Haruna and Yosho left Jurai for the Earth to have a better life together (as Haruna was not royalty, they could not marry on Jurai. However, they were forbidden to love, so they ran away.) However, the journey was a difficult one, and as a result Haruna fell gravely ill. Tragically, she passed away just before they arrived on the Earth.
Saddened over losing her, Yosho buried Haruna's body on the grounds of what would be near the Masaki Shrine, along with Haruna's camellia tree. He was surprised to see that the tree began to flourish there and subsequently took cutting from the tree, planting them around Japan to show Haruna the world they had planned to spend their lives together in.
However, on one of these journeys, he had met a girl named Itsuki and later, they were married then together the two had raised a daughter, Achika, who in turn had a son, Tenchi. Somehow, Haruna's spirit became disturbed that Yosho had found happiness without her as she felt betrayed that Yosho had married with a human girl and have a daughter.
However, after that, Tenchi forced Haruna to confront her past with Yosho.
Meanwhile, Yosho saw that the camellia tree was still blooming in fall and decided to destroy it, thereby allowing Haruna to rest. It was only then that Haruna acknowledged that she had been wrong about taking Tenchi away, and she finally let him go. After being persuaded by Ayeka, Ryoko went back to the dimension and rescued Tenchi right before it collapsed upon Haruna's departure.
- The relationship between Yosho and Haruna on Jurai sounded like a reference to Romeo and Juliet in comparison to which Haruna was never royalty except for Yosho whose royalty was unequal to Haruna's.
- The name "Haruna" in Japanese means "Spring Flower", most likely indicating that Haruna was probably born in the spring.
