in drift contests, earning more points for holding a drift longer or for a quick combination of drifts, but earns no points if the player bumps against the wall or a guard rail. Doing this, the player earns money to buy new cars and modifications. Daytime racing also features racing for sponsors, which includes a kind of racing challenge determined by the sponsor. Beating a sponsor challenge earns the player a sponsor. Sponsors give the player better parts and extra bonuses for winning drift contests. At night, the player can challenge rivals in the parking lot, and race them in a vein similar to Shutokou Battle/Tokyo Xtreme Racer: the first one to have their life bar depleted loses; however, the first racer to cross the finish line will win the race. Through the night, the player will face the "Tricksters", a type of mini-bosses in the course.

But since he was defeated, Koukami moves away to Hokkaido and the Kaido Circuit spirals into chaos. To fix it, in Kaido: Tōge no Densetsu, Zoushigaya becomes the Miracles Summit and now drives a black Subaru Impreza Prototype Rally Car and Kyoichi Imaizumi, Zao's Slasher, becomes the Absolute Emperor and drives a white Renault Clio V6 Phase 2. These drivers are now the fastest on the Kaido Circuit. Meanwhile, the 13 Devils from Tokyo led by Iwasaki come to the Kaido Circuit and have the intention to conquer it. In order to protect the circuit from
