21st Century Girl is an omnibus feature that is of the girls, by the girls and for the girls. The work of 15 women directors under the age of 30, each of whom contributed an 8-minute film, the package highlights a range of genres, visions and thematic concerns.

High school track star Michiru and too-serious track captain Nitta grow closer as they search for meaning amidst the pressures of their lives. Two girls on the track team. They couldn't be more different as they deal with the problems of high school together.

The film consists of five films about Yamato in the post-COVID period. Tominaga's "The Fourth Eye" depicts a bewildered father who is introduced to his stepfather by his estranged daughter; Kiyohara's "The Light of March" tells the story of a woman who becomes pregnant at a young age and tries to flee the town. Takeuchi's "Makie no Bouken" (Makie's Adventure), Yamamoto's "Ano Hi, Kono Hi, Sono Hi" (Ano Hi, Kono Hi, Sono Hi), about a city employee who goes around taking video letters for people who are retiring, and Miyazaki's "Eri-chan to Kumi-chan no Long, Mundane Day" (Eri-chan to Kumi-chan no Long, Mundane Day), about two people who have too much time on their hands to bury a time capsule in a forest on the outskirts of town.

A short film by Risa Takeuchi.

September 20th. Sunny. I wonder if it bugs me so much because I can't see it. I've gotten totally obsessed with finding out what's inside that bump. It's all I think about on my way to school, in the bathtub, and when I'm trying to fall asleep at night. I mean, if I could just figure out what's inside that bump, I'm sure I could figure out lots of other things too.
