Fanfic Fuel: The exploits of the LDF and the MBC pre and post-Hino Nightmare.
What the situation is like in other countries that condemn the use of the MBA.
Genius Bonus: What do you get if you convert 505 Kelvin (written "505K") to the Fahrenheit scale? 451 degrees Fahrenheit, which is the real title of the book they're referring to as 505K. note 451 degrees F is actually closer to 506 degrees K (about 505.93 degrees K), but close enough .
Harsher in Hindsight: The mind blowing attempts at censorship in the franchise will hit hard once you learn that China and Russia are enacting new laws/rules about censoring media that are harmful to its leaders or to how things are in those countries in recent years.
Signature Scene: Kasahara is saved by Dojo when MBC officers raid a bookstore in Ibaraki.
Values Resonance: The idea of a country like Japan doing censorship resonates in places where censorship is heavily opposed despite having popular strongmen in power.
Captain Obvious Reveal: You'll already know Kasahara's "Prince" is Dojou long before it's finally confirmed, especially since the voice and hairstyle are a perfect match to the silhouetted figure in her flashback. Plus, she always wonders why "her heart flutters" only when he compliments her.
