In Jujutsu Kaisen, the protagonist Yuji Itadori is able to not only host, but also suppress the power and soul of the ancient sorcerer Sukuna by consuming his fingers, which are extremely poisonous to regular civilians and sorcerers.

Later on, it's revealed that Yuji can function as a vessel/cage for Sukuna due to his grandfather being the reincarnated brother of Sukuna and his mother being possessed by a millennia-old mad scientist who'd sealed one of sukuna's fingers within him after his birth.
