OVA
Description
Hijiri Minowa, heir to the Minowa Group, possesses considerable wealth and resources. Her affluent lifestyle features commuting to middle school by helicopter and being escorted by her family butler, Hayakawa, who initially transports her in a Ducati 750SS Imola Replica sidecar. Despite her privileged status, Hijiri aspires to project a rebellious or delinquent image, though her inherently kind nature frequently causes her actions to undermine this ambition.

She obtains a motorcycle license before Japan's legal age through alleged foreign bribery and subsequent domestic transfer. Fellow Okanoue Girls' High School Bike Club member Onsa Amano revokes this early license by destroying it upon discovering Hijiri's lack of basic road knowledge, such as a yellow traffic light's meaning. After turning sixteen, she legally acquires a moped license. Her initial riding experience involves a Honda Super Cub 50 equipped with training wheels and a cattle skull accessory, accompanied by two support vehicles for safety. Frustrated by the Cub's limitations, Hijiri demolishes it with a sledgehammer; it is later repaired and returned to her with ongoing stability modifications.

Upon mastering riding fundamentals, she upgrades to a Ducati 1199 Panigale S. To comply with Japanese regulations restricting minors to sub-400cc motorcycles, this high-displacement bike is custom-tuned to meet legal requirements. Her progression from novice to licensed rider occurs alongside her participation in the Okanoue Girls' High School Bike Club, engaging in group activities like touring Hokkaido and school events.

Her primary relationship is with her butler and guardian, Hayakawa, her initial transporter. Within the Bike Club, she interacts with members including Hane Sakura, Onsa Amano, Rin Suzunoki, Raimu Kawasaki, and Chisame Nakano.

Her family name, Minowa, combines the characters for "three" (三) and "ring/circle" (輪), while her given name, Hijiri, means "holy" (聖). She stands 160 cm tall, has blood type AB, measurements of B81-W61-H86, and a birthday on December 23.
