Ayeka arrives to Earth to find Ryoko, whom she sees responsible for the disappearance of her half-brother, Yosho. Back on Earth, Ryoko is trying to get Tenchi to transfer the three gems on his sword back to her. After heavy convincing, Tenchi transfers one of the gems back to Ryoko allowing her to summon her spaceship, Ryo-ohki, which comes just in time as Ayeka attacks Tenchi's house. As Ryoko and Tenchi are about to flee, Ayeka immobilizes Ryo-ohki and has her guardians, Azaka and Kamidake, capture them. Ayeka then interrogates Ryoko about her brother's whereabouts and departs for sleep.
Meanwhile, Tenchi gets freed from his prison by Ayeka's younger sister, Sasami, who offers to get Tenchi back home if he stole Ayeka's head ornament. Instead, Tenchi tries to get back his sword from Ayeka. Instead, he winds up waking the princess up as she summons Azaka and Kamidake to attack Tenchi. He and Sasami run into Ryoko's prison where they free her. Ayeka then finds them as she asks Tenchi about Yosho's whereabouts. He tells her that Yosho is dead. Ayeka gets mad from this news and is about to have Azaka and Kamidake attack Ryoko and Tenchi. However, Tenchi's sword sets off one of Ayeka's ship security systems which restrain the two guardians. Ryoko and Tenchi head back into Ryo-ohki as Ryoko crashes Ayeka's ship into Earth. The next day, Ayeka tries to repair the damage on her ship but to no avail.
