MW

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’s past—and frequently his bed.

Regardless of the title, this volume does not include "Tomie Again" within its pages. Note 3: Some people also consider "Tomie no kyoufu gaka" [ シリーズ富江の 恐怖 画家] as part of the Tomie franchise.

No Longer Human (ITO Junji)

Macabre manga master Junji Ito applys his singularly anxious touch to a manga adaptation based on No Longer Human (Ningen Shikkaku in the original Japanese), a classic of modern Japanese literature written by Osamu Dazai. The poignant and fascinating story of a young man who is caught between the breakup of the traditions of a northern Japanese aristocratic family and the impact of Western ideas. Portraying himself as a failure, the protagonist of Osamu Dazai's No Longer Human narrates a seemingly normal life even while he feels himself incapable of understanding human beings. Oba Yozo's attempts to reconcile himself to the world around him begin in early childhood, continue through high school, where he becomes a "clown" to mask his alienation, and eventually lead to a failed suicide attempt as an adult. Without sentimentality, he records the casual cruelties of life and its fleeting moments of human connection and tenderness.
