CrossEdge
I'm hoping the plot wont be similar to other dxd fanfic out there, where the mc suddenly found his heritage and easily accepted his so called parents, and create an alliance or opportunity for the devil faction and his multiverse friends. with the current strength of the mc he can easily destroy the devil faction alone so he doesn't need them.
Thanks for the chapter. I honestly want him to met them, and try to be a family. I don't think they will replace his adoptive parents or take their place, but he should still treat them as parents even if he wasn't raised by them. The father did what he thought was right for him, and his mother prolly nearly died protecting him.
