So let me get this straight.
When Takamagahara released Terumi from the Boundary, they only released his ghost form and left the Kazuma body sealed. Relius then made a second body, Hazama, for him. For some reason during the story, Trinity transferred Terumi back to the Kazuma body and that is the Yuuki Terumi we play as. Hazama, who has a mind and personality of his own, is then left in control of his own body again.
Is this correct?
