Magical Girl Lyrical Nanoha-4R
Magical Girl Lyrical Nanoha is set in a universe where magic is seen more from a technological point of view. Spells are mathematical and scientific creations, used by systems known as Devices to manipulate the world in the form of magic. The Time-Space Administration Bureau (TSAB) oversees the use of magic and protects people who may or may not encounter the supernatural. It operates a fleet of ships that move through dimensional space, recruiting young people with magical talent and enforcing the restrictions on magic.
The story surrounds the lives of some of the TSAB's most powerful mages, the dangerous events that drew them in, the compassion they showed to their enemies, and the moments which forged friendships that would last a lifetime.
The Nanona-4 theme differs from canon in only a very small matter, namely the seemingly dead daughter of a certain powerful mage antagonist is recovered and revived, allowing her to live her life with little impact on the events of the canon.
