Spirit and Spatial Magic, Arifureta Vol 10

Spatial magic was magic that manipulated boundaries. Meaning it could be used to create entire dimensions
...
Spirit magic was magic that manipulated the incorporeal elements of sentient beings. In more concrete terms, it could be used to manipulate the heat, electricity, and other matterless energy that circulated within a person’s body.
That also included things like memories, thoughts, and consciousness. With enough skill, a spirit magic user could take those incorporeal elements, duplicate them, and create a new soul out of them.
In other words, create another person.
