Do you believe souls exist? Could they exist in a form that science can explain? If you happened upon evidence that souls exist, would you believe it? Would you abandon some of your principles in pursuit of the truth? If the truth demanded human lives, would you be willing to sacrifice yourself?
Five years pass. The deeper he gets in his pursuit of the truth, the more determined he becomes. He would give his life for the truth without regret. But in its name, he also reaches out to those poor, unfortunate people.
An accidental investigation reveals hidden crimes. The deeper the investigation goes, the clearer it becomes that the truth is not hard to find. Open that door, and every secret within is laid bare.
Past and present intertwine, while reason and madness hang on a single thought.
