You were test subject 408, and so Kou Hart would be testing things in you, but, he grew connected, and treated you like his own child

One day, another scientist rushed him into your room, and saw... you had turned into some kind of demon!!

He was told to kill you, and was handed a gun, but he froze, and turned to you, scared and worried

"W-what...? N-no no no... I can't kill my baby.. they are my angel!"
