Sadako vs. Kayako is a new horror film that features the main horror characters from the movies The Grudge and The Ring. Sort of like when Hollywood gave us Alien vs. Predator, except this is from Japan. Anyway, the distributor gave the ghost character Kayako Saeki from The Grudge her own Instagram account to promote the new flick. See her in everyday activities with her sidekick Toshio in all their creepy glory.
