Yeah, 75 is the worst episode, not only for the obvious reason.
1) where's the dwarven veil for unmarried princess? She used to wear it frequently and correctly under different circumstances. It's understandable to see her not wearing it at all-girl school but It would be nice to see her put on the veil the moment she left the school. I believe the source on latest chapters are taken from the magazine and this mistake could be fixed in the book release. The author is a veteran after all.
2) trying to justified the school orgy arc by making the victims couple in this chapter. It was unjustifiable the moment he runs the orgy trope. Before the ringleader triggered the plan, the girls were drugged and raped systematically and now author brushes it off as a crowd frenzy/ memory lost. I don't think the parents are going to shrug it off as easy as in the current story.
I'm quite surprised the author didn't go with the imperial scandal right after the campus incident. The development would be more harmful to the crown than a random successful officer is actually an imposter WITHIN an immigrant tolerant empire. IIRC almost half the school got into orgies, I can't say the noble families within and without the empire are going to be very happy with the unwanted bastard children, especially the crown prince is somewhat shady in the incident. The crown prince is definitely not going to denounce his GF, that can be a serious trouble if such arc continue right after it.
Now that author wants the school to function so that he can involved the princesses on the bench for the arc. I thought the school would be a gloomy and empty but the chapter proved me wrong, it was a bad decision imo. If the dwarven princess returned to somewhat devastated school, I'd say she would be more motivated to help MC and now she's just plain stupid (can't blame her though, nobody could expect the senator's secret chamber).
3) The senator is definitely under german payroll or is the secret admirer of the mega-secret-edgy-destroy-the-world-because-the-world-wronged-me bad guy from the future behind the Imperial german.
Hell damn, every problem within Britain is somehow caused by highly positioned sleeper agents from german within the British government and I expect this trend to continue, which is not good. I would bet at least half of the successors for British crown were already the victims of german spy and the other half are on their waiting list. At least we haven't had the chance to see one desperate royalty handed the empire to the german in return for the crown under foreign occupation, which Im expecting to be happen soon.
The strategy is definitely good and fit for the story but the british crown have to be damn stupid to be the sitting duck for every occasion. Well the queen is a smart one with her limited screen time, Luca as well, but only when they patronize MC. Apparently they haven't been working hard to root out the potential harm within the empire and the government after the school nurse incident. Not even trying.
