D3 is an inter-dimensional being that supervises 3-dimensional space in the Tenchi Muyo! world, including the universe that the show takes place in. He seems to take the appearance of a bearded humanoid man, projected from a large ovoid crystal.

Little is known about D3 other than that he serves Tokimi, one of the three Chousin. The other two Chousin, Washu and Tsunami also have authority over him as well, as shown in OVA 3.

It is not known to what extent D3 (or the other dimensional stewards) exercises free will, or if he is an automation. When he asks Tokimi "what to do with Dr. Clay," she responds with "I believe this dimension is under your jurisdiction," indicating that he not only has some authority to take action without consulting Lady Tokimi, but that she expects him to do so.

He doesn't appear to have a direct link with Tokimi, as he interacts with her using normal spoken language.
