One of the three Choushin in the Tenchi Muyo OAVs
Tokimi is one of three hyper-dimensional beings called the Choushin who were responsible for the creation of the Tenchi multi-verse and capable of existing in multiple dimensions. Following their creation of the universe, Tokimi and her sisters were curious over the existence of a higher being in the multi-verse that possessed far greater power than the three. While Washu and Tsunami separated from Tokimi to persue their own objectives in bringing out this higher being, Tokimi took a more direct method by creating anomalies throughout the universe in hopes of drawing out this higher being. It was her actions that would lead to the manifestation of Z's power over the Light Hawk Wings and lead him to serve as her protege.
Upon realizing that Washu and Tsunami might have succeeded in drawing out the higher being with Tenchi, Tokimi appointed Dr. Clay the task of bringing Washu to her to learn if she made any success. Instead, Dr. Clay had his own plans of revenge on Washu and upon realizing Clay's motives, Tokimi ordered her assistant D3 to wipe Clay of any memories the man had of her. She then appointed Z to observe her sisters and Tenchi without inflicting harm on Tenchi. However, Z's jealousy of the interest Tokimi had on Tenchi drove him to trigger a series of events that eventually led to his later attempt to kill Tenchi and have the Choushin resurrect him without his powers. Tokimi attempts to contain Z, but Z's battle against Tenchi eventually leads the boy's power to surge out of control threatening to destroy the entire multi-verse. Tokimi and her sisters then try to contain Tenchi's power until Tokimi is attacked by the "counter-actor" Misaki who attempts to kill Tokimi. However, Misaki gets calmed down by Tenchi-kami-sama and the Choushin succeed in containing Tenchi's power. Feeling regret over the neglect she gave Z, Tokimi reset time so her actions would not influence Z's later manifestation and hoped that she would be able to meet Z once again.
