I don't know how to write. Don't have any expectations. I know english though, so should be readable I guess.
Madara is a good villain and I believe his goal is suitable for a world like DxD.
No Harem or Romance, Fuck off horny lads.

He's strong for now but he'll have to get stronger. He has the rinnegan in both eyes, his overpowered EMS and Hashirama cells.
So yeah you can already guess how strong he he is.
