Tear through the Hakone Tsubaki Line with the girls.
About
Setting: Tsubaki Line, Kanagawa Prefecture, Japan The story takes place on the Tsubaki Line, which stretches from Yugawara Town toward Hakone. In reality, the Tsubaki Line is part of Prefectural Route 75, the "Yugawara-Hakone-Sengokuhara Line." Official records define the section from the "Tsubaki Line Entrance" to the "Hakone Checkpoint South Intersection" as a stretch of approximately 18.5 km. In this work, the Tsubaki Line is depicted as a mountain pass where skilled drivers gather at night. During the day, it is an ordinary mountain road frequented by tourists and general traffic. However, deep into the night, it reveals a different face known only to car enthusiasts. Worldview In this world, car culture is deeply rooted throughout Japan, and there are many young people who love sports cars. Particularly around Hakone and Yugawara, sports cars with distinct personalities gather, such as the Roadster, RX-7, NSX, Fairlady Z, Lancer Evolution, and GR86. Standing out among them is "NOCTURNE," an all-female driver team. Their ages, personalities, and driving styles are all different. But they share one thing in common: "I want to prove my own speed with my own car." That was the sentiment that brought them together.

Her driving style is a precise grip run that cuts out all waste, conquering high-speed corners with weight transfer and minimal steering. Her car is a Championship White HONDA NSX-R GT. An MR, 6-speed MT car equipped with a C32B V6 DOHC VTEC, it features a dedicated wide body, carbon aero, a huge rear wing, and a "chonmage duct" on the roof. It is Rin's one and only partner.

Her car is a Spark Red TOYOTA GR86. Equipped with an FA24 2.4L flat-four, FR, and 6-speed MT, it is a light-tune spec with a muffler, coilovers, brake pads, lightweight wheels, and sports tires.

She started running the pass out of admiration for Rin, Rena, Mio, and Yume, and is a promising rookie growing steadily while learning from her mistakes. She keeps driving with the motto "Faster today than yesterday" in her heart.
