Earthquakes occur in various parts of Japan. It was nothing but a harbinger of the revival of the Great Kingdom, which once ruled ancient Japan. Queen Himika woke up from a long sleep. Shibahiro, a car racer who survived a major accident, is killed by his father who knows Himika's ambitions. However, his father became a machine father and revealed the existence of the steel Jeeg.

The air during Jeeg's combined training was suffering because he couldn't grasp the timing well. I get tired of it and give up, but the Haniwa phantom of the Great Kingdom kidnaps Mayumi and presses to exchange it for the dotaku once excavated by Dr. Shiba. While destroying the motorcycle, the air is heading to rescue Mayumi. There is no one other than Steel Jeeg who can save her captive!

Queen Himika's anger had reached its peak due to repeated defeats. This time, she plans to eliminate Jeeg and use the out-out boy to get the location of the build base. However, Miwa, who caught the mysterious radio wave, detected an abnormality. A phantom fortress Yamata no Orochi appears in front of her who is heading for the boy's protection, and even Haniwa phantom people aiming for the power plant appear.

A Self-Defense Force plane caused an unexplained crash. Sora brings back fragments of a huge Buddha statue found near the scene and discovers that it is part of the Haniwa Phantom. On the other hand, Himika attacked the complex. The air tries to face it, but it is prevented from going to the flames emitted by the Buddha statue that revealed its identity. Moreover, Yamata no Orochi is approaching from the sea.

Himika plotted to eliminate Jeeg by using a magnetic storm caused by sunspot abnormalities. If you seal the magnetic power, the universe can't even become a Jeeg. At that time, Don, a black eagle who calls himself a rival in the air, was building a mechadon using scrap. When Haniwa phantoms appear, Mekadon starts to play a big role instead of Jeeg.

Sora reunites with his senior racer Hoshikawa in a race with a prize of 5 million yen. Hoshikawa, who is known for his careful driving, is somehow aiming for the championship on this day. I want to get a prize for a girl named Chie who can't walk. When the race entered its peak, Haniwa phantom appeared on the course...

Maki is ordered to investigate the radioactive contamination spreading in Yoshida Bay, but he refuses to go out saying that the chores are not his job. Miwa, who had no choice but to visit the site alone, found a mysterious rock that is the source of pollution. As soon as I approached to collect it, I fell down exposed to radiation. Sora was forced to fight the Haniwa phantom person Tsubute who appeared without a big shooter.

Sora, who appeared on TV, said that he is not a rival such as Don. Don is furious and applies for a duel using a motorcycle. He, who really doesn't want to lose, used cowardly means, so he fell down and hit his head and temporarily lost his sight. Unable to be, Haniwa phantom Droma appeared. Don, who felt responsible, confronts Droma alone.

Without a big shooter, the sky can't become a Jeeg ... Himika orders the executive Amasso and Ikima to conduct a joint operation and make Haniwa phantom Kiira attack Shaboten Park. Kira disappeared once and reappeared. Miwa tried to launch a big shooter, but outside the base, Yamata no Orochi was waiting with a hand shin.

Himika made the executive Mima set a terrible trap for defeating Jeeg. Mayumi, who longed for the snow princess, was lured out by the sound of the whistle blowing by Haniwa phantom flickering, and took her away as a hostage. However, Chirara, who doesn't like conflict, tries to escape Mayumi and fails, and is transformed into a terrible figure by Himika.

The build-based location has been discovered by Himica. The air, tired of repeated movements, is irritated by Miwa, and the ship on which Don and the others are on is swallowed by the vortex that suddenly occurred. The air that went to help encountered a mysterious object at the bottom of the lake. Suddenly, I wonder if my body really belongs to humans.

Do you really have an immortal body? In order to find the answer to the question, Sora dared to fall for the strategy of inviting Haniwa Phantom Goula. The purpose of Amasso, who manipulates Gowler, is to capture the air and attack the build base in the absence of Jeeg. As he expected, the poorly defended build base will be in trouble.

