Kowai Hito?

About half a year ago, a friend recommended Sayaka Murata's "Convenience Store Woman" and "Killing Reproduction," saying, "It's a kowai hito novel." I'll never forget the shock I felt then. I thought, 'Is that what kowai hito means…!?' But it's true that the creepiness and fear in those novels come from people... Personally, I like "Triple" and "Killing Reproduction."
