By 2048, motor racing has evolved into a popular fighting race called IGPX, a competition of humanoid high-speed mechs running at 600 km/h. As the winner of the IG-2, Team Satomi is now joining the top league, the IG-1. But on the other side of the shining glory, the young team suffers for a total lack of teamwork. To begin with, defense pilot Liz does not get along with Takeshi, the forward; they always get into fights. And when Takeshi meets with Yamma, from the next opponent, Team Sledgemama, he gets a harsh greeting. Will Team Satomi make it in the IG-1?
The new IG-1 season opens. The first opponent for the rookies of Team Satomi is Team Sledgemama, known for its rough play. While Sledgemama's leader Yamma relentlessly aims at Takeshi, Liz and Amy desperately fight back, but the battle in the IG-1 is tougher than anybody in Team Satomi had imagined. Takeshi looses confidence and the team spirit slumps for the worst. Then a depressed Takeshi meets "Princess" Fantine from Team Skylark, the idol of the IG-1.
"Withdrawal from the IGPX" was the decision of company headquarters. Team manager Satomi Satomi is astounded. The board of directors only gave the team one day. The race has already started, so Satomi leaves for the racetrack, but she can't keep calm inside. Now at the race, the opponent Team Black Egg takes an aggressive defense-only strategy. Takeshi and his teammates encounter difficulty shaking off the tough defense. Can Team Satomi "crack the egg"?
The brain of Team Satomi is Amy. She has been called a genius since she was little, but she has a problem she would never tell anyone. Meanwhile, Takeshi is walking along the racetrack and meets Team Satomi's next opponent, the champion team Velshtein's Cunningham, who graciously tells Takeshi, "there's a whole world of difference between our abilities." Takeshi is baffled. How is Team Satomi going to challenge the dominating team Velshtein?
The second pilot River is restless thinking about Team Satomi's match with the champions of Velshtein and his present position in the team. "I will drive the forward machine. Nothing will stop me!" Meantime, Satomi has gone to see someone for some crucial parts for her mechs. But this turns to be a stubborn old man and gives Satomi a hard time. Late at night in the mechanic room, River climbs on the forward machine... What are his intentions? Could Team Satomi get new machine parts on time?
The next opponent, Team Edgeraid, is skilled at making strange and acrobatic moves. But there is more. As Amy enhances her abilities by riding an IG machine with Luca, Edgeraid's forward and team leader Bjorn pilots his machine supported by his dog Sola by his side. This next race is going to be a unprecedented competition between a dog and a cat! How is Team Satomi going to fight back the invisible attacks of Team Edgeraid? Meanwhile, Satomi receives a visitor in her office...
Masa, the chief mechanic with Team Satomi, is being paid an unexpected visit by his father, who is bringing sad news: "Your mother has taken ill." Masa is shocked, but something is refraining him from rushing home. Meanwhile, the annual IGPX Festival is being celebrated the race track. But when Takeshi is about to start a test run to set the machine, the mech gets into trouble! Could Takeshi finish the course? What is Masa's secret? And why is Fantine suddenly approaching Takeshi?
Team Satomi's next opponent is Team Skylark, but at the time, the paparazzi have already scooped that Takeshi is dating Fantine, Skylark's charming forward pilot. The world's attention is now concentrating on the two young pilots even before the race starts, but this situation is apparently disturbing Liz, who gives a complicated gaze towards Takeshi. What will Liz do during the race? What will happen to Takeshi's relationship with Fantine? Meanwhile Satomi, who became suspicious about the new sponsor, finds a shocking truth...
