It is interesting, but overly girly and limited to female avis.
As for it's theme angelic... I wonder if they will make a demon version for male avis... this favoritism for female avis is getting a tad old.
The story hints that the female's character may get some poses--or, possibly, another male character may come into the story as the manager is trying to apparently protect her from unsavory people. I wouldn't get your hopes up for a lot of manliness but there may end up being a least some male poses involved. Hopefully.
I agree that REIs tend to have a very strong feminine slant. I'd like a few more boy oriented ones as well. But, as ever, I'm not dismissing this one yet since the story indicates some male characters may appear. C=
