Toei has uploaded a longer 3-minute supercut trailer of the anime films To Every You I’ve Loved Before and To Me, The One Who Loved You on its YouTube channel. Both films opened in Japanese theaters earlier this month on October 7, 2022.
As a courteous warning, the long trailer also has some spoiler scenes from both films featured in it.
To Every You I’ve Loved Before and To Me, The One Who Loved You are based on the 2016 novels of the same name written by Yomoji Otono and illustrated by shimano. The stories involve the concept of parallel worlds and can be read in either order to complement each other.
To Every You I’ve Loved Before is directed by Atsushi Matsumoto (Infini–T Force Movie: Gatchaman – Saraba Tomo yo, Night Raid 1931) and produced by BAKKEN RECORD, while To Me, The One Who Loved You is directed by Kenichi Kasai (Amanchu!, Nodame Cantabile) with TMS Entertainment as the animation production company. Both films have screenplays written by Riko Sakaguchi (Mary and The Witch’s Flower co-scriptwriter).
Seven Seas Entertainment releases both novels in English. It describes the synopsis of To Every You I’ve Loved Before as:
In a world where people regularly travel between slightly different parallel universes, Koyomi Takasaki lives with his mother after his parents’ recent divorce. Awkward and studious, he has trouble making friends at his new school, until his classmate Kazune Takigawa seeks him out. She claims that she’s moved here from another world where she and Takasaki are lovers… But could he be the one who’s actually from a parallel world?
Meanwhile, the publisher also describes To Me, The One Who Loved You as:
In Hidaka Koyomi’s world, travel between slightly different alternate universes is commonplace. After his parents’ recent divorce, Koyomi lives with his father, and falls in love with a girl named Shiori Sato when they meet at his father’s workplace. But their young love seems doomed when their parents get remarried–to each other. Is there some parallel world out there where Koyomi and Shiori can be together as lovers, not step-siblings…and what could be the price if they try to find out?
