In 1963, a strange floating soldier appeared before a cargo ship that sailed in the middle of Bermuda Triangle. The drunken sailor who saw him was not half terrified, instead he asked, "Are you a soldier?" The strange floating soldier corrected him, "No, I am General!" After that the soldier landed his feet to the cargo ship, and started to release tentacles that wrapped the sailor and the cargo ship. The ship drowned in the ocean. Six years later, the cargo ship's remnance was seen floating near Japan. (Episode Title)

The bullet train zoomed along Kyoto. Aboard the bullet train were Shun, Saemi, and their mother. Shun pointed a tower through the window to Saemi and told her that it was the Kyoto Tower. Saemi told him that he said the same thing when they passed there. Shun wondered, "Oh, I did?". Saemi told him that she wanted to go to Kyushu next time. Shun told Saemi not to be humble and that if he wins the lottery, he will take her to Kobe. Their mother, who handed Shun a cold orange, reminded them that she was the one who won their trip in the lottery. Shun tossed the cold orange in each of his hands, and finally passed it to Saemi. Saemi enjoyed the feeling of the cold orange when she neared it to her cheek.

Meanwhile, in the AEGIS base, Shirei showed the seen cargo ship, Marine Sulfur Queen that had been lost in the Bermuda Triangle 6 years ago, to the Gate Keepers (minus Shun). The Gate Keepers asked how it arrived in Japan if it was from Bermuda Triangle. Shirei hypothesized that it had possibly crossed time and space. The AEGIS workers detected an electrical wave that tried to synchronize with their frequency. A strange wave was detected and was confirmed to be 5000 times stronger that the normal strange waves they had been receiving. On the screen appeared the soldier that destroyed the ship. Shirei was startled and introduced him as Kikai Shogun (General Machine). Shirei described that Kikai Shogun was one of the Invader Staffs that had the ability to fuse with machine, and he was one of the cause of the many disputes in Japan. Reiko remarked that Shirei had finally met an acquaintance (^_^;). Shirei asked Kikai Shogun how he passed through AEGIS' surveillance network but realized, before Kikai Shogun answered, that Kikai used the cargo ship. Kikai Shogun greeted them with a surprise. The screen changed to the scene of the bullet train, callsign: Hikari, then he told everyone that he would keep the train run faster than the speed of sound. Everyone became alarmed because technically, the bullet train would destroy the Tokyo Station terminal if it exceeded the speed of sound.

Shun just got out of the toilet, amazed that it had a flush. Then Shun noticed paper cups near the door, so he took three as a souvenir from what he called "The Express of Dreams" (bullet train). Suddenly, the train operator's voice was heard all over the train, informing the passengers that they would arrive shortly in Nagoya, but the voice changed and said that the train would never stop to Nagoya again. Kikai Shogun had taken over the train and was planning to convert the train into a train of terror.

Back in the AEGIS Base, Shirei asked the AEGIS Operators if they were able to send emergency controls. The operators informed Shirei that there was no signal so they had not. Shirei instructed the operators to inform everyone to evacuate all stations. Miss Ochiai reported a bad news to Shirei. According to Miss Ochiai's report, Shun Ukiya happened to be one of the passengers of the bullet train, Hikari. The Gate Keepers were shocked to hear this.

Kazuko Ukiya and Saemi were waiting for Shun in their seats when the other passengers started to panic. Every passengers panicked at the thought that the brake was malfunctioning. Just outside the bullet train was Scouting Helicopter 301. It was monitoring the bullet train's transformation. However, a hand appeared from the transformed train and clawed the scouting helicopter. The helicopter operator sent his feedback to Shirei that he was unable to chase the bullet train anymore. Miss Ochiai informed Shirei that the GateKeepers have already arrived at Tokyo Station.

In Tokyo railways, the Gatekeepers were preparing for the bullet train's arrival. The railway opened a portion and revealed a steam locomotive from the underground. Reiko commented that it was old fashioned, while Megumi admired it for is classic look. Ruriko asked Megane (who was inside the steam locomotive) if they were really going to use the steam locomotive against the bullet train. Megane told them never to underestimate the Electric Locomotive BB9004 as it had a speed record of 331 km/h. Megane informed them that AEGIS France lent it to them. Bancho appeared inside the steam train window and pressed a switch in his hand that revealed the Gate Engine behind the train's open compartment.

Shirei got the information from the helicopter operator that only the front car combined with Kikai Shogun. Shirei had thought of a plan already. Shirei assigned Kaoru to slow the train with her Close Combat ability, while Fei would use her Gate of Red Heat to cut the connector between the front car and the passenger cars. Based on speed and geographical features, Shirei chose the Tama River as the interception point.

Shun tried calling AEGIS, but there was no signal. Kikai Shogun appeared and handed over his 'gift' to him which happened to be 2 Invader robots. Kikai Shogun introduced himself to Shun and told him to come to the power car if he wanted to stop the train.

