I don't think that the relationship of Rias is breakin up at all because she is the glue that holds everything together trust me without Rias you can't call Issei the Oppai Dragon no more, and his dreams of a Harem won't exist and his existence for all his dreams wouldn't be there no more because she holds everything together for him.

He is becoming less perverted but he will at the same level as a certain smut-novel writing Author of a certain manga his perversions can be toned down but what he has is incurable and it has been a source of his power for a while because I don't consider it insulting on his power based on luck or breast-power to win.

I am happy that he won't need this angle for his power ups but in terms of being not perverted that is impossible for Issei the disease of being a pervert that he has is incurable.
