The reason for such a dark prologue

Because of character development and I got plan for the future from this prologue. Eina and her dad actually played a really important role inside the story also the mysterious figure would be revealed some time inside the story.

FYI this prologue is kind of inspired by a naruto fanfic called Ryo the illusionist which I really liked. But sadly the update isn't stable. But this fanfic and a DxD fanfic called the change of a dragon (Fanfic.net) inspired me and make me like dark stories. Which kind of mess up. Dark stories make my heart races and hurt but it was exciting the feeling of adrenaline pumping through my blood and imagining what happen to character in such stories really test our mental capacity.
