In Re/Member, Asuka and her friends spend the majority of the film trying to find the body parts, and along the way, they find more information about the Red Person. Unfortunately for them, they look for everything but the most important part: the head. They find out that there are others who have gone through the same twisted game as they have and try to get some pointers on what to do next. Mr. Yashiro was someone who had played the game, and it is being played all over the world, so people won’t remember or have any recollection of what happens here.
The time loop is the main cause of their confusion. Many of her friends try to aim for the Red Person’s head and end up getting killed in the process. Shota is the one who gets eaten after attacking the creature with the rest of them. Like any good supernatural film, there is a chainsaw (conveniently) for them to use to take him down. In the process, Rumiko is pierced through the chest, and Atsushi is eaten.
Each member of the group had a way of attacking the Red Person, but it was ultimately Takahiro who chainsaws the creature’s head off. After doing that, the skull is on the ground, ready for Asuka to pick up and use. Right after doing that, Takahiro is killed by the Red Person as well. The one way to kill any spirit is by using a crucifix, which is what Asuka does. She replaces the head and breaks the cycle the next day.
