Ryu-Oh has the ability to produce three kō-ō-yoku ("light-hawk-wings"). Ayeka had bonded with the ship shortly before Ryoko and Ryo-Ohki attacked the Juraian castle, Tenju. Despite warnings made by the castle's attendants, 14-year-old Ayeka launched the young, underdeveloped ship to fend Ryoko's attacks. According to the True Tenchi Novels, "Ayeka had just finished the selection ceremony and didn't have the key to help her connect with Ryu-oh. Also her ship had just equipped, thus was not fully synchronized with the external armor, so Ayeka and Ryu-oh could not fully control the power of the Royal tree. But Ayeka did not give up and continued the battle. However, she could not help the situation just by defending herself. It was only by virtue of the second generation Royal tree's power that she could hold off the attack, and it was also because Ryo-ohki and Ryoko were just teasing her and not fighting with full power." Ayeka was also able to use the light-hawk-wings to attack (though their purpose is for defense) and was able to hit Ryo-ohki, which no other ship could do. This feat is noted by Noike when she speaks to Tenchi in OVA 3.
In the Tenchi Muyo! episode 2, Ryu-Oh is damaged in a crash landing on Earth after an escape attempt by Ryoko. It did begin to regenerate, but it was blown away by Kagato's ship, Sōja. However, due to help from Tsunami, Ayeka received a seed that will grow into a new Ryu-Oh.
