[1] It is the seventh installment of the Tomie film series, based on the manga series of the same name by Junji Ito, specifically The Gathering chapter from the third volume.
The process, however, was flawed, causing them to degrade and forcing them to attempt to locate more blood from a "pure" Tomie to sustain themselves.
Years later, a young man named Kazuki who recently witnessed Naoko, his girlfriend, being brutally murdered, is dealing with depression and PTSD, made worse by the fact that Naoko's body was never actually found.
In an attempt to repress his memories of the murder, Kazuki begins to work in a mannequin factory, where he attracts the amorous attention of one of the two girls-turned-Tomies who lurks behind the scenes at the factory.
Intrigued by him, Tomie persuades his coworkers to get them to introduce him to her, but when they meet, he realizes she looks exactly like the deceased Naoko, but due to his love for the original Naoko and his inability to move on from her, he does not feel any particular attraction to her.
