So almost 3 months after it was first announced, Samael (SSR kamihime) has been added to the gacha yesterday. Back then, I think Aidoru asked if Kitamura Eri voiced her R scenes as well. According to Samael's entry on the wiki, no, Kitamura Eri does not voice her in the R version. She voices her in the all ages version, while they got someone else for the R version.

Oh, and the maintenance yesterday also added 5th floors/levels to the accessory quests. Does that mean that this old-strongest-content-yet becomes the new-strongest-content-yet?
