Yeah I mean like drowning people - I get that. The German folklore "Wassermann" does that as well (for fun, he keeps the souls of the drowned in jars inside his home). A water-spirit that drowns people and animals is in general present in most folklore all over the world to teach people about the dangers of water in a more mystical way or during times when physics were unknown to us. But rape? Like what the actual fudge? Only in Asian folklore will you find fucked up shit like that.
