Set four years after StrikerS, the Sixth Mobile Division has disbanded and Nanoha Takamachi has taken a leave of absence to raise her adoptive daughter, Vivio Takamachi. After reaching the fourth grade of her primary school, she is finally given her own device, which gives her the form of the Sankt Kaiser mode. She later meets a girl named Einhart Stratos who, like Vivio, is a descendent of a ruler of the Sankt Kaiser era, and wishes to prove her fighting style the strongest.
- Vivio Takamachi (高町 ヴィヴィオ Takamachi Vivio?)
- The protagonist of this story, Vivio is a girl who was rescued and adopted by Nanoha during the events of StrikerS. Her intelligent device, Sacred Heart, is shaped like a crystal and appears to be a rabbit, which is nicknamed Cris (クリス Kurisu?). She is able to transform into an adult form at will, which she claims is more convenient for battle skills. It is similar to the Sankt Kaiser form she fought Nanoha in beforehand, except that her barrier jacket is white instead of black.
- Einhart Stratos (アインハート・ストゥラトス Ainhaato Suturattosu?)
- A user of Kaiser Arts that had given herself the name of the previous Sankt Kaiser, Heidi E. S. Ingvalt (ハイデイ・E・S・イングヴアルト Haidei E S Inguvaruto?). She picked street fights in order to prove that Hegemon's strength is the greatest of all Belkan warriors. Like Vivio, she has heterochromia and possesses both a child form and an adult form, though the latter is taxing on her mind. Her true identity is discovered by Nove and the Nakajimas, who decide to help her better understand everyone and become acquainted with Vivio, the two girls eventually becoming friends.
