On television are morning talk show hosts, Takehito Koyasu and Etsuko Kozakura (they are the seiyuus of Bancho and Megane!), who were calling each other bugs on air. Mr. Ikusawa walked in the living room and wondered if he was forgetting something. His wife, Mrs. Ikusawa checked if he bought medicine with him. Mr. Ikusawa noticed the guest on the TV talk show. It was Reiji Kageyama, the boy who gave Ruriko flowers. Ruriko walked in the living room and handed a handkerchief to her dad. Ruriko noticed Reiji on TV and became silent. Mr. Ikusawa reminded Ruriko that she was too young to have a boyfriend. "It was nothing like that," Ruriko said in reply to her father's tease. Mr. Ikusawa wished his family take care and promised to work well and give them better life. Apparently, Mr. Ikusawa had just received a nice offer that has to do with the International Expo. Mr. Ikusawa headed out to go with a man who was waiting for him. The driver was not patient in waiting, the moment Mr. Ikusawa boarded the car - the driver drove rashly. On TV, Kageyama broadcast that TV consumers themselves are parasites. (Episode title)

Miss Ochiai served the usual morning coffee to Shirei. Shirei thanked Miss Ochiai while reading a file. Shirei sipped his coffee and frowned. Miss Ochiai was sure that the coffee was made from fresh beans. Shirei was not frowning about the coffee but at the file he was reading. On the file was obviously young Reiji Kageyama. Shirei frowned while he continued to read and investigate. Miss Ochiai apologized about the coffee.

A crowd of fanatic girls gather at Class 2-A's door. They asked Aya, Isogai, and Takanashi if they could join the society or at least have Reiji's autograph. Ruriko and Shun walked along the corridor while talking about Mr. Ikusawa's work at the Expo. Ruriko and Shun noticed the crowd in front of their classroom. "Reiji's really popular." Shun remarked.

In Class 1-A, Kaoru told Fei that Shun was a million times charming than Reiji. Reiji fanatics in their classroom heard Kaoru and frowned at them. "No one is more charming than Reiji!" they said. Kaoru and Fei could not do anything but agree. ("Hhhai.")

In Class 3-A, Reiko was problematic because she forgot something, no, actually everything. Reiko emptied her bag and there was absolutely nothing. Reiko asked her classmates on her left if she could borrow either a notebook or a textbook but they were busy discussing about the general rally. Reiko asked her classmates on her right if she could borrow a pencil or a lunch but they were also busy discussing about Reiji.

Back in Class 2-A, Bancho told Ruriko and Shun that he did not like "pale and city-bred people." (Reiji) Bancho noticed Shun was silent so he asked what was wrong. Shun had not talked with Reiji since the WHK incident. Shun told them that he could not tell Reiji the truth because it was hard for him to be understood. Shun said, "If we can only understand each other, Rurippe." Ruriko heard it and pummeled Shun, and he fell unconscious from his chair! "I haven't seen that in a while." Bancho said. Ruriko assured Shun that they would be smiling at each other once the battle is over. Ruriko asked the collapsed Shun if he was listening. Observing that Shun wasn't moving from where he fell, Bancho said: "I don't think so."

Inside the room of Society for the Study of Political Thought, Reiji was saying that everything was working well in his way. Apparently, Reiji was talking to someone. Shadows of Kikai and Akuma appeared. "Make humans anxious and fearful." Akuma said. "That's why I revived you" Reiji said to them as he recalled the battleship event. "You did it for revenge and we did it for our objective of creating a human farm." Kikai added. Reiji sensed something and suspiciously opened the door. "Who's there?!" Reiji asked at the top of his voice, with a scary face. Reiji noticed that it was just his three co-founders. Aya, Isogai, and Takanashi was a little frightened with the way Reiji answered the door. Reiji's voice turned into a kind tone and he smiled at them. Reiji apologized and said he thought they were the paparazzi. The trio became relieved and they reported that 10000 participants from all over Japan were coming to the rally. Reiji thanked them and told them that they were special to him. The trio blushed.

Mr. Ikusawa was thankful to the Expo Organizer that his small firm, Ikusawa Construction, got offered by the International Expo. The Expo Organized was not responding to him. Mr. Ikusawa began to notice workers playing around the pavilion. "Seems we're short of labor due to economic boom." Mr. Ikusawa said. "What's your problem?!" asked the organizer annoyingly. "From now on, this will be the International Expo…of HELL!" the organized changed into a red Invader while the rest of the workers changed to the black Invaders.

Shirei called for the Gate Keepers Party. Shirei informed them of the Invaders ravaging the International Expo, 30 minutes ago in Osaka. Shirei noticed Ruriko's reaction and asked the problem. Ruriko told him that it was nothing. Shun remembered that Ruriko's father was working at the International Expo. "It's the festival of progress and harmony, protect it from the Invaders!" Shirei sent the Gate Keepers out to make a sortie.

Two helicopters seen above the sky. One helicopter was carrying the AEGIS bus. Inside the other helicopter were Shun and Megane. Shun asked Megane if the helicopter could be faster. With the Gate Robo aboard, Megane said, it was impossible. Shun called Ruriko, who was inside the bus (hanged in the other helicopter) told her not to worry. Shun cautioned Megane to hold tightly. Shun opened his gate of gales. Their helicopter entered the wormhole formed by Shun and it accelerated greatly.

