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.

When the little one learned that the kitchen of the Sima family was in pain, he left the house because he couldn't cause trouble. Knowing that, Sora desperately starts looking for the little one, but is seriously injured by the arrow of Haniwa phantom Garros, who was ambushed. On the other hand, Himika is angry when she learns that the universe is alive and sends Garros again to take his life at all costs.

Sora, who devoted himself to special training by his father's order, fell beyond the limits of his mind and body. The hospital that was taken was occupied by Ikima and others who received Himika's order. Sora was given numbness medicine and fell into a predicament, but he succeeded in escaping with the success of Miwa who rushed to it. While fighting against Ikima and Mimash, I will make a new transformation while being guided by my father's voice!

Himika finally found out the hiding place of the dotaku. Sora proposed not to wait for the opponent's attack, but to attack the great kingdom in the way from here. However, Dr. Shima dismissed it because the opponent's strength did not grasp his personality. The air that can't give up goes out with a big shooter without listening to orders and goes to Kyushu, the place where the dotaku was found.

With the development of new weapons, Jeeg succeeded in powering up. Finally, I decided to get into the Great Kingdom, which is the home of Himika. Before the battle for the future of Japan, the build-based members are united for victory. However, Himika was using his telekinesis to solve the mystery of the dotaku. A new enemy appears from the entrance of the sealed dragon.

Miwa, who was given a kimono as a gift from Kikue, remembered her mother who broke up when she was young. I couldn't see that Miwa. She went to the amusement park and was captured by Haniwa phantom Modoki. Modoki disguises exactly like Miwa and gives Jeeg a terrible trick. Sora goes out after receiving the news of the enemy's attack without knowing anything.

Unexplained accidents were continuing in various parts of Japan. Mayumi's bus was also involved in an accident, and Toko-chan was seriously injured. It seems to be the work of the great great power. The angry air rushed to the scene after learning about the accident of a passenger plane that occurred over Mt. Fuji. Bardo, a robot beast hiding underground, attacked and destroyed the Mach drill.

Mekadon, who went to investigate Yamakawa Dam, found Yamata no Orochi. We will face General Flora, who has been fighting with the robot beast Doran, using the new weapon marine parts. At that time, Mimashi was revealing the truth of Himika's death to Ikima and Amasso. The Haniwa army took advantage of Flora's absence and rebelled against the Dragon Demon Emperor and forced him to abdicate!

Amasso and Ikima, who were imprisoned for treason, escape from prison to ask for forgiveness by defeating Jeeg. He planted a bomb on a car in the air that participated in the race, disguised as Don and Pancho and rampaged with Mechadon. The bomb will operate when it reaches 80 km/h or less, so the air must be removed while driving a car. Even the robot beast and the hijacked Mechadon appeared...

Dr. Shiba was devised new measures for the increasingly fierce battle. However, Sora is careless because of the increase in Jeeg's strength. As if poking there, Flora sent a robot beast Gokira to the special steel factory. If the reactor is destroyed, it will be a big deal. Jeeg struggles, and Dr. Sima activates the evacuation capsule.

Flora made the robot soldiers attack the family in the air to seal Jeeg's movement. Director Ori thought about the future and proposed to evacuate his family on a build basis. Sora refused it, but he was afraid that his family would get involved, so he couldn't sortie even if the enemy appeared. My mother preaches to him the real role of his family and admonishes him to fulfil his mission.

The phenomenon of flowers dying in cold air continues. Sora, who met Hiromi, a girl with leukaemia, knows that the only remaining black rose is the support to live, and promises to protect the flowers. Flora uses it and stands in front of the air heading to the hospital. In the middle of a one-on-one battle, Sora unexpectedly learned about Flora's sad past...

When Sora heard Flora's call, he asked Miwa to launch a big shooter to the underground kingdom to have a discussion. However, there was a trap of the Dragon Demon Emperor on the way. Ikima, the robot beast Dodon approaches the air trapped in the volcano by Amasso's ploy. Flora, who suffers between fear of the emperor and conscience...

Amasso returned the boy's fossil to a human form with magical power and sent him to the museum where the mammoth fossils he once had a good friend were enshrined. The boy shoots a fire arrow, and the mammoth fossil becomes a Haniwa phantom mammo and starts a rampage. People who panic and run away. The air that confronts is hesitant to fight against a boy who is not originally an enemy.

While piloting the big shooter, Miwa's physical condition changes. Kikue invites Miwa, who got a vacation, to go shopping and buys a dress at a department store and gives her a present. The department store was attacked by the robot beast Dorila. The two evacuated are surrounded by robot soldiers led by Flora. Although she manages to repel it, Miwa falls down again.

Duel held in the underground kingdom, the robot beast brothers Reds and Blacks were chosen as Jeeg's assassins. On the other hand, on the ground, Mayumi's puppy had disappeared. Mayumi gets acute pneumonia because she searched around in the rain. I entrust a pendant to Mayumi, who suffers from nightmares due to high fever, and Sora challenges the brother of the robot beast to fight!

While the air were enjoying a brief holiday, the invasion plan was steadily progressing in the underground kingdom. Ikima succeeded in summoning Himika's soul. Himika's soul transfers to the robot beast Raygon and drags Jeeg into a different dimension graveyard. The Haniwa phantoms who once destroyed attack Jeeg, who was deprived of his power by spiritual power!

A huge meteorite fell to the ground. Sora and Miwa, who went on reconnaissance, witness the appearance of the robot beast Jean from the meteorite. Jeeg, who was lured by Jean, is wrapped in pieces of magnetic rocks and transported to the space waiting for the Phantom Fortress. The Dragon Demon Emperor, who is convinced of victory, takes the command of Jean himself and embarks on the capture of the build base.

Sora, who was invited to a flying hotel, was caught in Flora's trap and took a paralyzing medicine. Flora tries to blow up the air, but when she is told that the Dragon Demon Emperor is not a benefactor but an enemy who slaughtered his parents and brothers, she escapes the air from the phantom fortress. Flora, who broke up with the Dragon Demon Emperor, remains in the fortress and tries to atone for her crimes.

The Dragon Demon Emperor, who lost General Flora, raised the four strongest four kings of Haniwa Phantom to a blood festival and went to the front on the Dragon Demon Ship. Before the approaching decisive battle, Sora says goodbye to Mayumi, her mother and Dr. Shiba sends out such a space with the mysterious words "die and live". Although the air that sortied advances to the air battle, it is hurt by the dragon demon emperor's sword and falls down.

The Dragon Demon Emperor has gathered all Haniwa soldiers and robot soldiers and launched an all-out attack on the build base. The Dragon Demon Emperor demands the abandonment of the build base, but Dr. Shiba resolutely refuses it. If you go out with a capsule, you will rush into the phantom fortress. Now, Sora, who inherited his father's will, is embarking on the last battle with the Dragon Demon Emperor!

Himika, the queen of the Great Kingdom, who had been sleeping for a long time, was revived, and Dr. Sima, who was expecting it, made a steel Jeeg. The sky, which was turned into a cyborg by Dr., transforms into a steel Jeeg and defeats Himika by joining forces with his partners Miwa, Buildbas, and Mechadon. And I will bet everything on the further enemy, the Dragon Demon Emperor.
