However, years later, the grandson of Yosho, Tenchi, became very curious about a cave where a demon was sealed, as he was told. One day, he stole the key to the cave and went inside to see what the demon looked like. Well...his curiosity got the better of him, and he accidently released Ryoko from her prison. After chasing Tenchi around his school, she finally discovered that she realized that she liked him. Trouble was coming from more than one direction, though, as Aeka, princess of Jurai showed up. Ryoko summoned Ryo-ohki and tried to get away. Aeka overtook her and brought both Tenchi and Ryoko aboard. After meeting Sasami, Tenchi and Ryoko escaped and had a dog fight with Aeka's ship. Ryoko commanded Ryo-ohki to force Aeka's ship back down to Earth. This did not turn out too well as they crashed and took out a major bridge in Tenchi's area.

 After this fiasco, Aeka, Sasami, Ryoko, and Ryo-ohki were stranded on Earth. Aeka and Sasami's ship was destroyed, and Ryo-ohki was injured from the crash. During their stay, Ryo-ohki became great friends with Sasami who cooked many, many carrots for her. Of course, carrots are a cabbit's favorite food. During their stay at an inn owned by a Masaki family friend, they were joined by Mihoshi. Shortly after this, Kagato appeared and kidnapped Aeka. The whole gang went off to save Aeka. Aboard Kagato's ship, Mihoshi managed to find and free an entrapped Washuu.

 After defeating Kagato, they all returned back to the Masaki house. Ryo-ohki spent most of her time wandering between Sasami, Tenchi, and her "mother." After a few more adventures, including discovering that Sasami and Tsunami are the same, a babysitting adventure, and a run-in with a strange doctor and his creation that actually ended up being a part of Ryoko, Ryo-ohki became sad that she couldn't help Tenchi with his chores.

 She went down to Washuu's lab and sat down in front of the tank where the "Masses" were kept. She thought about helping Tenchi as she sat. Suddenly, the "Masses" began to gather behind Ryo-ohki. She turned around and hissed at the "Masses, and then she ran off. Ryo-ohki did not know that the "Masses" respond to the strongest will produced by another "Mass." That will was Ryo-ohki's; thus, all the "Masses" had the wish to help Tenchi. They came together, broke through the tank, and formed something that resembled a human female...only every feature was in the same hue of brown. "She" went out to the fields to help out. Washuu discovered the broken tank and wondered what could have happened. Realizing that Ryo-ohki was the most likely suspect for releasing the "Masses", Washuu hooked her up to a thought-reading device. After discovering that Ryo-ohki had expressed a want to help Tenchi at the time she was near the tank, Washuu figured that the "Masses" had gone out to the fields to help. When the girls and Ryo-ohki got out to the fields, they found out that Tenchi had happened upon the "Masses" in their new form. Washuu quickly explained that if the "Masses" felt that they were threatened, they would discharge a part of themselves at the threat; the discharged part would then explode. Well...the "Masses" found Tenchi to be a threat and were just about to discharge a part of themselves at Tenchi when Ryo-ohki hopped on them and forced them to merge with herself. This caused a reaction to happen, creating a semi-human form that Ryo-ohki could transform into.

 Shortly after she gained her new form, the Masaki residence had a visit from the Jurai royal family. During this visit, the king tried to force Aeka and Sasami to come with him. The princesses did not want to go; therefore, anger began to build. Ryo-ohki tried to ease the tension by displaying a dance that she made with her hands to the king. It did manage to focus the attention of the king away from his anger. After doing her dance twice and getting no reaction from the king, Ryo-ohki began to cry. This got Yosho's mother involved, trying to comfort the cabbitgirl and glaring at the king. The king realized his wrong and comforted the crying Ryo-ohki as well. This cheered her up greatly, and she ran back to sit with Sasami, smiling widely. In order for the princesses to stay, Tenchi had to fight a suitor that the king had chosen. During the duel, Mihoshi crashed into the lake near Tenchi's house, causing a flood that Tenchi had expected and the suitor had not. The suitor was knocked out by the tidal wave caused by Mihoshi's crash, and the king conceded to let the girls stay. The Jurai royal family returned to their planet without Sasami and Aeka.
