It might be she was annoying in DP, or just because she's smaller compared with the other girls. One example is PM Gals. Despite she was added together with the other girls, she didn't join the fun until a few doujins later. She wasn't their preference but they added her later prob because some fans wanted it and the whole thing was about Ash fuck em all.
