Ichika is just to dense and shows no development. Issei in comparison was dense with little development until Vol.10 and then showed huge development as he started to recognise the girls' genuine feelings and reacted to them. Him still being the >>Red Virgin Emperor<< (thank you Draig) is a shame but makes scenes as in Vol.6 the "graduation information gathering" possible (each time I read that scene I think that Issei is unreachable for all of them since he is the one who will have the first times of the most school beauties).
