(The Shadow Girl)

Here is the translation of your story synopsis:
Edward is a twenty-year-old scientist who has been hunting an untraceable criminal ever since he saw his parents drenched in blood. Then he meets Hanna, a girl whose face belies her age.
Her wound healed in a single night. And her shadow... obeys her.
Her story is suspicious.
Now Edward is helping her, but what are her true motives?
A terrifying scarecrow,
A massive shadow,
And a lost wolf.
Where will the story lead, and what will the ending be?
The question isn't "Who is Hanna?"
The real question is: "Will Edward keep helping her, or will Hanna be the one to kill him?"
