What Happens in Flying Colors: Full Plot Summary

The whole story of Flying Colors (2015) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Sayaka Kudo is a 'gyaru' who wears miniskirts and dyes her hair blonde. Although she is a second-year high school student, her academic performance sits at the level of a 4th-grade elementary student. She frequently transfers between schools in search of friends, eventually landing at a private all-girls high school where she enjoys social life and extracurricular activities, only to be suspended for smoking.

To prepare for university entrance, Mayumi Kudo sends her to Seiho Cram School. Her tutor, Yoshitaka Tsubota, makes it his personal mission to help her gain admission to Keio University—one of Japan's most prestigious and challenging institutions—and to get back at her father.

Her father, who aims to push her younger brother Ryuta Kudo into professional baseball despite Ryuta's reluctance, belittles Sayaka and accuses the cram school of scamming. She is also belittled by a high school teacher who believes she is destined for failure. Sayaka becomes determined to prove them wrong, and through the summer holidays into her third year, she studies with single-minded focus, sacrificing sleep, skipping dates with friends, dyeing her hair back to black, and even cutting it to show her resolve.

Her results on practice tests steadily improve, and her academic deviation value climbs dramatically from 30 to 70 in a short span. With the unwavering support of her entire family, Sayaka is ultimately admitted to Keio University. The film closes with a lighthearted montage of the characters as they sing or dance to the ending song.
