Instant Death [DxD]

Yo, I was investigating my brother's death that happened a month ago then I stumbled in this place. I was initially confused to what happened as the doctor said that he didn't get any physical injury or even organ failure. It's as if his death was a natural one that doesn't need any reason to be explained. I read the book he made and finally understood what happened. Who would have thought that a 'Human Being' would die in the hands of a fictional character? I just want to inform everyone that I am currently making a new book that uses the concept of Xander Ranvil's brother and its name is 'Journey to becoming a Mage God' ame right? I know, I know.. Please support it, Thank you!
