Guru Gourmet!

At 10:00pm, after the first round of drinking is over and the streets become deserted, the “conspirators” appear. The salaryman Tsuzumi, who is ordinarily a man of discipline, meets... an enigmatic woman known as Kuroda, who tempts him with fine wine, fine food, and a mysterious beauty. It is an unhealthy way of life, a second late-night feast after entertaining. Won't you be a co-conspirator and come eat with us, because after all, guilt is the best seasoning?
