Fuck! I burst out laughing when she was the spy. I did not expect her lol. Of all the seedy looking people or people who looked weak-willed that would betray them, it was her. I wonder if there are more than just her though. I doubt she is the last one who will betray them.
At least the spy is interesting. This also got into the anime trope territory of "I KNEW WHAT YOU KNEW I WAS THINKING SO I PLANNED AHEAD... etc etc"
It's also somewhat disappointing that the Red Team boils down down 'we want a kingdom' which is pretty fucking retarded. I mean who even thinks like that? In the past sure. But modern era gangsters?
At least the other characters have decent motivations that I can understand and accept. But not those two. Unless it's a massive bait since they didn't actually say anything and Mion proposed it.
