What I'm saying is that the water is still murkey. I'm not saying the it's wrong for Gasper and Valerie to betogether, just that the author as yet to make it clear as too what route that the seriea is going to follow. With the Sitri girls, he teassed earlier on in volume 14 that Tsubaki would eventually be with Yutto and that Gasper would be with the knight Tomoe, all I'm saying is that it is to early to see where it will all go.

Also, age appers not to be a issue with this series, as it seems that a generation of demons and Angels is about several hundred years in span. We have yet to get any proper time scale for life spans.

Also,the Valerie and Gasper situation is totally different. For Asia, she meets and falls in love with Issei at the start of the series and is only treated as a little sister until she starts developing. Also, Irina and Issei know where they stand; as they are childhood freinds they are closer but not too close. All I'm saying is that it could go anyway at this point.
