Anime The manga series was adapted into an anime by

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 music was composed by
Kuniaki Haishima, including the opening theme "Grain".
David Sylvian was commissioned to write the first ending theme, "For the Love of Life", on which he collaborated with Haishima. 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." It was used for the first 32 episodes. The second ending theme, "Make It Home" by
Fujiko Hemming, was used for the remaining 42 episodes. It is the only song Hemming sung in her career. The credit sequence features illustrations from the book
Obluda, Která Nemá Své Jméno (The Monster Who Didn't Have A Name) by Emil Scherbe which was published by Shogakukan on 30 September 2008. An English dub of
Monster was produced by Salami Studios for
Viz Media, which had the North American license to the anime. The show aired on
Syfy's Ani-Mondays with two episodes back-to-back each Monday night at 11:00 pm EST, beginning 12 October 2009, as well as on its sister network
