All right, here's a summary of the E3 Arc, so far:

You and Eise are engulfed in an illusion of victory by Akira Kariya, but you can snap out of it in a few seconds. Catherine, meanwhile, is fighting Elizabeth Cortes (one of the MMO Makers), and Balthazar 'Thaz' Carlton, one of the Agents. Conor, meanwhile, is fighting Clarisse (NPC controlled by GreenGoat), and Joshua's reinforcing him. Ken Saddler (another MMO Maker) is also helping them.

Side plotlines are Amelia and Rose talking, then Amelia and Heinz Harper talking, in which the latter reveals that Ascot got raped while on a mission, but mindwiped his own memories of it to continue functioning. Then, after that was Heinz talking to the President (NPC controlled by Mass City) in which its revealed that they have feelings for each other.
