So Rose is officially part of Issei's peerage. Normally I would have been fine but, this is ridiculous. Half the ORC is Issei's peerage! I know he wants a harem but he could at least get other servants on his own. The only new person is his queen and Bona might be a possible one, with Elmenhide along the way.

I dont have a problem with Asia, Xenovia, and Ravel to join, there were moments along the story were it was stated that they were going to be with Ise. Irina felt a bit kinda forced but I can work with that, but when did Rose did? I know it was Rias suggestion but come on.
