This volume was basically composed of two parts – the first part, with Tenma, his ex-fiancee, and Roberto, and the second part with Karl. Tenma continues to be doggedly good, saving two people who he knows could be dangerous to him. Seeing what Tenma's ex, Eva, had become, it was hard to imagine them ever being a couple – she was broke, her home had burned down, she drank all the time, and she even slept with Roberto.
The second part is odd. I have no idea what Johan's goal is, but I'm willing to continue and find out. It puts me on edge, knowing how much danger Karl, and his research partner Lotte, are in. I wouldn't be surprised if Johan either kills them or frames them for Edmund's death.
