A sequel to the anime series titled Magical Girl Lyrical Nanoha A's produced by Seven Arcs premiered in Japan in October 2005, broadcast on Chiba TV.

Nanoha's regular daily life ends when she rescues an injured ferret who reveals himself as a young shapeshifting mage named Yūno Scrya.

An archaeologist from a parallel universe called Midchilda, Yūno came to Earth to collect a set of 21 dangerous ancient artifacts named the "Jewel Seeds" (ジュエルシード, Jueru Shīdo) that he first discovered in his own world.

In the series, Precia uses Fate to collect Jewel Seeds to reach Al Hazard, a mythical world where Alicia could be truly brought back to life.

Nanoha and Fate repeatedly face off over each new Jewel Seed they find, and the TSAB soon interferes to prevent the collateral damage caused by their battles.

Although they minimize the destructive side-effects of using the Jewel Seeds, they fail to prevent Precia from finishing the spell, and her final whereabouts remains unknown.

The first, Magical Girl Lyrical Nanoha Sound Stage 01, appeared on November 26, 2004, and contained 16 tracks; its story takes place between episodes two and three of the anime television series.

[20] King Records released the final CD, Sound Stage 03, on April 6, 2005; it has 16 tracks, and its story takes place after the conclusion of the anime series.

[23] Aniplex displayed a trailer of the film as well as character-design sketches and original drawings at its booth at Tokyo International Anime Fair 2009.

[27] A second manga, ORIGINAL CHRONICLE Magical Girl Lyrical Nanoha The 1st, illustrated by Yukari Higa, was serialized in Kadokawa Shoten's Nyantype from 2013 to 2016, and was compiled in seven volumes.

English-language fans wondering as to what would occur to the distribution status of the series that Geneon had licensed - including Magical Girl Lyrical Nanoha.

A fan pointed out that the English-language dubbed DVD boxset did not contain the credits for the director, automated dialogue replacement script adapter, and some voice actors.

[1] Davey C. Jones of Active Anime praised the series for building up to "intense double climax" with the revelation of Fate's backstory and the final battle on Precia's ship.

[35] Kimlinger noted the use of multiple animation directors who gave "each episode a distinct look" and allowed the series to "retain a level of stylistic continuity" that he described as resulting in an "uneven, but ... undeniably appealing" look.

[34] Although Tim Jones praised the character designs as "distinct enough to distinguish [between] the fairly large cast", he criticized the animation quality as ranging from "okay to downright lazy".

[36] Mania Entertainment's G. B. Smith criticized the English-language dubbed release by Geneon for having several inconsistencies in the performances, pronunciation of names and localization, but accredited these faults to the direction.
