Here i'll even quote it to you from the author himself.

"“Who would be among the top 10 strongest in the world that Vali was speaking about in volume 4?”

It was even written in the message that the fans are also debating about this. …..Seems like everyone are interested in it. I do have the setting of it just in case, so I will announce it here. Of course it is a DxD original ranking.

In no particular order Ophis, Shiva, Vishnu, Brahma, Śakra, Thor, Typhon (Or Fenrir), Hades, Aten, and Lugh.

By the way the true Sirzechs and the serious Ajuka will be placed among the ranks."
