The First Day of the End of the World (世界の終わりが始まる日 Sekai no Owari ga Hajimaru Hi) is the sixteenth episode of Ultraman Geed.
Laiha has once again in possession of a Little Star. However, an Alien Godola attempts to kidnap her, and the all of the other Little Star carriers, but Ultraman Geed appears to protect them. Meanwhile, Belial finally returns to Earth.
After tearing his own dimension, Belial made his way to fetch Geed. Despite everything Geed had done, a lot of people still had their doubts for the new Ultra Warrior. Laiha experiences hand feverish and a strange voice warns her of Belial's arrival. While training outside, Laiha finally revealed her possession of Little Star and AIB officers picked her to a special building where three other Little Stars were contained and protected from being hunted. As the headquarters deliver a message, Zenna was forced to have Godo Wynn handling the rest.
Troubled by Laiha's warning, Riku take the available time to meet Zero, revealing of his true heritage and ask for advises. Zero can only assure that Riku is in control of his own fate while he still have his friends to rely on. Laiha remembered that she contacted the Little Stars as a child before it lost to Skull Gomora's rampage. Moa theorized it to be approximately more than six years before that Kei disperse the Carellen Element to outer space and caused the Little Star phenomenon to occur. Tri also mentioned that they are currently developing an enzyme which allows the removal of Little Stars without ill effect.
At the command center, an alien holds Zenna at gunpoint and Godo Wynn quickly shots Tri, forcing her and Laiha to unlock the Little Stars before Zenna freed from his captor. When Laiha begins to counterattack, Godo was revealed to be the same alien race that try to ambush Zenna and enlarges, attacking the city in mad fury. Geed tried to fight Godo, but their battle were interrupted by Belial, who killed Godo with relative ease and try to fetch his son. Geed becomes determined to fight his own father despite Zero's insistence to back down and barely even lay a scratch to the latter. Through a pair of Kaiju Capsules and a Riser, Belial transforms into Chimeraberus, kidnapping his son before leaving Earth. At the AIB shelter, Laiha learned that Chimeraberus is currently positioned on the Moon and slowly consuming Geed in the process.
