Alien Semon Meed chased by Alien Pedan thugs that a man hides behind a trash can. As the thugs searching him, they electrocuted by Kirisaki using electric shock off-screen that he looks him. Kana worked overtime that she is finally done. As she goes home, Meed went to the HQ that he meets her again.
He eats Japanese foods, much to the members watching, she tells that she once arrested him four times during her time in Foreign Affairs X. She tried to get him a job and had conversation groups to help Meed. Over the years, he had turned to a life of crime, making a living by cheating and stealing from others. He needed to meet with a "contact", so he went to the company to get them to escort him, lying to Kana about the circumstances, saying that he needed to go back to his planet after letting out a few Villain Guild secrets. They bring him to Ario, near the rendezvous point. After causing some trouble and letting both Hiroyuki and Homare know about Kana's incident with Cicada girl, he helps up a little girl who had fallen. Suddenly, the Alien Pedan attack, so Kana escorts him to the rendezvous point while Homare and Hiroyuki fight off the thugs.
He met up with his contact, Alien Ckalutch Hoshijin, who wanted to buy the monster-controlling device that Meed stole from Villain Guild, much to Kana's shock, who had been lied to. They are attacked by more Alien Pedan, but in the commotion, Kirisaki suddenly appears and kills a Pedan. To make things worse, he suddenly summons the Molten Iron Monster, Demaaga, just to force Hiroyuki to choose between saving his friends or the city. He transforms into Taiga to fight Demaaga. This started a brawl among them and the members, who were escorting Meed unaware of his true intentions.
After a short fight, Taiga throws Demaaga away to buy some time for him to fuse into Tri-Strium. Taiga proceeds to have a one-sided battle against Demaaga and finishes it off with the Taiga Blast Attack. Ckalutch and Pedan arrested by police that Meed arrested by the authorities. He sees something coming towards Kana and pushes her out of the way, and is hit fatally by an energy bolt. He dies immediately, having been "accidentally" shot by none other than Kirisaki. Back inside the HQ, Hiroyuki tells Taiga that the truth about Meed's death, much to Kana horrified. He met by Kirisaki once again that his final decision put those precious friends of him in danger. He alternatively transforms into Tregear that he introduces his name to Hiroyuki, much to Taiga shocked. Before the dark hero left, Hiroyuki and Tri-Squad will never lose!
