In the first TV series, Tenchi Universe, Tenchi is similar in personality to the Tenchi of official canon, but is not as powerful as his counterpart. His abilities seem to not go beyond his use of Tenchi-ken (Sword Tenchi) and the power possessed by members of Jurai's Royal Family. Sword Tenchi is just a weapon and is not revealed to be a Master Key. Tenchi attends school in the city, but it is a long commute for him because he lives in the mountains of Okayama near his family's shrine with his widowed father, Nobuyuki, and his grandfather, Shinto priest Katsuhito.
