_History_

For the past week, Team Daiku Maryu has been detecting signals coming from Deep Space – Midori in particular feeling these the most, believing are meant for her specially; while the concern of been a Zelan Ploy is possible, the signals come from the direction of the Scorpio Constellation. Meanwhile, in Zelan, the Generals give a demonstration of the Instantaneous Nuclear Freeze to Emperor Darius – a weapon that freezes anything to the point of Brittleness; pleased with the results, Darius allows them to install it on the Freezing Monster Ice Killer, another Dark Horror Kaiju left behind on Earth in the ancient Past.

Returning to Earth, the Generals awaken the Ancient Robot Kaiju from its Millennia long Antarctica slumber and is order to attack a cigar shape Spaceship – neither from Earth or Zela – as a test of its new powers, but when trying to do so, the ship was immune and repelled the monster with its energy shield, to the shock of the Four Generals; who then decided to see what it does, when they detect the Daiku Maryu heading to the site of the Monster emergence after learning of the news; the team chooses to lands near Boso, in an attempt to have the enemy their eyes on them, while avoiding harm to innocents.

As they wait from any action by the Zelans, the group receive another signal, now with a different wave pattern, and this time the message is sent to Green – Midori's true name – and its coming from none other than her own mother, an alien from Planet Pigeon wondering why hasn't she answer back her other signals; now that the people of Pigeon have found a new planet to live, she informs her another fellow, Paul, will come to pick her up the the following day in the Afternoon.

After learning the the content of the message, Daimojin tells everyone how he found Midori 10 years prior in front of his home, with little memory, but mumbling about Planet Pigeon and Black Holes, still raised her as a daughter, while long having suspicion she was an alien, the shock of been left behind having provoked her amnesia, yet chose not to tell the others about it. Afterwards, he asks the members to leave Midori alone for the night, but coming the next day, to hold smiles for her when she departs.

After a minor mishap with Midori falling into the Sea and everyone jumping in to rescue her (though saved by Daimojin), the Daiku Maryu rendezvous in space with the Alien from Pigeon, Paul, an old childhood friend of Green as Midori bids farewell to her Team mates – interestingly he sends a signal about the lack of Anti Freezing technology in the hull of the Daiku Maryu; Paul explains to the crew of the misfortune that had befallen his old Home world, having been consume by a Black Hole, which sounds oddly familiar to another Planet in the same plight. As the People of Pigeon moved on searching worlds to inhabit, they left others behind like Midori, to fend off extinction just in case anything happened, but most contained inhabitants of their own they couldn't claimed, until their long trek let to a world they could live in.

After thanking them for keeping care of her, Paul takes Midori and leaves on rush; as the ship departs, Midori looks at her team mates bidding farewell from the ships Portholes. As they fly back to the Main Pigeonian Ship, Paul explains their trek back to their new home will be will take 10 Years, as it is located 200,000 Light years from Earth, on the edge of the Galaxy, when they stumble upon Ice Killer heading towards the Daiku Maryu. To her shock, Paul explains that no harm will come to them as an agreement exist between the Zelans and Pigeonians, which was basically, selling off the Daiku Maryu for safe passage – a detail that is contradicted by the fact the main Pigeon Ship was able to fend off the attack from early ... PLOT HOLE. Ice Killer then proceeds to attack the Daiku Maryu, whose weapons are ineffective on the Beast; the monster proceeds to use its Power to freeze the entire vessel, its internals heaters unable to fend off the cold; the crew wears thermal suits, but still, they enter into a deep slumber produced by the cold.

Realizing she could not leave her friends behind, Midori splits the Transport Pod, bids farewell to Paul with a kiss, and flies back to save her friends in the Daiku Maryu, which the Beasts had begun to tear apart a bit at a time when Midori shows up and repels the monster; she then fires an Anti-freezer beam that frees the ship from its frozen trap and awakens the crew: Gaiking is launched and assemble, and Ice Killer goes after it but is pinned when the Daiku Maryu makes its Volution Protect, partially denting its body; when released, Sanshiro disposes of the monster with Saur Geyser.

Afterwards, having rejoined the Crew, Midori looks out the window to the Constellation of Scorpio, where her mother is, with one of the stars of the Constellation glowing brighter than the others.
