Tenchi Masaki Is Omnipotent?

On the show it seems that he is beyond omnipotence. In fact Chousin are omnipotent, and they wonder if they can create a superior thing them. It is the paradox of lifting the rock, about the omnipotence. So he would be beyond omnipotence? If he is not omnipotent, or if he is omnipotent, what would be the evidence? Please let you put images.

In addition, what is the relationship between Tenchi Masaki the protagonist of the cartoon and Kami?

Beyond omnipotence is not a thing

It is a vague show, but going by the "Tenchi Muyo: 101 Questions" book, it seems like Tenchi Masaki simply has a link to the supreme being, which will be lost if he dies, and is beyond the power of the Choushin to restore.

Anyway, the Choushin are very powerful, since they were stated to be beyond all dimensional space and time, but we tend to not take statements of omnipotence literally, since it is impossible to prove, especially given that there is an entity above them.
