I have the first volume, and to tell you the truth, even after reading the scanlations before, I don't find it toned down. Some differences here and there, but nothing that changes its maturity.
Maybe it's because I already consider the original OoT manga to be accessible to even the younger readers?
I might change my opinion when I receive the second one, though.
Don't be afraid to tell me I'm wrong, I won't be surprised if I am.
