This is a remix, not a rewatch. It strips away the fractured timeline that defined the first six films and rebuilds Shiki and Kokuto's story in chronological order, forcing you to see how their connection was always inevitable even when the movies scrambled when you learned it. New scenes fill the gaps between what you thought you understood and what was actually happening. By the time you reach the climax, you're not remembering the originals, you're experiencing the love story the whole saga was always telling, just hidden behind narrative architecture that demanded you piece it together yourself.
Kara no Kyoukai Remix: Gate of seventh heaven is an hour-long theatrical compilation that came out ahead of the seventh and final film. It gathers key themes and scenes from the first six movies and arranges them chronologically, starting with the second film and then moving through the fourth, third, first, fifth and sixth. Most of the footage is existing material, with some new scenes mixed in. At the heart of the story, Mikiya Kokutou meets Shiki Ryougi, a strange young woman in a kimono, in August 1995. When he learns they attend the same school, he tries to befriend her, and she slowly opens up, until he begins to see a deadly side to her.
