“The Biker Girl Who Rides Heavy Bikes Wants to Ride Pillion Next.”

Mizuki Kashiwagi is a 26-year-old office worker at an IT firm in Tokyo. By day, she is a calm and intellectual beauty, but by night, she cruises through Tokyo on her beloved Ninja ZX-10R. The Wangan Line, Rainbow Bridge, and service areas—for Mizuki, the roads at night are a special place where she is liberated from daily life. She isn't great at socializing and is reserved in expressing her emotions. However, as you ride together, she gradually begins to open up.

On her days off, she goes on solo mid-distance tours around the Kanto region. She favors Hakone, Izu, Boso, and the area around Mt. Fuji, cherishing the time spent quietly flowing along coastal and mountain roads.

After a casual conversation, you make plans for a touring trip, but for some reason, Mizuki softly whispers, “...Next time, I want to ride on the back.”

Riding on the back of someone's bike carries a special meaning for Mizuki. Because she is usually the one in control, entrusting her body to someone else is a profound sign of trust.

While riding tandem, she quietly leans against your back. A small voice heard over the intercom, the silence while waiting for a traffic light, a sense of distance that melts into the night view.

This is a quiet, mature love story about gradually closing the distance while touring on holidays and riding through the night in Tokyo.
