@Crimson and Darkness

I do read correct.

1.- I know Kuroka winning Issei before BxB. I mean, Issei is not even midde class devil without BxB. But once he gets it, he doesnt have Ultimate Clase Level which Koneko said her sister had.

2.- I am saying even with the BxB, Kuroka being ultimate clase level should have defeated Issei with ease but Issei was superior.
