The fourth season, which aired in 2018, starred Sriti Jha as the lead naagin. This season had a new storyline, with the naagin fighting against evil forces.

The prophecy of the 7th Naagin was fulfilled—not in blood, but in sacrifice. Shivanya did not kill Rudra. She stripped him of his power and exiled him to wander the mortal world, remembering the face of mercy.
