Because of his delinquent-esque looks, he was feared by his classmates, has made no friends, and his greatest regret was not joining the ouendan (cheer club), which was now disbanded. After an accident on the day of his graduation, he and classmate Fujieda Aki are transported three years back in time, freshman again in body but with high-school memories intact. Can Imamura fix the mistakes of his past? Can he re-do his high school years in the way that he's always wanted? Again!! The universe suddenly shouts.
