A mercurial 21-year-old Kana (Yuumi Kawai), is a hair-removal technician at a salon in Tokyo, who bristles against the beauty expectations placed on women her age. Her erratic mood and default to self-destruct impacts all of her relationships, as moments of levity erupt into violence and optimism simmers to despair. At 27, Yamanaka became the youngest female director to win the FIPRESCI award at Cannes and was nominated for Best New Director at the 2025 Asian Film Awards. No one over 20 was allowed on set while making the film.