Yamata no Orochi attacked a passenger plane and took Dr. Bose, who was on board, to the Great Kingdom in the way. The doctor was supposed to be the chairman of the World Peace Conference to be held in Tokyo. Himika planned to declare herself as the conqueror of modern Japan through the doctor's mouth. The doctor becomes an intermediary himself and tries to find a way to peace...

Sora learned that he was a cyborg. Shocked, he became desperate and lost his will to fight. Even if a phantom fortress appears, Miwa is forced to face it with a big shooter. Don and Pancho fought hard in Mecadon to help the air captured by the Haniwa phantom Barabba. With the hard work of his friends, Sora finds the meaning of fighting.

Don and Pancho were working hard to make Mechadon have flying capabilities. However, it is worthless efforts and failures. Don gets angry and finally fired Pancho. On the other hand, Himika sent Haniwa phantom Loisa and injured Miwa seriously. Pancho, who likes Miwa, vows to avenge with Mekadon.

Sora, who should have accepted to be a cyborg, but the wounds of his heart that still can't be healed were showing him nightmares every night. If you're not human, are you just a machine to fight? Suffering creates confusion, and the Haniwa phantom Dyra who appeared forced him to struggle. It was the wish and courage of a boy to save his hometown that gave him fighting spirit again.

Don and Pancho decided to ask Dr. Ori to build Mechadon 2 in order to win against Jeeg. Dr. Okura, who is about to complete the sudden construction, appears, and asserts that Mekadon 2 needs an energy amplification device. Don and Pancho took the words seriously and removed the amplification device from the big shooter.

In order to protect the machine father from attack, the development of a momentary object movement device was underway on a build basis. However, the Haniwa phantom Nume released by Himika had already started to invade the build base. No attack can be used for a slime like Amoeba that appears with a mysterious fox fire. Yamata no Orochi appears in front of the air without being able to do it.

Queen Himika revived General Takeru, who was once said to be the bravest in the Great Kingdom. The general's offer to sleep peacefully beside his late wife was not heard, and he turned himself into a Haniwa phantom and attacked the build base. However, as soon as he saw Miwa who went out with a big shooter, he stopped attacking for some reason.

Haniwa Phantom appeared in front of Mayumi who was playing in the park. My best friend Toko's pet was seriously injured. Mayumi always believed that Jeeg would come to help, but the steel giant did not appear until the end, and she suffered a deep wound in her heart. Mayumi was piling up the image of her father to the strong and reliable Jeeg...

Himika has started a strategy to defeat Jeeg with her own hands. I'm going to use Haniwa phantom Razitsu to lure him into the volcano where an abnormal magnetic reaction is occurring. Dr. Sima's instructions, who sensed the abnormality, escaped the difficulty, but this time he is required to come to the volcano mouth with the passengers of the passenger plane as hostage. Carrying the prayer of the hostage's son, Sora goes to the volcanic island where Raset is waiting!

Suspicious tornadoes occur in Ise Bay, causing damage to ships sailing in the vicinity one after another. Miwa, who went to investigate with a big shooter, loses consciousness after being attacked by the Haniwa phantom Gilara who was lurking in a tornado. The air that went to the rescue was also caught by Yamata no Orochi, who was waiting for him. Gilara's magic hand approaching the build base. Mechadon is the only one I can rely on.

Mimashi occupied Mayumi's ferry, and Mayumi and the others were trapped in the hold. Mimai threatens to blow up the ferry with all the passengers if he doesn't hand over the copper taf within an hour.

An incident occurred where people suddenly became violent without warning. It is reported that the poison that flowed out of the build base is the cause, and angry citizens are rushing in. Sora, who went to investigate, was suspicious that only the trees facing the south side of the site were withering, and found out that it was Haniwa phantom Dogera who was dripping poison.

Sora, who participated in the rally, is eager to dedicate victory to his mother Kikue's birthday, but is attacked by Haniwa phantom Daima who suddenly appeared. When he was upset by the neural circuit, it was as if a person had changed. When he escapes while being manipulated by Himika's telekinesis, he approaches the machine father to take his mother hostage and tell him where the dotaku is.
