Blood Code

In order to better shape my future,
I came to a strange city alone seeking to attain knowledge.
However, this happiness could not be shared with my father, whom I had recently learned died in an accident.
Helplessness and panic, It is my choice...
But the reality weighed heavy on my heart
Accidental deaths are rarely an accident...
Could someone, once a friend, perhaps be the murderer?
Who is the killer...
What should I do...
What is the purpose of the Holy See?
What secrets are held by the Bloodline?
In the end who is the real boss?
