Grandparents are still affected by the curse in the sense their memories are altered, but it can't actually kill them. Thus Keiko went insane due to her grandson's death, but the Numatas' deaths were not directly due to the curse, since there are more than two degrees separating them from Ikuo. The same would be true of the Mikamis except for their daughter teaching the class.
