Seina returns from his body enhancement to find Amane waiting to take him back to her house for some much needed training and rehabilitation. But Amane's not the only roommate at the house. Kiriko and Erma also move in to create an interesting living situation, to say the least. Seina somehow ends up on the wrong end of an extremely angry, knife-wielding, GP director, but things work themselves out, as things do, and he's able to begin his training to get comfortable in his new body.
