I can't even imagine how overpowered Miu's father is going to be. He didn't seem like such a bad guy because he cared for Miu but I think i probably know what happened. He was good and everything bu t the death of his wife (Miu's mother) changed him completely.
I like how the smiling steel fist's clothes burned off, but his comic was completely intact (survey included) when passed through the electric barrier.
