Synopsis

Four years after StrikerS, Nanoha and her adopted daughter Vivio are living peacefully together. Vivio, who's the reincarnation of the ancient Sankt Kaiser Olivie Segbrecht, gets her own device called Sacred Heart when she starts fourth grade, unlocking the ability to transform into her adult Sankt Kaiser form. Things get interesting when she meets Einhart Stratos, another girl descended from a Sankt Kaiser—specifically Claus G.S. Ingvalt. Einhart's obsessed with proving her fighting style is unbeatable, but Vivio manages to befriend her. Together with their crew, the two enter a martial arts tournament where they face off against all kinds of opponents and gradually uncover secrets about their own legendary past lives. The second volume also includes a crossover one-shot with Fate/stay night.
