Magical Girl Lyrical Nanoha (魔法少女リリカルなのは Mahō Shōjo Ririkaru Nanoha) is a thirteen-episode anime that aired between October 1 and December 24, 2004, and is the first series in the main Nanoha continuity. A direct light novel adaptation of Magical Girl Lyrical Nanoha was published in 2005, shortly before the sequel series, Nanoha A's, went on air. Another retelling was released in Winter 2009 as a theatrical movie titled Magical Girl Lyrical Nanoha The MOVIE 1st. It has been stressed that the movie did not necessarily overwrite the series as canon, but told a new parallel history.
