Manga Sagawa-san
In the song "Too Much Blood," Mick Jagger asks, "Do you remember the Japanese student that killed and ate his girlfriend in Paris?" That world-wide-known cannibal is Kazumasa Sagawa. After being released by French authorities for having a "mental disorder", he was sent to Japan -- but Japanese psychologists couldn't find anything wrong with his mental condition, so he was released scott-free.
In his own comic, written and drawn by himself, Sagawa details the murder and the banquet just like a gourmet reviewer.
