Mahou Shoujo Lyrical Nanoha ViVid EP2 - Einhart Stratos

After questioning her about Vivio and Ixpellia, Ingvalt battles against Nove, determined to prove her own strength. Despite winning the match, Ingvalt, who, like Vivio, is a child using an adult form to battle, passes out from exhaustion. Recovered by Nove's sister Subaru and her partner Teana Lanster, Ingvalt, who is revealed to be a middle school student named Einhart Stratos, is examined by doctors, who reveal she possesses memories of the Sankt Kaiser Claus G.S. Ingvalt and has inherited his Belkan fighting style. As Nove learns more about Einhart and her ancestor's past, Vivio and her friends brush on the history of Sankt Kaiser in preparation for a meeting with Einhart.
