Ikoma getting beaten so easily was bullshit poor writing, nothing else. I hope the author will recover his touch in the next episode.
War criminal Mumei deserves anything bad that's going to happen to her. It would be cool if she was turned into another abomination like Horobi. She had plenty of time to realise what kind of a scumbag she's following, but she willingly chooses to ignore it. I don't care if she's 12; she has more life experience already than most 30 years olds even in that world.
