is the main protagonist of the Tenchi Muyo! series. Tenchi's name means 'Heaven and Earth'. It is the same as 'Tenchi' in the Shinto Kojiki which contains some of Japan's oldest myths and legends.
In the OVA-based continuities, Tenchi is the first prince of Jurai and the grandson of a Jurai prince named Yosho and an Airaian priestess named Airi. He gains possession of a 'Master Key' called 'Tenchi', also known as the Tenchi Sword (Tenchi-ken), that can form a lightsaber-like blade. He later receives a special ring from Tsunami that can create a Juraian battlesuit for him and acts as a 'Guardian System', protecting him. Tenchi also has the innate ability to create kou-ou-yoku ('Light Hawk Wings')(believed to be the only non-ship entity able to do so until encountering Z in OAV3), and the ill-defined ability of Material-Energy Conversion. Tenchi initially lives in the city with his father to attend school and visits his grandfather's shrine every summer, where he trains to become a Shinto priest and learns his family's special style of swordsmanship (which happens to be particular to members of Jurai's Royal Family). The house is permanently relocated next to the shrine after a battle between Ryoko and Ayeka, and Tenchi lives in the house with the girls while refusing to get intimate with them. Tenchi no longer attends school, after the school was decimated during the encounter with Ryoko in OVA 1.
Tenchi suffers a great deal of stress as he tries his hardest to be a gentlemen while most of the women within the household will take the opportunity to display their attraction for him. In the third OVA series Tenchi is discovered to be engaged to Noike (aunt of Ayeka and Sasami). The arrangement was done by Tenchi's great great grandmother, known better as the "Devil Princess of Jurai" Seto Kamiki Jurai. Tenchi also found out around this time that he has an 80-year old sister named Tennyo Masaki, who looks like his late mother, Kiyone. Tenchi then learned from his grandfather, Katsuhito, that since Earth is a developing civilization, the Masaki clan must keep their true presence hidden since they do not age at the same rate as Earthlings, and those who are born into the Masaki family are also kept from these secrets until they come of age which is when they reach adulthood. After a climatic battle between the three Goddesses, the truth behind everything has happened was linked to the three. They decided to change the time line in order to repair the damage that they have done, and Tenchi, in his changed time line, doesn't get to meet Noike. However, Noike, along with Fuku, traveled into the past and altered the message Mihoshi was to send to her family (the message was originally altered by Z) so that she would meet Tenchi.
Tenchi is the most powerful character in the series, but is too young and immature to have full control over his Light Hawk Wings and other abilities. He is a competent swordsman and martial artist capable of superhuman feats thanks to his Juraian blood, but has only displayed his more unusual talents during dire situations, such as his duel with Kagato, the escape from a black hole, and the final confrontation with Z. The extent of Tenchi's powers is unknown; at one point they rage out of control, forcing the Goddesses to step in and prevent a catastrophe (in the new "altered" timeline, when Noike secretly fired the Choubimaru's cannon to collide with the Earth, again to preserve her future, Tenchi projects his Light Hawk Wings to stop it, a total of six wings, rather than the usual 3 wings he had before event.)
