She speaks formally in Japanese, definitely, but she doesn't talk like this.
I feel like wording the line somewhat unconventionally, like, "I refuse to obey you any longer!" or just "I will not obey you any longer" sounds more in line with her way of speaking, and sounds far less awkward and stilted than the rewrite.
On a completely different note, I can't help but feel Atlus USA are going a little over the top with the amount of promo material they're releasing for it. We're getting character trailers 5 months before the game releases, while in Japan they were only being released in the last month before release.
Obviously some of this stuff was slated before they knew they were delaying the game, but they've been releasing trailers left and right since then. I get that they want to maintain hype, but if they're trying to do that, they'll probably have to keep up the pace they've started here, and that'd mean by April they'd have probably shown the entire game off in trailers.
There's a fair bit of stuff Atlus JP clearly wanted to keep underwraps and didn't show in trailers, and it kinda worries me that those surprises will be ruined for western players if Atlus USA show them off. A few of the things shown in one of the recent trailers was certainly not what I would've expected to be shown.
