Assuming the class questions are the same for the Jap and English version, I'm sure there are plenty of questions the average Japanese teenager won't know. The relationship between Arsene Lupin and Sherlock Holmes, definition of a Femme Fatale, and the history of William Kidd. I'm assuming the English teacher's questions would be challenging for them too, but cake for us. The Kanji questions are bullshit, though. And the TV questions are based off Japanese law, I'm assuming.
I wouldn't bring up SJWs, either. There are threads for that, this isn't really one of them. Japan has never really given a fuck about progressive shit*, they're an extremely conservative nation, and it was a heavy critique of Japanese (and Asian in general, I guess) culture. The main themes of the game are politicians are mostly scumbags, and that if Japan's isolationist, hyper competitive lifestyle is to change, it has to start with the young. Thus, the Phantom Thieves and the ad nauseum repetition of "shitty adults." Each playable character in the game sorta represents the antithesis of an aspect of Japanese peoples. Take Makoto for example. She starts off as the perfect Japanese girl - (presumably) cute, intelligent, driven, diligent in her studies, content with following her sister's footsteps and dragging along in the rat race. Then you level up her Confidant a bit, in conjunction with completing the 6th Palace, and...
Ann is of mixed heritage, and is treated like SHIT by schoolmates and completely ronery even though she's literally hot enough to be a model because Japs are as racist as your average KKKodexer. Ann isn't lonely as part of a state of mind either, she has literally ONE friend in Shiho, and we all know what happens there. And so on and so forth for the rest of the cast.
*Latest Tekken is an example where the Kangaroo was removed to avoid the inevitable headache from animal rights activists, not because they actually gave a shit about punching kangaroos. Another example was the bitching following the shot of 2B's perfectly shaded turd cutter and subsequent fanart. What did Yoko Taro do? Asked for all the perverted fanart in a zip file sent to him. Why? Because he's a fucking bro and DGAF.
