Known for acclaimed TV anime like The Tatami Galaxy and PingPong, Yuasa Masaaki adapts Tatami Galaxy writer Morimi Tomihiko’s bestselling novel The Night is Short, Walk on Girl into a surreal feature true to his distinctive visual style and manic imagination. Upperclassman Senpai harbors a crush on the Girl with Black Hair and tries to advance their non-relationship through "coincidental" meetings. One night, he trails her after a group get-together, but meeting her coincidentally will not be so easy this time. As she wanders restlessly from nightlife to a book fair to a school festival, he runs into a host of strange characters and absurd situations. The night isn’t so short after all in this dazzling and disorienting romantic comedy.
