Irina officially became a part of his Harem since Volume 6 she was always in love with Issei from the start the biggest hurdle in her relationship is the no sex problem with Angels because she wants to stay a Angel but would risk this for Issei but Michael fixed this problem for her.

Michael created a Dimension outside of the Heaven System sort of a special room in which anything is allowed because you can be as lewd or deviant as you want in that Room of course he did it for the sake of Irina but also for selfish reasons the children would be very powerful, and would increase the power of the Armies of Heaven so he was also looking out for the interests of Heaven as well.

The Room that was created for her allows for Irina to never fall into a Fallen Angel status as long as she does her business in this Room.
