foreign military facility. The leakage annihilated all of the island’s inhabitants but was promptly covered up by the authorities, leaving Yuki as an unacknowledged witness—one whose sense of right and wrong, however, the potent nerve agent managed to obliterate.

Now, fifteen years later, Yuki is a social climber of Balzacian proportions, infiltrating the worlds of finance and politics by day while brutally murdering children and women by night—perversely using his Kabuki-honed skills as a female impersonator to pass himself off as the women he’s killed. His drive, however, will not be satiated with a promotion here and a rape there. Michio Yuki has a far more ominous objective: obtaining MW, the ultimate weapon that spared his life but robbed him of all conscience.

There are only two men with any hope of stopping him: one, a brilliant public prosecutor who struggles to build a case against the psychopath; the other, a tormented Catholic priest, Iwao Garai, who shares Yuki’ls past—and frequently his bed.
