P DxD uses the powers of Ophis (practically the infinite). He needs Ryuutaimaru's help just for the moment, the fact that enemies in the ExE world will arrive faster than Ryuutaimaru was expected to take an incomplete form of GR powers to help Issei get used to GR's powers. following Ryuutaimaru is Issei's servant and I share the same soul channel, so from the fact that Issei is the representation of the Infinite and the dream, Ryuutaimaru feeds with Issei's aura. The form that Ryuutaimaru took is incomplete and is not the true power of GR that Issei holds. And infinity has been shown many times to increase the potential of a person to the limit, attacks based on infinity are more destructive than normal ones. And what about Infinity Blaster? does not use infinity? of course he does. PDxD uses infinity, but to a much lesser extent than DxD G.
