M&M talked about how Ise is having trouble with his "alone" time, so they must know that the girls live with him. Same with Kiryuu since she and Asia are close friends. But outside the circle, I don't think so.

With Issei and Rias dating, just like I said in the previous post, the rumor is only Issei calling Rias with his name without honorifics. The rumors that have circulated in the academy is Issei "enslaving" the madonnas of the campus, so Issei dating the number 1 girl may not visited their minds yet for the sake of having their sanity intact. :D
