Volumes 1-18 and that's not enough to complete one whole school year. So there will still more to come.

Maybe Koneko's growth rate would increase since she was able to use "Shirone Mode" ~that's just my imagination.

Anyway, I don't see Koneko really growing up to look like what she looks in Shirone Mode in the near future since she is Issei's loli. Maybe Ravel too, but with her figure, she doesn't count as loli in my books.
