 After the house is burned by Karen Davis in "The Grudge", Kayako seems to be permanently clean; this is perhaps to signify her change of character, because in "Ju-on," she is somewhat weaker than she is in the remake.As in "Ju-on," she constantly crawls downstairs and rarely attacks people as viciously as she does in "The Grudge".In the American films, she seems to be a much stronger, more evil, and a more powerful Onryō because, as seen in "The Grudge 3," she can kill someone by ripping their eyes out and tearing off their jaw.
