Season 1

Racing team Black Shadow led by the demon king Ahab. The Saionji Racing Team stands up against the villains who will do whatever it takes to win. Ken controls the Hayabusa and defeats Black Shadow's Jack the Ripper. Enraged by the unexpected outcome, Ahab invites Sword to a race across Australia and sets a dastardly trap for him.

The demon king Ahab, angry at Jack the Ripper's defeat, sends Romy, a female racer, to Japan as a new challenger in order to crush the Saionji racing team. Without the doctor's permission, Tsurugi agrees to participate in a hill climb race that he has no experience with. After repeated training, the entire team participates in the battle, but they fall into Ahab's trap and find themselves in a predicament.

The Saionji team participated in a race sponsored by the Le Mans Kingdom. The battlefield will be the Great Limestone Cave Circuit, where once you get lost you will never be able to leave. However, Jack the Ripper steals the king's course blueprints and sabotages the swords. Swords was once on the verge of giving up, but in order to repay the friendship of his friends, he aims for victory!

Under orders from Hayabusa to defeat him, Baron welcomes Hurricane Harry, who had been banished from the racing world, to become a member of Black Shadow. A sword duel with Harry begins on a large ice field at -50 degrees Celsius. Harry aims his sword with a special move. Meanwhile, Homer, who lost the fight with Harry and was fired, plots to kill Ahab and take over Black Shadow.

An invitation to the Agnaria race has arrived from the demon king Ahab. It's a dangerous, life-threatening race through a remodeled ghost town filled with unmanned work vehicles and dynamite. What's more, many of the traps are operated by monkeys, not humans. Still, Tsurugi decides to participate. Join Yamato in a deadly race filled with intrigue!

Thomson, known as the god of racing, was killed by Black Impulse, who drives his opponents to death through team play. When Tsurugi learns that Thomson was the one who taught his brother how to race, he decides to take revenge. Meanwhile, the cunning Baron has prepared another set of Black Impulse as his trump card. Team play has no choice but to fight with team play!

Kamikaze and Gantetsu attempt a race, but not only do they run out of fuel, but their temporary gas station is blown up, leaving them stranded. Baron issues a ruthless order to kill him, but Hawk is unable to lay his hands on the sword that believed in his innocence.

Sakura, who is obsessed with designing a special machine, stays up all night to complete the new machine, Sakura. As soon as the race at Dead Valley began, it was my turn. Since it was difficult to access the steep mountain course at Big Garry and all the important spots had been captured, the Sakura was assigned a major role in refueling.

The Saionji Racing Team, which is on a winning streak, has received an invitation to an oil race in Africa. Since the journey will be tough, crossing deserts and snowy mountains just below the equator, the doctor will conduct an endurance test using a kamikaze machine. Shocked to see his beloved car damaged and broken, Kamikaze returns to his parents' home, but is chased away by his mother who understands the situation. When he returned to the research institute, he was greeted by...

Black Shadow realized that the Hayabusa's weakness was its ability to climb hills, and created a demonic labyrinth course using the underground ruins of Tolteca. The race begins, and the swords that have undergone special training fly smoothly through the vast ruins. However, Baron uses the stone statue that is the keystone of the labyrinth to break down the structure of the ruins, leaving the course suspended in the air due to a large amount of sand!

Angered by the news of his retirement, Tsurugi takes out his frustration at the constant tests on the doctor. The doctor was developing a new V3 engine to overcome Hayabusa's weaknesses. Although the prototype was completed, the experiment failed. Tsurugi, who will be participating in a race in the Himalayas, decides to install a V3 engine on the condition that the engine speed does not increase.

In order to defeat Hayabusa, the Demon King Ahab scouted the lone wolf and skilled racer, the Shooting Star Dragon. Ryu rides to the test course to test the enemy's ability, and takes a liking to the sword, and a strange friendship develops between the two. But a game is a game. Seeing the pebble thrown on the water surface, Ryu comes up with a special move to overcome the Hayabusa by making up for the difference in machine performance.

Tsurugi, who tasted defeat due to Ryu's triple jump running method, devised a single-wheel running method inspired by car chases. The stage for the rematch will be a race on the Iranian plateau. The fierce battle for the top between the dragon and the sword continues. Ken defeats Ryu in a battle over a rocky area, but is faced with a difficult situation due to the course's weaknesses in single-wheel running. If he makes a mistake, he will fall to the bottom of the valley, but he will take part in a high-stakes game!

A man named Will Prague sells himself to the Saionji team as a racer in search of wealth and fame. When the doctor tries to drive him back, Will points out that the reason the Gantetsu can't win is due to a problem with the driver's ability. Iwatetsu is troubled by these words, and before he knows it, he starts to lose himself. What brought him back to normal was the teachings of his father, a martial artist.

A crimson machine suddenly appeared from behind Hayabusa and overtook it in a brilliant manner. It was the legendary car, the Royal Majesty, which had gone missing. The person behind the wheel is Romy, the daughter of the late famous racer Wells. Romy, who has fought with a sword before, challenges him to a one-on-one match at Yatsugatake, hoping to settle the matter this time.

Journalist Atkin, who covered Romy's death, visits the institute. He asks for your help in discovering Ahab's true identity. Rejected by the doctor, Atkin changes his face through plastic surgery and infiltrates Black Shadow, calling himself Lightning Tony. Tony approaches the sword, reveals his true identity, and proposes a match-fixing match. The sword that is troubled by troubles...

The shooting star dragon, who was defeated by the single-wheel running method, continues to train for mountain races under Professor Mephisto. Black Shadow has completed its secret weapon against Hayabusa, the quick cornering wheel. After witnessing the murder of the man who took the blueprints with him, Ryu participates in the Innsbruck race with mixed feelings. Ken also participates and takes on a battle with his archenemy.

After experiencing defeat for the second time at the hands of the dragon, Tsurugi declines the invitation for a comfort trip and remains at the research institute. In order to settle the matter on equal terms with him, Ryu dares to give him the blueprint for a quick cornering wheel. The new V4 engine has already been completed and all that remains is testing. However, due to an unexpected problem, V4 becomes unusable.

The sword was tangled up by a biker gang, and while protecting Sakura, he sustained a wound on his precious left hand. Furthermore, he is given a restraining order as punishment and is prohibited from riding a falcon. Meanwhile, Baron was scouting the Gayla brothers. They are racers who defeat their opponents with a combination unique to twins. The sword's eyesight was taken away by the powerful ultraviolet rays...

Kamikaze, who participated in the All-Japan race, tries his best to show his mother how good he is, and ends up seriously injuring the driver without noticing trouble in the car in front of him. Kamikaze is unable to drive as he would like due to the shock, but the doctor still orders him to get on the machine. Ahab is not going to miss this opportunity and requests to participate in the race on the Great Snowy Mountain.

To put an end to the fierce battle, Ahab takes off his armor and reveals his true identity. He then challenges the Saionji Racing Team on the condition that the loser retires from the racing world. In order to defeat Ahab, the Doctor installs a V5 engine into the Hayabusa. Have everyone master the one-wheel method. And now, the battle for the future of the racing world has begun!
