Like StrikerS Sound Stage X, the series' title does not contain "Magical Girl Lyrical Nanoha", indicating Nanoha Takamachi (and other characters from earlier series) makes only a few cameo appearances in it.
While training at Frontier Gym, Hallie asks Jill about her past history as a championship athlete. In addition to Jill's answer, Viktoria also explains her viewpoints and respect. The chat then moves onto Jill's work as a coach and the weak defense of Rinne, who then also arrives at the gym and admits such weakness.
