Superpowered Case Files: Daybreak

His older brother, a criminal investigator, died in a car accident, leaving him heartbroken. But not long afterward, a mysterious letter made him realize that his brother's death had been no accident...

He said: For a while, I kept dreaming that my brother promised me he would come to my graduation, no matter how busy he was. Then he smiled at me so gently. I had dressed myself up carefully and waited, and waited, until it was late and the auditorium was about to close. But that tall figure never appeared. Then, in the next instant, I saw that warm face of his drenched in blood...

She said: You are the most heartless, cold-blooded person in the world, but you are also the most devoted and gentle. You save all your tenderness for the people you care about, yet you neglect yourself, and you neglect me. To me, even if the path ahead leads into an abyss, as long as you are there, I won't hesitate for a second.
