A group of people, including Vivaan, Ray, Ananya, and others, participate in a worship ritual where they tie holy threads to their wrists. The threads are supposedly magical and can identify those who are not from Earth, but from a realm called Shingkai. However, the threads get mixed up, and it seems like the plan to identify the non-Earthlings has failed. But Vivaan reveals that he has used his "ultra-power vision" to identify the magical threads. The threads are supposed to change color to green and cause the wearer's hands to burn if they are guilty. The group waits for the threads to take effect, and soon, the color of the threads on some individuals starts to change, indicating that they are not from Earth.
