Log-in Murim 

When an interdimensional portal appeared and released countless monsters across the world, humanity didn’t take the threat lying down. Mankind fought back, defeating the monsters' Demon King and creating a new way of life as "hunters." But when Taekyung Jin, a struggling, low-ranked hunter, accidentally logs into a game on a beat-up VR console, he finds himself trapped in an all-new world, unable to log out. (Source: Tapas)
