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.

Gallery Fake

On a wharf on Tokyo Bay is a small gallery named Gallery Fake. The owner of the gallery, Fujita Reiji (藤田 玲司) , was once a curator at the Metropolitan Museum of Art in New York. He was a learned curator with remarkable memory, keen aesthetic sense, great skill in restoration of paintings, and knowledge of many languages, so he was called "the Professor." However, because of trouble in the workplace, Fujita was forced to quit the museum. Now he is an art dealer who sells paintings, authentic and fake alike, at extraordinary prices. His motto is, "One without aesthetic sense can't help being cheated out of his money. And, by being deceived, one may learn to distinguish the real one from the counterfeit." However, Fujita is not a villain. He truly appreciates art and the artists who spent their lives to create it. He is not someone who just earns money by selling fake paintings. Sometimes he takes paintings from a wicked politician who considers art only as a means of exchanging bribes. Sometimes he tries to restore destroyed paintings. Readers get to like him for his passion and true love for art. He often touches the lives of those he encounters, and people are attracted to him in spite of himself. --- - **Won the Shogakukan Manga Award in 1996**
