Flying Colors

is a 2015 Japanese youth comedy drama film directed by Nobuhiro Doi, based on a true story. The film was released on May 1, 2015 in Japan. Plot Sayaka Kudo is a 'gyaru' who wears miniskirts and dyes her hair blonde. Although she is a second year senior high school student, she is on par academically to 4th grade elementary school students. She frequently transferred schools because she was unable to make friends. Eventually she attends a private all-girls high school where she plays and enjoys her extra-scholarly activities while skipping study altogether- here, she is caught and suspended for carrying cigarettes. To prepare her for her university entrance examination, her mother sends her to Seiho Cram School. When her tutor, Yoshitaka Tsubota, hears about Sayaka's academic problems, he makes it his personal goal to help her enter the university of her choice — Keio University (considered one of the most prestigious and difficult to enter universities in Japan) — and to get back at her father. Her father (who aims to get her younger brother Ryuta into pro baseball despite the latter's reluctance) labels her as an "air-head" and says she and her mother are being scammed by the cram school. Likewise, she is repeatedly belittled by her high school teacher, who believes that she is destined for failure. Sayaka becomes determined to study hard to prove them wrong. Over the course of the summer holidays of her second year, through to the exams at the end of her third year in high school, Sayaka works diligently, going without sleep to the extent that she nods off in her classes, forgoing dates with her friends, and dying her hair back to black and cutting it, to show her resolve. Her results progressively improve on practice tests and her academic deviation value increases tremendously from 30 to 70 in this short span of time. Despite facing numerous hardships along the way and nearly giving up, Sayaka, now with her whole family's support, is admitted to Keio University. The film concludes with a comedic montage of the various characters as they sing or dance to the ending song.
