Monster (anime) from Best Dark Anime
The manga series was adapted into an anime by Madhouse, which aired between 6 April 2004 and 27 September 2005 on Nippon TV. Directed by Masayuki Kojima and written by Tatsuhiko Urahata, it features original character designs by long-time Studio Ghibli animator Kitarō Kōsaka which were adapted for the anime by Shigeru Fujita. The anime includes an instrumental theme by the Chilean folk music group Quilapayún, "Transiente", which originally appeared on their 1984 album Tralalí Tralalá. David Sylvian was commissioned to write the ending theme, "For the Love of Life", on which he collaborated with Haishima Kuniaki. In the cover notes to the official soundtrack he said, "I was attracted to the Monster material by the moral dilemma faced by its central character. The calm surface of the music giving way to darker undercurrents, signifying the conscience of the lead protagonist and the themes of morality, fate, resignation, and free will."
