Both set in fantasy-like worlds. "Arifureta Shokugyou de Sekai Saikyou" has a MC that gets summoned to a new world along with his classmates, but it turns sinister quickly as someone purposely pushed him into a pit and he became savage for survival. "Yasei no Last Boss ga Arawareta!: Kokuyoku no Haou" is more about a guy being stuck in a game world as his female character.
