The mistress of an academy should be unbiased. She should support the excellent work of all her students, whether they are winged or wingless. In a perfect world, she would. The Valkyrie Academy is not a perfect place.

Kara and her two wingless friends, Hildr and Eir, are at the receiving end of Mistress Sigrun's "just" justice. They must partake in a fight without rules and no guarantee of finishing alive.

Only the future will reveal if the mistress will keep the fight fair.
