Tenchi Masaki is the crown prince of Jurai and the grandson of a Jurai prince named Yosho and an Aiaraian priestess named Airi. Tenchi suffers a great deal of stress as he tries his hardest to be a gentleman while most of the women within his household will take the opportunity to display their affection for him.
Tenchi initially lived in Orange Star City with his father while attending 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 the Jurai Royal Family).
Tenchi is the most powerful Juraian known so far, but is too young and immature to have full control over his abilities. Tenchi has the innate ability (making him unusual as the only non-ship entity able to do so) to create 'Light Hawk Wings'. He has possession of a 'Master Key' called 'Tenchi-ken,' or Tenchi Sword, that can form a lightsaber-like blade. He later receives a special ring from Tsunami-kami-sama that can create a Juraian battlesuit for him and acts as a 'Guardian System', protecting him.
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.
