Tenchi Masaki' s Lecherous Father.


In most continuities of the Tenchi Muyo franchise, Nobuyuki is the father of Tenchi Masaki and son of Katsuhito Masaki, working as an architect. He is usually portrayed as a pervert, trying to peep on the girls that become a part of Tenchi's extended family in the Masaki household.


Nobuyuki was created as a supporting character for Masaki Kajishima's Tenchi Muyo anime, manga and novel franchise. There is no information about his character known during development of the series. Nobuyuki has appeared in a number of anime, manga and novel adaptations of Tenchi Muyo which include the OVA series and several spinoff titles. For anime adaptations, he was voiced by Takeshi Aono in Japanese for all anime appearances and by Toshiyuki Morikawa for his younger self from Tenchi Muyo in Love. For English, he was voiced by Jay Hopper for the first two OVA titles and Tenchi Universe; Bob Pappenbrook for the third OVA series and Tenchi in Tokyo; and Andrew Philpot for Tenchi Muyo in Love.



In spite of appearing middle-aged in the OVA series, Nobuyuki is actually over 200 years old due to being part-Juraian. He has black hair and eyes, normally seen to be wearing glasses.


Nobuyuki is a hard-working man who has worked hard at raising him since the death of his wife. However, he is somewhat irresponsible as he is a bit of a pervert willing to peep on the female residents and trying to encourage Tenchi to become involved in his antics.


Tenchi Muyo OVAs

Note: Some of the information included in this section comes from one of three novels written by Tenchi Muyo creator Masaki Kajishima called the Shin Tenchi Muyo! Ryo-ohki! Novels, which cover details on characters and elements of the series not explored within the OVA series.

Nobuyuki is a distant descendant of crown prince Yosho, being born to his first wife Kasumi. Learning of his family heritage later in life, he would become a decorated Galaxy Police detective, who had a brief romantic fling with the mother of Z. Due to his diluted Juraian heritage and having undergone body enhancement from his time in the Galaxy Police, Nobuyuki has lived for centuries. He would marry Katsuhito's daughter Kiyone and give birth to two children, Tenchi and Tennyo. Unfortunately, Kiyone died while Tenchi was a child.

He and Tenchi originally lived together in the city until Ryoko's battle with Ayeka led their house to be permanently relocated next to the Masaki family shrine. Nobuyuki would return to the city where he lived in an apartment with his assistant, Rea. The two would become engaged and get married towards the end of the third OVA series, later having a child named Kenshi.

Tenchi Universe

Nobuyuki retains his character traits from the OVA series, but had married into the Masaki family when he became betrothed to his wife Achika. While he does travel with Tenchi and the girls to Jurai, he has little role to play in the events of the TV series.

He gets a somewhat bigger role to play in the Tenchi Muyo in Love movie when Tenchi and the girls travel back in time to 1970 to prevent Kain from killing Achika to alter events in the future. Compared to his sleazy perverted self decades from now, Nobuyuki was a shy young man with a talent for drawing as he liked to draw houses and also loved to record Achika on a video camera, despite both being shy to express their feelings towards one another. When he is being beaten up by Kain later in the film, the sight triggers Achika's hidden Juraian power. The two are rescued by Tenchi, Ryoko and Ayeka; and later have their memories erased to prevent the future from being affected.

Tenchi in Tokyo

Nobuyuki is somewhat different here as he lacks the perversion of earlier takes of his character and is a supportive father to Tenchi with his son's best interests in mind, playing a role in helping to settle tensions between him and Sakuya during the middle of the series.

Pretty Sammy

Nobuyuki makes an appearance in episode 10 of Magical Project S as Nobuyuki Onijigoku, a rival of the Hagakure clan trying to force their leader Genjuro out of his ninja theme park to convert it into a Western-style theme park. While able to get help from Genjuro's son Binpachi and Pixy Misa, his plans are thwarted by Pretty Sammy. While Genjuro does agree to allow for development of a ninja/ western theme park, he does tie up Onijigoku and his assistant to the theme park entrance as punishment for his actions.
