Her Blue Sky

Her Blue Sky (空の青さを知る人よ, 2019) is a Japanese animated film directed by Tatsuyuki Nagai — watch online on iFILM. A melodrama about guilt, music, and choices you can never take back.

Aoi grew up knowing her older sister Akane gave up Tokyo — and the boy she loved — just to raise her after their parents died. Now Aoi is about to graduate and the same pull toward the capital hits her. Then a stranger appears: Shinno, who looks and sounds exactly like Akane's long-gone ex-boyfriend, but frozen at twenty. He slipped through from thirteen years ago and cannot get back.

The film was produced by CloverWorks, with a script by Yoji Enokido. Director Nagai — known for Anohana and The Anthem of the Heart — returns to stories where time stops for grief that was never finished. Music is the thread connecting both timelines. Stream Her Blue Sky (2019) online on iFILM.
