As for Charlotte characters, my reasoning for Kazuki from Charlotte being discussed is because Kazuki was the only person introduced in the series to have been dissected, resulting in what happens to ability users. I think the “what if” scenario for people is a important thing to show
But of course, if you feel like those other middle school children topics should be changed, then I can just edit them and change them to a Rewrite character topics, since there’s others from Rewrite.