AEGIS operators reported to Shirei that the helicopter was flying at 1.5 times the speed of sound and it would be arriving at the battlefield within 17 minutes. Shirei was worried that the helicopter would not be able to take the speed.

The helicopter had finally arrived at the mission location but the chassis was scraped into pieces and it crashed. Fortunately, Megane and Shun landed safely with the Gate Robo. The place was dark and quiet. A crane moved itself and pushed Gate Robo. Shun thought it was the enemy. Megane noticed a man on top of the pavilion being held by the red Invader. Shun recognized he was Ruriko's father. AEGIS Bus had arrived. It transformed into a battle bus. The Gate Keepers inside the bus noticed the Gate Robo climbing the pavilion. Kaoru jumped out of the bus and took metal grills. "Kaoru Javelin Throw!" The grills attached to the pavilion helping Gate Robo to climb. Fei attacked the pavilion's base with Fire Dragon. "Hikari no…" Ruriko followed but the tip of the pavilion turned to her and she noticed her father. "Father!" Ruriko exclaimed. "What, that's Ruriko's father?!" they all screamed. Because of the pavilion's movement, Gate Robo lost its balance and fell down inside the pavilion's body. The AEGIS Bus and other nearby things were slowly absorbed by the pavilion. Ruriko fell off the bus. Megumi jumped out and cushioned Ruriko's fall with her "Wall of Shock Buffer." "You always cause me trouble!" Megumi said. "Help me, Ms. Ono!" Reiko screamed as she was being dragged inside the pavilion.

AEGIS operators reported that the Gate Robot and AEGIS bus were already absorbed by the pavilion and it increased its mass by 20 %. AEGIS Operators lost their signal due to interference waves. Shirei thought it was not the normal tactics used by Invaders. "Could it be Shadow?" Shirei thought.

"We're inside the body of the pavilion!" Megane cried. "Good!" Shun said and attacked with Vacuum Missile. Gate Robo's power decreased to zero. They realized that the pavilion was absorbing energy. Fei tried with her Fire Dragon. It did not work either. Instead Fei wobbled, feeling her energy was taken away from her. Megane realized attacks would not work. Bancho screamed that he had not shown his power yet. Shun warned Bancho not to yell or else he would lose his stamina. Then Shun realized voice were not absorbed. "They are echoed!" Megane approved. Kaoru got an idea that illusion would work. Everyone looked at Reiko. Reiko had her usual ignorant look.

Megumi told Ruriko that Invaders were absorbing the Gate Keepers energy. "Can't you hear? Listen." Megumi ordered Ruriko (screaming Gate Keepers heard), "It's funny, you're rich, popular, and a top student, and yet you are not able to save them."

Reiko took out her portable piano it appeared to be an abacus (I'm not really sure if it transformed or it was because Reiko forgot her piano). "Hail Vader!" Kikai Shogun's famous line. Shadows of Akuma Hakushaku and Kikai Shogun appeared. "We have been waiting for you. This will be your grave!" Akuma Hakushaku said. Shun could not believe it because he had beaten them. Akuma Hakushaku stated that they would never vanish as long as humans have infinite desires. Akuma Hakushaku showed what was happening outside the pavilion. On a shadowy screen were Ruriko and Megumi. Akuma Hakushaku remarked that Ruriko was a coward because her father was in custody, while the other one is… Without continuing the remark, Akuma invited them to become a part of the pavilion. Kaoru accelerated toward Bancho and took him. Then Kaoru jumped to Shun and took him also. Kaoru threw Bancho and Shun upwards, away from the pavilion's body. "We are counting on you!" Kaoru told them.

Megumi told Ruriko she was worse than a speck of bug. Megumi could not forget about Fukuoka-sensei and still blamed Ruriko for it.

Bancho and Shun arrived at the top of the pavilion. Bancho and Shun ran up to save Ruriko's dad. They were slowing down the moment they get higher so Bancho stopped and pushed Shun.

Ruriko's face was fallen, she did not know what to do. Ruriko held her bow and arrow then pointed at the red Invader. Megumi asked if she would really destroy the Invader along with her father just to save the world. Tears fell down from Ruriko's eyes. "Your faultlessness makes me sick!" Megumi yelled, "True Self!" Megumi's face turned evil and she unleashed a dark gate then she penetrated Ruriko's heart.

Shun continued to run until he got to the edge. Shun jumped to the red Invader and took Mr. Ikusawa. Shun called out to Ruriko that her father was safe. Ruriko was still pointing the arrow then she released it. "Ruriko, your father is fine!" Shun assured Ruriko as he ran down. Ruriko heard Shun. The arrow went past the red Invader. Ruriko begged her arrow to hit the Invader. The arrow acted according to Ruriko's command as it turned back and hit the red Invader. Bancho and Shun quickly ran down before the pavilion they were running on would disappear. The pavilion slowly disintegrated.

"Rurippe, I kept my word" Shun said in his mind. Mr. Ikusawa was taken into the ambulance. Kaoru, Reiko, and Fei informed Shun that Megumi and Ruriko were missing.

Megumi and Ruriko appeared before Reiji. Ruriko was enveloped inside a green substance, possibly the green wall of Megumi. "She closed her gate and locked herself in the depths of her heart." Reiji said. Reiji turned to Megumi and told her he needed her to work for him more. "Fine. As long as you truly appreciate me…" Megumi said as she wrapped her arms around him. Reiji grinned.
