The alarm clock ringed six in the morning. Ruriko woke up and stretched a bit. Ruriko opened the window to greet the birds, but she saw Shun half-naked in the opposite window. Shun explained that the dormitory was full so Shirei assigned him in the guesthouse next to Ikusawa Residence. Ruriko realized she was in her nightdress so she threw things at Shun and yelled "PERVERT!". (Episdode Title)

Ruriko and Shun were running on their way to school. Ruriko blamed Shun that she would be late for the first time. Shun kept running until he reached the school grounds. Shun turned to Ruriko but saw her walking innocently with fellow students. Ruriko greeted the students good morning and also Shun. Shun teased that Ruriko wore her mask again. Ruriko turned to Shun angrily and yelled. The walking students stopped and looked at Ruriko. Ruriko acted innocently again and to her relief the students went on. The school played the Soap Song ("Let's wash our hands with soap! Germs disappear in a hurry. Even your heart is sparkling clean...") that Tategami High School students could not stand. Ruriko quickly grabbed Shun by the ear and said it was one of AEGIS secret call-ups. Ruriko stopped by a trash bin and threw Shun in it. Apparently, it was one of the secret underground passageway to the base.

At the base, Shirei showed Ruriko and Shun lists of Gate Keeper candidates. The list stopped at Reiko Asagiri an 18 year old high school student. Shun WOW-ed when the screen showed Reiko wearing revealing outfit. The screen continues to play a video account of Reiko's life. Shirei narrated that Reiko had been playing the piano for charity, hospitals, and kindergartens. Reiko was famous for her Dazzling Melody because it was said to produce bewitching illusions. Ruriko asked if Dazzling Melody was related to a gate power. Shirei said it was still unconfirmed and an AEGIS Intelligence detected alien frequency around her house. Shirei assigned the mission to protect her from Invaders and to find out if Reiko Asagiri was really a Gate Keeper as well. Ruriko affirmed Shirei's orders. Shun agreed and said he could not resist to Reiko's beauty. Shirei stopped Shun for awhile because he had something to give to Shun. On the table was an Earth Defense License and a wooden thing. Ruriko explained that the bearer of the Earth Defense License had special freedom to act above the law. Shun picked the wooden thing and inspected it. The wooden thing expanded into a staff. Shirei explained that the staff or the wooden sword had a built-in micro amplifier that was made especially for Shun's gate power. Shun slashed the air with his new wooden sword and said it was cool. However, that was not all. Shirei led Shun to a room with printed figures, "UP-15". The UP-15 wall opened and revealed a metallic blue sports car. The car was a special pursuit vehicle called UP-15 or... A boy with glasses appeared below the car and continued, "...Yotahachi". Shirei introduced the boy as the chief mechanics expert of AEGIS. The boy called himself Megane. (means glasses) Yotahachi rose in an elevator while Megane explained that the car was designed for Shun's gale gate ability. There was sandstorm in the school grounds and the students were complaining that it was always happening in Tategami. The sandstorm was actually hiding Yotahachi's departure. Shun drove Yotahachi with joy.

Ruriko complained that Shun was driving a bit fast. Ruriko remarked that Shun was like his father who liked cars. Shun did not want to hear anything about his father so he hit the gas and drove faster. After a while, Shun was caught by a police officer. The police officer scolded Shun for driving the car fast even though he was still in high school. When the police officer asked for a license, Shun handed his new license. When the officer realized it was the Earth Defense License he apologized and allowed Shun to pass through.

Ruriko and Shun arrived at Reiko's *big* house. Ruriko interviewed Reiko who seemed half-witted. When Ruriko asked what Reiko thinks about UFO and ESP, Reiko replied that she wanted to ride a broomstick. When Ruriko asked about Reiko's Dazzling Melody, Reiko asked back what dazzling meant. Ruriko and Shun got kicked out of the house when Shun asked why Reiko was not wearing revealing clothes. Reiko resumed her piano practice. Ruriko and Shun heard Reiko's piano practice and remarked that the music was wonderful but had a sad feeling. Ruriko and Shun noticed that their surroundings turned into a calm misty lake illusion. Ruriko and Shun agreed to each other that Reiko was a Gate Keeper.

People gathered in the Town Hall, excited to watch Reiko's concert. The Town Hall workers were rude and scolded the people. One of the workers even said he did not understand why so many idiots came to Reiko's boring concert. Another worker complained that because of the concert he was drowned to work.

Reiko peeked from the backstage and noticed the empty reserved. The chairs were reserved for Reiko's parents, but they did not come. Reiko recalled her past when her parents gave the piano to her.
<flashback>A scene of a delighted young Reiko when she received the piano. Reiko turned to her parents to thank them but her parents started to hate each other. Reiko's parents suddenly disappeared from her sight. Reiko called her mother and father but there was no answer.<end flashback>
Ms. Ono (her nanny) told Reiko to prepare and gave her confidence.

Ruriko and Shun also came to the concert to check Reiko. Reiko walked upstage to start the concert. As Reiko played the piano, the auditorium turned into an under sea illusion. The audience relaxed, but the rude workers outside the auditorium dropped down to their knees and covered their ears in pain. The rude workers became Invaders and they went inside the auditorium. The Invaders started firing their bazookas all over the auditorium. The audience ran for their lives (and Ms. Ono was also pushed out by the panicking audience). Ruriko told Shun to attack the Invaders while she gets Reiko. Shun tried to open his gate, but his power would not respond. When the Invaders were nearing Shun, Ruriko attacked them with her arrows. Ruriko told Shun to concentrate harder. Shun tried again but failed. Shun used physical power with his brand new wooden sword. However plain weapons do not work at Invaders. Invaders surround Shun, so Ruriko prepared to attack them. Before Ruriko could attack, she noticed an Invader struggling in pain. Ruriko noticed earplug came out of the Invader's ear and it was suffering because of Reiko's music. More Invaders that Shun hit a while ago fell. Ruriko told Shun to hit the Invader's because Reiko's Dazzling Melody was hurting them. Shun did as what Ruriko said and Invaders started to fall to the ground. A red Inavder appeared and started fusion with the black Invaders. Invaders turned into a huge Stereo. The Stereo produced loud electric guitar noise that overpowered Reiko's Dazzling Melody. Ruriko and Shun were helpless, and Reiko was gasping while she continued to play the piano. The noise overwhelmed Reiko's Dazzling Melody completely. The Town Hall windows started to break and the noise was also heard outside. Megane, who was wearing ear protection, appeared in the control room. Megane waved at Ruriko and Shun and switched the volume to its maximum. Huge speakers around Reiko appeared and Reiko's music re-overpowered the loud electric guitar noise. The Stereo started to throw discs to Shun and Ruriko -- and Reiko's piano. Reiko's piano was destroyed and Reiko opened her eyes. In tears and rage, Reiko released an internal power that did not require the piano. The Stereo was starting to sweat. Apparently, Reiko's power was a bunch of dolls! A cute doll transfromed into a monster doll. The Stereo cracked in fear until the red core was revealed. Ruriko took the chance and targeted the red core.

Shun, Ruriko, and Megane ran to the fainted Reiko. Reiko quickly recovered from Shun's arms. Reiko looked at the auditorium, and at "Ruriko-san" and "Ukiya-san". Reiko remarked it was fun and naively said that she just used magic. Reiko said her childhood dream was to become a witch.
