I was confused too. You have to get to the colliseum with Karl first, wait for your and Seria's squad and beat Post-Graham (why the heck is he called "post" anyway? full power o serius seem more fitting...)

Then, once you do so, you have to do it again. On his way to the colliseum, Karl will have a new scene. Once you beat "Post" Graham again, the following cutscene will have some minor changes and you'll get to fight him with Karl's squad ALONE.

He's not that difficult, but can be pretty annoying. I managed to beat him when only Karl was left standing, with 1 Hp (god bless angel idol). You seem to have beaten him in his "Post" form once, so just do the Post Graham requirements once again and you will get to fight him in his Awakened form
