"Life in Japan is like tofu," announces a friend over drinks at a late night eatery. "It's much too bland. What this country needs is a good dose of . . . evil."

A comment so sinister I almost choke on my chopsticks.

"I don't mean evil in the sense of crime and corruption. There's enough of that. I mean evil in the Machiavellian sense — that of intelligent darkness, planned malevolence, behind-the-doors heh-heh-hehing. What this country needs is a nice, juicy conspiracy theory."
