After his death, Bai Chuan Yao transmigrates to the world of Overlord. The moment he awakens, he inherits all of Gojo Satoru's powers. The Six Eyes let him see the flow of all magic, while the Limitless technique ensures that no attack can ever touch him. Meanwhile, on this land, the skeletal ruler known as Ainz Ooal Gown is about to embark on a grand campaign to conquer the world, leading the guardians of the Great Tomb of Nazarick. Super-tier magic, armies of the undead, divine-class equipment... The Bone Lord has countless trump cards at his disposal. Bai Chuan Yao slowly raises a hand. "Then let me see whether your magic is stronger, or my Limitless technique has the edge." (A crossover. The story currently takes place in the world of Overlord, with more worlds possibly added later.)
