Magical Girl Lyrical Nanoha

Magical Girl Lyrical Nanoha (魔法少女リリカルなのは) is a thirteen-episode anime that aired between October 1, 2004 and December 24, 2004, and is the first series in the main Nanoha continuity.

The series is a spin-off of the Triangle Heart series of games and OVAs. Nanoha, the magical girl and younger sister of Kyōya and Miyuki, takes precedence here while her sword-wielding siblings are reduced to minor characters. The late Shirō Fuwa was always named Takamachi and survived his originally fatal injury, new characters such as Fate Testarossa are added, and others, such as Fiasse Crystela, are removed.

A retelling of Magical Girl Lyrical Nanoha has been announced for Winter 2009 entitled Magical Girl Lyrical Nanoha The MOVIE 1st. It has been stressed that the movie will not necessarily overwrite the series as canon, but will tell a new parallel history.

Story
Nanoha Takamachi, a girl in 3rd grade at an elementary school, lives with her parents, who run a coffee shop, and her older sister and brother, who attend high school and university, respectively. Nanoha's regular life changes when she hears a voice calling to her on the way home and ends up rescuing an injured ferret. This ferret turns out to be a transformed boy called Yuuno, an archaeologist from a distant world, who enlists her aid to seal twenty one powerful artifacts called the Jewel Seeds. They come from his homeworld and have the power to grant wishes but are incredibly destructive when misused. To do this, Nanoha receives a crystal called Raising Heart that grants her magical powers.

As the story progresses, Nanoha learns more about her own powers as well as the other parties who hold an interest in taking the Jewel Seeds for their own.

The story is set in the first half of 0065, according to the Mid-Childan calendar.
