Bachibachi Kokura Boys

In the year 2023, there were guys in Kokura, the "City of Shura," who were the embodiment of living fossils: Yohei Yokohama, who takes his CBX on dates every night with his blond pompadour hairstyle, and Hyouga Rokkaku, who wields his flamboyant red hair and goes wild in the streets. One day, this Reiwa-era rockin' 16-year-old and this Reiwa-era punk 16-year-old slip back in time to Kokura in 1988 due to a motorcycle accident. And then these boys that had no friends in the present are attacked by Showa-era delinquents!
