Nor as important as a character. Even when it's entirely plausible that Einhart could lose in this tournament, being a mian character as also the "superior" rival to Vivio, her defeat must be an event with big impact on the story because this will be a test for Vivio's growth as also to Einhart's character and pride. I simply don't see Corona being a suitable character to pull this on the plot, Sieglinde is the undefeated champion and is on the same group as Einhart and Corona so i totally can see her as the one handling Einhart her upcoming beating.
