Differences between Manga and Anime

 * Akiyama originally survived the prison break but in the anime, Akiyama was immediately shot by Genkaku's machine guns and then dies while protecting Ganta from an Undertaker.
 * Akiyama is then shown escaping on the ship in the anime, however, it seems that his role is filled by Endō.
