Tenchi Muyo! GXP
Nothing is known about his early life, but he joined the Galaxy Police and was assigned to Jurai. Custom on Jurai said that an incoming cadet go through a staged trial, by which they save a girl from a group of drunks. When Kazuki arrived, he saw a young woman being assaulted by drunk men and went to rescue her. However, this was not the custom event, as Amame quickly realizes and moves in to save him. Afterwards, she asks why he did not have his gun, to which he answered that he didn't want to risk shooting anyone. Amame then decides to train him in Juraian martial arts, and soon falls in love with him. Once his tour of duty is over, Amame decides to marry him, at the cost of her royal status. They went off together and had a son, Azusa. He and his wife appeared briefly in Tenchi Muyo! GXP.
- Kazuki shares his name with the main character of Dual! Parallel Trouble Adventure, another series set within the Tenchi Muyo canon. Whether this means that they are parallel counterparts to each other has not been revealed.
