Lindy, the kind-spirited captain of the spaceship Asura, works for the Time-Space Administration Bureau. She enjoys drinking green tea with sugar (and sometimes cream) added, which is ironic given her appreciation of Japanese culture. She is Chrono's mother. 

3rd grader Takamachi Nanoha stumbled upon an injured talking ferret after hearing his telepathic cries for help. The ferret turned out to be Yuuno, an archeologist and mage from another world who had accidentally scattered the dangerous Jewel Seeds throughout Earth. Without the strength to collect the Jewel Seeds, Yuuno had resumed a ferret form and needed someone else to take on the task for him. He gave a red jewel to Nanoha explaining to her with this she could transform and use magic to combat the monsters that threatened them due to the Jewel Seeds. But the monsters are the least of their worries, as Yuuno and Nanoha are not the only ones out to collect the Jewel Seeds. 

After the events of the Lost Logia case, Nanoha waits patiently for the day she can reunite with her newfound friend, Fate. Although being an exceptionally powerful mage, Nanoha spends her days normally with her friends on Earth. But peace is once again suddenly shattered, as Nanoha is without warning attacked by a powerful mage. A group of violent mages have been attacking anything with magic power for their own goals. Nanoha and Fate, along with their friends Yuuno, Arf, Chrono and the Space/Time Administration Bureau must once more band together to stop these renegade mages from hurting anyone or anything else. Takes place after the first season of Lyrical Nanoha.
