Both prominently feature the psychological effects of superstitious beliefs on the human mind such that the affected people become unreasonable and ignore logic in favor of tempting rumors, and the story takes a turn for the truly dark. I would also suggest that for those familiar with Dusk Maiden of Amnesia who are checking out the Higurashi series for the first time, that you consider the remainder of the franchise. Kaku Outbreak is just one small part of a larger character study.
