Zombie-Loan and Shiki aesthetically have extremely similar lanky and 'edgy' art styles and ways of shading (very much hard colors and pure black shadows). Also, the stories are both about supernatural beings versus humankind, although both present the matter in much different ways. Both have dramatic moments and showcase the struggles of humans.
