Futaro Gamagori was born into a destitute household. His father was a no-good womanizing lush; his mother, unable to afford medical care, died of illness. The young Futaro sets out on a life of serious crime — thieving, raping, murdering. He eventually becomes the rich president of a big company, but continues to debauch, assault and slaughter.

Fortunately, Gamagori is fictional — the main character in "Zenigeba," a manga story by George Akiyama. Zeni is a slightly low form of the word "money"; geba is from the German gewalt (power, force), and in this context means "violence." Hence "Zenigeba" could be translated as "Lust for Lucre."

The story began its serialized life in 1970 in Weekly Shonen Sunday published by Shogakukan. It was made into a movie that year starring iconoclastic dramatist/actor Juro Kara. Then, in 2009, the popular actor Kenichi Matsuyama played evil money-grubbing Gamagori in a television series.
