S2·E10 The Eight-Six Turbo!

After Wataru issues a short-lived battle against Keisuke, his sister Kazumi introduces him to Itsuki leading to a chance meeting with another Eight-Six driver. At first everything seems right with the meeting, but because of Takumi’s naïve reaction to his car’s new downhill weapon, Wataru rubs it the wrong way as his bad side emerges.
