Ah, I should really have explained to them. [He laughed somewhat putting a hand behind his head. It was at least something he could easily do.]

Akuma are machines or weapons created by the Millenium Earl by using the grief of someone who lost a loved one to recall their soul and trap it. This is what is used in an Akuma. [he is not going to explain what happens after that part because he thinks that would be a little too much.]

But as I said they are weapons that are used to kill humans and my goal is to stop them while freeing the souls that are trapped and are crying out for help.