AEGIS party prepared a fuse along the railway while the GateKeepers party prepared the steam train. Ruriko took the lead in the absence of Shun. Ruriko asked everyone how they were doing - Megumi sulks in the corner about why Ruriko had to order them around. Bancho was connecting two wires, but Fei warned him that negative opposes each other. Bancho had already connected the wires, he was burned and said that he was Gate Super so he was not good at tricky things. Fei praised Bancho and remarked that he was immortal. Ruriko noticed Kaoru who was excercising hard while thinking of Shun.

The robots surrounded Shun while computing that their winning probability was 81.6%. Shun took out his wooden sword but the robots read his movements in advance and took his sword away. After taking away his wooden sword, the robots computed that their winning probability had increased to 98% as they have sealed his Ultra Whirlwind Slash attack. Shun realized that they have been reading his fighting style.

Kaoru stood on the Gate Engine as she waited for the train. The train would arrive shortly in 5 minutes and 32 seconds.

Shun, having no weapons in his hand, thought of an innovative way to beat the robots. Shun picked up two metal thingies (I can't figure what it is), and then attacked with his 'whatever-move' - Double Ultra Slash! The robots had not read that new move - so they definitely lost! Shun opened the door to the front car. As Shun entered, he noticed that the front car did not look like what it was supposed to look like. The front car was terrible, full of ugly wires entangled to each otehr. Suddenly, metal wirings wrapped Shun up. Shun complained to Kikai Shogun that he was unfair that he did not show himself to him. Kikai Shogun showed his face and said that the front car was him.

As the train was nearing, Kaoru started opening her gate. Ruriko commanded everyone to start the mission. Kaoru shouted the name of Shun as she pushed the train. Megane started the steam train alongside Hikari as Fei unleashed her red heat to the train connector. The heat of her Fire Panda melted the connector and separated the passenger cars. Reiko talked nonsense that her Dazzling Melody would now destroy the enemy, then as she was about to play, the front car had passed already (this always happens!). Kikai Shogun had not have the chance to hear Reiko-chan's wonderful music! Ruriko asked Megane if they could catch up with the bullet train, but Megane told Ruriko that was all the steam train can do. The power connection of the Gate Engine to the steam train was removed as Kaoru was being pushed back by the front car. Even without the Gate Engine's power, Kaoru was amazingly retaining the amplified power.

Shirei took out something that looked like a bomb box (possibly a thing that's connected to the fuse setup by the AEGIS Party) as he watched the failure of Kaoru to stop the train.

Kikai Shogun asked Shun where he wanted to die — either inside the train or in Tokyo Station. A sharp metal was pointing at Shun, ready to jab him, but Kaoru yelled at Kikai that he would not let Shun die in her presence. Kikai Shogum told her that she would not be able to do anything since the Gate Engine was now useless. Kaoru disagreed and told Kikai Shogun that she had learned something from Shun and that was not to give up. Kaoru punched the front car, but the front car's claw pushed her back to the Gate Engine. Kikai told Shun that he would kill Kaoru first. Shun yelled Kikai Shogun's name and Kikai Shogun faced Shun. Shun opened his gate and threw a paper cup to Kikai Shogun. The paper cup fastly slashed through Kikai's left cheek. Green ooze spilled from Kikai Shogun's cheek. The paper cup made a diagonal mark in his left cheek, which completed an X-mark since Kikai Shogun had a diagonal mark before. Shun asked Kaoru if she was all right. Kaoru told Shun she was fine and asked him if he was injured. Shun went near the window and showed her that he was also fine. Inertia pushed Shun back, and then Kikai Shogun reappeared and told him that there had been few humans who had hurt him and they were all sent to hell by him. Kikai Shogun disappeared to the sky and the front car changed back to normal. Kaoru pushed the front car and Shun helped her by pulling a lever down. The train finally stopped.

Shirei released his breath as he cancelled pushing the switch of the bomb box. Miss Ochiai smiled and told Shirei that she would prepare a special coffee for him.

In Tokyo Station, Kaoru ran to Shun and hugged him. Saemi, with Kazuko, appeared and asked Shun if Kaoru was her girlfriend. Kazuko told Saemi not to be nosy while patting her head. Kazuko continued that there had been a lot of thrills that happened for a lottery prize. Kaoru introduced herself to Kazuko. Kazuko told Kaoru that she was a pretty girl. Kaoru was flattered at what Shun's mother had said, and quickly clutched Shun's arm. Saemi was still fixing her hair that was ruined by her mother's patting. Shun gave a paper cup to Saemi and told her that she could show it to her classmates. Shun saw Ruriko who was organizing the crowd in Tokyo Station. Shun asked Ruriko if she wanted his last paper cup that came from the "Express of Dreams". Ruriko smiled but looked away from him ("Hmmph!"). Kaoru was still clutching to Shun's arm (that's why).

Shirei told Miss Ochiai that Akuma Hakushaku had appeared the other day, now it was Kikai Shogun. Shirei stated that Invader executives had never appeared to one country so much as they did in other countries. Miss Ochiai asked Shirei what would be happening to Japan now. Shirei had no idea.
