Maybe like EX, the dxd ZERO events will be important for dxd current story and we will see him in certain moment of this story.

But I am not sure about trust in someone who worked for the Old maous.. Maybe he is waiting his chance to make something bad..

As old Lucifer servant he can think that if Vali turns even more strong in this tournament he can serve him and plan dominate the world.. 

I think that this character maybe will be Hades last chance in the final volumes after lose big part of his army and allies..
