No offense but I consider that complete BS. Ishibumi suddenly saying that Issei needs to unlock Great Red's power and Ophis' power being unstable is the reason why he can't use DxD. When it was originally that the form is way too powerful and strains Issei too much which is understandable as it had him jump to Heavenly Dragon level. And let's not forgot how much stamina that form uses up. But Ishibumi just creates an excuse like that. I guess I can give it a pass because this is the final arc, but that's the most BS thing I've ever heard in DxD. I love Ishibumi and love DxD, but there are some parts that are complete BS in the story and the reason why Issei can't use DxD takes the cake. The ones that match up to that is the fake Phenex Tears and Yaegaki in Volume 18.
