The Star Lights whom are home again experience a similar dream
Seiya had always loved his Urania and protected her from everything.
As he saw her die at her own hands he breaks down. But they are sent away because Urata discovered Metasephs plan. Their memories are erased and only when the youngest of them (Seiya) reaches the age of twenty will they get their memories back.
On this day the Silver Moon falls.
They are to late. Everybody is dead. They see body of their Princess and knew they failed.
Because of that Failure they are reborn to protect another Princess in another galaxy and only when they achieve their goal they will learn about their past lives with the task to find their Princess Urania and protect her.
Seiya came back to awareness very quickly cause her body tingles all over. As
she stands up she discovers the reason. She is male again.
Seiya runs to his friends and sees that they are also male.
"Hey, Taiki, Yaten why are we male again?"
"I don`t know Seiya but I had a strange dream last night. We three were Knights on the Uranus and protecting our princess..."
"...but she died or so we thought and were sent away. As we regained our memories we went to the Silver Moon Castle to find her and we..." interrupts Yaten
"...failed again and everybody died and now they live on Earth!" finished Seiya.
The three looked at each other.
" Does one of you remember who our Princess is and who she could be now?" Asked Yaten
"No, but we should go back so that we can protect her!" says Seiya
"Princess of Uranus... I think her name was Urania! We should go ask Mamoru, because I remember that he was the brother of our Princess." Taiki concluded.
The made their way to Kakyuu and told her everything they remembered.
"I see... I will miss you my friends but your true Princess needs you now! Please visit me when you found her!" she asks them.
So the three Star Lights make their way back to Earth
