The True Culprit

Emilia returns to her room, thoughts crashing into her mind one after another as she throws herself onto her bed and recalls everything she has experienced thus far. As Emilia goes over each event and the details that surround them, she begins to wonder if she has forgotten anything. She knows that Dietrich is the prince of the Northern Kingdom and that he's related to Hart. She also knows that Dietrich's father, Gregory, is obsessed with her blood. 

Suddenly Emilia bolts upright, a realization coming to the front of her mind. Any descendants of Hartavian would have demon blood running through their veins without necessarily knowing about it, having traits of a demon doesn't actually mean that Dietrich is the reincarnation. After killing Bethel, Hartavian took over the Southern Kingdom, so how could he be linked to the Northern Kingdom…Lastly, there is nothing that says the reincarnation will be born in the same generation as herself.
