I've never heard of Nim being a sister to D. Maybe to Python, but not D.
Nim's home page acknowledges borrowing from Python, Ada, and Modula, as well as C/C++. I don't think D is part of the mix.

While Nim indeed comes from Wirthian heritage instead of K&R heritage, its goals are pretty similar to D. You could say that Nim is for (Object)Pascal what D is for C(++). I think that's what the GP alluded to - not that Nim borrows directly from D or the other way around.
