Akio, who works at a gas station, earned his large motorcycle license and finally got his hands on the GSX1100S KATANA he’d always wanted. Devoting more affection to his bike than to his girlfriend Risa, he silently continues to test-run the engine. One day, Akio meets Mioko, a tough-talking junior at Risa’s high school. She had a crush on Akio’s friend Takashi, but at the same time, she had caught the eye of Kikuchida, a member of a delinquent gang.
