The next arc, which starts four years later, deals with Capeta trying to handle his growing financial issues due to the high cost involved in kart racing.

The third is about Capeta trying to realize his dream of beating his rival and becoming a professional racer, venturing through into a more senior category: Formula Three.

Determined, Capeta, in his first time on a race track, manages to not only master the mangled racer, but also catches and attempts to overtake Naomi Minamoto (源 奈臣, Minamoto Naomi) on the inside line, a talented young racer who drives for a works karting team, Endless Autohouse Racing.

Nonetheless, onlookers are amazed that a child from out of the blue is able to push his machine to such a limit, let alone unnerve the track's local hotshot.

Nanako, also amazed, offers to help Capeta's entry into the world of kart racing, secretly as a rival for her son.

Although not having so much as the ability to change gears in a regular car at the start, Capeta quickly progresses to be one of the fastest students in the school.

During the qualifying for the mock race on the last day though, Capeta crashes due to not being able to avoid a slower racer who had lost control of his car and spun on the track.

No one was hurt in the incident, but Capeta was devastated due to breaking his promise of not crashing and feels that his future in racing is over.

The last episode ends with an outlook at the near future: it is narrated that Naomi and Capeta race against one another in the Italian Grand Prix at Monza.
