==Synopsis==
Someone new tries to join EGIS, but following Zetton's recent attack, he harbors hatred towards aliens. Kirisaki uses this situation to his advantage, as part of a greater plan to bring calamity to the planet.
==Plot==
During Zetton's attack, Osamu Tasaki's mother, Asuka, was injured and had to be hospitalized. But then, Kirisaki came to save him during the incident.
During the interview in the HQ, Osamu tells Kana that he wanted to join so that he could defeat aliens, but he is told that the work of the company is to protect the client, no matter who they are. He is allowed to work on probation and is assigned as Hiroyuki's junior. He steals CQ that he can search for aliens by himself. He visits his mother in the hospital, where Kirisaki waiting for him. He tells Osamu that he noticed "someone suspicious", and asks to follow him. Members surprised the missing CQ that it is gone so they search. Kirisaki and Osamu use CQ to identify Alien Ghose, became a street cart vendor and sold food to people in the park, and corner him. Pirika found the CQ detected that Hiroyuki left, followed by Homare. Kirisaki approaches first and whispers to Ghose, asking to borrow the drill missile on his spaceship, but the request is denied and he is pushed over. Seeing this, Osamu chased Ghose into the forest. Ghose was tackled to the ground and attacked by Osamu, accusing him of a crime he did not commit. Then, Hiroyuki saw Kirisaki that newbie seems pretty promising. Homare confronts Osamu when he pins down Ghose for seemingly no reason other than it being an alien, but Osamu does not listen. Ghose knocks out Homare and speaks to Osamu through him, explaining that he didn't do anything wrong. Osamu still refuses to listen and electrocutes him. Hearing its master in distress, the Twin-headed Monster, Pandon, emerges from inside a mountain. It blasted out countless fireballs in rage before coming to threaten the group.
Ghose tells Osamu that he and Pandon are the same; angry because someone hurt their parent. Hiroyuki transformed into Taiga and proceeded to battle the kaiju. Taiga was forced to let up when Osamu lets go of his grudge and released Ghose. Most of it was deflected, but eventually broke through and got him to release so he could calm Pandon. He spoke to the monster and it finally became docile; however, there'd be no happy ending. Kirisaki transformed into Tregear, he flew over and sliced the docile Pandon into many pieces before the remains exploded. Ghose collapsed to his knees in shock and sadness at the death of his companion. At soon, Taiga fused into Tri-Strium before performing Fuma Raging Fire Slash, that Tregear disappeared before transforms back into Kirisaki. Hiroyuki raced to Kirisaki that the underground missile starts digging the ground before reaching the core. He tells about five elements: fire, water, wind, land, and... ether? Once as the underground missile reaches the core, the shockwave occurs Earth's ether as a beacon that a comet comes before he disappears. In the sunset, Ghose set up a small grave to mark Pandon's death site. He gave a farewell to the members and Osamu before leaving the Earth at sundown, all of them watching his ship. Meanwhile, the comet still coming to Milky Way.
