Alienoid: Return to the Future

Representatives from different eras continue to fight against evil aliens. In the time of Goryeo, an adult Y-an searches for a robot assistant after obtaining the Divine Blade; a pair of mages tries to figure out who is living in Mu-ryuk's body; a blind warrior seeks a way to regain his sight; and aliens disguised as humans desire to return to the future, which is why they need the Blade. Meanwhile, in 2022 Seoul, a police officer named Min Ga-in pursues a drug dealer, leading her closer to uncovering an insidious alien plan.
