Premieres January 2025. The new PV is here. Check out the ANN article for additional information. Synopsis for the first season from AniList:
They say whatever doesn’t kill you makes you stronger, but that’s not the case for the world’s weakest hunter Sung Jinwoo. After being brutally slaughtered by monsters in a high-ranking dungeon, Jinwoo came back with the System, a program only he could see, that’s leveling him up in every way. Now, he’s inspired to discover the secrets behind his powers and the dungeon that spawned them.
I know the story isn’t really that interesting, and the anime adaptation isn’t that brilliant, but I’m still excited. Solo Leveling is good at hyping me up and the hype only goes up from here.
