*10 years ago*
???: *Sits in a big chair*
*Someone comes in*
???: Oh...it's you
Katashi: It's been a while old friend!
???: Indeed...it has
Katashi: Well I just got back from another murder I committed
???: Who did you kill?
Katashi: An interesting couple. A demon and an angel. Their names are Vayne and Lucy. Vayne is the son of the former king of Hell. Lucy is the daughter of the former general of Heaven, her brother just so happens to be the Grim reaper himself.
???: I see...
Katashi: But that's not all. It seems like those two had kids. Three kids. One is human, the other is literally a panda. I suppose those two kids are adopted. But the third child is who I found interesting
???: How so?
Katashi: Unlike the other two. This child was given birth from them. Making him their biological son. Which means....
???: He's a nephilim. The first one to be born since the nephilim race went extinct thousands of years ago.
Katashi: Seems like the couple didn't care that they were supposed to be enemies. They always loved each other til the end. And now those three kids are orphans now. Heh...how amazing
???: you really are insane
Katashi: Well yeah, no shit!
???: Yes indeed. This nephilim child is interesting. Do you know his name?
Katashi: Nope. Didn't bother to ask. What are you planning to do?
???: I don't know why but this boy could possibly be a threat to the order in the future. Something tells me he's a special case. I will make sure that doesn't happen
Katashi: Great. You do that. I'm gonna go commit more murders *leaves*
???:.......
