Yeah, there is that. Though honestly a good amount of that wall of text once you see the politics could be ignored and you wouldn't really be missing out on a lot. I'm a fast reader so I just skim through it quickly when it hits politics I don't care too much about.
That said, what I like about the later parts of the manga is that they move on to show how the organisation is changing and evolving along with most of the characters. Treilla had a really nice feel good moment at the end of the Pinochio arc, at first I didn't like the arc because it takes a while to really kick in, but towards the end it shows how even Treilla, seemingly the most stable of all the girls is herself obsessed with being the best possible weapon for her master.
So far there hasn't been anything I haven't loved about Petrushka and it's a nice shift in direction from combat lolis with little subtlety to a man teaching his jail bait cyborg how to spy.
The manga his high and low points, but it's been alright. Glad someone got around to translating all the later volumes because the middle volumes after the anime ends are a bit slow for a while, but the later ones paid off.
