Yeah the French is correct, but not really natural correct, it looks more like someone who learned basic french phrases than anything. But hey at least the grammar is correct, contrary to most French in manga.
The only problem is the french phrases and you need to do google translate which is a pain. I wish the translation group put the translation at the side of the french speech to make things alot more easier.
@WingZeroHeeroYuy I won't do that as that'd modify completely the original manga. Best I can do is provide a translation in the comments or an extra page at the end of every chapter (Every chapter is divided in 3 parts).

Yeah, French is correct. The thing I'd say is, it's too polite.
But it's fairly good from the author to not make any grammatical mistakes for now.
