Magical Girl Lyrical Nanoha-1
Magical Girl Lyrical Nanoha is set in a universe where magic is seen more from a technological point of view. Spells are referred to as techniques and mystical staves serve to enhance magic. The Space Time Bureau oversees the use of magic and protects people who may or may not encounter the supernatural. It operates a fleet of ships that move throughout space (not so much time) recruiting young people with magical talent and enforcing the restrictions on magic. The story mainly takes place in Tokyo, but in the latter part of the series it spans the entire planet as well as the Garden of Time and the ship Asura commanded by Lindi-san. Most of the story focuses on recovering or safeguarding mystical artifacts as well as the bonds of friendship and compassion.
This theme is currently set 6 years after StrikerS (7 in August 2014).
